It does not document it on the README. When I try my intuition,
<script type="x-shader/x-fragment" id="image" src="shader.frag">The shader does not compile.
Hi, neat project! I know an npm package is planned and am selfishly creating an issue to get notified when that happens.
Hello and first of all, thank you for this project.
I was able to 'import' shaders from shadertoy very easily.
I'd like to ensure that I can build the runtime myself, so I tried on archlinux:
$ ./gradlew compileJs

What can I do to diagnose the issue ?
Thanks a lot
My shader has:
uniform vec2 iThingsPos[8];And in the js I do:
shaderWebBackground.shade({
canvas: ref.current!,
shaders: {
image: {
uniforms: {
iThingsPos: (gl, loc, ctx) => gl.uniform2fv(loc, new Float32(...))
},
},
},
});I'm getting this runtime error
shaderWebBackground.ConfigError: No configuration for uniform "iThingsPos[0]" defined in shader "image"
Is there a trick for passing array uniforms with this library?
Thanks for open sourcing this btw, great little library!
