Mapping 3D preview bugs

[peteihis]

• The previewer has a bug, that the wireframe presentation and the rendered presentation don't match. The wire frame appears much larger. (In my test case at least). This remind me of a similar mismatch bug in one GLCanvasDrawer, that was found (and fixed) earlier. (Juts a tgeory, but the may be calculations happening that are actually working around the bug that is no longer there.)

• This is not really a bug, but it is possible to move the preview piece off the image.

Can you still duplicate this with the current version?

OOPS! <-- -->

..So....

The 1st bullet has been fixed.

It is still possible to move the object outside the view and never find it again. (In the AoI mapping previews there is a pop-up menu, but that has not been copied here.)

Also the mouse action depth does not seem to match the depth where the object is, but then the function is different from the usual views anyway: Instead of having the camera rotate around the object here you actually move and rotate the object in front of the camera.

I was mostly concerned about the first point.

The second is less a bug, and more missing signposts. perhaps the field that is shown below the item should have a pattern?

Its been in the back of my mind for a while that all of the mini-preview windows have their own mouse-handling code, when they should probably just re-use Space mode, but that's a separate project.

they should probably just re-use Space mode, but that's a separate project.

I think there is a reason why the preview windows come with mouse handling of their own but it's true there are a few things that could be improved. - For one thing scroll wheel action should be added. I have had a look at those many times but never ended up doing anything about it.
