Hi Robert,
My program was using coin3D for volume rendering before. Now it is
replaced with osg, but I still want the existing machine is able to run osg
version. Last time you mentioned it is possible to implement a crude 3D volume
rendering based on 2D textures. Can you tell me more in details how to do? Do
you mean the current osg doesn't have this feature? Is it required to modify
the source code and recompile again? Thanks.
Regards,
Clement

I'm rather surprised that you'd even attempt volume rendering on such
in capble hardware.
Volume rendering is one of most challenging tasks for any graphics
card to handle, it tougher than *any* game available, it pushes the
memory bandwidth and capacity to the limit, it can brings high end
hardware to it knees. Yet you are trying to get things working on
crappy Intel embedded graphics and virtual machine.
You really need to reset your expectations. Volume rendering requires
decent graphics hardware. Is not the osgVolume doesn't support crappy
graphics, it's that crappy graphics doesn't support volume rendering.
Robert.
