Re: [pygame] opengl from python - drawing wireframe shape colours and contour in the same time
You can draw wireframes instead of fills by setting: glPolygonMode(GL_FRONT_AND_BACK, GL_LINE) Then draw your geometry as desired. Note this has the same limitations and drawbacks as GL_LINE, but for simulating old-school vector graphics it works pretty good. You can control whether or not a particular edge is drawn using edge flags. That way interior edges that exist just for tessellation, don't clutter up the rendering. What typically looks good is to do a first pass at low alpha with a wide glLineWidth, then render again with a higher alpha and a lower width. Last draw with line width set to 1 (or whatever) and full alpha. Gives a decent glowing vector line effect. Also be sure to enable multisampling to combat aliasing. I attached a screenshot of a model rendered using this technique. The code that produced it can be found here: http://code.google.com/p/caseman/source/browse/trunk/eos/tools/show_obj.py <> The libraries it uses to load the model and draw it are there as well. hth, -Casey On Jul 27, 2009, at 2:06 PM, Paulo Silva wrote: no, my idea is doing simple poly games, a bit like those 3d games from Amiga time (such as Robocop3 and many others) - very flatcoloured - but i really wanted so have the meshes wireframed - thanks for all useful info! :) On 7/27/09, Ian Mallett wrote: Yes, unfortunately.

otherwise, it's extremelly important Pygame being plenty of small snippets, and having them on places like wiki or www.pygame.org/docs/ is extremelly important, specially for newbies like me On 7/27/09, Paulo Silva wrote: > i don't know... maybe Pete Shinners? > > On 7/27/09, Horst JENS wrote: >> Am Sonntag, den 26.07.2009, 22:06 +0100 schrieb Paulo Silva: >>> would be great if we can notify them for the administrator removing >>> them - if we allow anyone to remove everything, the same spammers may >>> wish to remove very useful information we waste our precious time on >>> posting them... >> >> who is the official wiki admin to notify ? >> >> -Horst >> >> >> -- >> Horst JENS >> horst.j...@chello.at >> http://members.chello.at/horst.jens >> >> >

Yes, unfortunately. That may be a problem, especially if the object is high poly. There are more complex methods that use shaders.

thanks! (pressuposed i understood the same object must be drawn twice, as shape and as wireframe?)

[pygame] opengl from python - drawing wireframe shape colours and contour in the same time
hi! do someone know how can we draw opengl shapes with plain colour fill and outline, with different colours, at same time? a good example is what were used on the Area 4 of Rez: http://www.youtube.com/watch?v=aAncDNDsv7s , and some games from Kenta Cho (which also uses OpenGL) (sorry posting this message at pygame mailing list as well, maybe there are good audience can answer, and thanks in advance too) thanks!
Re: [pygame] write gif animation?
I used to make movies from my PyGame applications by using pygame.image.save(...)--or sometimes the OpenGL equivalent--to save to a file. I then imported these into Animation Shop Pro (an old version ~1999) and saved as a .gif or .avi. I definitely think a .gif animation file creator would be an excellent addition to PyGame...
Re: [pygame] write gif animation?
would be a good idea capturing each frame into a file, and joining all externally with gifsicle from a command line shell call? i used to do it a lot on sdlBasic, and surelly it will work on pygame...

Re: [pygame] write gif animation?
Hi Jake, Either install PIL for Python2.5, if possible, or use an other external software. I use imageMagick a lot. The command-line executable is called "convert". See the online doc for how to use it. I personnally use Twisted for handled subprocesses... but you could use subprocess or os.system. a 2009/7/27 Jake b : > What's the best way to convert to a gif animation?

[pygame] write gif animation?
What's the best way to convert to a gif animation? I have a list of Surfaces, that I will use as each frame. Searching, it looked like PIL is the answer, but the installer requires python 2.2, while I have 2.5. -- Jake
