[Bug 122656] New: Rotation of 3D scene is less smooth than before
https://issues.apache.org/ooo/show_bug.cgi?id=122656
Bug ID: 122656
Issue Type: DEFECT
Summary: Rotation of 3D scene is less smooth than before
Product: Draw
Version: AOO400-dev
Hardware: PC
OS: Windows 7
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: editing
Assignee: issues@openoffice.apache.org

Document with torus to rotate
Open the attached document.
Make two single clicks on the torus to switch to rotation mode.
Drag the right middle handle up and down. Try up and down with sudden stops.
In older versions the rotation is smooth. In newer versions it rotates
unevenly. Especially when you stop, you will notice an additional movement
after stopping.
If you are not familiar with the movement, you might not notice it. So please
compare a new and a old version of AOO to notice the difference.
>From the builds, which I still have, the version r1432130 is OK, and r1439888
shows the unevenly rotation. You can compare AOO 3.4 to the current AOO 4.0
snapshot as well to see the defect.

ALG: D'accord. Anyways, the direction will be to have a direct 3D renderer one
day...

Seems to be a really small difference, I compared "AOO 4.1.0-Dev – English UI
/ German locale - [AOO410m1(Build:9750) - Rev. 1516435 2013-08-24]" on
German WIN7 Home Premium (64bit)", own separate user profile with 3.4.0 (and
3.4.1), I did not see an absolutely certain difference

Hi Armin, it does not help. I suggest to adjourn the bug till AOO4 is released
and AW080 is rebased and I can test it there.

test patch for vcl
ALG: Hi Regina, I checked but the paints are as they ever were; using old VCL
paths. Especially for non-scaled, non-roated bitmaps (as for the 3D stuff) this
is taken to not do unnecessary conversions. I have switched this off with the
added patch, could you try if this makes it better, please? This would be my
best current clue.

ALG: Hard to say, there is no objective measurement. Works pretty well in my
version. Since the 3D renderer did not change, probably some other stuff in
user input handling and timing may have changed. Have you tried with sidebar
on/off, maybe the object gets e.g. selected each time a change happens and the
sidebar completely refreshes or something similar, that would be a good hint.

My first thought was the sidebar too. But switching off sidebar makes no
difference and the version r1439888, where I see the defect first, is before
sidebar integration.
"Since the 3D renderer did not change"? r1439888 belongs to bug 121532, with a
lot of changes for drawing. But you knew better, whether those might have an
influence on the performance.
Please try it with a not too fast CPU. For me the additional movement after
stopping the mouse is obvious. There is some delay between mouse movement and
reaction on screen. If you use an older netbook, you have to switch off the
lines, otherwise the display will jump in all versions, because rendering the
lines is too expensive.
r1432130 (OK) was 11.Jan., and r1439888 (bad) was 29.Jan., so in that time
range something has changed.
