Front/back/left/right/top view buttons now switch display to orthographic mode. Default view button and mouse drag restore perspective mode.

Scroll to zoom does not behave as expected in orthographic mode (appears to affect clipping plane).

Transition between orthographic/perspective should attempt to maintain similar apparent zoom.

5c745f1 fixes ortho extent to work with different bed/canvas proportions

anoved commented 10 years ago

eba892f now uses viewpointZ instead of bed size to calculate ortho extent scale. Bed no longer snaps to fill canvas in ortho mode but ortho view zoom works and corresponds well with perspective zoom.

Switch back to perspective should occur on rotation but not panning.

e796977 mouse move restores perspective only if not panning

Zooming in too close clips model display - more pronounced with taller models. Limit minimum viewpointZ to model height in orthographic [top] view?
