(...) Thanks! I had already discovered DAVID through your website. I got a line laser from dealextreme too, but I didn't have much luck using the video on a digital camera instead of a webcam. I'll try more later! Sculptris looks very cool. It looks (...) (14 years ago, 29-Sep-10, to lugnet.cad.dev, FTX)

The free version is perfectly usable (but you'll need Meshlab to assemble the scans in a single mesh). A (...) (14 years ago, 29-Sep-10, to lugnet.cad.dev, FTX)

Hi Bram, Looks stunning. Downloading now! Now if I could find some more time for LEGO I could actually build the horse I sculpted with the earlier version of LSculpt. (URL) Jaco (14 years ago, 29-Sep-10, to lugnet.cad.dev, FTX)

(...) Hmmm, it seems to me that any algorithm that can find the missing Type 5 lines (in order to create the dummy entries) should be able to find *all* of the Type 5 lines. Some missing lines is just a special case of all missing. So just include (...) (14 years ago, 23-Sep-10, to lugnet.cad.dev.org.ldraw)

(...) Actually, no. That is indeed a long-term goal, but it is hampered by two things. First of all, it's a lot of work. Secondly, the current algorithm is actually useful to part authors, since it can visually highlight missing conditional lines. (...) (14 years ago, 23-Sep-10, to lugnet.cad.dev.org.ldraw)

(...) I see. So what you really want to do in LDView is ignore the Type 5 lines (at least for smoothing) and smooth wherever there's no Type 2 edge lines between the triangles (and quads). (...)

The problem is that two co-planar triangles sitting next to each other (...) (14 years ago, 21-Sep-10, to lugnet.cad.dev.org.ldraw)
