Good news.
My tnt1 was too poor to support big textures in opengl.
I put radeon 9250 in box and it works OK. Very little cpu usage.
Almost done the code. But I have to put it in 0.6 - I modified 0.4 to opengl.
Tommorow it will be done.

What you think of putting live stream on rotating box?:)
With opengl everything will be possible...

live stream on box, whhat like a texture in directx programming?

lol i wouldnt spend too much on it but i think it would make a cool cycle/sequential switch view but not for serious use. But would definetly look cool!

Glad you have the opengl stuff sorted, i think that 92xx ati would be a min spec anyway.

Yes exactly texture.
Current opengl version I made by putting the texture with live stream on quadrat. There is now much diffrence on putting it on box...

I think so...

Here is the opengl version available for download.

How about for a practical use
When changing from 4 to 9 way split put all images as a texture move viewpoint away from cube, rotate from 4 way view to 9 way view, move viewpoint closer to fill screen again?

I had to rethink one more my opengl code.
Now I'm changing viewport to put another monitor on the screen. The texture is always put on the same object, but the buffers are not cleared so you see previous viewport too.
So what you want it's not so easy to implement.
The textures must be 2^n size. I'm using 1024x1024.
And I'm putting the image only on the part of texture.
I hope you understand.
Take a look at my code. Maybe you'll have some better idea to make it...

Is the opengl version working for you correctly? How about cpu usage?

I had to read the whole programming guide of opengl to know every possibilities...

I doubt it mate i know as much c as i know spanish!
It was just an idea i did a little dirextx programming while bored a few months ago but i suppose it must be similar to opengl, all camera angles and locations.
Im havnt installed your app as yet as im working from home today and the only zm boxes i have access to are in my loft!

I looked at directx for the interpolation etc of the images myself for zm , but as windows has mmx, sse3 etc its not hard to do it on the processor and no hit, as long as you r only doing quick and small interpolations. I tried a 30Megapixel high quality bicubic interpolate with smooth and pixel offset and it took 8 seconds on my fx 53!!!

Cheers Mate

Using new viewer on a 9200 pro 32meg ati card. Using brandnew linux drivers

maciekc · Post by **maciekc** » Thu Jun 01, 2006 10:55 am

Please try to recompile it.

Code: Select all

make clean
make

It looks like a problem with libs or drivers.
Also check fglrxinfo
It should look like that:

Code: Select all

root@debian:~# fglrxinfo 
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9200 Series DDR Generic
OpenGL version string: 1.3.1060 (X4.3.0-8.24.8)

If you don't have there ati vendor it indicates that drivers are badly installed. I had many problems with installing these ati drivers on my box. Maybe you have the same problem.

What distro you are running?
use rpm.pbone.net and look for package containing mysql.h
It is something like that:mysqlclient14-devel
Also check the path in source code in line 57.

Its probably the path as i used the old version (pre opengl) fine. Im not at the machine at the moment i will have a look tomorrow mate

Probably you didn't recompiled the source.
mysql.h was in version starting in 0.2 or 0.3
If you will have problems mail me, and we will surely resolve it together, maybe on skype:)

Just to pick this up,
Try editing your makefile to link in the lib for mysql.
Here is a snip from mine:

Code: Select all

xlib_shm.o: xlib_shm.c
	gcc -c xlib_shm.c -I$(X11PREFIX)/include -I/usr/lib64

xlib_shm: xlib_shm.o
	gcc xlib_shm.o -L$(X11PREFIX)/lib -L/usr/lib64/mysql -lXv -lXext -lX11 -lmysqlclient -Wl,-rpath=$(X11PREFIX)/lib -o xlib_shm

Drop the 64 unless your using a 64 bit proc/os.

Cheers,
Corey

I had xlib_shm running before, but I had to make a new fresh install (Fedora 5) and now I use zm 1.22.3. It gives me the same message:

Code: Select all

/usr/local/src/xlib_shm/xlib_shm -m1

I checked video is 24bpp, running xlib_shm as root, zm running.
Question: is xlib_shm 0.6 compatible with zm 1.22.3 or only with zm 1.22.2?

jameswilson · Post by **jameswilson** » Fri Dec 01, 2006 7:05 pm

there was a dedicated version per version of zm, so i assume this will only work with 1.22.2
