- Release Notes for LandScape V1.0
- ================================
-
- V1.0 of LandScape has been released with the following known bugs or
- deficiencies. None of these should affect you during normal usage of the
- program.
-
- 1) The depth-arranging algorithm is not 100% accurate. This is the part of
- the program that sorts out the order that plants are draw, so that plants
- that are closer to the viewpoint are drawn last, so that they overlay the
- ones behind. I have picked a very simple way of doing this, and it works
- surprisingly well, but not perfectly, in particular at low elevations
- (20 degrees to 40 degrees) in conditions where very tall objects are
- close to very small ones.
- 2) When rotating the garden at low elevations (20 or 30 degrees), a
- rectangular garden appears to elongate as it approaches t1=90 degrees.
- The visual impression is that the elevation is increasing. In fact, the
- graphics routines are correct, but the aspect ratio of the screen gives
- rise to this illusion. I may introduce some vertical compression (take
- account of pixel aspect ratio) if this bothers people.
- 3) The drawing routines assume that all garden objects are contained inside
- the garden boundary, although the program will allow you to draw outside
- of it if you wish. Under certain rare circumstances, however, drawing
- outside of the garden boundary will crash the program, and so you are
- strongly advised not to do this.
- 4) Since the plants are drawn mathematically, they look best at reasonable
- viewing distances. If you zoom in VERY close to a plant, it will not look
- nearly as good.
- 5) Since the drawing routines use single precision FFP numbers, if you spin
- the garden around a lot when selecting a viewpoint, you may find that
- rounding errors start to accumulate, and the garden will do something
- strange (like maybe slide off the screen). I have never tried this, and
- never seen it happen in normal use, but you have been warned.
- 6) The coordinates on the 'what is' requester are a bit anachronous.
- 7) If two or more objects are placed at identical coordinates, it is only
- ever possible to 'select' one of them.
