public class btTriangleMesh
extends btTriangleIndexVertexArray

The btTriangleMesh class is a convenience class derived from btTriangleIndexVertexArray, that provides storage for a concave triangle mesh. It can be used as data for the btBvhTriangleMeshShape. It allows either 32bit or 16bit indices, and 4 (x-y-z-w) or 3 (x-y-z) component vertices. If you want to share triangle/index data between graphics mesh and collision mesh (btBvhTriangleMeshShape), you can directly use btTriangleIndexVertexArray or derive your own class from btStridingMeshInterface. Performance of btTriangleMesh and btTriangleIndexVertexArray used in a btBvhTriangleMeshShape is the same.

Constructor Detail

btTriangleMesh

public btTriangleMesh(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

btTriangleMesh

public btTriangleMesh(long size)

Native array allocator. Access with Pointer.position(long).

btTriangleMesh

public btTriangleMesh(@Cast(value="bool")
                      boolean use32bitIndices,
                      @Cast(value="bool")
                      boolean use4componentVertices)

btTriangleMesh

public btTriangleMesh()

Method Detail

position

public btTriangleMesh position(long position)

Overrides:

position in class btTriangleIndexVertexArray

getPointer

public btTriangleMesh getPointer(long i)

Overrides:

getPointer in class btTriangleIndexVertexArray

m_weldingThreshold

@Cast(value="btScalar")
public double m_weldingThreshold()

m_weldingThreshold

public btTriangleMesh m_weldingThreshold(double setter)

getUse32bitIndices

@Cast(value="bool")
public boolean getUse32bitIndices()

getUse4componentVertices

@Cast(value="bool")
public boolean getUse4componentVertices()

addTriangle

public void addTriangle(@Const @ByRef
                        btVector3 vertex0,
                        @Const @ByRef
                        btVector3 vertex1,
                        @Const @ByRef
                        btVector3 vertex2,
                        @Cast(value="bool")
                        boolean removeDuplicateVertices)

By default addTriangle won't search for duplicate vertices, because the search is very slow for large triangle meshes. In general it is better to directly use btTriangleIndexVertexArray instead.

addTriangle

public void addTriangle(@Const @ByRef
                        btVector3 vertex0,
                        @Const @ByRef
                        btVector3 vertex1,
                        @Const @ByRef
                        btVector3 vertex2)

addTriangleIndices

public void addTriangleIndices(int index1,
                               int index2,
                               int index3)

Add a triangle using its indices. Make sure the indices are pointing within the vertices array, so add the vertices first (and to be sure, avoid removal of duplicate vertices)

getNumTriangles

public int getNumTriangles()

preallocateVertices

public void preallocateVertices(int numverts)

Overrides:

preallocateVertices in class btTriangleIndexVertexArray

preallocateIndices

public void preallocateIndices(int numindices)

Overrides:

preallocateIndices in class btTriangleIndexVertexArray

findOrAddVertex

public int findOrAddVertex(@Const @ByRef
                           btVector3 vertex,
                           @Cast(value="bool")
                           boolean removeDuplicateVertices)

findOrAddVertex is an internal method, use addTriangle instead

addIndex

public void addIndex(int index)

addIndex is an internal method, use addTriangle instead
