Read pixels from render to target texture

Questions
1

Hello,

I am using the GPUComputationRenderer.js. I followed the https://threejs.org/examples/webgl_gpgpu_birds.html example and then got to the render part:
this.gpuCompute.getCurrentRenderTarget(this.myVariable).texture;

Of course, the texture.image.data does not exist since this data is on the CPU. My question is, how can I read the rendered pixels from the GPU from the returned texture above ?

Note: I already saw the https://threejs.org/examples/webgl_gpgpu_water.html example but the WebGLRenderTarget has type THREE.UnsignedByteType instead of THREE.FloatType. So, I assume the readRenderTargetPixels will not work in my case.

Thanks.
