Re: [osg-users] play animation backwards?

Hi Paul, Thank your for your suggestion. Decrementing the simulation time in Viewer::frame() would probably allow to play one animation backwards. But I would be stuck if I wanted to play two different animations at the same time, one being played backwards and one in the normal direction?

I used Collada dom 2.4. But in OSG WiKi: As of December 2011, testing indicates that the plugin still does not work with the COLLADA DOM version 2.3.x, but does work with the 2.2. With COLLADA DOM version 2.2. it works fine (almost :D ) In ..\src\osgPlugins\dae\daeWSceneObjects.cpp we

Hi, I successfully compiled OSG for Android on Windows using the nice tutorial from this forum ([Tutorial] Building osgAndroidExampleGLES1/2 on Ubuntu 11.10). The example runs pretty well (especially if you ignore everything Eclipse says). My problem is that my 3D Model dissapears from the

[osg-users] [forum] How to acquire the current location information of a drawable object? And how to calculate the distance between an object and the viewpoint?

Hi all, I'm quite new to OSG and have no OPENGL background. I want to know how to acquire the current location information of a drawable object? Actually the initial position of the geometry is set by me. But when I move the objects with mouse, the spatial information changes, right? So I want

Re: [osg-users] OSGAndroidExample - 3D model disappears when device goes to sleep

Nah, it's just it's default behaviour. Every time the context is regenerated (open application, change screen orientation, go to desktop and resume, etc) it creates again the viewer for the new conditions and the scene is emptied. It's a toy example and there are a lot of cases that have to be

[osg-users] Issue adding transparency to a simple model

Hi. I have a simple model I wanted to apply transparency to. I load the model data into a geometry node, and set my scene up. To get a transparent effect, I apply an alpha value to gl_FragColor in my fragment shader. The shaders are trivial: Vertex: void main() { gl_Position =

Re: [osg-users] Issue adding transparency to a simple model

If you're unable to decompose your con-convex model into convex components, then you'll need an order-independent solution such as depth peeling. One possible implementation of depth peeling in OSG is demonstrated with the osgoit example. -Paul On 7/3/2012 3:10 PM, Preet wrote: On Tue,

You have to enable blending. Try this: [code] ss-setRenderingHint(osg::StateSet::TRANSPARENT_BIN); ss-setMode(GL_BLEND,osg::StateAttribute::OVERRIDE | osg::StateAttribute::PROTECTED | osg::StateAttribute::ON); [/code] Thank
