speed of simple animations. ximage is an image viewer for viewing HDR Radiance images. It can adjust the simulated exposure and apply some of the human visual effects of pcond. Integration rad is a front-end which reads a '.rif' file describing a scene and multiple camera views. Previously, make and a makefile were used in a similar role. rad coordinates oconv, mkillum, rpict/rview and other programs to render an image (or preview) from the source scene file(s). trad is a GUI front-end to rad using Tcl/Tk. ranimate''' is a front-end which coordinates many programs to generate virtual walk-through animations i.e. the camera moves but the scene is static.
