CD Test Framework
=================
This is a very small app used to test various collision detection (CD) algorithms.
It will be first used as a demo/sample for Opcode 1.3 (a lot of people requested this),
and then I will also include benchmarks against competing libraries (Bullet, GIMPACT, etc).
Update April 2, 2008
Erwin Coumans added Bullet support for broadphase test (SAP, MultiSAP, other tests follow)
This CDTestFramework is now included in Bullet/Extras under the ZLib license.
Current version includes tests for:
- sphere vs mesh queries
- OBB vs mesh queries
- capsule vs mesh queries
- complete box pruning
- bipartite box pruning

//there are 6 cases with a single face and and a 4-vertex outline, and
//20 cases with 2 or 3 faces and a 6-vertex outline. a value of 0 indicates
//an invalid case.
// Original list was made of 7 items, I added an 8th element:
// - to padd on a cache line
// - to repeat the first entry to avoid modulos

//the eyepoint with respect to the 6 defining planes of the bbox (2^6=64)
//only 26 (3^3-1, where 1 is "inside" cube) of these cases are valid.
//the first 6 numbers in each row are the indices of the bbox vertices that
//form the outline of which we want to compute the area (counterclockwise
//ordering), the 7th entry means the number of vertices in the outline.
//there are 6 cases with a single face and and a 4-vertex outline, and
//20 cases with 2 or 3 faces and a 6-vertex outline. a value of 0 indicates
//an invalid case.
// Original list was made of 7 items, I added an 8th element:
// - to padd on a cache line
// - to repeat the first entry to avoid modulos
//

// operands are signed, so there is a potential portability problem. Additionally, one might think
// that a shift by any number greater than or equal to WORDBITS would have the same effect, but many

Also, I'd say that you can make more intelligent and interesting filters than this, for example filters

//! Extra comments by Kenny Hoff:
//! Determines the byte-ordering of the current machine (little or big endian)
//! by setting an integer value to 1 (so least significant bit is now 1); take
//! the address of the int and cast to a byte pointer (treat integer as an
//! array of four bytes); check the value of the first byte (must be 0 or 1).
//! If the value is 1, then the first byte least significant byte and this
//! implies LITTLE endian. If the value is 0, the first byte is the most
//! significant byte, BIG endian. Examples:
//! integer 1 on BIG endian: 00000000 00000000 00000000 00000001
//! integer 1 on LITTLE endian: 00000001 00000000 00000000 00000000
//!---------------------------------------------------------------------------
//! int IsLittleEndian() { int x=1; return ( ((char*)(&x))[0] ); }
inline_ char LittleEndian() { int i = 1; return *((char*)&i); }

inline_ udword LowestOneBit(udword w) { return ((w) & (~(w)+1)); }
// inline_ udword LowestOneBit_(udword w) { return ((w) & (-(w))); }
// Most Significant 1 Bit
// Given a binary integer value x, the most significant 1 bit (highest numbered element of a bit set)
// can be computed using a SWAR algorithm that recursively "folds" the upper bits into the lower bits.
// This process yields a bit vector with the same most significant 1 as x, but all 1's below it.
// Bitwise AND of the original value with the complement of the "folded" value shifted down by one
// yields the most significant bit. For a 32-bit value:

"Just call it repeatedly with various input values and always with the same variable as "memory".
The sharpness determines the degree of filtering, where 0 completely filters out the input, and 1
does no filtering at all.
I seem to recall from college that this is called an IIR (Infinite Impulse Response) filter. As opposed
to the more typical FIR (Finite Impulse Response).
Also, I'd say that you can make more intelligent and interesting filters than this, for example filters
that remove wrong responses from the mouse because it's being moved too fast. You'd want such a filter
to be applied before this one, of course."
