Hi,
According to the 3.0 release notes, OSG introduces support for OpenGL ES 1.1,
OpenGL ES 2.0.
I'm using OSG 3.1.1, and I have built an application which works fine when I
compile OSG to use OpenGL. It's a pretty simple app that reads in a textured
3DS model and displays it.
However, when
OSG core works from the box what doesn't work from the box is osgText and
other things that require the user to include his own shader to make work
things. I have code that replaces the estandard stats handler with one 100%
compatible with GLES 2.0 BUT it's not something that we can include in OSG
Hi Jorge,
first off, thanks for the quick reply!
My model is being read in correctly. In fact, I can display it using the
shaders I've attached above. What I'm concerned about are two things:
1/ Why all the warnings appear that I posted above? I attached the shader
program to the root node,
Hi,
It is fixed in the OSG-.3.1.3 but I get rid of ffmpeg plugin and modified a
CMakeList ...
Thank you!

Hi,
after removing everything from my SG except the node with the 3DS model, I now
see only a few warnings in the logfile. After the shaders are compiled and
textures loaded, I get
Code:

Hello all,
I have an osg project that uses shaders to write float32 values representing
temperatures to my framebuffer texture. I would like insert a CUDA or OpenCL
kernel to take those temperature values in the framebuffer and reinterpret them
as colors based on various sensor effects.
My
Robert et al.,
The topic of culling vis-a-vis shaders has come up a few times recently.
The issue is: if you transform or emit vertices in a vertex, geometry, or
tessellation shader, the new position information is not available to OSG's
culling mechanism. This may result in visible geometry
osg Text is really easy to make it work with ogl, you have to use a shaders
that is inherited by the osgText node that can read from texture and that's
pretty much all. The other errors... well openGL extension is not supported
will be probably because it needs some qualifier that it's not
To follow up on Jorge's reply:
Here's an example of how you can use shaders for osgText:

If you're still having issues, increase the OSG debugging output:
(osg::setDebugNotify(...)) and

Hi Stefan,
thank you for the update, I look forward to trying the avfoundation plugin...
but can you provide some help to let me configure CMake in order to generate a
target for that plugin? So far it is missing in the project I get from CMake.
Thank you.

Hi
there are great courses, but dont overestimate your time and capability, some
courses are quite time consuming... last time i simultaneously started two
courses with four weeks delay, and it was hard to catch up between work and
stuff.

Hi Mohamed,
check the OSG_WINDOWING_SYSTEM-var in cmake. It should be Cocoa.

Do I need to install a specific WindowSystemInterface ?
Hi Alessandro,
You'll need IOS 6.0 for the avfoundation-plugin. Check the
IPHONE_SDKVER-var in cmake, it should be 6.0

Jeremy,
On the 2nd you mentioned some Coursera courses about to start. I looked
on the site and didn't see them. Have they already started?
