UvVertT

Object of this class represents a single UV vertex in a UV map.

Fields

IdxT m_ControlId
An integer value which is internally ignored by the packer, so the application may initialize it according to its needs. In particular this field might be used when building m_pVertArray in order to distinguish two UV vertices which have the same UV coordinates, but correspond to two different 3D vertices. Check the Sample application code for a usage example - it initializes the m_ControlId field with an index of the corresponding 3d vertex in order to avoid duplicated vertices in a UV face.

Vector2T m_UvCoords
UV coordinates of the given UV vertex. This field must always be initialized by the application.

Vector3T m_Vert3dCoords
3d coordinates of the 3d vertex corresponding to the given UV vertex. Currently this field is only used when m_NormalizeIslands parameter is set to true. Otherwise it is ignored by the packer, hence it doesn’t have to be initialized by the application.
