Class TriangleIndexVertexArray

java.lang.Object

com.bulletphysics.collision.shapes.StridingMeshInterface

public class TriangleIndexVertexArray
extends StridingMeshInterface

TriangleIndexVertexArray allows to use multiple meshes, by indexing into existing triangle/index arrays. Additional meshes can be added using addIndexedMesh.

No duplicate is made of the vertex/index data, it only indexes into external vertex/index arrays. So keep those arrays around during the lifetime of this TriangleIndexVertexArray.

getLockedVertexIndexBase

public VertexData getLockedVertexIndexBase(int subpart)

Description copied from class: StridingMeshInterface

Get read and write access to a subpart of a triangle mesh. This subpart has a continuous array of vertices and indices. In this way the mesh can be handled as chunks of memory with striding very similar to OpenGL vertexarray support. Make a call to unLockVertexBase when the read and write access is finished.

Specified by:

getLockedVertexIndexBase in class StridingMeshInterface

getLockedReadOnlyVertexIndexBase

public VertexData getLockedReadOnlyVertexIndexBase(int subpart)

Specified by:

getLockedReadOnlyVertexIndexBase in class StridingMeshInterface

unLockVertexBase

public void unLockVertexBase(int subpart)

unLockVertexBase finishes the access to a subpart of the triangle mesh. Make a call to unLockVertexBase when the read and write access (using getLockedVertexIndexBase) is finished.

Specified by:

unLockVertexBase in class StridingMeshInterface

unLockReadOnlyVertexBase

public void unLockReadOnlyVertexBase(int subpart)

Specified by:

unLockReadOnlyVertexBase in class StridingMeshInterface

getNumSubParts

public int getNumSubParts()

getNumSubParts returns the number of seperate subparts. Each subpart has a continuous array of vertices and indices.

Specified by:

getNumSubParts in class StridingMeshInterface

getIndexedMeshArray

public ObjectArrayList<IndexedMesh> getIndexedMeshArray()

preallocateVertices

public void preallocateVertices(int numverts)

Specified by:

preallocateVertices in class StridingMeshInterface

preallocateIndices

public void preallocateIndices(int numindices)
