Re: [osg-users] Projective Texturing in GLSL shader

Hi Paul, In the vertex shader try this vec4 ecPosition = gl_Vertex * gl_ModelViewMatrix; gl_TexCoord[0].s = dot(ecPosition, gl_EyePlaneS[0]) ; gl_TexCoord[0].t = dot(ecPosition, gl_EyePlaneT[0]) ; gl_TexCoord[0].p = dot(ecPosition, gl_EyePlaneR[0]); gl_TexCoord[0].q =

Re: [osg-users] databasepager new node inserted callback???

Re: [osg-users] EllipsoidModel funtion parameters units

Hi Nicolas, Just a quick question: The latitude and longitude parameters of convertLatLongHeightToXYZ are in radians, and the rest of parameters in meters? This is correct. To help in future I've added clarification of units into the doxygen docs of EllipsoidModel. Robert.

Re: [osg-users] problem when using multi-sceneview in 2.3

Hi Wangmiao, Using multiple SceneViews does work in 2.x, osgViewer uses SceneViews under the hood to implement rendering, and it supports multiple views across one or more graphics context without any problems. As to why things are working your app I can't really even have a guess at as I don't

[osg-users] Feedback sought on osgViewer swap ready support for clusters

Re: [osg-users] How to disable culling of a node

Hi Emilio, the near clipping plane defines the border between things that are in front or behind you (resp. the camera). Since you cannot see what is behind you, I should expect that deactivating the clipping will not accomplish what you're looking for. If you want to see more of the ship

Re: [osg-users] How to disable culling of a node

Hi Joachim, It's true, I can set the clipping plane nearer to me. But then I get z-fighting effects in my scene, due to loss of precision in depth buffer when near plane is close to 0.0 (and far plane has a high value due to the size of my landscape). Kind regards, Emilio. 2008/4/14, Joachim E.

Re: [osg-users] How to disable culling of a node

Hi Emilio, I think the best way to achieve what you want is to render your scene using two osg::Camera (two pass), first render your scene and then render the object you want to be in the first plane. Each camera have it's own near/far clip planes. Cheers, On Mon, Apr 14, 2008 at 3:06 PM,

Hi Marco, Thanks for the link. I've run through it quickly but other than a listing of extensions there isn't an actual coding example showing how they are used. I can make educated guess for most of them, but not enough to know exactly how they should be used in the context of osgViewer - it

Hi Judia, What you are trying to do should work, but without the code for setting the different stateset to the appropriate nodes I can't say what exactly the problem is. The fact that you refer to NodeCParent looks suspect, you should apply directly to NodeC as NodeCParent is NodeA... Robert.
