Erwin Coumans 87605ca4c8 revert linkNames in createMultiBody, we cannot pass pointers pointing to local memory (storing the string) around into shared memory or over the network. 2021-09-20 12:22:30 -07:00
yycho0108 c0d9553d65 add link names args to CreateMultibody 2021-01-20 15:53:24 +09:00
Erwin Coumans 1e8f39b492 improve premake4 build in case X11 headers are missing 
improve video_sync_mp4.py example
allow to create a heightfield from file or programmatically in C++ robotics api. Example:

{
		b3RobotSimulatorCreateCollisionShapeArgs shapeArgs;
		shapeArgs.m_shapeType = GEOM_HEIGHTFIELD;
		bool useFile = true;
		if (useFile)
		{
			shapeArgs.m_fileName = "D:/dev/bullet3/data/heightmaps/gimp_overlay_out.png";
			shapeArgs.m_meshScale.setValue(.05, .05, 1);
		}
		else
		{
			shapeArgs.m_numHeightfieldColumns = 256;
			shapeArgs.m_numHeightfieldRows = 256;
			shapeArgs.m_meshScale.setValue(.05, .05, 1);
			shapeArgs.m_heightfieldData.resize(shapeArgs.m_numHeightfieldRows * shapeArgs.m_numHeightfieldColumns);
			double heightPerturbationRange = 0.05;
			for (int j = 0; j<int(shapeArgs.m_numHeightfieldColumns / 2); j++)
			{
				for (int i = 0; i < (int(shapeArgs.m_numHeightfieldRows / 2)); i++)
				{
					double height = ((double)rand() / (RAND_MAX)) * heightPerturbationRange;
					shapeArgs.m_heightfieldData[2 * i + 2 * j * shapeArgs.m_numHeightfieldRows] = height;
					shapeArgs.m_heightfieldData[2 * i + 1 + 2 * j * shapeArgs.m_numHeightfieldRows] = height;
					shapeArgs.m_heightfieldData[2 * i + (2 * j + 1) * shapeArgs.m_numHeightfieldRows] = height;
					shapeArgs.m_heightfieldData[2 * i + 1 + (2 * j + 1) * shapeArgs.m_numHeightfieldRows] = height;
				}
			}
		}
		int shape = sim->createCollisionShape(shapeArgs.m_shapeType, shapeArgs);
		b3RobotSimulatorCreateMultiBodyArgs bodyArgs;
		bodyArgs.m_baseCollisionShapeIndex = shape;
		int groundId = sim->createMultiBody(bodyArgs);
		int texId = sim->loadTexture(shapeArgs.m_fileName);
		b3RobotSimulatorChangeVisualShapeArgs args;
		args.m_objectUniqueId = groundId;
		args.m_linkIndex = -1;
		args.m_textureUniqueId = texId;
		sim->changeVisualShape(args);

erwincoumans 85ee4c2934 allow batch creation of objects through PyBullet.createMultiBody, see createMultiBodyBatch.py example. 
expose minGraphicsUpdateTimeMs through PyBullet.connect(p.GUI, options="minGraphicsUpdateTimeMs=32000"), by default OpenGL rendering runs at 4000microseconds intervals.
allow a maximum of 128k objects
fix meshScale for PyBullet.createCollisionShape for custom mesh
expose Pybullet.setPhysicsEngineParameter(minimumSolverIslandSize=...), larger minimum batches group solver constraints together in the same island, to reduce calling overhead (even if they are not related)

Erwin Coumans 2d224cf319 revert backward compabitility in API 2018-10-20 19:44:39 -07:00
erwincoumans ed49edc1af PyBullet change API (since it was broken): pybullet_changeVisualShape with textureUniqueId ==-1 will clear the texture 
b3InitUpdateVisualShape doesn't take textureUniqueId by default. new API b3UpdateVisualShapeTexture to change texture (-1 will clear texture)
PyBullet/BulletRobotics: allow to reset the textureUniqueId to -1, to clear a texture
PyBullet/BulletRobotics: save all texture handles

erwincoumans 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
