Hi.
I do not know if any of you experienced anything like this with any
other 3D CAD programs, but...
I use Realsfot's R3D, and I experience a strange behavior. R3D should
use OpenGL, but here is what I see happening:
First, I feel rather stupid: I discovered that I have had hardware
acceleration OFF ever since I started using R3D. No wonder I could never
use GL shading and I always had to resort to wireframe... I thought R3D
was very slow.
Anyway, I have discovered it when, today, I have bought a GeForce 4400
and while installing it I realized I had previously hardware 3D accel.
turned OFF..
Anyway, after installation glxgears jumped from 20 to 580 FPS :-) (full
screen, 1280*1024, 16bit)
So, I instantly started up R3D in order to FINALLY see my models in
glorious OpenGL rendering. Oh, bother: speed is absolutely the same as
before, equivalent to when I had no hardware 3D acceleration on my
machine. All the openGL stuff is there, I have MESA,
(mesaglu-4.0.1-74
mesaglut-4.0.1-74
gle-3.0.6-98
gtkglarea-1.2.2-301
mesaglut-devel-4.0.1-74
NVIDIA_GLX-1.0-2960
), the gl test suite runs fine, and I attach the output of the 'glxinfo'
command to this mail should anyone want to take a look...
VariCAD takes advantage of this and I have now a large improvement in
speed, so the OpenGL setup is correct.
I am puzzled - what am I doing wrong? Looks like R3D is not using
OpenGL, but this should not be the case.
Thank you
Maurizio
