Simplifying the trajectory by reducing the planes

Hello all
I have a question with quantity of planes
As I k`now, for create trajectory for robots on KUKA|prc we need create planes at each point trajectory.
But sometimes a lot of points leads to an increase in items for computer processing.
My problem is that I need to create programs with the number of terms up to 200 thousand, but 200 thousand planes is too heavy a volume to calculate the trajectory by a computer.

Maybe someone k`nows how to simplify trajectory…

I think it is possible to create a trajectory whose points are controlled by a set of planes for a certain number of layers.
For example, in the picture, the plane that controls the orientation of the axis at the points located above is indicated by an arrow.
It`s real?)
