Come on to Evas 2010 ;-) Actually, even Edje supports it. You can see examples in expedite "Map" tests or http://www.rasterman.com/files/map.edc for a stand-alone Edje file. I guess Elementary also ships with a test. Map is not really 3d, is just 2d manipulation of shapes according to an output grid. This grid can give the effect of perspective, rotation and as it takes vertices colors, it can do light/shadow effects, as helped by various Evas/Edje high-level calls. http://www.youtube.com/watch?v=edLTo61dIgA http://www.youtube.com/watch?v=6tuVSkrdjiE Evas is quite low-level and does the basics. More complex shapes like spheres and meshes that composes full-bodies like a game character should be done elsewhere, like an smart object that loads 3d-studio/maya/blender3d output files and build them from triangles with individual transformations. This is also the same for more complex shapes like circles and ellipses, that should be made into polygons (but no-one ever wrote these, probably lack of requirement/time/interest). Note that the current Evas implementation does not account for the "z" hint and lacks the fixes to make it really look like 3d, then you have some distortion. This is to be fixed when time allows (according to Rasterman).
