Shader Cross-Compiler

#include <shcc/shcc.hpp>

Purpose

The Shader Cross-Compilater library is resposible for handling the loading, compiling, translating, and analysis of shaders. Because the Rotary aims to support multiple graphics APIs, multiple shader formats will be needed as well.

Pipeline

Usage

void callback(const std::string& message);
std::string source; // HLSL source

// ...

std::shared_ptr<shcc::Runtime> runtime = shcc::runtime(callback);

shcc::Package package = runtime->package(source, { shcc::Stage::Vertex, shcc::Stage::Fragment });

std::vector<uint8_t> vertexSpvBinary = package.compile(shcc::Stage:Vertex, shcc::Language::Spirv);
std::span<uint32_t> binary(reinterpret_cast<const uint32_t*>(vertexSpvBinary.data()), vertexSpvBinary.size() / 4);

shcc::Resources resoucres = package.resources(); // Reflection information

info

Although shader shcc::Packages do depend on their corresponding shcc::Runtime to function, they hold a std::shared_ptr<shcc::Runtime> internally, preventing it from being destructed beforehand.
