2) to generalize the notion of user data space from the two-dimensional drawing space of MetaPost (and the represented page), and affine transformations of this 2D space to other coordinate systems and dimensions. We are not thinking about 3D rendering or raytracing, but rather simple projections and other transformations such as polar coordinates. (Of course, log scales, for example are a "simple" non-linear transformation.)

On this note: I would like to have an ‘official’ way to map 3D coordinates to 2D coordinates with for a camera position with an orthogonal window. Not the most complicated thing in the world, but it would be nice if metafun had an ‘official’ way of setting up a scene. Best wishes, Taco
