Detailed Description

A convex mesh.

Internally represented as a list of convex polygons. The number of polygons is limited to 256.

To avoid duplicating data when you have several instances of a particular mesh positioned differently, you do not use this class to represent a convex object directly. Instead, you create an instance of this mesh via the PxConvexMeshGeometry and PxShape classes.

Creation

To create an instance of this class call PxPhysics::createConvexMesh(), and PxConvexMesh::release() to delete it. This is only possible once you have released all of its PxShape instances.

Member Function Documentation

◆ acquireReference()

virtual PX_PHYSX_COMMON_API void PxConvexMesh::acquireReference ( )
pure virtual

Acquires a counted reference to a convex mesh.

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

◆ getConcreteTypeName()

virtual PX_PHYSX_COMMON_API const char* PxConvexMesh::getConcreteTypeName ( ) const
inlinevirtual

Returns string name of dynamic type.

Returns
Class name of most derived type of this object.

Implements PxBase.

◆ getIndexBuffer()

virtual PX_PHYSX_COMMON_API const PxU8* PxConvexMesh::getIndexBuffer ( ) const
pure virtual

Returns the index buffer.

Returns
Index buffer.

◆ getLocalBounds()

virtual PX_PHYSX_COMMON_API PxBounds3 PxConvexMesh::getLocalBounds ( ) const
pure virtual

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

Returns
local-space bounds

◆ getMassInformation()

virtual PX_PHYSX_COMMON_API void PxConvexMesh::getMassInformation ( PxReal &  mass,
PxMat33 localInertia,
PxVec3 localCenterOfMass 
) const
pure virtual

Returns the mass properties of the mesh assuming unit density.

The following relationship holds between mass and volume:

mass = volume * density

The mass of a unit density mesh is equal to its volume, so this function returns the volume of the mesh.

Similarly, to obtain the localInertia of an identically shaped object with a uniform density of d, simply multiply the localInertia of the unit density mesh by d.

Parameters
[out]massThe mass of the mesh assuming unit density.
[out]localInertiaThe inertia tensor in mesh local space assuming unit density.
[out]localCenterOfMassPosition of center of mass (or centroid) in mesh local space.

◆ getNbPolygons()

virtual PX_PHYSX_COMMON_API PxU32 PxConvexMesh::getNbPolygons ( ) const
pure virtual

Returns the number of polygons.

Returns
Number of polygons.

◆ getNbVertices()

virtual PX_PHYSX_COMMON_API PxU32 PxConvexMesh::getNbVertices ( ) const
pure virtual

Returns the number of vertices.

Returns
Number of vertices.
See also
getVertices()

◆ getPolygonData()

virtual PX_PHYSX_COMMON_API bool PxConvexMesh::getPolygonData ( PxU32  index,
PxHullPolygon data 
) const
pure virtual

Returns the polygon data.

Parameters
[in]indexPolygon index in [0 ; getNbPolygons()[.
[out]dataPolygon data.
Returns
True if success.

getIndexBuffer() getNbPolygons()

◆ getReferenceCount()

virtual PX_PHYSX_COMMON_API PxU32 PxConvexMesh::getReferenceCount ( ) const
pure virtual

Returns the reference count of a convex mesh.

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

Returns
the current reference count.

◆ getVertices()

virtual PX_PHYSX_COMMON_API const PxVec3* PxConvexMesh::getVertices ( ) const
pure virtual

Returns the vertices.

Returns
Array of vertices.
See also
getNbVertices()

◆ isGpuCompatible()

virtual PX_PHYSX_COMMON_API bool PxConvexMesh::isGpuCompatible ( ) const
pure virtual

This method decides whether a convex mesh is gpu compatible. If the total number of vertices are more than 64 or any number of vertices in a polygon is more than 32, or convex hull data was not cooked with GPU data enabled during cooking or was loaded from a serialized collection, the convex hull is incompatible with GPU collision detection. Otherwise it is compatible.

Returns
True if the convex hull is gpu compatible

◆ isKindOf()

virtual PX_PHYSX_COMMON_API bool PxConvexMesh::isKindOf ( const char *  superClass) const
inlineprotectedvirtual

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

Reimplemented from PxBase.

References PxBase::isKindOf().

◆ release()

virtual PX_PHYSX_COMMON_API void PxConvexMesh::release ( )
pure virtual

Decrements the reference count of a convex mesh and releases it if the new reference count is zero.
