| | | (...) Ok, I had a little time over the weekend to spend with the Red book, and I think I may have it now. Hopefully not too late to make it into LDView version 3.0 RC 2. ;^) So to eliminate the halo, what we want to put around the image edges of the (...) (19 years ago, 20-Jun-05, to lugnet.cad)

| | | | | (If you haven't read Don's message, go do that now. It's too long to quote here.) I have a few comments. The first is that it will only fully work if you set the line width to 2 or more. Otherwise, you'll have jaggies around the inside edges of the (...) (19 years ago, 20-Jun-05, to lugnet.cad)

| | | | | | (...) And I'm not sure I understand what you're saying about the linewidths. :^) I use glPolygonOffset to make sure the lines get drawn over the polygons underneath. (Plus I cheat a bit and add a bit more z to antialiased edge lines so even skinny (...) (19 years ago, 20-Jun-05, to lugnet.cad)

| | | | | | (...) Well, as you point out below, I was mostly wrong. However, I suspect it will still produce jaggies on the inside edge of the lines (but I could be wrong). These would almost certainly go away with 2-pixel edge lines. (These things are very (...) (19 years ago, 21-Jun-05, to lugnet.cad)

| | | | (...) Well, it's certainly long past LDView 3.0 RC 2, but I did finally come back to this. After spending a few hours getting nice alpha data into the image file for transparent parts, I realized that the same set of steps would probably work for (...)

| | | | (...) I forgot to mention, but while the above page looks very similar to the page I posted recently on a lugnet.cad.ray thread, it is different in a very important way. The image on the above page was saved out of LDView at 800x600, which is the (...) (17 years ago, 10-Oct-07, to lugnet.cad, FTX)

| | | | (...) Hey those look nice. Just for kicks I ran off a test with the ancient method of ldglite at 2x scale followed by ImageMagick mogrify 50% to shrink it back and antialias. (URL) I like your edge outer edges better. Very nice. I'll have to look (...) (17 years ago, 10-Oct-07, to lugnet.cad, FTX)

| | | | (...) The image on the above page was rendered with antialiased lines, but no FSAA. FSAA would have brought the halo back, since there's no way to have FSAA on part of the scene, but not on other parts. In theory I could render the image twice, once (...)

Does the SMOOTH HINT make a big difference? I think I set it to (...) (17 years ago, 10-Oct-07, to lugnet.cad, FTX)

My ATI at work does a reasonably good job with the same settings, but it leaves a few small gaps in the edges (around some studs): (URL) (...) Actually, based on this you'd (...)

To my eye, it's more blurry when set to NICEST: (URL) The difference is best seen by loading both images in separate tabs of (...) (17 years ago, 10-Oct-07, to lugnet.cad, FTX)
