Software News   Software News : MiniGL 2.1 Beta for Amiga OS 4.x Released
   posted by Hans on 4-Apr-2009 10:58:15 (9420 reads)
I am pleased to announce that MiniGL 2.1 beta has been released. This release includes many bug fixes, including the elusive MiniGL watchdog task crash, which was responsible for random lockups. The release also includes updated developer files for all new features in MiniGL 2.x.

MiniGL is a 3D API which is compatible to OpenGL(tm). It implements a subset of that API and was designed for speed, therefore it directly interfaces with Warp3D. This also means that there is currently no software mode.

The archive is available on os4depot.net's, here: http://os4depot.net/index.php?function=showfile&file=driver/graphics/minigl.lha


Changes in V2.1
---------------
- Fixed the bug in the MiniGL watchdog task. GL screensavers should no longer freeze.
- Fixed a problem that occurred when vertex arrays were included in a display list
- Fixed a bug in rendering huge vertex arrays
- Fixed rendering of line strips and line loops. No more spurious extra lines (e.g. Celestia, GLBoxed blanker and the Dr. Fungi demo)
- Lots of other bug fixes
- Added pop up requesters informing users of problems (e.g., wrong MiniGL.library version)
- Added stack cookies to demos using GLU NURBS functions in order to ensure that they have enough stack
- GLUT now only requests a stencil buffer when applications ask for one
- No longer need -DMINIGL defined when compiling OpenGL apps

Changes in V2.0
---------------
- Added support for evaluators (glMap*, glEvalCoord*, glMapGrid*, glEvalMesh*, glEvalPoint*)
- Added selection support (glListBase(), glNewList(), glInitNames(), glLoadName(), glPushName(), glPopName(), glSelectBuffer(), and glRenderMode())
- Added gluPickMatrix()
- Added gluProject()/gluUnProject()
- Added glGetDoublev()
- Added glIsTexture()
- Added glGetTexEnviv()
- Added glGetLight*() functions
- Added GL_PROXY_TEXTURE support
- Fixed some rendering bugs (e.g., a bug causing incorrect lighting for clipped primitives)
- Added const qualifiers to improve OpenGL compliance
- Mglut.library now has glutKeyboardUpFunc(), glutSpecialUpFunc(), and glutIgnoreKeyRepeat()
- Added text functions to Mglut.library (glutBitmap*(), glutStroke*())
- Added glPushClientAttrib()/glPopClientAttrib()
- Added glDrawPixels()
- Added game mode to mglut.library
- Added glutDeviceGet(), glutLayerGet(), glutGetModifiers(), glutSetOptions() and expanded the number of attributes supported by glutGet()
- Added glut geometry rendering functions including the teapot functions
- Added glut overlay function stubs for completeness (overlay is not actually supported)
- Added glGetMaterial*()
- Added the complete set of glNormal*() functions
- Added glGetTexImage
- Added full set of glPixelStore modes, as well as glPixelTransfer
- Added glutTimerFunc(), glutCloseFunc(), glutWMCloseFunc()
- Added glutWarpPointer()
- Added glutExtensionSupported(), glutIgnoreKeyRepeat(), glutSetKeyRepeat(), glutKeyUp(), glutSpecialUp(), and glutForceJoystickFunc() (note: no joystick support yet)
- Added stubs for glutSetColor(), glutGetColor(), and glutCopyColormap() (note: these functions really don't make sense

@Hans

try with kernel.debug and you will see many things that are not shown with no debug kernel.

From a quick test of WarpView view on my sam440 in hardware mode the colour problem is not fixed by updating the installed libs on my system.

But I don't know if the issue would be fixed with a new build of the application using the newer sdk files in the archive or if we just have to wait on a new hardware driver for OS4.1on the sam440.

It's Warp3D related, so no, the new MiniGL doesn't fix it. I have, however, fixed the problem with Warp3D in the latest beta drivers which will make it into the next update.

(Don't ask for a date; I don't know one)

@Rogue
Get ready for a hoard of people wanting to "beta test" it for you And I'd like to be the first one to do so

Just use the previous version V0.9 beta of WarpView, there the green-bug doesn't appear.

I have a better idea, use the LATEST WarpView, and use DEPTH=16 tooltype to force 16-bit screen depth (which 0.9 used as default).

By the way WarpView doesn't use MiniGL, it uses Warp3D directly, so it has nothing to do with it.

@ Hans

Problem solved, shame on me
the problem was a result of mixed libraries from old and new minigl.

We may take advantage of MiniGL in a future version of Aladdin 4D.
