Re: Sampler in Core Image Kernel

I have experimented extensively with CI kernels in the couple weeks since I've seen Quartz Composer, and put a lot of my compositions up on my blog at http://www.samkass.com/blog

It may not be the nicest code in the world, especially since I didn't know any GL-slang at all three weeks ago and online documentation is very sparse, but I'm learning and the more recent compositions might have some tricks you can use.

Hello,

I've just started to use a 'core image kernel' patch to work on image information at the pixel level.

Using the Cg code in the Star Shine demo as a template I see that the image data is stored in the form of a 'sampler' parameter.

Can people please point me to any further example code or documentation on the use of sampler and associated functions such as sample() and samplerCoord().

Many thanks in advance,

Nige
