I spotted a possible Problem in matrix4.h

Line 00189
should be

Code: Select all

00189 newMatrix[11] = m1[3]*m2[8] + m1[7]*m2[9] + m1[11]*m2[10] + m1[15]*m2[11];

Line 00224
should be

Code: Select all

00224 m3[11] = m1[3]*m2[8] + m1[7]*m2[9] + m1[11]*m2[10] + m1[15]*m2[11];

sorry for the "up" but I think it's important.

Niko we definitively need your point of view .

That's interesting, now I'm quite confused. In one of the newer versions 0.6 (I think, or was it 0.7?) I had these two lines changed, because of another bug report. I didn't think a lot about it, because it looked simply right for me.. Now I'm confused. I'll do some investigations.
