Acquires a counted reference to a triangle mesh.

This method increases the reference count of the triangle mesh by 1. Decrement the reference count by calling release()

Returns the local-space (vertex space) AABB from the triangle mesh.

Returns:

local-space bounds

Returns the number of triangles.

Returns:

number of triangles

See also:

getTriangles() getTrianglesRemap()

Returns the number of vertices.

Returns:

number of vertices

See also:

getVertices()

Returns the reference count for shared meshes.

At creation, the reference count of the mesh is 1. Every shape referencing this mesh increments the count by 1. When the reference count reaches 0, and only then, the mesh gets destroyed automatically.

Returns:

the current reference count.

Returns material table index of given triangle.

This function takes a post cooking triangle index.

Parameters:

[in]

triangleIndex

(internal) index of desired triangle

Returns:

Material table index, or 0xffff if no per-triangle materials are used

Reads the PxTriangleMesh flags.

See the list of flags PxTriangleMeshFlag

Returns:

The values of the PxTriangleMesh flags.

PxTriangleMesh

Returns the triangle indices.

The indices can be 16 or 32bit depending on the number of triangles in the mesh. Call getTriangleMeshFlags() to know if the indices are 16 or 32 bits.

The number of indices is the number of triangles * 3.

Returns:

array of triangles

getNbTriangles() getTriangleMeshFlags() getTrianglesRemap()

Returns the triangle remapping table.

The triangles are internally sorted according to various criteria. Hence the internal triangle order does not always match the original (user-defined) order. The remapping table helps finding the old indices knowing the new ones:

remapTable[ internalTriangleIndex ] = originalTriangleIndex

Returns:

the remapping table (or NULL if 'PxCookingParamssuppressTriangleMeshRemapTable' has been used)

Returns the vertices.

Returns:

array of vertices

See also:

getNbVertices()

Returns all mesh vertices for modification.

This function will return the vertices of the mesh so that their positions can be changed in place. After modifying the vertices you must call refitBVH for the refitting to actually take place. This function maintains the old mesh topology (triangle indices).

Returns:

inplace vertex coordinates for each existing mesh vertex.

Note:

works only for PxMeshMidPhase::eBVH33

Size of array returned is equal to the number returned by getNbVertices().

This function operates on cooked vertex indices.

This means the index mapping and vertex count can be different from what was provided as an input to the cooking routine.

To achieve unchanged 1-to-1 index mapping with orignal mesh data (before cooking) please use the following cooking flags:

eWELD_VERTICES = 0, eDISABLE_CLEAN_MESH = 1.

It is also recommended to make sure that a call to validateTriangleMesh returns true if mesh cleaning is disabled.

refitBVH()

Returns whether a given type name matches with the type of this instance.

Reimplemented from PxBase.

Reimplemented in PxBVH33TriangleMesh, and PxBVH34TriangleMesh.

Refits BVH for mesh vertices.

This function will refit the mesh BVH to correctly enclose the new positions updated by getVerticesForModification. Mesh BVH will not be reoptimized by this function so significantly different new positions will cause significantly reduced performance.

Returns:

New bounds for the entire mesh.

Note:

works only for PxMeshMidPhase::eBVH33

PhysX does not keep a mapping from the mesh to mesh shapes that reference it.

Call PxShape::setGeometry on each shape which references the mesh, to ensure that internal data structures are updated to reflect the new geometry.

PxShape::setGeometry does not guarantee correct/continuous behavior when objects are resting on top of old or new geometry.

It is also recommended to make sure that a call to validateTriangleMesh returns true if mesh cleaning is disabled.

Active edges information will be lost during refit, the rigid body mesh contact generation might not perform as expected.
