Arguments

context

An OC context returned by a successful PEXCreateOCC call.

tm_coord_data

A pointer to parameterization data for this primitive. (See Description in PEXOCCTMCoordFillAreaSet).

facet_attributes (OCC)

A mask indicating the facet attributes provided (PEXGANone, PEXGAColor, PEXGANormal or PEXGAFloatData).

surface_vertex_attributes (OCC)

A mask indicating the vertex attributes provided (PEXGANone, PEXGAColor, PEXGANormal, PEXGA2D or PEXGAFloatData).

edge_attributes (OCC)

A mask indicating the edge attributes provided (PEXGANone, PEXGAEdges).

color_type (OCC)

facet_fp_data_count (OCC)

The number of optional floating-point numbers for each facet.

surface_vertex_fp_data_count (OCC)

The number of floating-point data values defined with each vertex.

all_independent

True if vertices are a simple list.

num_facets

Number of facets.

facet_data

A pointer to the facet data. See Data Formats.

num_verts

The number of vertices.

vertices

A pointer to the vertex data. See Data Formats.

per_edge_data

Optional edge data.

connectivity

A pointer to the list of triangle connectivity data.

data_model (OCC)

Specifies the data model used to represent the geometric data.

data_model_specs (OCC)

Offset and size data for the PEXDataStride or PEXDataUnpacked data models.

Returns

<Same as for PEXOCCTMCoordFillAreaSet.>

Description

Invoke PEXOCCTMCoordIndexedTriangles to compute a projection of texture coordinates onto the indexed triangles and store them in the specified vertex data fields.
