nCine::RHI::PICA namespace

Nintendo 3DS fixed-function PICA200 backend on top of citro3d, selected by WITH_RHI_PICA.

The GPU's one programmable stage is its vertex shader, which here is a passthrough of screen-space vertices the CPU has transformed, so like nCine::RHI::GX it has render targets but no programmable fragment stage and consumes nCine::RHI::FixedFunctionPass, translated into texture-combiner and blending setups. Textures live 8x8-tiled in the linear heap and the GPU samples them bottom-up, which the texture stores are written for.

Namespaces

namespace UniformTypeInfo
