Converting GLSL to TSL: Handling gl_FragCoord

In TSL (Taichi Shading Language), the equivalent of GLSL's gl_FragCoord is typically accessed through the fragment shader's input parameters.

The direct equivalent would be to use the position input parameter in your TSL fragment shader. Here's how you can convert your GLSL line to TSL:

TYPESCRIPTCopied
// In TSL fragment shader
fn fragment(position: vec2<f32>, resolution: vec2<f32>) -> vec4<f32> {
    let p = (-resolution.xy + 2.0 * position.xy) / resolution.y;
    
    // Rest of your shader code
    // ...
}

In TSL, the fragment position is typically passed as an input parameter to your fragment shader function rather than being accessed through a built-in global variable like in GLSL.

Note that depending on your specific TSL implementation or framework, you might need to adjust how you access the fragment position. Some implementations might provide it through a different parameter name or structure.
