More of an openGL question really but I'm having difficulty
understanding the structure produced by the call:
=20
argConvGlpara(patt_trans, gl_para);
=20
If the details in gl_para are in the form of a 4 x 4 matrix then which
values relate to the XYZ translation?
=20
0 4 8 12
1 5 9 13
2 6 10 14
3 7 11 15
=20
I'd expected it to be either (3,7,11) or (12,13,14), but when I output
these values they constantly change, even when the marker is stationary
(except 13).
=20
I'm looking to use the information to calculate distances between
markers. Any suggestions?
=20
Matthew
