Evening... I`m looking for some kind of graphics editing software, allowing to draw 3D sketches and view them through anaglyph glasses (blue-red). The main purpose is just to assist my imagination in solving 3D geometry problems, so I prefer it to be as simple as possible. It would be great if there will be a feature to set the distance to the cursor using the mouse wheel or something like that. Does such a thing exist? At least, something similar? Or should I code it myself? Deep thanks!
