[MUG] Missing plot graphics
Author: Pete    Posted: 22/09/2000 00:58:58 GDT
>> From: "Pete" I am using Maple 6.01 under Windows 98 Second Edition. Whenever I issue a plot command I get a large white space after the command. If I select in this space I get a border that surrounds what should be the plot. Often times, a second click or right click will cause maple to crash out. The same file will look fine on my computer at work where I am running a trial version of Maple 6. Has anyone else seen this problem? Is there a fix or workaround? Thank you, Peter Laskey

Subject: Missing plot graphics Date: Sat, 23 Sep 2000 08:31:59 +0200 Hi. This annoying problem depends -at least to my experience- on the graphic card which is built into the computer. I encounter the same situation with an ATI card on my desktop PC, while there are no problems on my laptop. Workaround (in my case): reduction of colors to 256.

Do you have it om your computer ? When I shut down the hardware accelleration so that the opengl of the Graphic card is not used any longer, it works on my computer.

>> From: Mike Stecher There is a slightly better resolution of the missing plots than to reduce the number of colors. Try reducing the acceleration level of your video card.

My experience is that it usually occurs with relatively new PCs with certain video cards. There appears to be some conflict with Maple's OpenGL drivers and these video cards. With other video cards, there's no problem! So, is this Maple's problem, or the video card manufacturer's problem? I'm not sure about how you wish to apportion the blame, but here are a number of solutions (for Windows PCs). 1. Moving Maple's OpenGL drivers (recommended) Move or remove the OpenGL drivers provided by Maple, which forces the use of the Windows versions. Maple 6: remove glu32.dll, opengl32.dll, openglnt.dll from the "...\Maple 6\Bin.Wnt" directory Maple 5.1: remove glu32.dll, opengl32.dll from the "...\Maple V Release 5.1\Bin.Wnt" directory Maple 5: remove glu32.dll, opengl32.dll from the "...\Maple V Release 5\Bin.Wnt" directory 2. Reducing the number of colors displayed Change the number of colors used to 256. Click on Start, Settings, Control Panel, Display, Settings, then change to 256 colors. 3. Reducing Hardware Video Acceleration Click on Start, Settings, Control Panel, Display, Settings, Advanced, Performance and set the hardware acceleration to 1/3 or less. Note that you have to reboot the PC for this change to take effect, and that your PC may fail to automatically restart. 4. Using plotsetup() in Maple This doesn't require any changes to your PC. In a Maple worksheet, enter the command plotsetup(gdi): (ignore any warning message you may get). Problems with this: 2D plots may be in black only, and 3D plots can't be rotated in real time (i.e., rotating a 3D plot works as in Maple V Release 4). The command plotsetup(default): restores the original settings. Note that plotsetup(gdi): must be executed (once) in each worksheet which uses plots. Please note that solutions 1 and 4 were provided to me by Maple Technical Support. -- Dr Gord Simons, RMC Math & CS (Girouard 302), Kingston, Ont e-mail: www : www.rmc.ca/academic/math_cs/simons/ intranet.rmc.ca/~simons (RMC only) phone : (613) 541-6000 ext 6096 fax: (613) 541-6584 -=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=- From: "Winfried Auzinger" To: Subject: Comment on missing plot graphics Date: Wed, 11 Oct 2000 09:09:15 +0200 Mike Stecher reported a problem about missing plot graphics. I know that problem. Obviously, plot2d produced void output (also in Maple V Rel.5.1) because of lacking support for certain types of graphic cards (like ATI..). Within Maple this problem can be circumvented by using plotsetup(gdi); before plotting. Winfried Auzinger Vienna University of Technology mailto:
