I am working in GL contexts, with one mesh and one videoplane blended, I want to get the RGB infos separately of each objects to jit.3m style.

With jit.gl.asyncread, it works for the master render window now.

And I tried to enable matrix output of the videoplane, which makes the video content dissapears....

Hi Jitterers,
I am working in GL contexts, with one mesh and one videoplane blended, I want to get the RGB infos separately of each objects to jit.3m style.
With jit.gl.asyncread, it works for the master render window now.
And I tried to enable matrix output of the videoplane, which makes the video content dissapears....
thanks in advance

if you need to analyze color information on individual objects or groups of objects, simply use a jit.gl.node @capture 1 sent to a jit.matrix:

matrixoutput is only for geometry, not pixels

However, now I am confused with the jit.gl.node 's output to my render window as I just need its data.

As the patcher attached, what I want to achieve is: Blend the videoplane with the mesh, while I can have access to the videoplane's full frames color info (as I move around the positions) prior to blending.

If I capture the videoplane with node, it seems rendering another layer that blocks my original blendings.

Thanks Rob ! This helps.
