 | | Line Thickness and Antialiasing in LdGLite 0.7.3
|
|
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"! (...) (24 years ago, 27-Dec-00, to lugnet.cad, lugnet.cad.dev)

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)

(...) Yeah, it's been that way for a while. Perhaps forever. I've fiddled with various ways to fix it, but haven't yet come up with anything that made me happy.

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)
