Java Manifolds

About

Java’s transformation library is capable of only affine transformations. This put an end to my curiosity when it came to distorting existing java games and toys, though I always wanted to create something that could render on an arbitrary surface. This library is a proof-of-concept rendering library that can render to a plane, translate all the points through a function, then plot them to the screen.

As a quick example of what that transformation may be, the screenshot on this page is of a circle rendering onto a (ln(),ln()) plane. Arbitrary functions are possible, though the number of drawing primitives is limited due to speed issues, and I had to rewrite the way Java renders shapes in order to make the distortions possible.

The source tarball for this one has been lost to time — it survives only as the proof-of-concept described here.

Usage

Compile using make, run using Java Test. Examine the test script to see the API, but it’s clear that it isn’t very well developed yet.
