Thanks I'll have a look at osgvertexprogram.
Regards.

Is there an example in OSG that uses IBL?

Hi Alessandro,
For image-based lighting, you can have a look in the Orange Book
(OpenGL Shading Language), chapter 12 (Lighting). There are some
shaders for image-based lighting with a cube map, and you can use them
with a HDR cube map (have a look in the osgvertexprogram for cube map
exa
Hi Alessandro,
when Googling look for Image Based Lighting (IBL) and light probe. IBL is
typically done with a (HDR) cubemap. One for diffuse lighting and one for
specular lighting. When combined with HDR postprocessing effects from the
osgPPU example this can deliver pretty impressive visual r

Hi,
do you already have HDR images? If so, look at the list of plugins, some
of them support >8bit input. If not, you can create HDR textures using
RTT cameras. See e.g. osgprerender.
Do you want to use shaders or fixed pipeline?
osgPPU has an HDR example you can also maybe look at.

I'd like to use HDR images to light my 3D models, how can I achive this with
OSG? Is there an example to start with?
Thanks.
Kind regards.
