Function Documentation

A3DStatus A3DFaceUVPointInsideManagerCreate(A3DFaceUVPointInsideManagerData const *pData, A3DFaceUVPointInsideManager **pManager)

Creates an A3DFaceUVPointInsideManager from an A3DFaceUVPointInsideManagerData structure.

Version
5.2

Return values:
  • A3D_INVALID_DATA_STRUCT_SIZE –
  • A3D_INVALID_DATA_STRUCT_NULL –
  • A3D_SUCCESS –
Returns:

A3D_SUCCESS on success, or an error code on failure
A3DStatus A3DFaceUVPointInsideManagerDelete(A3DFaceUVPointInsideManager *pManager)

Deletes an A3DFaceUVPointInsideManager.

Version
5.2

Return values:
  • A3D_INVALID_ENTITY_TYPE –
  • A3D_INVALID_DATA_STRUCT_NULL –
  • A3D_SUCCESS –
Returns:

A3D_SUCCESS on success, or an error code on failure
A3DStatus A3DFaceUVPointInside(A3DFaceUVPointInsideManager *pManager, A3DTopoFace const *psFace, A3DVector2dData const *pUVParameter, A3DDouble dTol3D, A3DUns8 *puiUVInFace)

This function projects a UV point on a face, and return if it’s inside or not.

puiUVInFace gives the result: 0 if the point is outside the face, and 1 if it’s inside. dTol3D is used to check if a UV point is on edges. If it’s set to zero and the point is not inside the face but potentially on its edges, the tolerance check will not happen.

Version
5.2

Parameters:
  • pManager – [in] The face manager.
  • psFace – [in] The input face.
  • pUVParameter – [in] The input UV Point.
  • dTol3D – [in] Tolerance to check if the UV point is on the edge.
  • puiUVInFace – [out] Status of the UV point on the face. 0 is outside, 1 is inside.
Return values:
  • A3D_SUCCESS –
  • A3D_INVALID_ENTITY_TYPE –
  • A3D_INVALID_ENTITY_NULL –
  • A3D_TOPO_GEOMETRY_MISSING – - it’s missing UV curves
  • A3D_ERROR –
Returns:

A3D_SUCCESS on success, or an error code on failure
