b257bd731b PyBullet: allow createVisualShape to pass vertices, indices, normals and uv coordinates. This can be combined with changeVisualShape to set the texture. 2019-01-29 12:03:11 -08:00

a44df2b0a6 PyBullet: allow to pass vertices (for convex) and vertices+indices (for concave) to createCollisionShape
See createObstacleCourse.py for an example use. At the moment a limit of 1024 vertices and 1024 indices.
Will be lifted once we implement the streaming version (soon).

dba239fe8d First pass of load files through an interface (to allow loading from memory, zip file etc). So instead of posix fopen/fread, using CommonFileIOInterface.
A fileIO plugin can override custom file IO operations. As a small test, load files from a zipfile in memory.
Default fileIO implementation is in examples/Utils/b3BulletDefaultFileIO.h
Affects URDF, SDF, MJCF, Wavefront OBJ, STL, DAE, images.

f79b04357f Update URDF Importer to process sensor elements.
Update the URDF Importer to add sensors as 0 mass 0 inertia elements
attached by a fixed joint. This way their states can be read as links.

ab8f16961e Code-style consistency improvement:
Apply clang-format-all.sh using the _clang-format file through all the cpp/.h files.
make sure not to apply it to certain serialization structures, since some parser expects the * as part of the name, instead of type.
This commit contains no other changes aside from adding and applying clang-format-all.sh

552cb5852a PyBullet: add signed distance field support, with example/signedDistanceField.py
See also data\toys\concave_box.urdf and data\toys\concave_box.cdf

data\toys\concave_box.cdf was generated from concave_box.obj using
//GenerateSDF.exe -r "32 32 32" -d "-1.6 -1.6 -.6 1.6 1.6 .6" concave_box.obj
//SDF is based on code from DiscreGrid, https://github.com/InteractiveComputerGraphics/Discregrid

329a1f5a74 PyBullet: move TinyRenderer into a plugin, default statically loaded. You can also dynamically load a render plugin, as shown in renderPlugin.py example. premake has a way to compile the tinyRendererPlugin. 2018-01-17 12:48:48 -08:00

aafaa7e33e Expose optional "globalScaling" factor to pybullet.loadURDF and pybullet.loadSDF. This will scale the visual, collision shapes and transform locations.
Fix two_cubes.sdf (was lacking collision shape for second cube)

af6bf8ddc8 plumb URDF/SDF audio_source into PhysicsServerCommandProcessor, allow to play sounds on collision !
See also https://youtu.be/eppOjTfx5Jg for a first test, and this modified URDF how to add sounds:
https://github.com/bulletphysics/bullet3/blob/master/data/plane_with_collision_audio.urdf
Add the --audio flag to enable sound in pybullet/Bullet-C-API

76dcf3a751 remove the contype=0 in inverted_pendulum.xml, so we can 'mouse-pick' the pendulum.

fdd517e00f First step towards a MuJoCo MJCF importer for Bullet. It can load the humanoid.xml, ant.xml and some other OpenAI GYM asset files. Not all fields are converted, so it is work-in-progress. This is useful for Reinforcement Learning experiments, and would also help integration with DeepMind Lab. 2016-12-30 18:32:57 -08:00
