Hey all,
I'm also adding this to the Gem tracker.
Its probably not possible, but I would really love a fast gaussian blur as a pix_ object. convolved blur does not have the image quality that would be really nice. Is there something that is similar in quality as gaussian blur but less intensive?
This may be a good test-case for pixel shaders...

Hi all,
<snip> I'm also adding this to the Gem tracker. </snip>
I mentioned the following a couple of weeks ago but I thought it would be good to add something to this list as well.
As GEM as a 3d external its really important to have some good support to handle already made 3d data. In this case we already have the model loader, but as soon as a you want to use the mapping, you added to the object in your 3d modeller GEM reaches its limits. So I really would like to have a handler for uv mapping data to create much more nicer 3d worlds

There's a law of probability that says that as you repeat a convolution product of Measures it will tend towards a gaussian (normal law) Measure with some centre and some std-deviation. In particular, repeating a uniform 1x3 blur will give something with zero centre (because of symmetry of the 1x3 kernel) and a std-deviation almost proportional to square-root of the number of compositions of the convolution. I think that this is the key to a fast simili-gaussian blur.
Does that sound right?
