Hi,
I've got a problem with a matrix. I tried to create it out of three
orthogonal vectors (x, y and z) and a point (from). Everything seems to
work, but when I run the program, the last position (avatarmatrix
[3][3]) was always set to "0". "at" and "from" are Pnt3f.
Vec3f z = at - from;
Vec3f x = z.cross(up);
Vec3f y = x.cross(z);
x.normalize();
y.normalize();
z.normalize();
Vec4f v1 = Vec4f(x[0], x[1], x[2], 0.0);
Vec4f v2 = Vec4f(y[0], y[1], y[2], 0.0);
Vec4f v3 = Vec4f(z[0], z[1], z[2], 0.0);
Vec4f v4 = Vec4f(from[0], from[1], from[2], 1.0);
Matrix avatarmatrix;
avatarmatrix.setIdentity();
avatarmatrix = Matrix(v1, v2, v3, v4);
// workaround
avatarmatrix[3][3] = 1.0f;
Does anybody know about this problem ?
Regards,
Sandra
