This was apparently due to an incompatibility of the fragment program with the fixed function pipeline us= ed at the vertex stage. OpenCSG 1.4.1 implements a workaround: a vertex progra= m is now used instead. I hope that the rendering bugs on Intel graphics hardware= are now really a thing of the past. 15-Sep-2014: OpenCSG 1.4.0 released OpenCSG 1.4.0 contains a bug fix for rendering CSG expressions with more th= an 255 primitives. For the layered Goldfeather algorithm, this number of primitives could cause an endless loop before. In the case of the SCS algorithm, there were rendering errors with older versions. For the SCS algorithm, the fix contains a new rendering path: using a fragm= ent program, a kind of alpha test is performed based on all the components (r, = g, b, a) of a fragment. This allows, in theory, to distinguish 2^32 - 1 primit= ives instead of 2^8 - 1 before. This new rendering path should be, in theory, al= so more stable than the old one, and some rendering problems reported for Intel graphics hardware might be solved with the new version. 11-May-2014: OpenCSG 1.3.3 released OpenCSG 1.3.3 is a maintenance release, providing minor portability improvements and bug fixes. In particular, OpenCSG should now compile out-of-the-box on Linux x64 systems. ______ While here also pet portlint and add a license: It's GPLv2. BTW, there is an exception clause for cgal (which I didn't account for). --=20 You are receiving this mail because: You are the assignee for the bug.=
