Hi,
I have trouble to compile nvtt 2.0.8.1 from the code.google.com webpage with
cuda support.
My system is: Kubuntu 10.04 64 bit
I have installed the 280 driver from the NVIDIA homepage. as well as the CUDA
4.0 SDK, the CUDA Tools and the Sample programs.
I use GCC 4.4.3
The sample programs c

Hi everyone,
osgconv seems to be (almost) the holy grail I was looking for: It can
simplify models and apply compression to textures. But it does not
appear to accept a maximum texture size. On Windows, I am trying the
following (where I use a building model made in Google Sketchup)

Problem solved! I had buried the reference to my scene class in my console
class (which acts as a callback for a node I was destroying)...
Long way of saying "whoops", I guess.
Anyway, thanks for the help - I certainly learned a good bit nonetheless.

AT LAST!!! :-)
I managed to solve my problem. Now I have a beautiful textured Earth!
I had to:
*compile OSG with imageio instead of Quicktime
*compile OSG with Cocoa as a windowing system
How happy!

Hello folks,
the main intention is to use an off screen RTT scene setting to generate
textures for the main scene asynchronously. The RTT base seems to work, but
rebinding the color_buffer at each frame to a new target (image or texture)
does not work. (During the development osg::Image instan

Hi Alberto,
thanks for your answer, but there is a Problem with blender.
When I want to add the osgExport file ("Install Add-On"), there happens
nothing.
What I have done

2.) the osgExport.py in blender-2.59

Hi, Manu Cant comment on performance gain with pure gl, but you can write small test to see possible gain. Osg dont share fbos with cameras and dont keep track of vbo's binded so most of gain would be from reducing number of glBindFramebuffer...(..) calls and geometry setup (vertex\index\texcoord a

The code that you suggest is erroneous looks fine, while your code

reference count without deleting the object, it's a special case that

Thank you for answers. I supplied a short example program as you requested. The

positions with a positive value, so it's moving to the top-right. Secondly,

inside the shader.

This turns out to be more complicated than I anticipated. You were right - at
least partly.. I think. I did some research on ref_ptr's (consulted OSG 3.0

To be more specific, when my dragger is hidden by another geometry, the camera

Any idea about this ?

Thanks for the speedy reply Sebastian,
I mainly needed to know whether I was missing something simple or not as i
don't really have time to learn enough to get stuck in to writing shaders.
Hopefully I can return to the problem at some point

Hi, James
You can write shader which will use texture depending on triangle facing, there
are bool gl_FrontFacing variable accessible in fragment shader (or you can
check viewspace normal z sign).

After looking at sources, it looks like only possible cause of malfunction -

Hi,
You can use node masks so intersector visitor would check intersection only on
nodes you want, or keep separate graph for intersections search

Hello Alastair,
If you parse the forum/mailing list for shadow and multitexturing or
other terms you will find a heap of information about this.
In general you'll have to write your own custum shader in order to use
shadow with more than one texture /3d-texture and so on.
