From AnimatedComputeShaderPanel to ComputeShaderPanel in WinUI 3

[diluculo]

I'm currently working on visualizing voltage distribution in a WinUI 3 app. Currently, I'm using AnimatedComputeShaderPanel of ComputeSharp v2.0.3, but I'd like to migrate to ComputeShaderPanel since the calculation at each pixel coordinate isn't actually time-dependent.

My first question is whether ComputeShaderPanel is suitable for static visualization tasks. If so, I would like to know whether it can help reduce the GPU load.

Here's the code snippet using AnimatedComputeShaderPanel:

<computesharp:AnimatedComputeShaderPanel x:Name="ShaderLayer"/>

And in the code-behind, I'm setting up AnimatedComputeShaderPanel like this:

ShaderLayer.ShaderRunner = new ShaderRunner<Heatmap>(t => new Heatmap(settings, ... ));

The shader Heatmap is

    [EmbeddedBytecode(DispatchAxis.XY)]
    [AutoConstructor]
    public readonly partial struct Heatmap : IPixelShader<float4>
    {
        [AutoConstructor]
        public readonly partial struct Settings
        {
            public readonly Bool isDarkTheme;
            public readonly Bool renderingAxisLines;
            // other properties...
        }       

        // other settings and private methods...

        public float4 Execute()
        { 
            // Shader execution logic...
        }
    ));

When attempting to switch to ComputeShaderPanel in XAML, however, I encountered no rendering result.

Could you guide me on how to accomplish this task? Thank you.
