Hello as a new subscriber. I have a problem with widgets-sgi in Mesa version 3.1. I am using Motif Swim 2.0 commercial libraries and Mandrake Linux 6.1 with ATI 128 = Xpert. Get following errors on linking: boilerplate.o: In function `main': boilerplate.o(.text+0x9fd): undefined reference to = `GLwCreateMDrawingArea' /usr/X11R6/lib/libXm.so: undefined reference to `_xstat' collect2: ld returned 1 exit status mesa-widgets compiles OK and demos work fine but GLwCreateMDrawingArea does'nt get compiled - even with ./configure __with-motif. I notice that GLwCreateMDrawingArea is declared as an external in code. Where is this referenced to? This all worked in Mesa-2.5 with Red Hat 3.1(I think) Can anyone help? Regards Gerry Cook |

It had to die sooner or later because it doesn't suit hardware T&L - and *eventually* 3Dfx will wake up to the realisation that if they don't get their act together and produce a machine that can do 20M triangles a second in hardware, they are out of the business. 2) If you write in GLIDE, your program will only be able to run on 3Dfx hardware. OpenGL is portable and will work on lots of different hardware and under lots of operating systems. 3) If you think you can write the higher level transform/clip/lighting code better than the guru's who wrote and optimised Mesa - then GLIDE will certainly be faster than OpenGL/Mesa because (on 3Dfx machines) Mesa runs on top of GLIDE. However, if you are not a truly great optimisation nut with *WAY* too much time on his hands - you are probably better off using OpenGL/Mesa. Conclusion: Don't use GLIDE.

Depends on which 3Dfx card you have - but I'm guessing from the
question that you have either Voodoo-1 or Voodoo-2.
If that's the case then you need to set the shell variable 'MESA_GLX_FX'
to 'windowed' as in:
BASH:
export MESA_GLX_FX=windowed
tcsh:
setenv MESA_GLX_FX windowed
This is nowhere near as fast as full-screen mode - but a lot faster
than software rendering. If you have a Voodoo-1/2 card then that's
as good as it gets because the hardware is physically incapable of
rendering into a window and Mesa has to copy the image out of
the 3Dfx card's frame buffer and into the 2D graphics card...which
takes something like a tenth of a second for most "reasonable"
hardware setups.
If you have a Banshee or a Voodoo-3 then rendering into a window
should be fast.

Mesa (and OpenGL) have no special functions for loading images, you have to do that yourself - or find a support library to do it for you. Hence, there is no special image format for OpenGL programs. Dunno about BMP - but for JPEG, you need to use libjpeg to pull the image into memory and then add jour own code to stuff it into texture memory. Personally, I try to avoid JPEG (because it *sucks*) and BMP (because it's Microsoft *and* it sucks) and instead I support PNG (because it's *wonderful*) and SGI's RGB format (because it's *simple*). For PNG images, check out 'glpng' (just do a Google search and you'll find it) - for RGB images, you can write your own loader in about 10 minutes from the spec: ftp://sgi.com/graphics/SGIIMAGESPEC ...or steal one from one of the Mesa sample programs.

Hey everyone I have been trying to figure out how to get Mesa to compile = under Win98, but have not been able to. Eero Pajarre has been trying to = help me, but things are still not working. I am using ver. 3.2.1, have = the 2.4 version of the Glide SDK for my VoodooII card, and am trying to = compile it with Visual Studio 5 sp3. I also have the DirectX SDK ver = 6.1 installed if I must use that. I would prefer to use glide because = it seems to be faster and would allow me to upgrade DirectX back to 7.0. = I am running this all on a K6-2 3dnow processor, running at 366mhz with = 64megs of ram to work with. Has anyone successfully done this and would = be willing to send me a detailed walk through? If necessary it would ne = be a problem for me to edit the code by hand if some gave me detailed = enough instructions. Thank you in advance crazy_j_c |

On Voodoo-1, -2 and -3, the limit is actually 256x256 - and that's a hard limit for those cards - most other cards have much larger limits but those Voodoo's are beginning to show their age. There is also a restriction that the aspect ratio of a map may be no more than 8:1 - so you can't have (for example) an 8x128 map.

Recently I have tried to compile the MESA 3.3 libraries on a copy of Slackware Linux 3.5. I am constantly receiving an invalid option error with the compiler flag -fstrict-aliasing. So, in an attempt to get the thing to compile, I removed this flag and everything compiled fine. However, then when the it all went to link for the samples/demos, it complained about some missing symbols. I have a feeling that this could just be my version of gcc which might be out of date so I was wondering if there was a minimum version of gcc that could be used to compile these libraries and if so,does anybody know what it is? __________________________________________________ Do You Yahoo!?

You are also STRONGLY advised to use something like glutWarpPointer to ensure that the mouse can never leave the underlying window because as far as X is concerned, the program is still running in a window - and if the mouse leaves that window, you could lose keyboard focus and also make it very hard for the poor user to get the cursor back onto the screen. > if I use display list for my program when in my program the are repettion of > opengl code . > the program will be more faster ?? That depends on the platform you are running on. Some OpenGL implementations go quite a bit faster - but there have also been some implementations that went a tiny bit slower in display list modes!

There should be no compile-time differences between Mesa and OpenGL. #ifdef's for extension testing is reasonable though. At compile time, you can check glGetString(GL_RENDERER) to learn if you're using Mesa. But even that shouldn't normally be needed. What problem are you trying to deal with here? -Brian |
