Has anyone actually got the quaternion routines working using them ?
Using the below code when I hold the up key down then It "bouncing"
up and down on a very small angle ...
I am using the cvs version here ... using the 1.1.11 rotation round
y worked but round x and z caused the whole model to become really
warped as I rotated round ... but at least it worked better than I
get now ..
void Camera::Rotate(float x, float y, float z)
{
sgNormalizeQuat (rotation) ;
sgRotQuat(rotation, -x, 1.0f, 0.0f, 0.0f);
sgRotQuat(rotation, -y, 0.0f, 1.0f, 0.0f);
sgRotQuat(rotation, -z, 0.0f, 0.0f, 1.0f);
}
for dislplaying a cube...
glLoadIdentity();
sgMakeRotMat4(rotationmat, rotation);
glLoadMatrixf((float*)rotationmat);
glTranslatef(position[0], position[1], position[2])
show cube etc...
thanks,
