Class PxTriangleMeshDesc

java.lang.Object
physx.NativeObject
physx.geometry.PxSimpleTriangleMesh
physx.cooking.PxTriangleMeshDesc
public class PxTriangleMeshDesc extends PxSimpleTriangleMesh
Descriptor class for #PxTriangleMesh.

Note that this class is derived from PxSimpleTriangleMesh which contains the members that describe the basic mesh. The mesh data is *copied* when an PxTriangleMesh object is created from this descriptor. After the call the user may discard the triangle data.

      public static PxTriangleMeshDesc createAt(long address)
      Parameters:
      address - Pre-allocated memory, where the object is created.
      Returns:
      Stack allocated object of PxTriangleMeshDesc

    • createAt

      public static <T> PxTriangleMeshDesc createAt(T allocator, NativeObject.Allocator<T> allocate)
      Type Parameters:
      T - Allocator class, e.g. LWJGL's MemoryStack.
      Parameters:
      allocator - Object to use for allocation, e.g. an instance of LWJGL's MemoryStack.
      allocate - Method to call on allocator to obtain the target address, e.g. MemoryStack::nmalloc.
      Returns:
      Stack allocated object of PxTriangleMeshDesc

    • destroy

      public void destroy()
      Overrides:
      destroy in class PxSimpleTriangleMesh

    • getMaterialIndices

      public PxTypedStridedData_PxU16Const getMaterialIndices()
      Optional pointer to first material index, or NULL. There are PxSimpleTriangleMesh::numTriangles indices in total. Caller may add materialIndexStride bytes to the pointer to access the next triangle.

      When a triangle mesh collides with another object, a material is required at the collision point. If materialIndices is NULL, then the material of the PxShape instance is used. Otherwise, if the point of contact is on a triangle with index i, then the material index is determined as: PxMaterialTableIndex index = *(PxMaterialTableIndex *)(((PxU8*)materialIndices) + materialIndexStride * i);

      If the contact point falls on a vertex or an edge, a triangle adjacent to the vertex or edge is selected, and its index used to look up a material. The selection is arbitrary but consistent over time.

      Default: NULL

    • setMaterialIndices

      public void setMaterialIndices(PxTypedStridedData_PxU16Const value)
      Optional pointer to first material index, or NULL. There are PxSimpleTriangleMesh::numTriangles indices in total. Caller may add materialIndexStride bytes to the pointer to access the next triangle.

      When a triangle mesh collides with another object, a material is required at the collision point. If materialIndices is NULL, then the material of the PxShape instance is used. Otherwise, if the point of contact is on a triangle with index i, then the material index is determined as: PxMaterialTableIndex index = *(PxMaterialTableIndex *)(((PxU8*)materialIndices) + materialIndexStride * i);

      If the contact point falls on a vertex or an edge, a triangle adjacent to the vertex or edge is selected, and its index used to look up a material. The selection is arbitrary but consistent over time.

      Default: NULL
