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

0df8887990 improve pybullet performance of loadURDF/SDF/MJCF and 'createCollisionShape'/'createMultiBody' for GUI/VR/SHARED_MEMORY,
use p.configureDebugVisualizer(p.COV_ENABLE_RENDERING,0) before loading and
p.configureDebugVisualizer(p.COV_ENABLE_RENDERING,1) afterwards

9fef6c1d66 Add C++ version VRGloveSimulatorMain example, using the serial library.
First run the App_PhysicsServer_SharedMemory_VR_vs2010.exe to run the VR server,
then run App_VRGloveHandSimulator. You likely need to tune the minV/maxV for each finger (check values using Arduino IDE Serial Monitor)

0e8bc418d7 add utility for reading and writing of minitaur quadruped robot log files.
Example usage:
const char* fileName = "D:/LOG00053.TXT";
btAlignedObjectArray<MinitaurLogRecord> logRecords;
btAlignedObjectArray<std::string> structNames;
std::string structTypes;
bool verbose = false;
//reading
int val = readMinitaurLogFile(fileName, structNames, structTypes,
logRecords, verbose);

//writing
const char* fileNameOut = "D:/LOG00100.TXT";
FILE* f = createMinitaurLogFile(fileNameOut,structNames,structTypes);
for (int i=0;i<logRecords.size();i++)
{
  appendMinitaurLogData(f, structTypes, logRecords[i]);
}
closeMinitaurLogFile(f);

f0f694145d Implement TimeWarpBase.
-------------------------------------
This commit implements speeding up and slowing down examples. The
example can be influenced by the parameters. A separate example will be
added to show off the capabilities of the TimeWarpBase for other
examples. 

The walkers work quite well, a successful evolution was run over night
and reached a walker distance of 7.2m.

c28cd03fbd OpenVR controller can pick/drag objects. Instructions, Windows only:
Compile using premake+visual studio, and compile App_SharedMemoryPhysics_VR
Compile pybullet using cmake using cmake -DBUILD_PYBULLET=OFF -DCMAKE_BUILD_TYPE=Release ..
Create a symbolic link from c:\python\dlls\pybullet.pyd to C:\develop\bullet3\cmp\lib\Release\pybullet.dll
App_SharedMemoryPhysics_VR
Run Python. Here are some Python lines to get going:
import pybullet as p
p.connect(p.SHARED_MEMORY)
p.loadURDF("cube.urdf")
p.setGravity(0,0,-10)
p.setRealTimeSimulation(1)

Allow real-time simulation in physics server, add pybullet command setRealTimeSimulation to control it
Mesh decimation (reduce number of triangles/vertices) using a Blender modifier for Kuka IIWA and Husky
Disabled the 'glFlush' commands in GLInstancingRenderer.
Add VR controller methods to examples\CommonInterfaces\CommonExampleInterface.h
Use the ANSI version in Windows file/string operations instead of unicode, hope this doesn't break builds.
