Hello all, Firstly let me start by saying I’m a 3D and cg/vfx enthusiast rather than a professional. I’ve only been experimenting with blender for a couple of months when I can but used other products over the years going back to POV on a 386.
For the actual question
I’ve trying to experiment for projection mapping 3d animation onto a physical 3d surface. My own upcomming wedding cake. Searching and guides seem to be around using VPT, madmap to warp and project the content but not about how the create the content. I’m not looking for advice on modeling animation etc here but how would I go about rendering the output for the projector but from the viewers point of view.
If I had the projector in line with the viewer I could model the scene and render and see this working. However I require to project from an offset to the viewer but with the perspective relative to the ideal viewing location. In truth I’m having difficulty seeing what I need to do and how I would achieve it with blender.
My line of thinking is I model the scene with 3d animation and morphing.
Render to a camera in a position as the target viewer.
Then use camera projection to project that output to a fixed model.
Render to camera at the position the projector will be located or multiple cameras face on to each face. (this might make it easier in VPT etc and could be re used)
Does anyone have any advice
