Graphics problem

[Andy Chivers]

I am running hpux 11 on a 9000/785/B2000 machine. The graphics devices installed are listed as follows on the delivery sheet:
HP VISUALIZE-FXE color 1280x1024 48 planes
Visualize fx5 graphics

I am running some software called Fluent (CFD s/w). When trying to run up a 3d model I get the following error message:

-----------------------------------------------
Error message from graphics function Show_Device_Info:
The SBX driver needs CMAP_FULL mode to operate.
Use the X11 driver to run HOOPS on this device.
-----------------------------------------------

and the 3D model doesnt appear.

??????Any ideas?????

What's you graphinfo output ? and what visual/colormap are you running X with ?

You can check by looking at /etc/X0screens and/or going into sam->Display->Xserver

Have you tried used pseudo color or tried another mode eg True or Direct with the fx card ? Results ?

How are you patched wrt Xserver and 3d api's etc ....

Have you contacted the vendor ?

Hi,
In my opinion to fully use graphical abilities of your station you have to install:

Graphics and Technical Computing Software (B6268AA).

I've just read that CMAP_FULL for shade mode is not supported on the FXe, FX5, and FX10 whether this is relevant to your problem I'm unsure and probably your vendor can make more use of this info.

The graphics accelerator
does not have the ability to do 332 rendering (which is what you ask for when you specify a PseudoColor Visual and CMAP_FULL).

These graphics cards do not have the hardware needed to support
CMAP_FULL with PseudoColor Visuals. For applications that cannot be changed to
use another visual, setting the environment variable HP_USE_VMX may help. If the above does not help I advise you raise a call with the vendor and to check this out and maybe also log a call with HP too.

Hopefully the vendor will have an opengl version of his s/w which *should* be able to cope a lot better with the newer range graphics cards or be able to confirm if they can get it to work on HP's higher spec cards.

Do you have any other systems where this works ? are they using older graphics cards by any chance ? If yes it adds weight to my suspicion.

All of /etc/X11/X0screen is hashed out (like /etc/default/login) but at the bottom there is a line:

Screen /dev/crt

Hi Andy,

Take a look at the thread below for more info,

Hope this helps.

sounds like you are using the default visual which is pseudo color .... go into sam and try the other options available. If you can answer the rest my questions etc but I suspect I may be close to the truth already :(

[Andy Chivers]

Sanjay, the link is dead, cheers anyway though.

Alex, I've got the vendor looking into it. Will report back here on outcome. Thanks very much for your help.

Alex,

There is onboard graphics (FXe) with the machine aswell this and the FX5 produce the same errors. :o(

You might actually get the HOOPS library to use an OpenGL driver by setting an environment variable-
export HOOPS_PICTURE=opengl/$DISPLAY
That depends on the way the application was linked with HOOPS and the version of HOOPS.
On the other hand, it is very likely that the SBX starbase driver will work if you change the X0screens to read-
Screen /dev/crt
DefaultVisual
Class TrueColor

Setting the default visual to TrueColor may cause trouble for other applications that were not tested with that non-default configuration.

Hi Andy,

Just checked the link i had posted and it is working. In Case you are using the europe support, replace "us-support" with "europe-support" in the link.

Hope this helps.

Sanjay,
got the link going, thanks v much. Installed the Graphics s/w and got the CFD s/w running ok and displayinmg graphics.

Anyone,
I'm being told I'm using a starbase wedriver when i should be using an opengl driver. Any ideas on how to change this?
