Projection Puzzle
Posted: Wed May 24, 2023 9:32 am
I have a little puzzle for the trigonometry specialists here. In the node setup below you can see a little spotlight that I've scaled and rotated into a place where I like it. I would like to see that as the "neutral" setup. What I want to do now, is to stack a transformation on top of that so that I can rotate that setup in world coordinates. Let's say I want to light to come from the opposite side of the sphere, I would like to rotate the setup by 180° on the Z axis to achieve that. But now I would have to touch several value to get the light there.
In the unlinked node below you can see how I would rotate the light by 90°. That's basically what I want to do - but to the already transformed light. In Blender I can do that by sequencing vector transformations. But in Octane there doesn't seem to be a way to sequence projections.
I hope I have explained it well enough. Any help is appreciated.
