[osg-users] Re?? how to get the real world coordinates(x, y,z) in shader

Sorry for my English.I meant that those two coords should be corresponding to a single coordinate system, either local coord system or world coord system or view coord system would be ok-- Original -- From: "Solkar Graphics" Date: Wed, Jul 9, 2014 05:49 PM To: "osg

Re: [osg-users] Programming model for layers above and below the SG

Hi Solkar Graphics, Please forgive my curiousity, I really wonder what you want to build and I'm pretty new to the OSG library. Along with that, your question has aroused couple of question in my mind, I'll appreciate if you express your comments and opinion. Bcoz in cases where I don't understa

[osg-users] osg::notify + \n does not work

Hi Robert & all, When I run the program below I only see notice 2+3. When I uncomment the 4th notice they all appear but in order 2314. So it seems that osg::notify waits for a std::endl to flush, but shouldn't \n do the job as well? (I am on xubuntu 12.04, OSG 3.0.1, OSG_NOTIFY_LEVEL=NOTICE) Th

Re: [osg-users] Access vertexes of a 3D model in the vertex shader

Hi Sebastian, At first I transformed from the camera coordinate system [Xc,Yc,Zc] to the pinhole image projecting system [X=Xc/Zc, Y=Yc/Zc]. Then the distorting is processed based [X,Y]. At last, the projection matrix is mutiplied and the pixel coordinate is getten in this way. Since the input

Re: [osg-users] Access vertexes of a 3D model in the vertex shader

Hello, Could you tell me what do you mean "define a mapping from vertex numbers to st coordinate"? Could I do like this in the fragment shader? gl_TexCoord[0].st = vec2(position.x, position.y); gl_FragColor = texture2D(myTexture, gl_TexCoord[0].st); where position is the distorted pixel coordi

Re: [osg-users] Apple Retina Display Not Perfect

Hi Michael, I wouldn't imagine osgEarth is causing the issue. I'd try running just a regular OSG application and see if it has the same issue just to be sure though. Jason On Tue, Jul 8, 2014 at 6:59 PM, Michael Rice wrote: > Hi, > > I'm using OSG 3.3.2, osgEarth 2.5.0, and Qt 5.3.0 on OS X
