Hi Steven,
thanks for reply.
I tryed to add shadows on my scene copying the osgShadow demo example. When I
cleanbuild the project, the make returns an error... I don't understand why.
Can you help me?
Here is the code I added to my project:
Code:

Hello,
I would like use render to texture in every render step. My texture resolution
is 2048 x 2048 and it is very slow. There are tipps and tricks to speed up the
render to texture?
With 2048 x 2048 I get around 15 FPS and with 1024 x 1024 I get 45 FPS.
Thanks
Martin

For the small scene like yours simplest ShadowMap technique should be
sufficient. I am recomending it because, extending this technique to support
multiple lights will be easiest

We're using the OSG Jasper based plugin 2.8.3. The program dies in the

Hello Mukund,
There are two factors here: your setting the frustum, and OSG's compute
near-far mode.
First, since you are calling setProjectionMatrixAsFrustum yourself, you
are resetting the coordinate system to be Y-up, with the Z axis going
out of the screen. So when you make a line that
