Description
Fixes #3792
Adds a mode which translates lookat rather than eyeposition, avoiding the camera getting moved inside a shape. To avoid the center of rotation changing the pr adds a
static_lookat
. It is used as the center of rotation and ignores translations done by zooming. The resulting behavior depends on other settings:cad = true
the cameras lookat is held on the connecting line between eyeposition and static_lookat. This should lead to different rotation speeds when zooming but nothing jarring.cad = false, zoom_shift_lookat = true
(default) lookat and eyeposition get translated, leading to rotations no longer being centered at the screen center. This becomes more messy when translating the camera, as that translates static_lookat too, i.e. it keeps the pivoted rotation.zoom_target = :lookat
things should continue to work as they did beforeType of change
needs some more testing to be sure it's not breaking...
