gDPSetTexturePersp
Format#include "gbi.h" gDPSetTexturePersp(Gfx *gdl, unsigned int enable) gsDPSetTexturePersp(unsigned int enable)Arguments
- gdl is the pointer to the graphics display list
- enable sets texture-perspective correction off or on (G_TP_NONE or G_TP_PERSP)
It enables or disables texture-perspective correction. The RDP corrects the texture coordinate at each pixel.
Note
Because of assumptions made by the RSP, perspective correction is required for all textured triangles (including those drawn with an orthographic projection).
When drawing texture rectangles (sprites), you should always disable perspective correction.
