@EMComputeShader
class MyCompute {

    var tex: MTLTexture?
    var intensity: Float = 0
    
    var impl: String {
        "float2 floatGid = float2(gid.x, gid.y);"
        "float2 center = float2(tex.get_width() / 2, tex.get_height() / 2);"
        "float dist = distance(center, floatGid);"
        "float color = intensity / dist;"
        "tex.write(float4(color, color, color, 1), gid);"
    }
    
    var customMetalCode: String { "" }
}

v2.2.1 (previous)

    @ShaderStringBuilder
    override var impl: String {
        "float2 floatGid = float2(gid.x, gid.y);"
        "float2 center = float2(tex.get_width() / 2, tex.get_height() / 2);"
        "float dist = distance(center, floatGid);"
