Leveller now supports animations whose camera paths are defined from vector shapes (one for the camera position and another for the look-at point). Either path is optional in which case the camera stays put or it moves but looks at a fixed point. The altitude of either path can vary between two elevations. Example AVI video (different codecs, most compatible ones first) of a camera following a large circle while looking at a straight line running from northeast to southwest:

The raytracer now includes textured billboard reference shapes, so one can render foliage, etc. at high quality. Antialiased raytracing (with sufficient sampling) is better than OpenGL's mipmapping but of course takes longer. Example:
