Hi Dan,
Are you running the viewer multi-threaded? By default the OSG will
check your available CPU cores and enable multi-threading if you have
2 more more cores so it may well be multi-threaded.
When the viewer is running the draw thread in a separate graphics
thread the previous frame
Hi
I've recently been testing out the new VDSM shadow implementation in trunk,
it's looking really nice.
I have a problem with the default fragment shader - it stops working as
soon as I attach a vertex shader, even a quite innocuous one like this:
void main(void) {
gl_Position =
Hi Mike,
You can't just throw in a very simple vertex shader to replace the
built in vertex shader and expect it to work. The vertex shader has
to use texgen to create the texture coordinates for the shadow map.

Thanks Robert, I had a niggling feeling it was something terribly
obvious...For the benefit of anyone following in my footsteps, you might
want to start off with a vertex shader looking more like this:
uniform sampler2D baseTexture;
uniform int baseTextureUnit;
uniform sampler2DShadow
1) Is the CAVElib creating multiple graphics contexts? If so there you'll
need a GraphicsWindow on the OSG per context you can't reuse the
same window per context.
Sorry, forgot to describe CAVElib's behavior there. CAVElib will create a
thread for each wall of the cave and thus a new

I'm been having the same problem today and all weekend, connecting to

Can somebody do a test for me? I'm using OSG 3.0.0 and this works with NVIDIA
Driver (Linux) 260.19.21 but doesn't seem to work with newer versions of the
driver (e.g. 275.31 beta) with no other changes being made. I've been in
contact with NVIDIA with this problem and they seem to think that
Robert,
Thanks for the replies.
Anyhow, the reasoning has to do with risk and periferal support; head tracker,
a wand, and other assorted goodies CAVElib already deals with. I probably
could write something that did the same but would have a heck of a time
convincing them it would be the best
Hello,
Hoping for a bit of help.
What I've been doing:
I have been using osgdem to merge a dted data geotiff with a geotiff with rgb
color values into an ive terrain complex. I am using the -t flag to tell
osgdem that my geotiff should be treated as a texture file. However, the rgb

Hi Joshua,
See if you can use the peripheral support from CAVElib and just plugin
in the camera view and projection matrix settings into the osgViewer's
Camera's and let the OSG do the threading and rendering.

Due to previous discussions on the topic, I have been careful to generally

Hi Ethan,
the triangle mesh of the terrain will represent the resolution of the DEM, not
of the texture. Usualy texture resolution is higher than the DEM ones,
therefore you would reduce your image resolution if you don't use textures but
try to assign each vertex a color.
But nevertheless
