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.

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

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)

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

c5164e503f fix in structure alignment of btMultiBodyLinkDoubleData and btMultiBodyDoubleData 
causing serialization issue in  URDF/SDF loading in double-precision mode on Windows 32bit.
(it was fine on Mac/Linux 64bit)
bump serialization version to 2.85, as we change the file format
fix in name clash in makesdna.cpp -> intptr_t is already defined.

60d2b99151 Physics runs in a separate thread from rendering in PhysicsServerExample (preliminary) 
Improve rendering performance. OpenVR experience is smooth now.
commit needs a bit more testing before pushing in main repo.

2fc0358750 Expose a better API to allow any render engine to be used for the physics simulation when loading URDF/SDF files. 
See bullet3/examples/Importers/ImportURDFDemo/DefaultVisualShapeConverter.h
Give the kuka_iiwa/model.urdf some blue color, not just orange, to mimick the original a bit better
Preparation for the CMD_CAMERA_IMAGE_COMPLETED command, to expose a virtual camera to the robotics API

081a40d254 initial implementation to send debug lines from physics server to client, 
need to add streaming because memory is too small to store all lines

e7bafbc71c make Bullet URDF parser more similar to the ROS URDF parser. There is still a difference in ordering of links, 
due to the use of different hash-map implementations, with a difference in iterator order
(btHashMap versus std::hashmap)
