OpenCSG is a library that does image-based CSG rendering using OpenGL.
OpenCSG is written in C++ and supports most modern graphics hardware.
CSG is short for Constructive Solid Geometry and denotes an approach
to model complex 3D-shapes using simpler ones. I.e., two shapes can be
combined by taking the union of them, by intersecting them, or by
subtracting one shape of the other. The most basic shapes, which are
not result of such a CSG operation, are called primitives. Primitives
must be solid, i.e., they must have a clearly defined interior and
exterior. By construction, a CSG shape is also solid then.
Image-based CSG rendering (also z-buffer CSG rendering) is a term that
denotes algorithms for rendering CSG shapes without an explicit
calculation of the geometric boundary of a CSG shape. Such algorithms
use frame-buffer settings of the graphics hardware, e.g., the depth
and stencil buffer, to compose CSG shapes. OpenCSG implements a
variety of those algorithms, namely the Goldfeather algorithm and the
SCS algorithm, both of them in several variants.
XaoS is an interactive fractal zoomer. It allows the user to
continuously zoom in or out of a fractal in a fluid, continuous motion.

- Enable WebM encoding.
- Stop stripping the shared libraries which explains why I was
seeing no symbol table with the shared libraries.
- Build all of FFmpeg with -fomit-frame-pointer on i386 instead of
hacking the various Makefile's and having to add more files as
further updates are made. Use default CFLAGS (-O2) on i386 now too
instead of overriding with -O.
- Remove the UINT64_C hack.
- Update HOMEPAGE to use the ffmpeg.org domain.
- Various other cleaning up and fixes for the port.

General purpose interactive viewing program for Unix. It is used
mostly for 3D graphics but can display data in 2D and 4D as well.
