View Full Version : Writing scipts and shaders
11-13-2003, 05:07 AM
Does anyone know if I have to use an external compiler to write scripts and shaders, or can I do it in something like Notepad?
The docs mention C++ compilers, but I'm wondering if I need it.
Oh, and I got my Studio today!! Yipee skippee!!

I think I found my answer in the docs; which is "yes" I do an external compiler, but if someone would confirm this for me?
afaik you need c not c++, but i could be wrong.

It's not easy to find stuff in the Messiah documen's.
As I understand it the best thing to do is to open up every single page and se what there are on them.
from your writing I suppose that you have found the 'General Info/Develop/C language Reference' but there is also another section called 'General Info/Expressions & Messiah:script' that I missed myself when searching the first time.
If you read the section 'General Info/Expressions & Messiah:script /Messiah:script/Overview' you will see among other things that no compiler is needed for scripts as they are compiled when messiah starts up (at least if I get it right).
I do however not know what can be done as a script or how fast it is. If you need to write a 'real' plugin you will need to write it in C and compile.
I'm not a C programmer myself but from what I saw when looking at it it seems to be well documented and they even explain how to set the project up in Microsofts Visual C++ v6 and v7 so if one knows C i don't think it should to hard to figure it out.

Shaders can be either scripts or pre-compiled plugins. Scripts can be written in any text editor, I use Jext, and are compiled by messiah on launch. There's a script log in the messiah dir you can check for compile errors.
Plugins are pre-complied C. The base system is C but you can use C++, with a few conditions. These are covered in the SDK docs. I use MS Visual C++ for plugins.
There are a couple shader scripts included in messiah. Look in the scripts directory for examples.
Building a script shader will allow you to have a standard connection node, but if you want a custom interface panel in the left bar I think you have to do a pre-compiled plugin.
PMG stated that the shader architecture is similar to renderman and concepts should transfer well.

Thanks for your help guys. I did find the scripts docs. I'll start there, as they suggestd, and then I'll invest into an external compiler if needed.
