Combining spherical mapper and anaglyph system
Horo set me off on this with his mind boggling Anaglyph_QTVR_Panoramas tutorial. There's a lot to think about. You have to look all the way around... which is challenging enough... and what happens when you look up and down? It's a dynamic situation in real life. Can such a thing be captured in one static image. Well yes, because clever Horo has done just that. What I wanted to do was find a way to do it in the minimum number of renders. Horo set the bar at 6 - for the 6 sides of a cube. I reckon, I can do it in 2... And fix the problem with up and down. Maybe... OK after extensive testing here's my prototype spherical map anaglyph. Things look like they go a bit funny at the poles... but once this has been remapped onto a sphere and viewed through the perspective camera - it all makes sense again - right up to the pole - so long as you don't see a pole everything is fine.
