* 3D point.

* So the choice was between "Point" and "Vector3", the first one looked better (IMHO).

* Some people, then, use a typedef to handle both points & vectors using the same class: typedef Point Vector3;

/**
|
||||
* 3D point.
|
||||
*
|
||||
* The name is "Point" instead of "Vector" since a vector is N-dimensional, whereas a point is an implicit "vector of dimension 3".
|
||||
* So the choice was between "Point" and "Vector3", the first one looked better (IMHO).
|
||||
*
|
||||
* Some people, then, use a typedef to handle both points & vectors using the same class: typedef Point Vector3;
|
||||
* This is bad since it opens the door to a lot of confusion while reading the code. I know it may sounds weird but check this out:
|
||||
*
|
||||
* \code
|
||||
* Point P0,P1 = some 3D points;
|
||||
* Point Delta = P1 - P0;
|
||||
* \endcode
|
||||
*
|
||||
* This compiles fine, although you should have written:
|
||||
*
|
||||
* \code
|
||||
* Point P0,P1 = some 3D points;
|
||||
* Vector3 Delta = P1 - P0;
|
||||
* \endcode
|
||||
*
|
||||
* Subtle things like this are not caught at compile-time, and when you find one in the code, you never know whether it's a mistake
|
||||
* from the author or something you don't get.
|
||||
*
|
||||
* One way to handle it at compile-time would be to use different classes for Point & Vector3, only overloading operator "-" for vectors.
|
||||
* But then, you get a lot of redundant code in thoses classes, and basically it's really a lot of useless work.
|
||||
*
|
||||
* Another way would be to use homogeneous points: w=1 for points, w=0 for vectors. That's why the HPoint class exists. Now, to store
|
||||
* your model's vertices and in most cases, you really want to use Points to save ram.

You could use a complex sweep-and-prune as implemented in I-Collide.
|

You could use a complex hashing scheme as implemented in V-Clip or recently in ODE it seems.

You could use a "Recursive Dimensional Clustering" algorithm as implemented in GPG2.

Or you could use this.

Faster ? I don't know. Probably not. It would be a shame. But who knows ?

Easier ? Definitely. Enjoy the sheer simplicity.

You could use a complex sweep-and-prune as implemented in I-Collide.
|

You could use a complex hashing scheme as implemented in V-Clip or recently in ODE it seems.
|

You could use a "Recursive Dimensional Clustering" algorithm as implemented in GPG2.

Or you could use this.

Faster ? I don't know. Probably not. It would be a shame. But who knows ?

Easier ? Definitely. Enjoy the sheer simplicity.

/**
|
||||
* An hybrid collision model.
|
||||
*
|
||||
* The problem :
|
||||
*
|
||||
* Opcode really shines for mesh-mesh collision, especially when meshes are deeply overlapping
|
||||
* (it typically outperforms RAPID in those cases).
|
||||
*
|
||||
* Unfortunately this is not the typical scenario in games.
|
||||
*
|
||||
* For close-proximity cases, especially for volume-mesh queries, it's relatively easy to run faster
|
||||
* than Opcode, that suffers from a relatively high setup time.
|
||||
*
|
||||
* In particular, Opcode's "vanilla" trees in those cases -can- run faster. They can also use -less-
|
||||
* memory than the optimized ones, when you let the system stop at ~10 triangles / leaf for example
|
||||
* (i.e. when you don't use "complete" trees). However, those trees tend to fragment memory quite a
|
||||
* lot, increasing cache misses : since they're not "complete", we can't predict the final number of
|
||||
* nodes and we have to allocate nodes on-the-fly. For the same reasons we can't use Opcode's "optimized"
|
||||
* trees here, since they rely on a known layout to perform the "optimization".
|
||||
*
|
||||
* Hybrid trees :
|
||||
*
|
||||
* Hybrid trees try to combine best of both worlds :
|
||||
*
|
||||
* - they use a maximum limit of 16 triangles/leaf. "16" is used so that we'll be able to save the
|
||||
* number of triangles using 4 bits only.
|
||||
*
|
||||
* - they're still "complete" trees thanks to a two-passes building phase. First we create a "vanilla"
|
||||
* AABB-tree with Opcode, limited to 16 triangles/leaf. Then we create a *second* vanilla tree, this
|
||||
* time using the leaves of the first one. The trick is : this second tree is now "complete"... so we
|
||||
* can further transform it into an Opcode's optimized tree.
|
||||
*
|
||||
* - then we run the collision queries on that standard Opcode tree. The only difference is that leaf
|
||||
* nodes contain indices to leaf nodes of another tree. Also, we have to skip all primitive tests in
|
||||
* Opcode optimized trees, since our leaves don't contain triangles anymore.
|
||||
*
|
||||
* - finally, for each collided leaf, we simply loop through 16 triangles max, and collide them with
|
||||
* the bounding volume used in the query (we only support volume-vs-mesh queries here, not mesh-vs-mesh)
|
||||
*
|
||||
* All of that is wrapped in this "hybrid model" that contains the minimal data required for this to work.
|
||||
* It's a mix between old "vanilla" trees, and old "optimized" trees.
|
||||
*
|
||||
* Extra advantages:
|
||||
*
|
||||
* - If we use them for dynamic models, we're left with a very small number of leaf nodes to refit. It
|
||||
* might be a bit faster since we have less nodes to write back.
|
||||
*
|
||||
* - In rigid body simulation, using temporal coherence and sleeping objects greatly reduce the actual
|
||||
* influence of one tree over another (i.e. the speed difference is often invisible). So memory is really
|
||||
* the key element to consider, and in this regard hybrid trees are just better.
|
||||
*
|
||||
* Information to take home:
|
||||
* - they use less ram
|
||||
* - they're not slower (they're faster or slower depending on cases, overall there's no significant
|
||||
* difference *as long as objects don't interpenetrate too much* - in which case Opcode's optimized trees
|
||||
* are still notably faster)

/**
|
||||
* An hybrid collision model.
|
||||
*
|
||||
* The problem :
|
||||
*
|
||||
* Opcode really shines for mesh-mesh collision, especially when meshes are deeply overlapping
|
||||
* (it typically outperforms RAPID in those cases).
|
||||
*
|
||||
* Unfortunately this is not the typical scenario in games.
|
||||
*
|
||||
* For close-proximity cases, especially for volume-mesh queries, it's relatively easy to run faster
|
||||
* than Opcode, that suffers from a relatively high setup time.
|
||||
*
|
||||
* In particular, Opcode's "vanilla" trees in those cases -can- run faster. They can also use -less-
|
||||
* memory than the optimized ones, when you let the system stop at ~10 triangles / leaf for example
|
||||
* (i.e. when you don't use "complete" trees). However, those trees tend to fragment memory quite a
|
||||
* lot, increasing cache misses : since they're not "complete", we can't predict the final number of
|
||||
* nodes and we have to allocate nodes on-the-fly. For the same reasons we can't use Opcode's "optimized"
|
||||
* trees here, since they rely on a known layout to perform the "optimization".
|
||||
*
|
||||
* Hybrid trees :
|
||||
*
|
||||
* Hybrid trees try to combine best of both worlds :
|
||||
*
|
||||
* - they use a maximum limit of 16 triangles/leaf. "16" is used so that we'll be able to save the
|
||||
* number of triangles using 4 bits only.
|
||||
*
|
||||
* - they're still "complete" trees thanks to a two-passes building phase. First we create a "vanilla"
|
||||
* AABB-tree with Opcode, limited to 16 triangles/leaf. Then we create a *second* vanilla tree, this
|
||||
* time using the leaves of the first one. The trick is : this second tree is now "complete"... so we
|
||||
* can further transform it into an Opcode's optimized tree.
|
||||
*
|
||||
* - then we run the collision queries on that standard Opcode tree. The only difference is that leaf
|
||||
* nodes contain indices to leaf nodes of another tree. Also, we have to skip all primitive tests in
|
||||
* Opcode optimized trees, since our leaves don't contain triangles anymore.
|
||||
*
|
||||
* - finally, for each collided leaf, we simply loop through 16 triangles max, and collide them with
|
||||
* the bounding volume used in the query (we only support volume-vs-mesh queries here, not mesh-vs-mesh)
|
||||
*
|
||||
* All of that is wrapped in this "hybrid model" that contains the minimal data required for this to work.
|
||||
* It's a mix between old "vanilla" trees, and old "optimized" trees.
|
||||
*
|
||||
* Extra advantages:
|
||||
*
|
||||
* - If we use them for dynamic models, we're left with a very small number of leaf nodes to refit. It
|
||||
* might be a bit faster since we have less nodes to write back.
|
||||
*
|
||||
* - In rigid body simulation, using temporal coherence and sleeping objects greatly reduce the actual
|
||||
* influence of one tree over another (i.e. the speed difference is often invisible). So memory is really
|
||||
* the key element to consider, and in this regard hybrid trees are just better.
|
||||
*
|
||||
* Information to take home:
|
||||
* - they use less ram
|
||||
* - they're not slower (they're faster or slower depending on cases, overall there's no significant
|
||||
* difference *as long as objects don't interpenetrate too much* - in which case Opcode's optimized trees
|
||||
* are still notably faster)

/**
|
||||
* This class is an interface between us and user-defined meshes. Meshes can be defined in a lot of ways, and here we
|
||||
* try to support most of them.
|
||||
*
|
||||
* Basically you have two options:
|
||||
* - callbacks, if OPC_USE_CALLBACKS is defined in OPC_Settings.h.
|
||||
* - else pointers.
|
||||
*
|
||||
* If using pointers, you can also use strides or not. Strides are used when OPC_USE_STRIDE is defined.
|
||||
*
|
||||
*
|
||||
* CALLBACKS:
|
||||
*
|
||||
* Using callbacks is the most generic way to feed OPCODE with your meshes. Indeed, you just have to give
|
||||
* access to three vertices at the end of the day. It's up to you to fetch them from your database, using
|
||||
* whatever method you want. Hence your meshes can lie in system memory or AGP, be indexed or not, use 16
|
||||
* or 32-bits indices, you can decompress them on-the-fly if needed, etc. On the other hand, a callback is
|
||||
* called each time OPCODE needs access to a particular triangle, so there might be a slight overhead.
|
||||
*
|
||||
* To make things clear: geometry & topology are NOT stored in the collision system,
|
||||
* in order to save some ram. So, when the system needs them to perform accurate intersection
|
||||
* tests, you're requested to provide the triangle-vertices corresponding to a given face index.
|
||||
*
|
||||
* Ex:
|
||||
*
|
||||
* \code
|
||||
* static void ColCallback(udword triangle_index, VertexPointers& triangle, udword user_data)
|
||||
* {
|
||||
* // Get back Mesh0 or Mesh1 (you also can use 2 different callbacks)
|
||||
* Mesh* MyMesh = (Mesh*)user_data;
|
||||
* // Get correct triangle in the app-controlled database
|
||||
* const Triangle* Tri = MyMesh->GetTriangle(triangle_index);
|
||||
* // Setup pointers to vertices for the collision system
|
||||
* triangle.Vertex[0] = MyMesh->GetVertex(Tri->mVRef[0]);
|
||||
* triangle.Vertex[1] = MyMesh->GetVertex(Tri->mVRef[1]);
|
||||
* triangle.Vertex[2] = MyMesh->GetVertex(Tri->mVRef[2]);
|
||||
* }
|
||||
*
|
||||
* // Setup callbacks
|
||||
* MeshInterface0->SetCallback(ColCallback, udword(Mesh0));
|
||||
* MeshInterface1->SetCallback(ColCallback, udword(Mesh1));
|
||||
* \endcode
|
||||
*
|
||||
* Of course, you should make this callback as fast as possible. And you're also not supposed
|
||||
* to modify the geometry *after* the collision trees have been built. The alternative was to
|
||||
* store the geometry & topology in the collision system as well (as in RAPID) but we have found
|
||||
* this approach to waste a lot of ram in many cases.
|
||||
*
|
||||
*
|
||||
* POINTERS:
|
||||
*
|
||||
* If you're internally using the following canonical structures:
|
||||
* - a vertex made of three 32-bits floating point values
|
||||
* - a triangle made of three 32-bits integer vertex references
|
||||
* ...then you may want to use pointers instead of callbacks. This is the same, except OPCODE will directly
|
||||
* use provided pointers to access the topology and geometry, without using a callback. It might be faster,
|
||||
* but probably not as safe. Pointers have been introduced in OPCODE 1.2.
|
||||
*
|
||||
* Ex:
|
||||
*
|
||||
* \code
|
||||
* // Setup pointers
|
||||
* MeshInterface0->SetPointers(Mesh0->GetFaces(), Mesh0->GetVerts());
|
||||
* MeshInterface1->SetPointers(Mesh1->GetFaces(), Mesh1->GetVerts());
|
||||
* \endcode
|
||||
*
|
||||
*
|
||||
* STRIDES:
|
||||
*
|
||||
* If your vertices are D3D-like entities interleaving a position, a normal and/or texture coordinates
|
||||
* (i.e. if your vertices are FVFs), you might want to use a vertex stride to skip extra data OPCODE
|
||||
* doesn't need. Using a stride shouldn't be notably slower than not using it, but it might increase
|
||||
* cache misses. Please also note that you *shouldn't* read from AGP or video-memory buffers !
|
||||
*
|
||||
*
|
||||
* In any case, compilation flags are here to select callbacks/pointers/strides at compile time, so
|
||||
* choose what's best for your application. All of this has been wrapped into this MeshInterface.

/**
|
||||
* This class is an interface between us and user-defined meshes. Meshes can be defined in a lot of ways, and here we
|
||||
* try to support most of them.
|
||||
*
|
||||
* Basically you have two options:
|
||||
* - callbacks, if OPC_USE_CALLBACKS is defined in OPC_Settings.h.
|
||||
* - else pointers.
|
||||
*
|
||||
* If using pointers, you can also use strides or not. Strides are used when OPC_USE_STRIDE is defined.
|
||||
*
|
||||
*
|
||||
* CALLBACKS:
|
||||
*
|
||||
* Using callbacks is the most generic way to feed OPCODE with your meshes. Indeed, you just have to give
|
||||
* access to three vertices at the end of the day. It's up to you to fetch them from your database, using
|
||||
* whatever method you want. Hence your meshes can lie in system memory or AGP, be indexed or not, use 16
|
||||
* or 32-bits indices, you can decompress them on-the-fly if needed, etc. On the other hand, a callback is
|
||||
* called each time OPCODE needs access to a particular triangle, so there might be a slight overhead.
|
||||
*
|
||||
* To make things clear: geometry & topology are NOT stored in the collision system,
|
||||
* in order to save some ram. So, when the system needs them to perform accurate intersection
|
||||
* tests, you're requested to provide the triangle-vertices corresponding to a given face index.
|
||||
*
|
||||
* Ex:
|
||||
*
|
||||
* \code
|
||||
* static void ColCallback(udword triangle_index, VertexPointers& triangle, udword user_data)
|
||||
* {
|
||||
* // Get back Mesh0 or Mesh1 (you also can use 2 different callbacks)
|
||||
* Mesh* MyMesh = (Mesh*)user_data;
|
||||
* // Get correct triangle in the app-controlled database
|
||||
* const Triangle* Tri = MyMesh->GetTriangle(triangle_index);
|
||||
* // Setup pointers to vertices for the collision system
|
||||
* triangle.Vertex[0] = MyMesh->GetVertex(Tri->mVRef[0]);
|
||||
* triangle.Vertex[1] = MyMesh->GetVertex(Tri->mVRef[1]);
|
||||
* triangle.Vertex[2] = MyMesh->GetVertex(Tri->mVRef[2]);
|
||||
* }
|
||||
*
|
||||
* // Setup callbacks
|
||||
* MeshInterface0->SetCallback(ColCallback, udword(Mesh0));
|
||||
* MeshInterface1->SetCallback(ColCallback, udword(Mesh1));
|
||||
* \endcode
|
||||
*
|
||||
* Of course, you should make this callback as fast as possible. And you're also not supposed
|
||||
* to modify the geometry *after* the collision trees have been built. The alternative was to
|
||||
* store the geometry & topology in the collision system as well (as in RAPID) but we have found
|
||||
* this approach to waste a lot of ram in many cases.
|
||||
*
|
||||
*
|
||||
* POINTERS:
|
||||
*
|
||||
* If you're internally using the following canonical structures:
|
||||
* - a vertex made of three 32-bits floating point values
|
||||
* - a triangle made of three 32-bits integer vertex references
|
||||
* ...then you may want to use pointers instead of callbacks. This is the same, except OPCODE will directly
|
||||
* use provided pointers to access the topology and geometry, without using a callback. It might be faster,
|
||||
* but probably not as safe. Pointers have been introduced in OPCODE 1.2.
|
||||
*
|
||||
* Ex:
|
||||
*
|
||||
* \code
|
||||
* // Setup pointers
|
||||
* MeshInterface0->SetPointers(Mesh0->GetFaces(), Mesh0->GetVerts());
|
||||
* MeshInterface1->SetPointers(Mesh1->GetFaces(), Mesh1->GetVerts());
|
||||
* \endcode
|
||||
*
|
||||
*
|
||||
* STRIDES:
|
||||
*
|
||||
* If your vertices are D3D-like entities interleaving a position, a normal and/or texture coordinates
|
||||
* (i.e. if your vertices are FVFs), you might want to use a vertex stride to skip extra data OPCODE
|
||||
* doesn't need. Using a stride shouldn't be notably slower than not using it, but it might increase
|
||||
* cache misses. Please also note that you *shouldn't* read from AGP or video-memory buffers !
|
||||
*
|
||||
*
|
||||
* In any case, compilation flags are here to select callbacks/pointers/strides at compile time, so
|
||||
* choose what's best for your application. All of this has been wrapped into this MeshInterface.

/**
|
||||
* The main collision wrapper, for all trees. Supported trees are:
|
||||
* - Normal trees (2*N-1 nodes, full size)
|
||||
* - No-leaf trees (N-1 nodes, full size)
|
||||
* - Quantized trees (2*N-1 nodes, half size)
|
||||
* - Quantized no-leaf trees (N-1 nodes, half size)
|
||||
*
|
||||
* Usage:
|
||||
*
|
||||
* 1) Create a static mesh interface using callbacks or pointers. (see OPC_MeshInterface.cpp).
|
||||
* Keep it around in your app, since a pointer to this interface is saved internally and
|
||||
* used until you release the collision structures.
|
||||
*
|
||||
* 2) Build a Model using a creation structure:
|
||||
*
|
||||
* \code
|
||||
* Model Sample;
|
||||
*
|
||||
* OPCODECREATE OPCC;
|
||||
* OPCC.IMesh = ...;
|
||||
* OPCC.Rules = ...;
|
||||
* OPCC.NoLeaf = ...;
|
||||
* OPCC.Quantized = ...;
|
||||
* OPCC.KeepOriginal = ...;
|
||||
* bool Status = Sample.Build(OPCC);
|
||||
* \endcode
|
||||
*
|
||||
* 3) Create a tree collider and set it up:
|
||||
*
|
||||
* \code
|
||||
* AABBTreeCollider TC;
|
||||
* TC.SetFirstContact(...);
|
||||
* TC.SetFullBoxBoxTest(...);
|
||||
* TC.SetFullPrimBoxTest(...);
|
||||
* TC.SetTemporalCoherence(...);
|
||||
* \endcode
|
||||
*
|
||||
* 4) Perform a collision query
|
||||
*
|
||||
* \code
|
||||
* // Setup cache
|
||||
* static BVTCache ColCache;
|
||||
* ColCache.Model0 = &Model0;
|
||||
* ColCache.Model1 = &Model1;
|
||||
*
|
||||
* // Collision query
|
||||
* bool IsOk = TC.Collide(ColCache, World0, World1);
|
||||
*
|
||||
* // Get collision status => if true, objects overlap
|
||||
* BOOL Status = TC.GetContactStatus();
|
||||
*
|
||||
* // Number of colliding pairs and list of pairs
|
||||
* udword NbPairs = TC.GetNbPairs();
|
||||
* const Pair* p = TC.GetPairs()
|
||||
* \endcode
|
||||
*
|
||||
* 5) Stats
|
||||
*
|
||||
* \code
|
||||
* Model0.GetUsedBytes() = number of bytes used for this collision tree
|
||||
* TC.GetNbBVBVTests() = number of BV-BV overlap tests performed during last query
|
||||
* TC.GetNbPrimPrimTests() = number of Triangle-Triangle overlap tests performed during last query
|
||||
* TC.GetNbBVPrimTests() = number of Triangle-BV overlap tests performed during last query

/**
|
||||
* The main collision wrapper, for all trees. Supported trees are:
|
||||
* - Normal trees (2*N-1 nodes, full size)
|
||||
* - No-leaf trees (N-1 nodes, full size)
|
||||
* - Quantized trees (2*N-1 nodes, half size)
|
||||
* - Quantized no-leaf trees (N-1 nodes, half size)
|
||||
*
|
||||
* Usage:
|
||||
*
|
||||
* 1) Create a static mesh interface using callbacks or pointers. (see OPC_MeshInterface.cpp).
|
||||
* Keep it around in your app, since a pointer to this interface is saved internally and
|
||||
* used until you release the collision structures.
|
||||
*
|
||||
* 2) Build a Model using a creation structure:
|
||||
*
|
||||
* \code
|
||||
* Model Sample;
|
||||
*
|
||||
* OPCODECREATE OPCC;
|
||||
* OPCC.IMesh = ...;
|
||||
* OPCC.Rules = ...;
|
||||
* OPCC.NoLeaf = ...;
|
||||
* OPCC.Quantized = ...;
|
||||
* OPCC.KeepOriginal = ...;
|
||||
* bool Status = Sample.Build(OPCC);
|
||||
* \endcode
|
||||
*
|
||||
* 3) Create a tree collider and set it up:
|
||||
*
|
||||
* \code
|
||||
* AABBTreeCollider TC;
|
||||
* TC.SetFirstContact(...);
|
||||
* TC.SetFullBoxBoxTest(...);
|
||||
* TC.SetFullPrimBoxTest(...);
|
||||
* TC.SetTemporalCoherence(...);
|
||||
* \endcode
|
||||
*
|
||||
* 4) Perform a collision query
|
||||
*
|
||||
* \code
|
||||
* // Setup cache
|
||||
* static BVTCache ColCache;
|
||||
* ColCache.Model0 = &Model0;
|
||||
* ColCache.Model1 = &Model1;
|
||||
*
|
||||
* // Collision query
|
||||
* bool IsOk = TC.Collide(ColCache, World0, World1);
|
||||
*
|
||||
* // Get collision status => if true, objects overlap
|
||||
* BOOL Status = TC.GetContactStatus();
|
||||
*
|
||||
* // Number of colliding pairs and list of pairs
|
||||
* udword NbPairs = TC.GetNbPairs();
|
||||
* const Pair* p = TC.GetPairs()
|
||||
* \endcode
|
||||
*
|
||||
* 5) Stats
|
||||
*
|
||||
* \code
|
||||
* Model0.GetUsedBytes() = number of bytes used for this collision tree
|
||||
* TC.GetNbBVBVTests() = number of BV-BV overlap tests performed during last query
|
||||
* TC.GetNbPrimPrimTests() = number of Triangle-Triangle overlap tests performed during last query
|
||||
* TC.GetNbBVPrimTests() = number of Triangle-BV overlap tests performed during last query
|
||||
* \endcode
|
||||
*
|
||||
* \class Model
