This is correct. If your application is GL3 context compatible, you can create a GL3 context and then RenderDoc should be happier. On Thu, Apr 11, 2019 at 3:08 PM Lionel Lagarde wrote: > Hi, > > Win32 is the name for all the Windows windowing systems. It is used on all > Windows (XP, 7, 10...)

Re: [osg-users] osgSim::DOFTransform pivot point

2019-04-10 Thread Chris Hanson
Honestly, it sounds like a modeling problem. What format was the aircraft model originally in? Your best bet is probably to load it into a modeling tool, fix up the origin/pivot points in that environment and resave the model. It's not really specific to OSG at all.

This usually means the plugin was not found or failed to load. Can you trace with something like SysInternals tools and see if the DLL file is found and what other dependency files it might have tried to load? On Mon, Apr 8, 2019 at 5:50 PM Nikita Petrov wrote: > Hi, > > I am trying to build

Well, I was wondering if there was an OpenGL RTX API anywhere, but it doesn't seem there is. Vulkan would appear to be the way to go for the future, but since that's not ready for the oven yet (don't even have all the mise en place), it might be we just have to make a utility library to shovel

So, all OSG state (including Uniforms) are managed in a hierarchical manner, with override rules. So, you can select a section of the graph and designate all of it to have Uniforms defining transparency and all of the scene below that Uniform state will have those Uniforms applied and be

Normally I'd do this with some kind of shader and a Uniform to control the transparency. If you haven't seen it already, I'd take a look at this set of code we did for a client a few years ago: http://alphapixel.com/project/osg-transparency-toolkit/ It was made for large complex CAD scenes
