RETURN TYPEvoid

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Loads a mesh from a file.

The function loads mesh from the specified file and returns it. If the mesh cannot be read, throws an error Vertex attributes (i.e. space and texture coodinates, normals and colors) are returned in same-sized arrays with corresponding elements having the same indices. This means that if a face uses a vertex with a normal or a texture coordinate with different indices (which is typical for OBJ files for example), this vertex will be duplicated for each face it uses.

Currently, the following file formats are supported:

• Wavefront obj file *.obj (ONLY TRIANGULATED FACES)
• Polygon File Format *.ply

filename

Name of the file

vertices

Output destination, filled by the native operation. vertex coordinates, each value contains 3 floats

indices

Output destination, filled by the native operation. per-face list of vertices, each value is a vector of ints

normals

Output destination, filled by the native operation. per-vertex normals, each value contains 3 floats

colors

Output destination, filled by the native operation. per-vertex colors, each value contains 3 floats

texCoords

Output destination, filled by the native operation. per-vertex texture coordinates, each value contains 2 or 3 floats
