[Bf-committers] Dolly bug

[Juhana Sadeharju]

In Blender 2.4.5. Test yours.

User preferences are "dolly", "turntable", "around selection".

First I moved the selected cube to far corner of the ground plane:

Then I scrolled (dolly) forward.
The problem is that I cannot go nearer the cube than this:

Please check Construction Set of Morrowind/Oblivion/Fallout3
for how the dolly should work. Blender has now some kind of
invisible barrier which cannot be passed; that is wrong and
odd.

Possible problem: Blender calculates the distance to origin,
not to the selected object.
(Actually the distance to the plane which goes through the
world origin and has the center view ray as normal. When
that distance goes to 0, the view stops as shown.)

When the turntable is implemented around the selection, the
distance should be calculated from the selection.

The wrong code must be in the dolly code because the rotation
around the object is performed correctly.

Note: Construction Set's dolly will additionally go beyond
the selected object (distance goes negative). Blender should
have that kind of dolly as well because it is most flexible
and usable.
(In CS, how the rotation goes after view goes beyond the object?)
