OpenGL integerated wtih Squeak IDE
by Lawson English 06 Jan '12

06 Jan '12

This is a very poor attempt to do what Matt Fulmer did with OpenCobalt: integrate overlapping Morphic windows with OpenGL. The only advantage is that it doesn't require OpenCobalt. https://www.youtube.com/watch?v=Ctm-Q39nd-k The entire World is being rendered onto an OpenGL texture which is updated with every tick. With the proper scaling , the destop could be repositioned along the z access at any point within the fustrum and still keep the default mouse handling. Add mouse handling from OpenGL itself, and you can have 2D widgets projected onto 3D objects, not to mention 3D widgets fully integrated with the Squeak desktop. Time to revive/revitalize Balloon3D, perhaps? Whatever happened to 3D Morphic? There's obviously a great deal of room for optimization, and of course, the sky is the limit for what could be done in terms of lighting, materials, etc. Using more modern APIs of OpenGL (I'm using immediate mode! (!) and only stuff from the first 6 NeHe tutorials) one could have an awful lot of interesting stuff going on. Lawson

mailing lists restored

05 Jan '12

If you get this message, the mailing lists have been restored. However, anything that was sent in the past 48 hours is almost certainly *lost*, and would have bounced back to the sender. Please resend. The board takes this outage seriously, and will be taking action to ensure that it won't repeat. Well, not precisely the same way, anyway. :) Also, in part, blame SOPA and GoDaddy, which triggered some nameservice changes at the last minute. -- Randal L.

FFI/linux dynamic library load order?
by Hans-Martin Mosner 05 Jan '12

05 Jan '12

Hello, after some wasted hours tracking down why my OpenGL code does not work at all, I found that Squeak probably loaded the wrong GL.so library - instead of /usr/lib/nvidia-current/libGL.so it loaded /usr/lib/i386-linux-gnu/mesa/libGL.so. C programs compiled with -lGL use the correct library, of course. Does anyone have an idea what causes this confusing behavior, and what can be done to fix it? BTW, my VM is the Cog 3.9-7 VM - when I try the 4.0-2522 Cog VM, the module "X11" can't be found, possibly because naming conventions changed somewhere? Cheers, Hans-Martin
