Helpers for Representation Items.

Function Documentation

A3DStatus A3DRiComputeMesh(const A3DRiRepresentationItem *pRi, const A3DMiscCascadedAttributes *pAttributes, A3DMeshData *pMesh)

Fill the mesh structure with tessellation information of a previously created A3DRiRepresentationItem with the current graphical context( A3DMiscCascadedAttributes ).

Or release the memory used by the mesh if nullptr is provided instead of the representation item.

Version

24.0

Note

This function computes the mesh for kA3DTypeRiBrepModel and kA3DTypeRiPolyBrepModel representation items only.

Parameters

• pRi – [in] A3DRiRepresentationItem from which we compute the mesh. If nullptr, release the memory of the mesh.

• pAttributes – [in] A3DMiscCascadedAttributes of the representation item’s father.

• pMesh – [inout] A3DMeshData Mesh computed or the mesh to release if pRi = nullptr.

Return values

• A3D_INITIALIZE_NOT_CALLED –

• A3D_INVALID_DATA_STRUCT_SIZE –

• A3D_INVALID_DATA_STRUCT_NULL –

• A3D_INVALID_ENTITY_NULL –

• A3D_INVALID_ENTITY_TYPE –

• A3D_MESH_EMPTY –

• A3D_MESH_INCONSISTENT –

• A3D_ERROR –

• A3D_SUCCESS –

Returns

A3D_SUCCESS in case of success or an error code
