[osg-users] RTT and Shaders using vertex attribute aliasing

Hi all, I have a simple RTT setup. works great but when I setup OSG to turn on the vertex attribute aliasing and allow OSG to provide gl_ inputs via the osg_ prefix my shader breaks. No errors. Can't even get a red colour on my test quad. Can anyone see what I'm doing wrong? Can I still use

[osg-users] Creating depth texture in pre render pass and using it in final rendering

Hi all. I'm working on converting my application to deferred rendering. Due to the complexity of the fragment shaders I'm not able to precalculate everything necessary for the fragment shader into textures. Some time ago I found an example of calculating the depth texture in a simple pre

Re: [osg-users] [forum] How to make isometric view

Thank you Robert for your answer. Sometimes things seem to be very simple but when you are beginner, you miss details. It seem not to be enough to use the setViewMatrixAsLookAt() because I used setCameraManipulator(new osgGA::TrackballManipulator). I must used this : Code:

Thanks Richard, Jan, indeed, there is a lot of research to be done for this. I have done some consultancy in of the the CS UNI in Macedonia with teachers who tried this in the past so there are already some insights. I would see the first simple app on mobile device, something like an app that

Re: [osg-users] Intergration with QT

Dear Robert, I am examining the oshhud and osgQt examples for 3 days. I also know that only depth buffer is required for osg hud example. I know. But when merge osg hud example with osg qt example it does not work. To get rid of this, I have cleared color buffer there. But in

[osg-users] View coordinates of a 3D point

Dear OSG forum, Knowing the 3D coordinates of a point, is there an easy way in OSG to compute its 2D projected equivalent (i.e. in pixel coordinates)? Thanks, Antoine. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=73112#73112

[osg-users] Preparing to tag the OpenSceneGraph-3.5.10 dev release

Hi All, I am planning to make the 3.5.10 developer release later today, or perhaps over the weekend. I'd appreciate testing of OSG master on the platforms that you have available. I have also cleared quit a bit of the reported issues and merged most the backlog of submissions so I'm pretty

[osg-users] Qt OsgEarth HudCamera Composition

Hi, I can not see hud camera text. I only see main camera output which is generated by osg Earth manipulator. This problem comes up with integration with Qt. Before integrating with Qt, this derived hud view example works great. I am sharing a sample of code. What is the reason that I could

I have set clear mask for hud camera GL_COLOR_BUFFER_BIT in addition to GL_DEPTH_BUFFER_BIT. The problem was solved. aozdin wrote: > Hi Robert, > > Firstly, I am grateful for your quick reply. > > I intend to have a 3D view that is overlay by the Orthographic view as a HUD. > That is right.

Hi, I'm trying to figure out how to render my scene as an isometric view. I have not found a complete example. I have some boxes in my scene, so I compute the bounding box of the root node an using "getCamera()->setViewMatrixAsLookAt(eye, center, up) but it is not really orthogonal. Can someone

Re: [osg-users] osg::Operation

Hi Adrian, The OpenSceneGraph/examples/osgtext example has a code path that includes use of UpdateOperation in the context of multi-threaded operation. If you run: osgtext --mt You will seem a continuous random placement of osgText::Text labels into a box using a custom osg::Operation in
