Re: Re: [win32] Hugin 2010.1 svn5118 for download

Zoran,

Its a simple

intel C2D (32bit)
1GB Ram
windows XP SP2
Buitin gfx card.

This system is simple no special gfx card etc. All previous builds are working side by side. Your build also works on it. Thats why i like that system :))  If you still need exact processor and motherboard details I will post it on monday. 

I will check latest build again with different enblend version.  


 Thanks.

another enblend build.

I have no other graphics cards ATM to test it but it seems that the
trouble with the preview window is directly connected to it. It seems
it mostly affects old cards, so, maybe upgrade the card?

As to the problems with APSC not detecting CPs properly, bug the dev
team as the default settings are not optimal.

Emad, you said you tested on a few systems but got it working only on
one, could you please post the details of the systems: CPU, GFX,
windows version.

As I previously indicated, maybe not clearly enough, it worked 2 or 3 
times on my PC, but most of the time the fast preview crashed.

So I suspect a memory initialization problem which may disturb the test 
on CPU and/or graphic card capabilities.

My 2 cents.

Re: Re: [win32] Hugin 2010.1 svn5118 for download

Hi windows users,

I'm not on windows but I know there have been issues with OpenGL drivers as such and OpenGL support in graphics drivers on Windows (Can you remember the pvqt/panini posts?).  Some necessary OpenGL settings/functions might not be supported.
Check (1) for an analysis tool. This tool also allows you to tweak some settings as well.

I hope James Legg "listens"  to this thread as he knows a lot about it.

The recent masking feature uses the Multitexture extension, so you need
a system which supports OpenGL 1.3, or the GL_ARB_multitexture
extension. This might not be available on older windows systems, but I
don't know for certain.

I am reading this. I have had a look for OpenGL errors in Hugin. I found
and fixed two, but they could only reproduced when using various fast
preview features, not when first loading it.

OpenGL will sometimes flag erroneous usage, but you have to check for it
manually with glGetError[0]. OpenGL implementations don't have to flag
errors though, there is a lot of undefined behaviour. This could make
something crash on one system and not report an error on another. I
fixed what I could find with it on a Intel 965/Linux system.

It could be a different problem with Hugin, WxGL, or graphics hardware
or drivers.

Re: Re: [win32] Hugin 2010.1 svn5118 for download

I'll add, a few people reported having problem when working in hugin on multiple projects without closing it. I do remember reproducing some problems, and the preview windows was on the list.


So, just in case it helps, do you work on multiple projects in a row, reusing the same running process each time? If you do,  try closing hugin between each project, and starting it over.

If not... then the search must continue.

Re: Re: [win32] Hugin 2010.1 svn5118 for download

Nick I only work on one project at a time. But Fast preview window crashes. 

James legg  is there any OpenGl hack or we have to look for another gfx card. But if this problem persists than hugin usability will be limited. I hope you will find a solution.

The issues are now bombarded as being OpenGL issues. For a complete overview to start troubleshooting the issue(s) I only tried to point the community into that direction as OpenGL driver issues might, I repeat: it might,  be the cause for these issues.

Thanks to Harry link for OpenGL analysis tool, I found that I have
OpenGL 1.1 with some extensions, but GL_ARB_multitexture *not* supported.

*But* when (by chance) I was able to have the fast preview working I was 
able to use masking (the rendering was not Ok, but *no crash*).

Pixel coordinate transformation

Hi, everyone!

I have a question about hugin. I wonder what geometric transformation
the cylindrical projection used?

That is to say, I have generated a 360 degree panoramic Image from 6
images using cylinderical projection, and there is a point A(x,y)(x,y
are pixel coordinates) on the fifth image, how can I calculate its
coordinates A'(x',y') on the panoramic image?

Which part of the sourcecode realize such function?

Look forward to your reply, thanks!
