m3d is a small but quite functional library for visualization of a 3D space which is filled with lines, rectangles, triangles and 'markers'.
When you want to visualize something special, which is not covered by the options of hard-coded layouts.
There is also possibility to draw a text using any available font in this space. Text in this case will be converted in a set of 3D lines.
Also all above is quite useful to visualize some economic or scientific information...
Actually I've wrote this library to visualize distribution of performance and response time dependencies of the multiuser automatic performance testing.
