I’m trying to have 2 curves:
- 1 for the spline that the camera will follow
- 1 for the speed of the camera
How it currently works:
- At each frame n, I evaluate the 1st curve for n, and the camera’s position is set to (n,f(n)). So currently the velocity is not implemented.
- I have created a python script that creates the spline mesh from the f-curve.
My problem:
- Implementing the velocity curve. I think I need to do some math with the curves but I’m not sure what or how. With default velocity, we set the position to (n,f_1(n)). But with a different velocity, we need to find out what input to give to $f_1$
How I think it could work:
-
The velocity curve has one controlpoint for every controlpoint in the 1st curve.
-
The curve between any two controlpoints n-1 and n, indicates how fast the camera will travel from the first controlpoint to the 2nd one (in the 1st curve, which is the path)
-
For example, at frame 130, we don’t want (130,f_1(130)), but we instead want (130,f_1(160))
