- 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.
