Class PxConvexMesh

physx.NativeObject

physx.geometry.PxConvexMesh
public class PxConvexMesh extends PxRefCounted
A convex mesh.

Internally represented as a list of convex polygons. The number of polygons is limited to 256.

To avoid duplicating data when you have several instances of a particular mesh positioned differently, you do not use this class to represent a convex object directly. Instead, you create an instance of this mesh via the PxConvexMeshGeometry and PxShape classes.

Creation

To create an instance of this class call PxPhysics::createConvexMesh(), and PxConvexMesh::release() to delete it. This is only possible once you have released all of its #PxShape instances.

    • isGpuCompatible

      public boolean isGpuCompatible()
      This method decides whether a convex mesh is gpu compatible. If the total number of vertices are more than 64 or any number of vertices in a polygon is more than 32, or convex hull data was not cooked with GPU data enabled during cooking or was loaded from a serialized collection, the convex hull is incompatible with GPU collision detection. Otherwise it is compatible.
      Returns:
      True if the convex hull is gpu compatible
