Re: ANNOUNCE: Realistic media plug-in for the GIMP v1.2
looks pretty cool, but it would be nice to have full control over color. perhaps that would be a future upgrade to it? bex

I am not familiar with the algorithm.. but just curious, would there be any difference if the Depth takes in negative integer (currently only positive accepted) ? Can you comment on this ? It wouldn't make any difference. The surface normal vectors would just point in the other direction, which is what you already get with "invert bumpmap". Federico

The local differences that are used to compute the surface normal would be exactly the same. Dude, follow the math! Read the source! Federico
some special effects
Hi, I am learning image proceesing nowadays. And I find that GIMP is really a nice place to visit. I have several questions. I like to implement some special effects by myself, such as 'Colored Pencil', 'Chalk Charcoal' in Adobe Photoshop. But I don't know how to do. Could anybody give me some advice about how to do? Thanks a lot! Best Regards, Bam _ 263Commail£¬ÆóÒµµÄµç×ÓÓʼþר¼Ò http://mail.263.net

Fiddle with any edges revealed by this It is frequently useful to see how the tile looks when tiled many times, to reveal any disturbing salient patterns. The above procedure can only help with the local edge transition but doesn't give you any overview Adding a special mode to Gimp seems like overkill to me, but hey - it's a popular request and all patches will be considered. I think it might actually be a good idea, but the design has to be thought out carefully while your thinking about it, something like an abstracted view plug in system could be nice. that way the tiled view would be a simple use of it. as could print preview, hightfields etc...
