- BSC is an all-in-one tree growing program. Judging from the description
- of the original program in Analog Computing May 1986, this version has got
- to be 100 or more times faster drawing than the Atari basic version.
- I combined all the programs in the article and added more selective drawing,
- plus a screen save option. A few changes from the original perspec: I
- eliminated range checking in this version, as it isn't necessary for the
- Amiga (the drawing port is so large, the numbers could never get that big).
- This speeds drawing by a factor of 5. I had to redo the branch widening
- algorithm, as something in the original program couldn't be translated to
- Microsoft Basic (good for developing programs, and actually faster than 'C'
- for floating point--without the FFP from Motorola). This version of Bonsai
- now makes use of the FFP library when calculating data
- sets. Use 'save data' from the menu to save the most recently constructed
- data set. Use 'save picture' to save the window in IFF format.
- Other additions and goodies:
- The program incorporates Charlie Heath's palette routine to change the
- default color map. Use 'modify colors' from the Bonsai menu.
-
- A 'color' menu has been added to select the color the next tree will be
- drawn with. This consists of the first 12 colors after the system colors
- (0-3). Default is dark-brown.
- If you modify the default palette with the palette-change option,
- the menu will no longer reflect what's happening on screen, but the order of
- the colors remains the same.
-
- A 'scale' menu has been added to enlarge or shrink the tree images. A range
- of x0.1 (tiny) to x2.0(large) is useful for creating depth in pictures. Use
- a smaller scale for trees in the background. Note: there is no
- hidden-line removal in this, so the foremost tree drawn is the last one
- drawn. Background trees should be drawn first, therefore.
- Default scale is 1.0.
-
- Pointer changes to a tree when you are positioning trees on the screen.
-
- Select 'New Tree' to create a new tree on the screen. Position the tree
- pointer where you want the new tree to go, then click the left mouse button.
-
- Select 'New Picture' from the Bonsai menu to clear the current window.
-
- Pointer changes to a yield sign during lengthy calculations and disk
- accesses.
-
- A dialog window appears when loading or saving data files and pictures.
- Pointer changes to a tree when load has been selected and confirmed with OK.
- Position the tree pointer where you want the loaded data file to be drawn.
