Hi, im using Catmull Rom Splines in my Editor and figure out that when two control points i too near (in a straight line) the spline became a curve. In this case, for example, 100 control points in line doesnt make a straight line, if the points are near. Is it right using Catmull? what kind of splines should i use to camera control? and what the diference between them. (i know that some or smoth and dont pass throught the control points...)

bezier splines are usually smoother than catmull-rom ones, and therefore better for camera movement. however they don''t interpolate through their controll points, like catmull-rom ones do.

if you have points in a line, and you use catmull-rom-interpolation, and get a curve, than a) you are outside of the floating-point precision, or b) your algorithm has faults.
