This release has a reworked ray algorithm. HDRI are read in cross format. Voxel edges are smoothed. The image sampling has been improved. There are several types of cameras available that can do non-photo-realistic stroke rendering, motion blur or nightvision glow, and depth of field in real time. Shader definitions are read from the XML map file, which supports loading of .3ds and .ply files. The ability to remove and add shapes to the voxel tree interactively has been added. The build system has been ported to autotools, and the AMD-64 architecture is supported.
Most of the important functions have been rewritten since the last release. There is now a new raycasting algorithm that makes it possible to use a more compact tree format, so the tree generator has been reimplemented. It is now faster due to bounding boxes and should not create leaks anymore. The camera now uses an adaptive, interruptible sampling technique and the radiosity algorithm is based on a Monte-Carlo method.
This is a small release concerning new features. The authors had to
reorganize a lot, and as a side effect, the engine has become a lot
faster and looks better. Map files are now read using an XML syntax.
There is now a map for adding perlin noise to a shape. Rendering is done
with adaptive subsampling in a quad tree. OpenGL is used more often,
which speeds rendering on machines with good hardware.
