- fixed makefile to produce non-broken shared objects
- removed glutGetModifiers from the motion callback and placed it in the mouse
callback as apparently it's not supposed to be called from there.
- added MacOSX include paths in the examples

1 metasurf - a library for implicit surface polygonization
3 1. Overview
4 -----------
6 Metasurf is a library for implict surface polygonization. You only need to
7 set a callback that returns the scalar field value at any given point in
8 3-space, and another callback to accept isosurface vertices. Then at any point
9 just call msurf_polygonize, and the library handles everything else for you.
11 2. Usage
12 --------
13 The following snippet is sufficient to draw the surface of an implicit unit
14 sphere, centered around the origin.
16 struct metasurface *ms;
18 /* initialization */
19 ms = msurf_create();
20 msurf_eval_func(ms, eval);
21 msurf_vertex_func(ms, glVertex3f);
23 /* drawing */
24 glBegin(GL_TRIANGLES);
25 msurf_polygonize(ms);
26 glEnd();
28 /* evaluator */
29 float eval(float x, float y, float z)
30 {
31 return (x * x + y * y + z * z) - 1.0;
32 }
34 See the examples subdirectory for more examples.
