Hi. * Cross-platform support. In short, OpenSceneGraph runs everywhere with only a bit of configuration. I currently work on the cross-platform guide for OpenSceneGraph to cover major platforms: https://github.com/OGStudio/openscenegraph-cross-platform-guide
* Embedding. OSG-Qt integration works on all desktops (I have not checked other platforms). * Back-end. There are rumors that Vulkan driven scene graph may appear in the future. * OpenGL deprecation. Apple is actively pushing Swift, but Swift still has no stable ABI and most of Apple's own software is still in Objective-C. I'm sure OpenGL is here to stay for at least a decade. 2017-06-23 5:33 GMT+07:00 Andy Somogyi <[email protected]>: > Hi All, > > We're evaluating using OSG as a possible graphics backend for our real-time > physics simulation project, and I've got a few questions: > > * We suport Mac, Windows and Linux, how good is cross-platform support with > OSG? > > * It looks like it’s pretty easy is it to hook up Magnum to an existing > native window, just would like to confirm.
