- Perspective (Effect Menu)
-
- DEMONSTRATION AVAILABLE -> `Perspective_Basics.ademo`
-
- DO (Enter, on keypad) Activates Perspective mode. The current custom brush
- temporarily changes into a 4 square matrix that represents the
- boundaries of the brush. The matrix can be rotated in one of 3
- ways: Horizontally on the brush's X axis, Vertically on the Y
- axis, or on its Z axis (Spin). The amount of rotation on each of
- the Perspective axes is displayed in degrees on the right side of
- the Menubar. Once the matrix has achieved a desired position,
- Clicking the Left Mouse button will draw the current custom brush
- into the current perspective.
-
- PERSPECTIVE ROTATIONS The Numeric Keypad is used to control the
- rotation of the brush:.
-
- 7, 8 & 9 control rotation on the X-axis:
-
- 8 rotates the brush so that the top part moves away from you.
- 7 rotates the brush so that the top part moves towards you.
- 9 returns you to zero X-axis rotation.
-
- 4, 5 & 6 control rotation on the Y-axis:
-
- 5 rotates the brush so that the right side moves away from you.
- 4 rotates the brush so that the right side moves towards you.
- 6 returns you to zero Y-axis rotation.
-
- 1, 2 & 3 control rotation on the Z-axis:
-
- 1 rotates the brush in a clockwise direction.
- 2 rotates the brush counterclockwise.
- 3 returns the brush to zero Z-axis rotation.
-
- Rotation occurs at preset increments of degrees. To rotate around an
- axis in larger increments, Hold down the Shift key as you press an
- appropriate key on the Numeric Keypad. The rotation increment
- defaults to 90 degrees when you do this. To set the increment
- yourself, just call up the Gridding Requester while you are in
- Perspective Mode by clicking the Right Mouse Button on the Grid icon
- or by selecting SETTINGS from the Perspective sub-menu. Pressing 0 on
- the keypad resets all 3 axes to zero and fixes the Z-axis (discussed
- below) but retain the apparent distance settings. Pressing Shift
- along with Keypad 0 reverts all the Perspective settings to the
- default state as they were when the program was initially loaded.
-
- CLICKING ANY OF THE DRAWING TOOLS EXITS THE PERSPECTIVE MODE.
-
-
- FILLSCREEN (Keypad - ) Fills the entire screen with the current brush
- in its current Perspective orientation.
-
-
- RESET (Keypad 0 ) Resets the brush to its original state before rotation.
-
-
- CENTER (Keypad . ) Allows you to select the Center of Perspective.
-
-
- SETTINGS Displays the Perspective requester. Also displayable by selecting
- the Grid tool with the Right Mouse button while in Perspective
- mode. The following options are available:
-
- DEMONSTRATION AVAILABLE -> `Perspective_Settings.ademo`
-
- SEE -> `Perspective.pic`
-
- GRID Sets the dimensions for a grid in three dimensional space.
- When the Perspective requester is first opened, the numbers
- in these fields correspond to the dimensions of your brush
- (Z value = Y value).
-
-
- FROM BRUSH - Sets the X and Y grid values to correspond to the width
- and height of the brush, restoring the perspective grid
- settings to the same dimensions as your brush without
- affecting any other settings.
-
- ANGLE STEP - Sets the rotation increment used in conjunction with the
- Shift key when using the Numeric Keypad for perspective
- rotations. The default is 90 degrees.
-
-
- TYPE (OF ROTATION)
-
- SCREEN - Default mode that uses screen coordinates when rotating
- around the different axes. All measurements are angles of
- rotation from absolute zero.
-
- BRUSH - Rotates the brush relative to the current brush
- coordinate system.
-
- DISPLAY Using the Angle and Pos buttons you can choose whether the
- menu bar displays the angles of rotation or the position of
- the brush in 3- dimensional space.
-
- WITH COORDS IN THE PREFS MENU ON, ONLY 2-DIMENSIONAL COORDINATES ARE SHOWN.
- TURN COORDS OFF TO SEE 3D COORDINATES.
-
-
- FIXING AXES
-
- DEMONSTRATION AVAILABLE -> `Perspective_Movement.ademo`
-
- When Perspective is first started, the Z-axis is fixed and the brush cannot
- move through that axis. To change the currently fixed axis:
-
- Press SHIFT 9(on keypad) to fix the X-axis
- Press SHIFT 6(on keypad) to fix the Y-axis
- Press SHIFT 3(on keypad) to fix the Z-axis
-
- The ; and the ' keys move the brush plane forward or back along a fixed
- axis without affecting its current Perspective. Using the Shift key moves
- in larger increments.
-
- The CTRL key temporarily fixes the Y axis so that you can move the brush
- forward or backward in 3D space by moving the mouse forward or backward.
