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.

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 in case of success or an error code
