(...) For transparency, LDView sorts triangles, and only triangles, not parts. So the centroid of each triangle is (p1 + p2 + p3) * (1/3). All transparent geometry in the whole model goes into one big list of triangles. While I'm at it, I calculate (...) (15 years ago, 31-Mar-10, to lugnet.cad.dev, FTX)

--snip-- (...) Out of interest which centroid do you use? I would have thought that the bounding box center was better than the centre of all corner points (since these cluster around areas of high detail) but you've presumably tried different (...) (15 years ago, 31-Mar-10, to lugnet.cad, FTX)

(...) If you prefer not to sort at all you can use glEnable(GL_POLYGON_STIPPLE) for transparent polygons. It doesn't look nearly as good, but it's really easy to code. Have fun, Don (15 years ago, 31-Mar-10, to lugnet.cad, FTX)

(...) The only polygons that LDView sorts are transparent ones. Everything else is handled by the OpenGL depth buffer (glEnable(GL_DEPTH_TEST), followed by glDepthFunc(GL_LEQUAL)). Transparent polygons need to be sorted before being drawn, and (...) (15 years ago, 31-Mar-10, to lugnet.cad, FTX)

(...) I have fixed that problem. It has been in the xmpd.dll version 2.2.1. Now version 2.2.2 is in the download package at (URL) and detecting double lines is working again. Sorry for that trouble. cu mikeheide (15 years ago, 31-Mar-10, to lugnet.cad)

(...) The polygons have to be painted on the screen in the correct order in order to have the part displayed correctly. It's not handled automatically. So I need an algorithm to sort the polygons.. and my current one doesn't work right. -Santeri (15 years ago, 31-Mar-10, to lugnet.cad, FTX)

Hi folks, over the latter half of the year 2009 I've been planning and experimenting on the thought of a good CAD program for part authors. Now I'm unveiling my thoughts to the public, but this is not an announcement. It's too early for such. (...) (15 years ago, 31-Mar-10, to lugnet.cad, FTX)
