Re: [osg-users] OSG Ellipsoid to Sphere Conversion

Hi, Not sure if this helps but I believe you may define own Ellipsoid with EllipsoidModel. Just define it with both Radii the same and voila you have the sphere ... Cheers, Wojtek Lewandowski 2016-09-26 23:54 GMT+02:00 Sebastian Messerschmidt < sebastian.messerschm...@gmx.de>: > Hi Inna, > >

Re: [osg-users] OSG Ellipsoid to Sphere Conversion

Hi Inna, It still doesn't make a lot of sense, The ellipsoid model is to abstract geographic coordinates to geocentric coords. Lat, long however is spherical coordinates and can be mapped to an ellipsoid... So please try to rephrase your question: What is it what you want to do, or present

Hi Mr. Robert, Thanks for the reply. Sorry , Seems I explained very badly . Well , my issue is that I want to make sphere and text on it. I was able to do with the EllipsoidModel and using log , lat and height. I want to do the same with same Sphere. But I dont have idea how to do with

When reviewing doing a code review of the affinity code in OpenThreads today I noticed that OpenThreads doesn't fully expose all the functionality available for setting or resetting the thread affinity, as OpenThrreads just allowed you to specify a single cpu number for a thread to have affinity

Hi Inna, You don't say what you've tried, only that you tried something relating changing from EllipsoidModel to Sphere, you don't say what you changed the code to, what the result you got. Without knowing what you are specifically having a problem with we can't start helping you achieve what

Re: [osg-users] OSG Running with modern OpenGL

Thanks Chris, OSG earth does have some fixes for materials and lighting, but it would be cleaner if it was part of OSG core. I'm pursing those as well, just seems like the core libraries should function out of the box, without spending a week applying patches or workarounds. We've been pursing

I think looking at the osgblenddrawbuffers or osgmultiplerendertargets might be a good start. Neither of these are really doing what you are aiming for, but shows you how to add the color buffers and shaders. You might also look at the OSGPPU project. It I think it has some more relevant

Hi Gianni, One question, why should I use a "vertex" shader/attribute when I need to colour a triangle uniformly? Long story short: There is no such thing as per-primitive colors. Long story long: In order to color your primitives you need to assign a color to each vertex. That is how modern
