Objects can be displayed as points, wireframe, solid polygons, textured polygons and shaded using plain colour, depthcued (z-order) or light-sourced - things can be rotated around and moved about to make cool demos. A simple linear-additive lighting model with any number of coloured lights can be applied to solid objects.
K3D has been superseded by phoria.js - the replacement for K3D written by the same author - now with full 3D camera, matrix transformations for each object, scene graph, particles, UV texturing, basic physics etc.
