Re: [osg-users] Geographic earth in OSG?

Hi Shayne and Akilan, I suspect your problem has something to do with your shape drawable where you're using a sphere in your code. That is what I was trying to say, If you do your calculations with an ellipsoid model, but then you try to draw these positions in a ShapeDrawable::Sphere you'll

Hi Thomas, I have been a bit busy these days, but hopefully this weekend I will be able to take up again the web tasks. I will start to write the author's guide ASAP, we can modify it later if necessary. Cheers. 2012/5/17 Thomas Hogarth thomas.hoga...@gmail.com Hi Again I've started work

Re: [osg-users] Render a sub part of the viewport

Hi Aurelien, What you need to do is set up your RTT Camera so it's dimensions are 9x9 (viewport and texture sizes), keep the view matrix the same as the main camera, then adjust the post multiple the projection of the main camera so that it captures just the required portion of the main window.

Re: [osg-users] Render a sub part of the viewport

Hi, Thanks for your guidelines, this is exactly what I try to do... no sucess for the moment but it's probably just a math issue with the projection matrix modification. Another question : how can I render only this camera ? (not the main one) I tried to modify cameras node masks so when I

Re: [osg-users] Render a sub part of the viewport

Hi, Aurelien This can be done with viewport modification. Viewport matrix is one that transform -1...1 postperspective coords to window coords. You should attach 9x9 image\texture to camera, and set camera viewport with x,y = (window mouse coords center transformed to screen coords in pixels -

Re: [osg-users] Render a sub part of the viewport

Replying to myself :) In this case you should attach full sized texture, but only 9x9 pixels area around mouse cursor will be drawn. Another possibility is to attach 9x9 texture, keep viewport (0,0,9,9) and tweak projection matrix with scale and translate, as Robert already said. 18.05.2012,

Re: [osg-users] Render a sub part of the viewport

This is not exactly what you want, but something similar: you can rework your rendering process to use 3 cameras: 1) RTT camera which render scene. 2) your 9x9 RTT camera. 3) main camera (which output stuff to framebuffer) - this one just render full screen quad with texture from first camera.

[osg-users] Help: how does lightSource with referenceFrame of osg::LightSource::ABSOLUTE_RF work?

Hello, I have 2 questions about the lightSource node. (1) Does lightSource affect all the geode nodes in the scenedata or only the ones that are under it in the sceneData structure? (2) In my application, a lightSource is attached to the main sceneNode, and this lightSource has a osg::group

Re: [osg-users] Geographic earth in OSG?

I understand the discrepancy. The real question is why the originator of the thread was using a sphere in the first place and not the ellipsoid to place the models... -Shayne -Original Message- From: osg-users-boun...@lists.openscenegraph.org
