Rayshade

[Roger H. <rog...@mi...>]

I have finally built a version of RayShade which runs within my Macho/ 
Cocoa application.

I am seeing a problem with the RGB and Alpha channels being mixed up.  
I get no green, mainly cyan and white with some blue and magenta.  
This is on Intel.

Has anyone seen any similar problems with RayShade or is it my App?  
Though the app works with the interactive renderer and an other plug- 
in (non interactive) renderer.

Am I right in thinking RayShade is non interactive (in the Quesa sense)?

What does it put into the Alpha channel when rendering into an  
offscreen pixmap with an alpha channel? (The MicroSpot renderer sets  
all the background pixels to 100% transparent and normal objects  
pixels to 0% transparent and pixels which only have transparent  
objects, to their combined transparency)

Does RayShade support the background and foreground planes which Dair  
introduced a few years back?

Apart from that it looks good, speed looks OK though I've not thrown  
anything really difficult at it yet.
