Re: Bumpmap with negative Depth ??
Thanks for your explanation. 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 ? If the bumpmap can be improved, many other scripts/plugins which calls this will benefit from it.. re, lasm gallery-> http://gug.sunsite.dk/gallery.php?artist=41 --- Federico Mena Quintero <[EMAIL PROTECTED]> wrote: > > The Bumpmap plug-in works by taking the intensity values to be height > values and computing the surface normal at each point.

ANNOUNCE: gimp-print 4.1.3
Gimp-Print 4.1.3 is a development release in the 4.1 line. This version marks a complete reorganization of the source tree. Gimp-Print now uses the GNU build tools much more comprehensively in the past. It builds a single shared library that the Gimp plugin and the CUPS driver (and perhaps other future applications) can link against. This new architecture will make for a much better system, but this particular release is more likely to be unstable than most due to the rather radical change in architecture. Gimp-Print 4.1.3 contains the following fixes and improvements over 4.1.2: 1) The source has been completely reorganized. Please read the README file for more information! 2) Improvements to the Lexmark driver. -- Robert Krawitz <[EMAIL PROTECTED]> http://www.tiac.net/users/rlk/ Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail [EMAIL PROTECTED] Project lead for The Gimp Print -- http://gimp-print.sourceforge.net "Linux doesn't dictate how I work, I dictate how Linux works." --Eric Crampton

Then it does simple Gouraud-like shading on the destination image. Inverting the bumpmap source is exactly the same as using the "invert" button on the plug-in's dialog box; the intensity values are inverted and the surface normals will point in the opposite direction. I.e. it is essentially a cheap embossing effect. Photoshop's Lighting Effects produces much better results because it actually does Phong shading of the image, and it general it has better lighting models that you can choose. You can do this in the GIMP with Tom Bech's plug-in of the same name. Federico
Re: psd_save plugin for gimp 1.2 not saving masks
Hi Thanks for you mail, but I have a bad news, in this moment Monigotes Animacion have not programers to develop more Plug-in (Gfli_Patch and psd_save), we are received some E-Mail, with patch to this plug-in, (only for Psd_Save). We only can let some web space for the develop, at http://www.tridentemonigotes.com If you think that god idea please tell us, and any way I will put the E-Mails in one Week Regards Vittorio Pirajno Vegard Vesterheim escribió: > I did a quick attempt at porting the psd_save plugin (allows saving in > Photoshop format) to gimp 1.2.

Re: Bumpmap with negative Depth ??
What he is suggesting is to invert the color value, so white becomes black, and black areas become white, so that the bumpmap will take a different height field to achieve the "inverse" effect.. I have tried it before but do not quite like the result.. IMHO, the PS Lighting effects did it more "politically correct". If you press the "inverse bumpmap" there, the effect is different from the "Invert" Bump Map in Gimp.. Just try it out yourself and see if you agree... don't ask me to explain, I can't .. ;-) re, lasm gallery -> http://gug.sunsite.dk/gallery.php?artist=41 --- In [EMAIL PROTECTED], Jens Lautenbacher <[EMAIL PROTECTED]> wrote: > On 28 Jan 2001 17:20:39 +0100, Rebecca J.

I still don't see what this is about. the bumpmap layer used internally in the case of a non graya layer is still only the grayscale value of the layer. color inverting the bm-layer and using this result as the bm may produce something, but why should this be more correct than using the "invert" button in the bm plugin? but maybe I just don't understand what you want to do correctly. jtl
