Restores the step size scaling in ray direction #136

Closed FelixTUD closed 3 years ago

FelixTUD commented 3 years ago

With the rework, the step size was defined in the scaled global space and has a uniform step size throughout the volume regardless of scaling.

Before the rework, however, it was defined in the unscaled space and was scaled like the volume, which resulted in fewer steps in the scaled direction for scaling >1.

This PR reintroduces this behavior to keep performance comparable to previous versions.
