Problem with running samples

Installation
1

Hello,
I’ve installed the newest panda binary, but I have some problems running the samples.
Python simply crash with this message:

:display(error): Window wouldn’t open, abandoning window.
d
:display:wgldisplay(error): Could not share texture content between wglGraphicsStateGuardian

I’m on a AA1 with a Intel GM945 integrated card, so I knew I was going to have some problems, but the last panda3d version I used (1.5.x) ran the shadow example (one of the crashing samples). With many artifacts (I love violet shadows :laughing: ) but yet working.
Thanks in advance!

Did you install the latest drivers?

Otherwise try DirectX mode (not as well supported as OpenGL though), try editing this in C:\Panda3D-1.6.2\etc\Config.prc:

load-display pandagl

replace “pandagl” with “pandadx9” or “pandadx8”.
You can also use software rendering using “tinydisplay”.

3

@pro-soft: May I ask why you suggest switching to DirectX? While it may be a good idea for developers, it is not so nice for end-users IMO (not because of DirectX, because of manually switching).

The short answer is that graphics drivers suck.

Some graphics drivers work in OpenGL mode but not in DirectX mode; otherwise work well in DirectX but not in OpenGL. Some work in either, some work in neither.

Unfortunately, there’s not any real good solution to this problem other than to provide a mechanism for your end-user to select which graphics API to use. This is why so many commercial games offer this option to the user.

(If the graphics driver is so broken as to be unable to open a window in a certain API, then Panda can automatically fail over to the first API that successfully does open a window. But often the graphics driver is only partially broken, so that it does successfully open a window, but that other features like offscreen rendering don’t work properly. Panda can’t really auto-detect this situation.)

Related to the other post: At least Panda3D < 1.6.0 was able to render all examples and Panda3D 1.6.0+ is somewhat picky. No driver changed, nothing changed at all. I’m a bit puzzled why everything was running fine some time ago.

Are you sure that many commercial games offer this options? AFAIK most Windows games use only DirectX with the exception of all ID products. At least all games that I own (aren’t that many, so it’s a rather limited view) don’t offer an option to change the rendering API.

My personal preference is OpenGL as well, and with your addition of the callback mechanims, I was happy. Now this nicenesses are vanishing.

6

It’s true that if samples that used to work in previous version no longer work in 1.6.x on the same driver, then we must have introduced something recently that freaks out the driver in question. It’s important to me to track this down, but it can be really hard to do so, particularly if I don’t have the hardware and driver in question on my desk.

One of the things that can help is to isolate the problem. Changing the API is an important data point. For instance, did it stop working in OpenGL only, and does it still work in DirectX?

I assumed that I have the same problem like in discourse.panda3d.org/viewtopic.php?t=6088 and therefore it has only to do with 1.6.x.

See next post for results:

Also try running with “notify-level-display debug” and post the output in both versions.

With color-bits set to 0, simple samples are running with OpenGL (the shadow
example has no lighting and shadows, but besides this, it is running and the
geometry is visible). But here are the details:

Ah, I think I have a theory.
There could be a bug in the code that chooses advanced pixel formats, or a bug in pixel format #57. I think the code that determines the best quality FramebufferProperties changed in 1.6.0 right? That could explain why it worked before, it simply chose a different pixel format then.

Can you try putting something like this in Config.prc?

gl-force-pixfmt 5

That will force it to use pixel format #5 - which looks good enough. Also change the Config.prc settings back, then try running. (with pandagl).

You could also carefully try other, advanced configs (if they provide enough bits to satisfy the needs set in Config.prc), maybe try <56, 58 or so.)

Config.prc default, only with the line “gl-force-pixfmt 5” seems to work. Simple examples, up to the normal mapping sample works. The shadow sample has no shadows, but besides that, everything is fine.

Tried from 39 up to 55, and none of this works.

Interesting. So pro-rsoft’s guess appears to be correct: your driver, for some reason, offers this set of advanced framebuffer formats, none of which actually work. When we added code to Panda to look through the list of advanced framebuffer formats in addition to the first-tier ones, it stopped working for your driver.

I guess the right workaround will be to automatically fall back to the “preliminary” framebuffer format, if the advanced one doesn’t work. I’ll see about putting that code in.
