Class PxTriangleMeshGeometry

java.lang.Object

physx.NativeObject

physx.geometry.PxGeometry

physx.geometry.PxTriangleMeshGeometry

public class PxTriangleMeshGeometry
extends PxGeometry

Triangle mesh geometry class.

This class unifies a mesh object with a scaling transform, and lets the combined object be used anywhere a PxGeometry is needed.

The scaling is a transform along arbitrary axes contained in the scale object. The vertices of the mesh in geometry (or shape) space is the PxMeshScale::toMat33() transform, multiplied by the vertex space vertices in the PxTriangleMeshGeometry object.

protected PxTriangleMeshGeometry(long address)

PxTriangleMeshGeometry

public PxTriangleMeshGeometry(PxTriangleMesh mesh)

Constructor. By default creates an empty object with a NULL mesh and identity scale.

Parameters:

mesh - Mesh pointer. May be NULL, though this will not make the object valid for shape construction.

public PxTriangleMeshGeometry(PxTriangleMesh mesh,
 PxMeshScale scaling)

Constructor. By default creates an empty object with a NULL mesh and identity scale.

Parameters:

mesh - Mesh pointer. May be NULL, though this will not make the object valid for shape construction.

scaling - Scale factor.

destroy

public void destroy()

Overrides:

destroy in class PxGeometry

getScale

public PxMeshScale getScale()

The scaling transformation.

setScale

public void setScale(PxMeshScale value)

The scaling transformation.

getMeshFlags

public PxMeshGeometryFlags getMeshFlags()

Mesh flags.

setMeshFlags

public void setMeshFlags(PxMeshGeometryFlags value)

Mesh flags.

getTriangleMesh

public PxTriangleMesh getTriangleMesh()

A reference to the mesh object.

setTriangleMesh

public void setTriangleMesh(PxTriangleMesh value)

A reference to the mesh object.

isValid

public boolean isValid()

Returns true if the geometry is valid.

Returns:

True if the current settings are valid for shape creation.

Note: A valid triangle mesh has a positive scale value in each direction (scale.scale.x > 0, scale.scale.y > 0, scale.scale.z > 0). It is illegal to call PxRigidActor::createShape and PxPhysics::createShape with a triangle mesh that has zero extents in any direction.
