Name : opencsg Product : Fedora 43 Version : 1.8.2 Release : 1.fc43 URL : https://www.opencsg.org/ Summary : Library for Constructive Solid Geometry using OpenGL Description : OpenCSG is a library that does image-based CSG rendering using OpenGL. CSG is short for Constructive Solid Geometry and denotes an approach to model complex 3D-shapes using simpler ones. I.e., two shapes can be combined by taking the union of them, by intersecting them, or by subtracting one shape of the other. The most basic shapes, which are not result of such a CSG operation, are called primitives. Primitives must be solid, i.e., they must have a clearly defined interior and exterior. By construction, a CSG shape is also solid then. Image-based CSG rendering (also z-buffer CSG rendering) is a term that denotes algorithms for rendering CSG shapes without an explicit calculation of the geometric boundary of a CSG shape. Such algorithms use frame-buffer settings of the graphics hardware, e.g., the depth and stencil buffer, to compose CSG shapes. OpenCSG implements a variety of those algorithms, namely the Goldfeather algorithm and the SCS algorithm, both of them in several variants. -------------------------------------------------------------------------------- Update Information: OpenCSG 1.8.2 release with rendering fixes for Linux with Nouveau driver. The new release fixes a z-fighting bug in the SCS algorithm, that was known for a long time, under Linux with Nouveau graphics driver. -------------------------------------------------------------------------------- ChangeLog: * Mon Feb 9 2026 Lumir Balhar <[email protected]> - 1.8.2-1 - Update to 1.8.2 (rhbz#2437637) * Fri Jan 16 2026 Fedora Release Engineering <[email protected]> - 1.8.1-3 - Rebuilt for https://fedoraproject.org/wiki/Fedora_44_Mass_Rebuild -------------------------------------------------------------------------------- References: [ 1 ] Bug #2437637 - opencsg-1.8.2 is available https://bugzilla.redhat.com/show_bug.cgi?id=2437637 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
