two quick questions on shaders

[BadWolf]

Hi, First: I'm using minetest 0.4.7 stable on ubuntu, I was looking around trying to find the shader files, I can't find them. On Linux are they in some weird file path or are they not included in the stable release?

Second: When it comes to coding in glsl, are there any good beginner glsl coding guides out there? a quick search on the mine dev wiki for "shader" or "glsl" turned up nothing.

For those who know the language, how hard would it be to take a premade glsl script made for say blender and convert it for minetest? like a script featured here under a CC-BY license http://www.blendswap.com/blends/view/68937

I guess that was 3 questions. My bad

The shaders are in $path_share/client/shaders/, where $path_share is the Minetest directory in a RUN_IN_PLACE build, and /usr/share/ (or so) in a system wide installation on Linux.

Thanks PilzAdam

this would be sweet to implement: http://www.blendswap.com/blends/view/68857

If it was a straightforward conversion, which from what I see from the code, doesn't look like it would be :(

If I download that do I need to compile it or something? How would I add it to minetest.

You can ask RealBadAngel about how shaders work, because he is trying to add parallax mapping support to Minetest.

That's my question, but adding it to minetest will not be easy. It'll require coding. You could download that and play the demo in blender
