Is it possible to capture a jit.gl.node's (or jit.gl.camera's) depth map? Whenever I try I only get strangeness (e.g. white artifacts).

Something else I noticed was some "touchy" behavior of jit.gl.node regarding shaders

Did I miss something?

btw, i'm using node capture in here: https://cycling74.com/forums/sharing-triplehead2go-rendering-setup-updated-for-max6-and-jit-gl-node


Yes I had a look at your patch while looking into node. Great work! :)

What I want to capture is the depth buffer: 

I am trying to get shadows for my scene and therefore I wanted to explore node and camera's possibilities. Especially the later one being able to control the scene and (perhaps?) making the light-perspective render pass more lightweight.

I was thinking to do it within the shader in the first place.. but unfortunately neither node nor camera work with shaders. Or do they?

i see, sorry can't help with that. that's gl territory i haven't explored yet.

Nevertheless, thanks for your input. Not only with this issue, but everywhere on the board. I've learned a lot.

hi mark2e, check out the technique for capturing depth information in the following DOF implementation:

Yes, I've had a look at that. And that's the way I wanted to do it in the first place. But I wanted to test if node and/or camera could somehow be abused to "simulate" a second render pass. And as I could not get a shader working in node itself I looked for an alternative way of getting the depth info.

while you can use multiple gl.cameras to capture multiple passes of a scene and process those textures together, there unfortunately is no way to apply shaders to the groups of objects captured in the scene before capturing.

so, at this time, the method in the patch linked is still the preferred way to go about this.

we can look at some ways to ease this process in the future.
