I have a program that displays a terrain from a heightmap and some objects from OBJ files on that terrain; I have also written routines to move the camera on all axes as well as a mouse “freelook” function for the camera.
I’d like to move the camera on a smooth, curved path like a Bézier curve; I was wondering if someone could point me to a tutorial with a code example for moving the camera in that way.
I did find and try out something using glMap1f() and then using the evaluator glEvalCoord1f() on that – which can indeed be used to draw a nice curve with GL_LINE_STRIP.
However, I don’t want to actually draw the curve on the screen; I want to have a function which can give me the x, y and z coordinates for the camera as a function of time (or something else) which I can use to move the camera along.
Thanks in advance!
