StarInfo/Whitehouse/!Trees/Text

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

# Icon bar message -
#
IBAR:This is the !Trees application.|MClick SELECT to open the control window.  If a tree has already been drawn, then this will also reopen the picture window.
#
# IB codes are for the icon bar menu -
#
IBIN:Move to the right for information about this program.
IBQU:Click here to quit the program.
SSET:Move to right to save the current settings.
SSAV:Move to right to save the picture as a sprite.
FULL:Select this to display the picture on the whole screen.  Press any key to return to the desktop.
INST:Click here to display the main instructions.
#
#Settings window, and sub-windows...
#
MAMC:This is the amount of surplus memory that Trees currently has reserved.|MThis can be adjusted by dragging Trees' entry in the Task Manager.
MAMN:This is the amount of surplus memory that Trees would need to plot using the current settings.
MACL:Clicking here will cause Trees to claim all the unallocated memory in the computer.
MAXX:Any problems with the settings are listed here.  Plotting can only start when there is nothing here.
MAOP:Click on these to display the four different groups of options.
MADR:Click SELECT to draw the tree(s).  The drawing is performed using the full screen - not in a window.  Once the drawing is complete press any key, and the screen will be restored with the result in a window.

GSHA:Different values will give different shapes of tree.  Unless this is changed, then the same settings will always produce the same trees (but not necessarily in the same places)
GZOO:The overall size of the display.
GTRE:The number of trees to display.
GCEN:If this is on, then one tree will always be at the centre of the picture.  If the picture contains more than one tree, then the others will still be randomly distributed.
GSEP:This is the minimum distance allowed between the trees.  The units are arbitrary.

RSEG:This is the number of segments across the grass pattern.  (In both X and Y directions)
RSGS:This is the physical (horizontal) size of each segment of grass.
RROT:This is the angle that the view is rotated by.  This is most important for the terrain, which is square in shape.
RLEV:This controls whether the trees have any leaves or not.  If this is set to 'Off' then the three settings below are ignored.
RLNO:This is the number of leaves per branch that has leaves.
RLSI:The average size of each leaf.  Individual leaves are random in shape and size.
RLGE:This is the number of LAYERS of branches that have leaves on them.  If this is 1, then only the outermost branches of the tree have leaves.  If 2 then the branches they are connected to will also have leaves, and so on.

BGEN:This is the number of layers of branches, beyond the trunk.  At each layer, each branch splits into 1 or more smaller branches, according to the other settings in this group.
BSPL:This is how many sub-branches occur at the end of each branch.
BMIN:This is the minimum separation between each sub-branch (if there is more than one).
BMAX:This is the most 'turn' that may be applied when going from the main branch to one of its offshoots.
BANG:If the error 'Branch angles too restrictive occurs', then reduce the min. or increase the max.
BSIZ:This is the size of the sub-branches compared to the size of the branch they came from.
BRSR:This is the amount to be subtracted from the two 'Plot as ??? segments' settings in Trunk section at each split.  If this is >0 then it means that the outer branches are plotted using fewer polygons. (Saving memory & time).

BLEN:This is the actual length of the trunk.
BDIA:The diameter of the trunk.
BRED:The dimension for the first set of branches is this multiplied by Size scale (under Branch splitting).

BSEG:The number of polygons to use when plotting the trunk.
BSLN:A - along the trunk.
BSAR:B - around the trunk.
BSRR:Further branches use these values, with the 'Resolution reduction' subtracted at each generation.

sTYP:Type in the name here, and drag the picture in order to save.  To resave using the same name, just click on OK.
ssOK:When resaving click here.  When saving for the first time, you will need to drag the picture to a file window in order that Trees knows where to save.
sSPR:Type in the name below, and then drag this to filer window that you want to save into.  (Or drag this onto another program to save direct to that program).
