The env variable doesn't help. I see such errors: With subloading enabled i see this: before Glyph::subload(): detected OpenGL error: invalid enumerant Glyph::subload(): texture sub-image width and/or height of 0, ignoring operation. I've posted the log on the github issue. Remo

Without this setting I see only a blue screen/window without any text. Remo -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=70491#70491 ___ osg-users mailing list osg-users@lists.openscenegraph.org

Re: [osg-users] How to disable Antialiasing of an osg::Text

Hi Lv, It looks like you are position the text in a 3D scene and leaving it to scale in object coordinates, which is fine, but it does mean that the scale will and orientation will vary, this is very different challenge for rendering clear text than rendering a fixed font to a fixed 2D projection

Nice. Where can we get the game? 2017-03-10 3:25 GMT+07:00 Johny Canes : > Hi, > > Hey, here's a screenshot of my game. I've ported it from Three.js and OSG > has been a really, really smooth ride so far! > > That's an Awesomium texture on that CRT :D! > >

Re: [osg-users] bounding box collisions (without osgbullet)

Hi Sebastian If you have few dynamic objects, an update callback with an inner intersectvisitor can do the trick ... In other case you may have to reimplement the wheel (like a AABB sweeping broaphase) , so osgBullet seams the best fit And to finish, if you have massive dynamics: -bullet3

Re: [osg-users] Frame Rate

HI Bhanu, Have a look at the osgforest example, it has various approach to rendering large numbers of trees. The example uses texture quads as the basis but the approaches can be generalized. Robert. On 14 March 2017 at 05:40, Bhanu Chandra wrote: > Hi, > I am trying
