Hi,
I am pretty new to TD and am trying to build a patch where noise is displaced in a feedback loop and added to geo → render. I am having troubles with it not beeing displayed as I like and don’t know how to continue. If anyone would like to have a look and help me / explain to me what my issue is, that’d be amazing!
thanks

Hi there,
I’m not entirely sure what look you’re after, but I think the issue you’re having is that your noiseTOP is 8bit. This is the default setting in the common page ‘pixel format’ if it’s set to ‘use input’. 8 bit means that every pixel can only have 256 different color values and is always between 0 and 1. It can’t be negative. This is the reason why you see this sharp corner around 0,0,0.
If you change your noiseTOP to ‘32bit float (RGBA)’ for example and reset the feedbackTOP, you’ll see the points scattered around.
If you want to create particle systems driven by noise, also check out ‘instancing’. It’s possible to have just 1 boxSOP placed on many positions, resulting in the same output as you have now. Since this instancing is been run completely on the GPU, it’s much faster then first creation a SOP using the addSOP.
Hope this helps!
Cheers,
