XJRT is an open source Java renderer with a ray tracing backend. Objects can be fed into the renderer either through Java or an XML-based scene description language. Shaders can be written in Java and are instanced using the reflection API. The renderer currently supports a variety of polygons, polygon model formats (3ds, DXF, OBJ, and OFF), spheres and other quartics, cubic patches, heightfields, boxes, torii, blobbies, algebraic surfaces, constructive solid geometry (CSG), and a variety of light sources. Support code is provided for doing tiling, bump mapping, noise based texturing, camera based motion blur, and depth of field.
