Method Detail

newBuilder

public static R2MeshTangentsBuilderType newBuilder(long v_count,
                                                   long t_count)

Parameters:

v_count - A hint to the implementation regarding the number of vertices that are expected to be created. The implementation will allocate v_count vertices ahead of time to avoid having to perform any internal reallocations during building.

t_count - A hint to the implementation regarding the number of triangles that are expected to be created. The implementation will allocate t_count triangles ahead of time to avoid having to perform any internal reallocations during building.

Returns:

A new mutable mesh builder

generateTangents
