Hi Aruna,
What I do to pause the "game loop" is pass an own controlled
simulationTime to the frame call method.
Something like:
double simulationTime;
osg::Timer timer;
osg::Timer::timer_t startTick;
bool pause;
void pause()
{
pause = !pause;
if(pause)
startTick = timer.tick();
Hi,
...
How can I pause the game loop in osg? Can any 1 help?
Thank you!
Cheers,
Aruna

Hi Michael,
As far as I can see to implement a solution I'll have to duplicate a lot
of code from RenderStage/RenderBin, unless you can see a more elegant
solution?
A simple way could be to run two viewers, each one from a loop running
in a different thread? If there is a need to use textures
I guess I'd better get started on making it then :)
The scenes are rendered to FBOs so they're not tied to any particular
window/context or display method. The scenario is that a user will set one
scene to be rendered and sent to an external display system at 60fps. Once
the first scene is renderin

Using -pedantic is just to get the compiler to help out with spotting
coding errors, in the case
Hi Robert,
is there an equivalent of IncrementalCompileOperation for drawing a scene
graph?
My precise problem is as follows: In my application I have 2 scene graphs to
be drawn concurrently - the primary scene graph must be drawn at a fixed
frame rate of 60fps, the secondary scene graph can take a
Hi Javier,
I just saw this message now (I also posted to maya2osg-users, I thought you
meant this mailing list). I will first try what you suggested.
Thanks again,

Just as a follow up, I'm going to write a simple program that spawns a
thread using OpenThreads and allocates memory to make sure our app isn't
doing something perverse when it comes to memory management. It's possible
that something isn't being cleaned up correctly in the main process when we

We discussed this issue some time ago. You can check the thread

Thank you so much for the response, i will package without it.

Robert,
Thanks for the reply. No, our app does not override new and delete. It's
using the standard operators in C++. I'm not sure on how to answer your last
question. Are you referring to OpenThreads?

HI Shayne,
Doing a new really shouldn't cause any threading problems. Does you
app override new and delete? Is there something else unusual about
our set that might break new and delete's thread safety?

Hi Viji,
I wouldn't recommend jumping through the hoops required to get the
gecko plugin compiling, gecko has turned out to be a real hassle to
work with and really not well suited to the type of embedded use the

After further invesigation on why my thread is hanging, I narrowed it down to
when OSG creates an IntersectorGroup() object via the 'new' operator in the
intersection code.
Just for a sanity check, I did the following in the run() method of my thread:
char *start = (char *)malloc(4)

Hi Wojtek,
I would expect DrawBounds may not work when others do. Thats because
last update of matrices in DrawBounds is actually done in almost hackish
way in the middle of render stage, I would expect that your uniform may
not get updated then. But if you got DrawBounds to work, other should

Hi
Yes, that explains it. And it works, thanks a lot. Just to confirm, since
both MinimalDrawBoundsShadowMap and MinimalCullBoundsShadowMap call
MinimalShadowMap::frameShadowCastingCamera() and don't do anything to the
camera's matrices after that, it should be safe for all variants to update
Thanks for your quick reply.
Some comments:
- I assumed there was support for this since camera paths are supported.
- I am perfectly prepared to extend osgviewer. I appreciate any pointers on how
to best implement this feature.
- maya2osg exports the maya camera as an "osgViewer::Viewer" node

The whole idea of optimal shadow map is implemented in a series of

Hello Manish,
Currently when I'm moving scene using mouse , light also move along the scene.
So how can i fixed light while moving scene ?
When you use the mouse with the default trackball manipulator, you're
not moving the scene, you're moving the camera. In the real world, if

Hi Ares,
There isn't support in osgviewer for what you want.
The OpenSceneGraph is for written for programmers to write their own
applications, applications like osgviewer are very basic in features

How can I write the frames of an animation to disk? The animation consists of a
static model in an .osg file and a camera path in a .path file. (Both were

Hi Sanat,
There are lots of ways to modify terrain, lots of different rendering
techniques that enable this as well. It's rather an open ended topic
and with it kinda difficult to guide to any specific solution,
especially without knowing what type of effect you are looking for.

Hi Matt,
I would not recommend add a Viewer to CompositeViewer, it's
technically possible because Viewer is a View, but having two viewers,
one inside another will just lead to confusion down the line.
CompositeViewer is designed to be a viewer that is composed of a set
of Views. Each View has a
Hi Manish,
I can't work out what you mean here, I'd wonder if others are
similarly confused by what you are after.
The best I can do is suggest looking at the osglight example.
