Implementing GLSL's discard in TSL

In GLSL, the discard keyword is used to exit the fragment shader early and prevent the fragment from being written to the framebuffer. When converting this functionality to TSL (Three.js Shader Language), you can use the dontWrite function.

Here's how you can convert your GLSL code to TSL:

TYPESCRIPTCopied
// TSL equivalent of: if (gl_fragColor.a <= 0.0) discard;
if (outputColor.a <= 0.0) {
  dontWrite();
}

The dontWrite() function in TSL serves the same purpose as discard in GLSL - it prevents the fragment from being written to the framebuffer and exits the shader execution for that fragment.

Make sure to use this within your fragment shader function where you're determining the final output color.
