Rust-GPU —— 面向 GPU 编程的 Rust

Rust-GPU 是面向 GPU 编程的开源项目，目标是使 Rust 成为 GPU 着色器开发的“一等公民”编程语言和生态系统。

示例

 use glam::{Vec3, Vec4, vec2, vec3}; #[spirv(fragment)] pub fn main( #[spirv(frag_coord)] in_frag_coord: &Vec4, #[spirv(push_constant)] constants: &ShaderConstants, output: &mut Vec4, ) { let frag_coord = vec2(in_frag_coord.x, in_frag_coord.y); let mut uv = (frag_coord - 0.5 * vec2(constants.width as f32, constants.height as f32)) / constants.height as f32; uv.y = -uv.y; let eye_pos = vec3(0.0, 0.0997, 0.2); let sun_pos = vec3(0.0, 75.0, -1000.0); let dir = get_ray_dir(uv, eye_pos, sun_pos); // evaluate Preetham sky model let color = sky(dir, sun_pos); *output = tonemap(color).extend(1.0) }
