Hello, glGetIntegerv(GL_STENCIL_BITS,...) in GL4Java indicates that there are 0 bits in the stencil buffer, but when I run the test in a C application using Mesa, it says the stencil buffer is 8 bits. Did I forget to initialize something, or doesn't GL4Java support stencil buffers?

Thank you for finding a bug ! I will have time this weekend to check this one. Of course, GL4Java should support glGetIntegerv(GL_STENCIL_BITS,...) ! Please add information about GL4Java version number, OS (version), OpenGL version - ALWAYS ! Please send a little code snip to investigate (about 100 lines or so) also ! Thanxs.

I didn't realize it was a bug, so I forgot some traditional bug-report information. I have attached a java file showing the problem (0 bits in stencil buffer). I use gl4java 2.1.3.0 on Linux 2.2.13 with JDK 1.2.2, glibc 2.1.2 and Mesa 3.0.

I have testet gltest with:
WinNT 4.0
Jdk 1.2.2 & native threads & symantec jit
GL4Java 2.1.2.2 (current windows version)
Output:
Stencil bits are 8
Color bits are 5
So it must be a GL4Java 2.1.3.0 on Unix with Mesa 3.0 bug !
{ Mesa 3.0 Software renderer ???)
I will check this for unix & mesa 3.1 this weekend !
Then I will put the new version for Mesa 3.1 online !
Yours, Sven

Dear GL4Java Users, the new version is pending :-( I am sorry, but I do not have had enough time this last weekend. I hope I can put it online at 23th January 2000. Thanxs, Sven -- mailto:sgo...@ja... www : http://www.jausoft.com voice : +49-521-2399440, +49-170-2115963; fax: +49-521-2399442 |

Now I have tested the Method glGetIntegerv(GL_STENCIL_BITS,...)
with GL4Java Version 2.1.3.2 and:
- WinNT 4.0 + Matrox G200 OpenGL
Stencil bits are 8
Color bits are 5
- WinNT 4.0 + NVidia GeForce256 + Elsa X2 OpenGL Driver
Stencil bits are 0
Color bits are 5
- Linux + NVidia GeForce256 + NVidia GLX 1.2 Mesa 3.0 OpenGL Driver
Stencil bits are 0
Color bits are 5
- Linux + Mesa 3.1 Soft OpenGL Driver
Stencil bits are 0
Color bits are 5
So I guess it is about the Stencil capabilities of the gfx-card and the
driver.
I guess the Method glGetIntegerv(GL_STENCIL_BITS,...) is OpenGL1.2 only
- right ?
Or should we enable Stencil with glEnable(GL_STENCIL...) ?
But it is not a bug in GL4Java !
Yours, Sven

In the example stencil.c that comes with the Mesa distribution, there is an example of having an 8 bit stencil buffer. However, the example calls glutInitDisplay(GLUT_RGB|GLUT_SINGLE|GLUT_STENCIL), so I guess one must do some initialization, as you say with glEnable(GL_STENCIL). You could implement it the same way as the current "doubleBuffer=true", i.e., "stencilBuffer=true" in the users' preInit() method.

This kind of initialisation is if course different to glEnable(GL_STENCIL). Well I will check this out next 28/29 Jan 2000 or 4/5 Feb 2000 ! Others are welcome to implement this piece of code.

I'm using GL4Java 2.1.0 with Mesa 3.0-4 and with JDK 1.1.6. And - Sven, when will be available GL4J using Mesa 3.1 (and GLU 1.2). Nothing to hurry up too much, just asking. Bye, Max |
