------- Additional comments from [email protected] Tue Jul 21 10:27:04 +0000 2009 ------- AW: Does not happen with lines and line width since with 3D lines with line width the range of the complete 3D scene gest extended, thus the back plane is numerically no longer 'behind' the 3D range. The Z-Buffer uses a discrete integer-based range (in this case 0x0..0xffff), but has no explicit not-used value. Inited with 0 (so that everything in front of will be visualized) it works well, but in the described case the value of 0 is indeed used for the back wall. Since the Z-Buffer already has a 0 there, and 0 !> 0, the pixels are not added. This could be solved by using a special init value to know that the pixel is not yet used. This would not be nice since somehow extra memory would be needed. The other way is to use '0' as the init value and to use only the range 0x0001 .. 0xffff as Z-Buffer values, thus '0' would always be replaced by any pixel (as wanted with unused Z-Buffer entries).
