Zoom not working properly? #61

Closed raoulteeuwenPE closed 1 year ago

raoulteeuwenPE commented 3 years ago

Expected Behavior

Some natural way of zooming to a certain part, and unzooming. Also maybe improve how the zoomed-in image pans compared to ones mouse movement

Current Behavior

When i zoom, i don't have an idea how to control where it is zooming. Also, with the db's i work with, when zoomed in and trying to scroll to the part that is invisible, the area i can scroll in 'cuts off' while only showing a part of the total visualization, making it impossible to reach the non-shown part. Also, when using the mouse the screen behaves unexpected, like it is trailing in my mouse movement or planning curved paths through the zoomed in image.

Possible Solution

Not sure whether i don't know how to use it. Would love it if one can, while zoomed out, position the mouse cursor at some point in the visualization, and than scroll-wheel zooming in at the part your cursor is at

Steps to Reproduce

  1. Open db with for instance 126 tables
  2. Start visualizing it
  3. Try to zoom in at a section
  4. Find out navigating in the zoomed-in image is unintuitive (strange curved paths of how the zoom behaves/pans), you don't have control of where you're going to zoom in, and zoomed-in-image, when panning to edges, is cut off from (unable to reach all parts of) total zoomed out image.

Context (Environment)

Detailed Description

I hope the above describes my experience and expectation enough

Possible Implementation

? But please enjoy your parental leave first ;-)

I can reproduce this:

  1. Big Schema
  2. Zoom in
  3. Scroll (via mouse clicks) to the right.
  4. Right side is cut off (and you can't scroll further)
