Indigo Renderer Forum

Hi all,

i wrote up a little ISL beginner tutorial, let me know what you think and if its to complicated to understand

Btw, its a pretty rough preview-ish thing and it needs some polish and spell checking, hehe.

Cheers!

Very informative. I like the no nonsense style and I have learnt a bit more about ISL than I knew before - not hard!

I have to say though that even after reading your PDF that for someone like me, ie dumb , ISL is still not easy or intuitive to use.
I guess I'm the kind of end-user that needs pre-sets to start with or some kind of previews while I tweak the ISL numbers

thanks a lot fused, this is long awaited and I look forward to more such stuff

btw: why you guys don't use the wiki functionality for such things anymore?

Very helpful information!

Thanks Fused, sounds easier now

I overlooked this, thanks fused !

Hope again !!!

Hi Fused,
Nice to see more about ISL. I 've been playing around with a shader for wood and trying to work some of this out is trial and error.

Something that would be very useful is a description of the parameters passed into the eval() functions, and what is meant by the different types of coordinates (e.g. UV, ST, etc).

Also, for people not used to functional programming, a description of how to implement a loop with recursion might help. But I'm sure all of this and more is coming in the future tutorials!

Cheers,
gra.

I'm not sure if recursion is allowed at the moment. I was told me its unsecure and probably not allowed.
