Texture Type in Three.js Node Material System

Based on your code example, you're working with the Three.js node material system and specifically using tslFn to create a custom shader node that processes a texture.

For the texture parameter in your setLayout function, the appropriate type would be 'sampler2D'. This is the GLSL type that represents a 2D texture sampler in shaders.

Here's how your corrected code should look:

JAVASCRIPTCopied
const test = tslFn(([texNode, uv]) => {
    // ... some logic
    return texNode.uv(transformedUV);
})
.setLayout({
    name: 'test',
    type: 'vec4',
    inputs: [
        { name: 'texNode', type: 'sampler2D' },
        { name: 'uv', type: 'vec2' }
    ]
});
const texNode = texture(anyTexture);
this.colorNode = test(texNode, uv);

The 'sampler2D' type is appropriate here because:

1. It's the standard GLSL type for 2D textures
2. When you create a texture node with texture(anyTexture), the resulting node represents a sampler2D in the shader
3. The .uv() method you're calling on texNode is typically used with sampler2D textures to sample them at specific UV coordinates

If you were working with other texture types like cube maps, you would use 'samplerCube' instead.
