Instructions for the Simple 3D Editor Ben Discoe, 3/2/90
Command line options:
'-m' will bring up the editor in Medium Res (~640x200). However,
since the pixels are far from square, you must remember that shapes
which look normal in medium res will appear squashed when displayed
in 3D.
'-pnnn' will allow a maximum of nnn points in memory.
'-lnnn' will allow a maximum of nnn lines in memory.
'-snnn' will allow a maximum of nnn points to be selected at once.
Moving the 3D cursor:
You may have noticed that the Amiga mouse and monitor have a curious
limitation, specifically that it can only display two dimensional data.
The "cursor" in this editor exists in 3D. The third dimension can be
adjusted with
'8' : move the cursor away from you
'2' : move the cursor toward you
Selecting points:
The first and second mouse buttons can both be used to select points,
although each in a different way. The left mouse button will select
the point closest ON THE SCREEN to the on-screen pointer, while the
right button selects the points closest IN 3D SPACE to the 3d cursor.
The second mehtod is useful for selecting points "behind" each other.
What the buttons do:
» 3D « Selects 3D mode, in which you view (not edit) your data. If
everything looks upside down IT'S NOT MY FAULT :)
ADD: Selects ADD point mode. Click either button to create points
in 3D space, at the current location of the 3D cursor. If the
editor refuses to add points, it is because you have reached
the maximum points allowed.
MOVE: Selects MOVE point(s) mode. Select a point with either button
(hold down SHIFT for multiple points). Once the point(s) are
selected, you can drag them in any direction. UNDO can be used
to undo/redo a move.
DELETE: Selects DELETE point mode. Click either button to delete the
nearest point. The editor will not let you delete points that
are part of lines.
LINE: Select START LINE mode. Click on a point to START a line. This
will put you in LINE POINT mode.
(LINP): Shows you if you are in LINE POINT mode. Click points to add
them to the current line. UNDO can be used to take back line
segments. The editor will not allow you to join points to
themselves, and will stop you when you run out of room.
DELINE: Selects DELETE LINE mode. Select points that are on the line that
you want deleted. As soon as the points specify a line uniquely,
that line is deleted.
UNDO: Can be used to take back either a line segment (LINP) or a move
operation (MOVE).
XY: selects a "TOP" view
XZ: selects a "FRONT" view
YZ: selects a "SIDE" view
COPY: If there are points selected in MOVE mode, this button will make
a copy of them. Click and drag the mouse to move the copy
somewhere else.
NEW: Wipes out everything. WARNING: does not ask you if you're SURE.
SAVE: Saves all points and lines to the file "data.3d"
LOAD: Loads all points and lines from the file "data.3d"
QUIT: Quits. WARNING: does not ask you if you're SURE.
(color) Selects which color the NEXT line you create will be. Changing
color in the middle of a line has NO effect.
What the keyboard does at all times:
'c': toggles the crosshairs on the cursor.
Esc: Quits. Exactly like hitting the QUIT button.
During Editing:
'w': select XY (top) view,
's': select XZ (front) view,
'd': select XY (side) view. These will switch immediately without
setting the third dimension to zero, which makes them useful when
used with the second button.
'u': UNDO. Same as the UNDO button.
'8': move the 3d curosr away from you.
'2': move the 3d curosr toward you.
During »3D« view: The entire keypad lets you change angle of view. Watch
the numbers at the top of the screen to see their effect. '5' will
toggle the polygons filling for closed lines.
