Duplicate shader window

[bruno...@neuro.fchampalimaud.org]

Hi everyone,

I am looking for a way to duplicate a shader window. I want to be able to see a small online window of what i am displaying on a second monitor. Additionally, is there an easy way to grab the shader content and convert it to a IPIimage that I can use to videoWrite with?

I thought about using screenCapture to solve both probes but I wonder if there is another way that doesnt depend on the ROI the shader occupies.

Thanks,

Bruno

Hi Bruno,

There is a way to grab the content of the shader window using the ReadPixels node.

Be aware that this might impact your render pipeline depending on complexity, hardware, etc. Also you need to make sure all the drawing commands have been flushed to the viewport using DrawViewport. For example:

The output of ReadPixels is already an image which you can manipulate and save.

Hope this helps!
