Graphic utility library based on wgpu.

Sample Codes

wgsl-sandbox

A sample of creating a render object by implementing "Rendered" in a new structure.

One can use xyr WGSL shader in the following way:

• Enter the shader path as an argument when executing the program.
• Drag and drop the shader into the window.

The rule of shaders:

• One can draw a image by implementing the function:

wgsl vec4<f32> main_image(coord: vec2<f32>, env: Environment);

• The parameter coord is the fragment coordinate. The origin is the lower left.
• The parameter env has the environment information. The declaration of struct is the following:

wgsl struct Environment { resolution: vec2<f32>; // the resolution of the image mouse: vec4<f32>; // the mouse information behaving the same as `iMouse` in Shadertoy. time: f32; // the number of seconds since the application started. };

Also, see the sample newton-cuberoot.wgsl, default shader, in examples.
