Three-Dimensional Plot Window Help

  

Using the 3-D plot window, you can display and manipulate a Maple plot3d data structure. The 3-D plot window is invoked by using the plotsetup(maplet) command, followed by a plot command. For example,

plotsetup(maplet):

plot3d(x^2*cos(y), x=-2..2, y=-2*Pi..2*Pi);

  

The plot window contains menus that allow you to change attributes of the plot3d structure. For more information about the plot3d structure, see the ?plot3d and ?plot3d,options help pages.

File Menu

  

The File menu allows you to export the plot and close the plot window.

  

To create a file containing the 3-D plot:

1. 

From the File menu, select Export.

2. 

Select a file type: Postscript, GIF, JPEG, POV, or DXF.

3. 

Specify the output filename.

  

The file is saved in the root folder of your Maple install. For example, in Windows, this is by default C:\\Program Files\\Maple.

  

To close the plot window:

• 

From the File menu, select Exit.

Style Menu

  

From the Style menu, you can select the display style of the surface.

• 

Surface with Wireframe fills the regions and displays grid lines. This is the default style.

• 

Surface fills the regions, but does not display grid lines.

• 

Surface with Contour fills the regions and displays contour lines.

• 

Contour displays the level curves of the surface.

• 

Wireframe displays only the grid lines over a transparent surface.

• 

Wireframe (Opaque Surface) displays only the grid lines over an opaque surface.

• 

Point displays only the points calculated.

  

Using the Style menu, you can select values for other options.

• 

Line Width controls the thickness of line plots and polygon borders.

• 

Line Style specifies the pattern used when drawing line segments.

• 

Point style specifies how the points are drawn when you select the Point style, for example, Diamond.

• 

Grid Style specifies the type of grid lines. Triangular displays a triangular grid while Rectangular omits the diagonal to form a rectangular grid.

Color Menu

  

From the Color menu, you can select the color for the plot.

• 

XYZ shading varies the red, green, and blue values (RGB value) independently with the x,y and z-coordinates of the surface. This is the default color.

• 

XY shading varies the green and blue values with the x and y-coordinates of the surface.

• 

Z shading varies the red and blue values with the z-coordinate.

• 

Z (Hue) varies the color with the z-coordinate.

• 

Z (Grayscale) varies the shade of gray with the z-coordinate.

  

From the Color menu, you can select a lighting scheme.

• 

Light Schemes 1 to 4 are preselected light placements.

Axes Menu

  

Using the Axes menu, you can select how the axes are drawn.

• 

Boxed places the axes along the bounding box of the image and draws the bounding box.

• 

Framed draws the axes along the bounding box, but does not draw the box.

• 

Normal causes the axes to intersect at zero values when possible. Otherwise, the axes intersect at a minimum value on any axis.

Projection Menu

  

Using the Projection menu, you can select one of the two scaling styles.

• 

Unconstrained scales the surface to fit the window. This is the default behavior.

• 

Constrained shows the true scale of the surface. The scaling can also be specified using the scaling option to the plot3d command.

Transparency Menu

  

Using the Transparency menu, you can select the transparency of any surfaces (not lines) in the plot.

  

A transparency of 100% is nearly equivalent to use of the Wireframe style. Transparency is 0% (opaque) by default.

The Help menu opens this help page.
