fxPascal

[technomage]

Anyone used fxPascal for building vertex and fragment shaders for opengl :?: If so any idea where I can find some documentation in english

IIRC fxpascal compiles down to vertex/fragment assembler code, but now you want your shaders to be passed to driver as GLSL source.

Thanks for the tip I'm just startng to look into shader technology (my current system barely supports it in emulated mode) and I have to admit it can get a bit confusing, but if GLSL is the one to use then I'll use it

i've tried both. i used to write shader programs in assembler instructions but i tried fxPascal and implemented it in my last engine. It generally worked pretty neatly but it had a few shortcommings when working with multiple rendertargets and arrays and such. but generally i like it.

Glsl.. well i've used it a bit and frankly i don't see why i should use it. I havent' been able to find any reasons.

if it doesn't come with a pdf with all commands and syntax included then it is in Seth, an IDE for fxPascal

GLSL compiler is build in driver, while fxPascal translates to ARB vertex and pixel shader assmbler. And this really makes a reason!

For example:
* GLSL is more feature rich.
* Vendor driver can better optimize your code at higher level (and I bet vendor drivers doen't know anything about "style" & shortcuts of assembler code produced by fxPascal).

Sure, if anyone aims at GeForce3 level hardware - when it's better to code directly in assembler.

And for a GLSL Ide, i can recomend shaderdesigner, it's quite smooth:
