Overview

These two macros are used to set the RwCameraVertex texture coordinates together with those of an RwIm2DVertex.

As both vertex types are frequently worked on together, using these macros can save some typing. They are defined as follows:

Warning:

Do not use these macros on platforms with hardware-accelerated transform and lighting stages.

#define RwIm2DCameraVertexSetU(devvert, camvert, camu, recipz)  \
    MACRO_START                                                 \
    {                                                           \
        RwCameraVertexSetU(camvert, camu);                      \
        RwIm2DVertexSetU(devvert, camu, recipz);                \
