Please help me sort out the following issues:
Problem area: CAMERA & Helical Bezier Curve.
So far, Iam able to move the camera along a BEZIER Curve [ control points being read from a file ], but I am have problems with a HELICAL Bezier Curve.
The HELIX is along the X-Axis [RHS], going from -x to +x. As the CAMERA moves along the HELIX, all of a sudden, it rolls 180 degrees and this keeps happening at some points along the helix, until we run out of the curve.
Any solution for this [ i.e 180 degree roll of the camera ] ?
The second issue is that the rendering is too slow [ I guess < 1FPS ], when the HELICAL BEZIER path is displayed, but in a normal Bezier Curve [ about 20 control points ], the FPS count is more than 40, when the bezier path is displayed.
