Description

This function is for setting the TEV swap table. The swap table makes it possible to swap at the component level the rasterized color inputs and the texture color inputs in the TEV stage. The defaults for the swap table are as follows.

Entry Red component Green component Blue component Alpha Component Swap result
GX_TEV_SWAP0 GX_CH_RED GX_CH_GREEN GX_CH_BLUE GX_CH_ALPHA RGBA
GX_TEV_SWAP1 GX_CH_RED GX_CH_RED GX_CH_RED GX_CH_ALPHA RRRA
GX_TEV_SWAP2 GX_CH_GREEN GX_CH_GREEN GX_CH_GREEN GX_CH_ALPHA GGGA
GX_TEV_SWAP3 GX_CH_BLUE GX_CH_BLUE GX_CH_BLUE GX_CH_ALPHA BBBA

The table specifies for a single entry how an input color component is mapped to an output color component.
