GetConceptualFaceUV2XYZ

This function returns real world coordinates for a specific conceptualFace given its UV coordinates.
The UV coordinates are expected to be both (inclusive) between 0. and 1., i.e. [0..1].

Note: the returned value is the exact location within the 3D model space
according to the internal definition. This can slightly differ from the
generated geometry because of segmentation.

Therefore the following code returns the same values for u and v (if proper values, i.e. both within range [0..1]):
double u = .., v = ..;
double x, y, z;
GetConceptualFaceUV2XYZ(conceptualFace, &x, &y, &z, u, v);
GetConceptualFaceUV2XYZ(conceptualFace, &u, &v, x, y, z);

The following code returns potentially not exactly the same values for x, y, z (if values are from resutling geometry):
double x = .., y = .., z = ..;
double u, v;
GetConceptualFaceUV2XYZ(conceptualFace, &u, &v, x, y, z);
GetConceptualFaceUV2XYZ(conceptualFace, &x, &y, &z, u, v);

Property owlInstance

Size: 64 bit / 8 byte (value)
The handle to the specific instance in the design tree. The instance handle is static within one open model but is most probably different when the same instance is opened in another model. The instance is always exactly of one unique class.

Property index

Size: 64 bit / 8 byte (value)
This is the index (0 based) of the face in the set of conceptual faces available.

Property x

Size: 32 bit / 4 byte (reference)
x Coordinate

Property y

Size: 32 bit / 4 byte (reference)
y Coordinate

Property z

Size: 32 bit / 4 byte (reference)
z Coordinate
