Re: [gl4java-usergroup] Stencil buffers?

[Sven G. <sgo...@ja...>]

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 !
