Blending 3D Environments in Anaglyphic 3D

Gutterkisser's picture

Hi all.

I've hit a roadblock with anaglyphic (red/cyan) 3D visuals in QC. No doubt a collective groan is let out at the very mention of gimmicky 3D, but please bear with me!

The actual 3D effect works fine, in terms of X-axis offset of two 3D Spaces, and the red/cyan blend.

The problem I'm having is I can't figure out how to blend the two 3D Spaces WITHOUT using Render In Image (and twice, at that). Render In Image tends to cripple the frame rate on my machine, so any motion is jerky and destroys the 3D effect.

Is there a more efficient way of layer blending 3D objects?

I've attached a basic .qtz example- two Render In Image macros blended through an Anaglyph Blend patch. Both Render In Image is an ugly nest of Render In Image > 3D Space > Lighting > 3D objects, and that's where my computer is struggling.

My aim is for everything to sit inside one 3D Space. Each object within that Space would be duplicated with appropriate X-axis offset and red/cyan colour difference. However, here I'm not sure how to blend their overlaps with the appropriate effect - changing the Blend Mode of each object to 'Add' doesn't quite work.

...Wow, apologies for the wall of text guys - hope you can wade through it all, any suggestions or feedback will be greatly appreciated!

This is a composition that uses sample and hold, with blend with mask mode, to create an effect that lets you "erase" between a snapshot from the video cam, and the current feed.

Another image source could be used in lieu of the sample and hold video shot. Tweak the interpolation duration to change the snapshot delay.

The initial idea, for me, was to take a snapshot while out of the view of the cam, walk into the cam feed, and then "erase" over parts of my body! An older composition...

funny reactive k3d blend shapes.

so well this funny to me cause its my head or a picture of me i wrapped around a sphere then made into audio reactive mesh blends as an experiment in realtime 3d deformations.

i know the models are large there are 4 of them i haven't yet converted them to fbx, and they are really large i sub divided them twice. so that is the level of detail that eventually will be rendered but agreeably to large to wrap just a pic texture around. eventually it will be a talking head but i wanted to play in qc a bit with some audio so this is the test render.

so i still have to sculpt out the finished head i am hoping to be able to blend 10 shapes but am having a lowered frame rate with 4 at the moment but i think that is because obj is sluggish.

does anyone else think this a funny visualizer.
