Fisheye Lens Shader for Renderman

Below is a link to the source code for the shader. I use three renderers (BMRT, Entropy, and PRman), each with its own slightly different syntax for doing raytracing. Hence, I have three slightly different versions of the shader and the example RIB files below. The diffferences are just a couple of lines. The current version is 1.2, updated 2/24/05. See the notes in the source code for usage details.

• fjs_fisheyelens_bmrt.sl (4 kb)
• fjs_fisheyelens_entropy.sl (4 kb)
• fjs_fisheyelens_prman.sl (4 kb)

*** Please note that version 1.1 contained a small error. Update to 1.2. ***

Here is the older version 1.0, which was used with BMRT:

• fjs_fisheyelens_v1.0.sl (4 kb)

Example #1 - Images and RIB Files

Image	Description	Files
	This image is of a normal scene. It is just a bunch of colored polygons placed in front of the camera. This RIB file works with all of the renderers.	no_lens.rib no_lens.jpg
	Here is the same scene viewed using the fisheye lens shader. The fisheye lens angle is set to 90 degrees, which is the same angle as the standard camera in the above scene.	with_lens_90_bmrt.rib with_lens_90_entropy.rib with_lens_90_prman.rib with_lens_90.jpg
	Here is the same scene viewed using the fisheye lens shader with the fisheye lens angle is set to 120 degrees.	with_lens_120_bmrt.rib with_lens_120_entropy.rib with_lens_120_prman.rib with_lens_120.jpg
	Here is the same scene viewed using the fisheye lens shader with the fisheye lens angle is set to 150 degrees.	with_lens_150_bmrt.rib with_lens_150_entropy.rib with_lens_150_prman.rib with_lens_150.jpg
	Here is the same scene viewed using the fisheye lens shader with the fisheye lens angle is set to 180 degrees.	with_lens_180_bmrt.rib with_lens_180_entropy.rib with_lens_180_prman.rib with_lens_180.jpg

Example #2 - Images and RIB Files

Image	Description	Files
	Here is a scene that shows the full extent of the fisheye lens. It is simply a hemispherical arrangement of colored polygons around the camera. The fisheye lens angle is set to 180 degrees.	fisheye_180_bmrt.rib fisheye_180_entropy.rib fisheye_180_prman.rib fisheye_180.jpg
	Here is the same scene with the fisheye lens angle is set to 150 degrees.	fisheye_150_bmrt.rib fisheye_150_entropy.rib fisheye_150_prman.rib fisheye_150.jpg
	Here is the same scene with the fisheye lens angle is set to 120 degrees.	fisheye_120_bmrt.rib fisheye_120_entropy.rib fisheye_120_prman.rib fisheye_120.jpg
	Here is the same scene with the fisheye lens angle is set to 90 degrees.	fisheye_90_bmrt.rib fisheye_90_entropy.rib fisheye_90_prman.rib fisheye_90.jpg
