Module vek::transition

Convenience structures for representing a transition from one value to another.

The Transition struct is useful in animation, especially since it allows you to customize the interpolation function via what's called a "Progress Mapper", i.e an object that also acts as a function which, given a "progress" value, returns the LERP factor to use.

This is especially powerful since it allows for any kind of interpolation curve : exponential, logarithmic, sines, squares... One could even imagine a Progress Mapper based on Bézier curves.

Structs

IdentityProgressMapper	A pass-through functor that returns progress values directly as LERP factors.
ProgressMapperFn	A function pointer container that can map a progress value to a LERP factor.
Transition	A convenience structure for storing a progression from one value to another.

Traits
