Re: Aqsis - Open source rendering software
-----------------------------------
It works...sort of :doh: 

Went to Pixar's website and read the Renderman Compliant specification.  I then took a look at a test rib I exported from Poser and made a couple of hacks to the file.  I finally got a partially rendered scene with enough errors to give me an idea of where to go next.

It seems that Poser's RIB specifies an output about the size of a pin head. Looking at the first few lines of the RIB looks like this:

##RenderMan RIB-Structure 1.0
##Scene Saved
##Creator Poser 4.0
##Frames 1
version 3.03
FrameAspectRatio 1.000000
ScreenWindow [-1 1.000000 -1 1.000000]
Projection "perspective"  "fov" [36.960341] 
Clipping .01 1000.0 
FrameBegin 1
Transform [1.000000 0.000000 0.000000 0.000000 0.000000 0.996195 -0.087156 0.000000 0.000000 -0.087156 -0.996195 0.000000 0.019716 -0.359022 1.530000 
1.000000]
WorldBegin

I made the following changes:

##RenderMan RIB-Structure 1.0
##Scene Saved
##Creator Poser 4.0
##Frames 1
version 3.03
[b]Format 640 480 -1.0[/b]
FrameAspectRatio 1.000000
ScreenWindow [[b]0[/b] 1.000000 [b]0[/b] 1.000000]
Projection "perspective"  "fov" [36.960341] 
Clipping [b]1[/b] 1000.0 
FrameBegin 1
Transform [1.000000 0.000000 0.000000 0.000000 0.000000 0.996195 -0.087156 0.000000 0.000000 -0.087156 -0.996195 0.000000 0.019716 -0.359022 1.530000 
1.000000]
WorldBegin

I added or changed the bold items.  The Transform line is supposed to translate the camera position, but it still gives a parser error.  Also, Aqsis wants Tiff format textures not Jpegs.

I finally got an image big enough to see, but it was dark.
