1) Compile the raw shader files to SPIRV:
|
||
|
|
|
||
|
|
glslc -o vertex.spv -c shader.vert
|
||
|
|
glslc -o fragment.spv -c shader.frag
|
||
|
|
|
||
|
|
|
||
|
|
2) Build SDL_shadercross (https://github.com/libsdl-org/SDL_shadercross)
|
||
|
|
|
||
|
|
|
||
|
|
3-A) Compiling for the Vulkan Driver:
|
||
|
|
|
||
|
|
Nothing to do, you just need the previous vertex.spv/fragment.spv, proceed to step 4
|
||
|
|
|
||
|
|
|
||
|
|
3-B) Compiling for the DirectX 12 Driver:
|
||
|
|
|
||
|
|
./shadercross vertex.spv -s SPIRV -d DXBC -t vertex -e main -o vertex.dxbc
|
||
|
|
./shadercross fragment.spv -s SPIRV -d DXBC -t fragment -e main -o fragment.dxbc
|
||
|
|
|
||
|
|
Proceed to step 4
|
||
|
|
|
||
|
|
|
||
|
|
3-C) Compiling for Metal (On windows you'll need the Metal Developer Tools for Windows, on linux you might use wine, but I never tested it):
|
||
|
|
|
||
|
|
./shadercross vertex.spv -s SPIRV -d MSL -t vertex -e main -o vertex.metal
|
||
|
|
./shadercross fragment.spv -s SPIRV -d MSL -t fragment -e main -o fragment.metal
|
||
|
|
|
||
|
|
xcrun -sdk macosx metal -o vertex.ir -c vertex.metal
|
||
|
|
xcrun -sdk macosx metal -o fragment.ir -c fragment.metal
|
||
|
|
xcrun -sdk macosx metallib -o vertex.metallib -c vertex.ir
|
||
|
|
xcrun -sdk macosx metallib -o fragment.metallib -c fragment.ir
|
||
|
|
|
||
|
|
Proceed to step 4
|
||
|
|
|
||
|
|
|
||
|
|
4) Either find a way to load the shader bytecode from file, or use a tool like https://notisrac.github.io/FileToCArray/ to convert the file to a uint8_t array
