The Radon transform is used to take 2d projections of an object and create a 3d representation.
It seems like it would be possible to apply such a transform in 3d graphics in games (although possibly too slow to be practical).
For example, a very simple way to display an object is to use a 3d rectangle and texture map each side. This is relatively fast but the 3d detail is limited. When a side is parallel with the visual plane it will represent the detail 100% (so the visual detail would be limited to that of the texture map). Of course it won't represent external 3d effects properly, like lighting.
But by using the Radon transform one could gain a true 3d approximation of the object from the six textures/projections used. By increasing the number of textures/projections the approximation is better.
I'm curious if the idea has potential. Possibly for high-quality 3d models it might pay off in performance and size. Of course 3d models can be optimized to limit their size which also increases speed but visually doesn't change much.
