Talk:Shading language

This page lives again (by itself)

After trying to put this topic in shader, I realized it's better for it to have its own page. This makes the two readings much more friendly, they were way too long when merged. MaxDZ8 _talk 18:20, 6 March 2006 (UTC)

Should SDL be put in here?

Should POV-Ray's SDL be put in here?

I'm not really used to it but I believe it should. SDL seems to have rather non-standard features like the ability to describe a whole scene and not just surfaces. I'm not really confidend with offline shading languages so this is just a feeling.

SDL in Povray context means "Scene Description Language". Since it is not meant for any purpose other than input to Povray, I wonder what is "nonstandard" about it? —Tamfang 03:46, 27 July 2006 (UTC)

Look, I'm not really used to it but that's the few I get about: the "shading" subsystem of SDL is definetly a shading language but the same can be used to describe the whole scene. It definetly does not look like a realtime shading language. Maybe offline renderers use this, but as far as I know renderman itself does not have this functionality (besides geometry amplification).

What I really wanted to mean is that I guess some people will say this is stretching it, but for me SDL can be used to shade, so it's also a shading language.

You're ancouraged to lighten us on this issue ;)

SDL describes a network of high level nodes linked together. As such, it is just the text-version of what people do in e.g. Maya using the Hypershade or in XSI using the RenderTree. If you count Pov SDL as a shading language, so is a Maya ascii file as it stores what a user has laid out in the Hypershade and as it allows manipulating it by means of a text editor. So no, I don't think Pov SDL is atomic and close enough to the actual shading process enough to go by as a "shading language" at all.

As I read the main article, I wondered "What about POV-Ray? Why isn't it listed?" I suppose this is an anti-ray-tracing bias? POV-Ray inclused shading in its language, even if it does include scene description as well. — Preceding unsigned comment added by 24.4.155.39 (talk) 03:24, 10 April 2014 (UTC)

what about GLSL ?

shouldn't GLSL be present in this article? --TiagoTiago (talk) 16:29, 12 May 2009 (UTC)

It is. Real time rendering -> OpenGL shading language. GLSL has its own article, albeit short, and I'm against the idea of possibly merging it there.

Jargon

Due to inaccessible language, I have inserted an elucidation message. However, I am unsure if the content can be expressed in any other manner.--Soulparadox 11:05, 9 June 2012 (UTC)

Open Shading Language

Should perhaps be added. Don't know enough about it myself, or I'd do it. 216.232.157.160 (talk) 10:31, 2 September 2013 (UTC)

Please Clarify VEX Language

"However, its integration into a complete 3D package means that the shader writer can access the information inside the shader, a feature that is not usually available in a rendering context." What does that mean? — Preceding unsigned comment added by 198.7.247.194 (talk) 20:27, 7 March 2014 (UTC)
