LdGLite version 0.7.3 in now available. With all the talk about line widths and antialiasing around here lately I decided to add it to ldglite. Heck, it only took about an hour to make the changes. As Lars recently proclaimed, "Hooray for OpenGL"! Actually I discovered a segfault introduced by my double buffered spin mode code in the Mesa flavor of ldglite 0.7.2 and had to roll a new release anyhow. I guess the one linux user didn't notice the problem during the brief lifespan of that version. ;^) I also finally got around to fixing a few nagging case sensitive filename problems in the L3 parser. Lars if you're reading this, I added a few more #ifdef OPENGL lines to the version of L3Input.cpp in l3glite. Are we still trying to keep that file in sync? Get it at the mirror site: http://www.geocities.com/dheyse Scroll down for a sample image with antialiasing and linewidth set to 2.5. Enjoy, Don (One of these days I'm gonna have to figure out why SCP to the main site at the SourceForge no longer seems to work.)

I've tested LdGLite 0.7.3 on Linux, and the line width option worked fine! Thanks! While rendering a model with steps, I noticed that the whole image is rerendered at each step. Is this normal? I don't remember right now if the same thing happened (...) (24 years ago, 29-Dec-00, to lugnet.cad, lugnet.cad.dev)

Very cool! I noticed two things, which could be considered problems. One is straight-forward, the other is not so. The first thing is that using the -ms commandline option doesn't save any images if there are no 0 STEP commands in the file. I was (...) (23 years ago, 2-Jan-01, to lugnet.cad, lugnet.cad.dev)
