Hello! I’m new to Panda3D; I’ve just started messing with the tutorials.
I’m getting some strange graphical corruption when I try to run the second tutorial program.
It’s like the screen isn’t getting redrawn properly; it smears as it rotates. Here is an example:
The more it rotates, the longer that smear gets.
I’m running Ubuntu 9.04. I’m using an Intel integrated X3100 graphics card. Any idea how to resolve this?
Sorry to hear about the problems- but with an integrated video card 3d performance will be spotty at best- especially under Ubuntu.
Mind you that Intel has made leaps and bounds with their graphics cards but they are not meant for gaming or 3d usage over all. The reason why is power, video, and processing:
developer.nvidia.com/object/cg_t … _home.html this link is to a free book on cg programming by nvidia and it explains the how and why video cards do what they do.
Anyway
For under fifty bucks you can buy a nvidia card that can handle the engine properly. But if you are using a laptop or cant afford the video card two other things that will help:
one: google running 3d games like Jade Empire, WOW, or Warhammer etc on Ubuntu using Intel integrated graphics. They have a lot of tricks on getting your video card to perform better. But turning off Compiz and desk efffects in Ubuntu will be the minimum. Also there are some accelerated graphics drivers for Intel that promise better performance- but results are not consistent.
two: Increase your system memory- On my hybrid that has intel video I tripled my video performance by increasing my system memory, becuase many intel cards integrated into the motherboard can use physical system memory for additional resources. I can program on Panda but I canot do much texture swapping, chrome rendering etc it just tears and smears like your screen shows becuase the card just cannot handle it. But I can do the panda scenes fine but I have four gb memory too and 2.5ghz processor.

Ok, unhelpful.
I know Intel graphics cards don’t get great performance, but I can run Guild Wars, Unreal Tournament 2004, Knights of the Old Republic, and Prince of Persia: Sands of Time (the latter with graphical detail on high) with acceptable performance in Windows. I’m not planning on doing anything graphically intense with Panda, and Intel cards aren’t that bad.
Thanks for the link to the book, but I’m using Panda because I don’t want to get down with the nitty-gritty of graphics cards. I’m a n00b at 3D graphics, I don’t have a ton of free time to learn this right now, and I like abstraction.
This is a laptop. I can’t upgrade the hardware, and getting an Nvidia card in this model would have cut the battery life to like a third of what I currently get.
Yeah, I’m not using Compiz, though I eagerly await DRI2, which will supposedly make all those issues a thing of the past.
All Linux Intel drivers have 3D acceleration. You’ll have to be more specific. 
I’ve got two gigs of ram and a dual core processor. Like I said, I can handle stuff loads more complex (heck, even HDR. It’s slow, but I don’t get corruption) when I’m running Windows.
Performance is a lot worse under Linux, but Panda3D is the first engine I’ve encountered that’s actually had graphical corruption. Are you saying this is a driver issue?
Edit: Ok, yeah. It is a driver bug. Sorry.
For me it was driver issue- Panda ran fairly well under Windows Vista on Intel Integrated but not Ubuntu.
I had to track down a specialized Intel driver for Ubuntu to get any performance at all. Im sorry but I dont use that computer anymore and I do not remember the driver name.
I am a noob at Panda and Python- but I think this is a Ubuntu / Intel driver issue rather than a Panda one since I had the same video and overcame it with no adjustments to Panda3d. Yes I could play Guildwars- but not Dawn of War, Spore, or Jade Empire with any performance on Ubuntu and Intel.
Intel Integrated Video are not bad cards, but they are not designed to be gaming cards- they are low level / low load graphics cards.
Sorry I couldn’t help you.

Interesting. Digging through the aranaxis source reveals they disable the GL_EXT_texture_compression_s3tc, GL_ARB_multitexture and GL_ARB_vertex_buffer_object extensions when safe mode is enabled.
Can you try running pview, moving the camera around, and see if that gives any issues? Can you try the same for an entirely untextured model?
Also, please give me the full output of running pview (if it also gives the problem) or the sample with this added to /etc/Config.prc:
notify-level-display debugI exported the default cube in blender to an x file, then used x2egg to convert it, and loaded it into the scene rotation demo, and that is also leaving a smear.
I get the same issue with pview. It leaves a trail of textured blue triangles. Using the untextured cube in pview has the same issue.

61.1529 fps average (16.3525ms)In Blender, the top and bottom areas of the display view are showing this same corruption, (but not the menu, the control panel at the bottom, or the center where they cube is). Definitely wasn’t like that before I upgraded to Ubuntu 9.04.
Wait, it says it’s using Mesa? So you’re not using true 3d acceleration?
What does glxinfo say?
I was under the impression that the Intel drivers were supposed to be using Mesa. Is this not the case?
glxinfo says I’m using direct rendering. That generally implies 3D acceleration, doesn’t it? WarSow runs at acceptable framerate on medium settings, and I can use shiny desktop effects in KDE4, so there’s some sort of acceleration going on.

0x8a 0 dc 0 32 0 r y . 8 8 8 8 0 24 8 16 16 16 16 0 0 SlowI was going to guess that the blurring issue is linked to GL_EXT_texture_compression_s3tc. S3TC didn’t used to be supported by the Intel drivers because it was patented. Before I upgraded Ubuntu, UT2004 would spit out errors about it and degrade to a different texture compression method, but I just ran it and didn’t get any errors. It seems to be running several FPS faster than it used to, also. There is a little bit of smearing with messages that appear on the screen, but they get wiped away fairly fast.
…but that untextured cube was also smearing, so that can’t be it. 
For the record, many Linux drivers use Mesa as the OpenGL front-end, but they are still hardware accelerated. “Mesa DRI” is the key phrase there that indicates hardware acceleration, and that’s what you’re showing. On the other hand, “direct rendering” is an old, outdated X11 concept, and has nothing whatsoever to do with hardware acceleration.
The bug in question certainly appears to be a driver bug. Something’s going wrong with the clear operation, somehow. I doubt it’s related to texture compression, but it might be a problem with the stencil buffer or some of the more exotic framebuffer bits. Try putting:
framebuffer-stencil 0
framebuffer-multisample 0
framebuffer-alpha 0
in your Config.prc file.
If upgrading your driver is an option, I’d recommend it.
David
Direct rendering isn’t about 3D acceleration? It’s always corresponded to it for me in the past (with ATi, Nvidia, and Intel cards), and the Gentoo docs still used it as of last September. Meh, whatever.
Yeah, the framebuffer options didn’t make a difference. I shall look into getting an updated driver.
Thanks for your help! 
Well, there’s a confusion of terms. “DRI” stands for “Direct Rendering Infrastructure”, and it is indeed about hardware acceleration. But “direct rendering” as reported by glxinfo is talking about something totally different; it basically means that the X11 context is local, as opposed to on a remote machine. Software renderers can still report “direct rendering” to glxinfo.
David
Upgrade to Ubuntu 9.04… The Intel drivers are much improved… I have a VAIO with the same chipset and it works with OpenGL apps much better than before…
Cheers.
There are known performance regressions with Intel cards in Ubuntu 9.04. Some stuff runs better, most stuff runs a lot worse.
Which isn’t really a big deal for simplistic 3D games like what I was trying to make. The graphical corruption is sort of a showstopper, though. It looks like I’m stuck until they get these driver-level graphical corruption issues sorted out.
how about using tinygl for now. and switch back to opengl once the drivers are usable again?
How would that work with Panda3D? TinyGL looks like you list it in the includes and then make OpenGL calls directly.
Panda has TinyGL support built-in, beginning with 1.6.x. Just change your config.prc line from:
load-display pandaglto:
load-display tinydisplayIt is not, strictly speaking, TinyGL any more. It is a software renderer that was originally TinyGL, then heavily modified to integrate it efficiently with Panda’s rendering engine, and also to add useful features like blending and multitexturing.
David
It spits out errors now. Apparently something to do with libtinydisplay.so and XAllocSizeHints.

Your Config.prc file must name at least one valid panda display
library via load-display or aux-display.Hmm. Some version dependency issue on your X11 libraries, maybe? It sounds like your X11 libraries are not the same version that libtinydisplay was built against.
Maybe if you downloaded Panda from source and built it yourself?
David
Did anyone ever find a solution to this problem? I am having the same issue. I suppose if worst comes about, I can wait 5 days and see if Karmic fixes the problem.
