Any of my OSG homies do anything with Nvidia RTX yet? I did a simple search and didn't see any overlap between OSG and RTX. ___ osg-users mailing list osg-users@lists.openscenegraph.org

Re: [osg-users] Question about security of shader developments

You could obfuscate and minify your shader: https://github.com/laurentlb/Shader_Minifier Or hire a demoscene person to mangle it. ;) On Thu, Jan 31, 2019 at 11:43 AM Werner Modenbach wrote: > Hi Michael and all other people responding to my request, > > first of all thank you very much! > >

Core profile has none of the backward compatibility features: https://www.khronos.org/opengl/wiki/OpenGL_Context#OpenGL_3.2_and_Profiles I'm guessing you won't have much luck getting your application to work in that limited situation. ___ osg-users

Re: [osg-users] EXTERNAL: Re: Where is CreateContextAttribs() being used?

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] Volume Rendering and Depth Buffer

Just out of curiousity, what are you volume rendering and what are your requirements? We did some interesting volume rendering work a few years ago for Iowa State University's Ames Lab. On Mon, Apr 15, 2019 at 1:08 PM Anna Osvin wrote: > Hi. In a project that I'm working on I have an

Instead of reading Z depth values, can you simply run an intersection of the click ray-vector against the model data (polygonal and volumetric) when they click to place markdown points? On Mon, Apr 15, 2019 at 2:34 PM Anna Osvin wrote: > We are working on medical software for Dentists. We need

Re: [osg-users] How to implement a Laser Simulation?

Is this like a scanning sweep laser beam? I'd model it as a triangular frustum with a texture on it generated by a shader with some kind of animated fBm (Fractal Brownian Motion) noise. Is this a work project or school or what? On Fri, May 24, 2019 at 7:35 PM Matheus Santos wrote: > Hi, I

Re: [osg-users] Huge perfomance issues

I think I'd create a single object to represent ALL of the objects of a given class, eg Lines, PolygonLines, Rectangles, etc. Set this up to use buffer objects and it will refer to the buffer object to fetch the vertices, indices, and possibly attributes for the appearance. Then on each frame

Re: [osg-users] Resolution of .earth vice .osg/.ive Formats?

It sounds like osgdem's idea of 'levels' may not correspond to CDB's, and increasing the number os osgdem levels may be the right solution. I don't think osgdem ever generates "too many" levels -- the "levels" option simply limits how far it is allowed to go. So, if you really want ALL detail
