Earlier, we discussed how interpolation works and how it's implemented in the FMX framework. As you may have experienced, these topics can be hard to follow without some visual examples (possibly live), but at the same time, a more mathematical approach can be more precise. This section intends to look at both sides of the coin by using images to explain the mathematical concepts behind interpolations.
The following screenshots show the different behaviors of all the interpolation modifier functions. The large red circle is positioned at the final spot, while the smaller red dots are used to represent the trajectory that was followed during the animation.
Please note that the Opacity property of these dots has been set incrementally (reflecting the normalized time) so that you can follow the dynamic while looking at the point's opacity value. For each function, three screenshots have been provided. The left one is for when...
