I am surprised you saw a boost with disable double precision. What specific
element you do you change w.r.t double precision?
I enabled OSG_USE_FLOAT_MATRIX and OSG_USE_FLOAT_PLANE and observed a 10%
framerate improvement.
Might be related to particle systems, which I forgot to mention
Hi Alistair,
thanks for your reply. Your solution seems way easier. Do you have an example
how to do that?

Thank you!

Hello everyone,
I have a question regarding the combination of OSG and Qt 5.4.
I already combined my OSG application with Qt. I used the example which is
shipped with OSG: osgviewerQt.
At the moment my OSG application is quite simple. Its a 3D scene with a
animated 6 axis robot.
I added my

Hi All,
I have just tagged the 3.3.7 developer release:
*O**pen**SceneGraph-3.3.7, **released on 15th April **2015*, key
deliverables in this dev release are:
- Bug and build fixes
- New osg::Camera attachment dirty mechanism to streamline the
adjustment of FBO and Textures sizes

Hi,
I am looking to use OpenSceneGraph to simulate multi-camera images in real
time, but my frame rates are not great with the number of cameras I need. I
currently have 6 cameras rendering to 640x480 images and I see ~8fps max, with
a lot of jitter.
The osg examples have been a great help,
Hi Dave
Yes, I linked to those libraries intentionally, since cmake seemed to detect a
32-bit architecture. Since I have a 64-bit OS, I'd like to figure out how to get
cmake to detect the appropriate architecture. Thats a low priority for me
right now, and I posted the real reason for the
Hi,
I changed my camera.
Now I don't use the method where I create the rtt camera, like shown in first
post.
Now I just created the camera in the method where I setup the scene and it
works...
I really do not get why
Is there a specific order I should follow with the camera calls
Hi,
ok that was a big mistake from my side.
I forgot to set the width and height of the Texture, but I used
getTextureWidth() and getTextureHeight to specify the Viewport.
Well if the Viewport is (0, 0, 0, 0) there will be nothing to see.
But the thing with the orientation I am still trying

Hi Dave,
One of the purpose of the osgRecipes project is to provide all source code
used in the book OpenSceneGraph 3.0 Cookbook, published by Packt Publishing.
And what you found is just corresponding to the second example in Chapter 5.
And it should be a mistake...
Hi,
my bad for not explaining it very well ;)
I want the following:
With the RTT Camera I want to render a specific geometry. The texture I get
from that, will be used in the main scene later.
The RTT Camera must not point in the same direction as the main camera.

you are not showing the part where you use the

Are you setting it up as relative to the main camera?

Hi Matt,
The osgscreencapture example has code use setting up multiple pixel buffer
objects to help improve the speed of reading images. The key is double
buffering the PBO's so you read asynchronously.

You lost me here,
You want a relative RTT camera (pointing to where the main camera
points to) but you set up da absolute camera (having its independent
Viewport, matrix etc.)
You most likely want to have a ABSOLUTE ref frame for screenspace passes
and final output only-
