- Persistence of Vision Raytracer
- Version 1.0
- -------------------------------
-
- The Persistence of Vision Raytracer creates
- three-dimensional, photo-realistic images using a
- rendering technique called ray tracing. It reads in a
- text file containing information describing the objects
- and lighting in a scene and generates an image of that
- scene from the view point of a camera also described in
- the text file. Ray tracing is not a fast process by any
- means, but it produces very high quality images with
- realistic reflections, shading, perspective, and other
- effects.
-
- This version was ported to the Acorn Archimedes by
- Pete Goodwin, July 1992. This supersedes versions of
- !PVray (1.7.2) and is the successor to Beta 0.5.
-
- This version is approved by the POV-Team, but it is
- not an official release and they have no way of
- supporting it. They will try to answer any questions
- where they are able, though. Any problems or queries
- about this version should be directed to me, Pete
- Goodwin.
-
- This version has a front end (called Front) that
- starts the ray tracer main task (called POVray). The
- file !RunPOV is called by Front and the parameters
- passed to !RunPOV. It is possible to run the raytracer
- without the use of the front end application by studying
- the manual for the command line switches to POVray. In
- summary these are:
-
- +i<filename> input scene filename
- +o<filename> output image filename
- +w#### width of image in pixels
- +h#### height of image in pixels
- +v verbose option (not implemented in
- desktop version)
- +d## display mode of previewer
- +f? where t, d or r indicates Targa, Dump
- (QRT) or Raw output file format
- -f disable file output
- +s#### start line for tracing portion of screen
- +e#### end line for tracing portion of screen
- +c continue an aborted partial image
- +b#### buffer size. This should be 16 - it
- indicates the size of file buffer in
- kbytes. If you use -b0, it closes the
- file every line - safer but much slower!
- +a#### antialiasing
- +q# quality
- +l<path> library path
