Fit Window

Scale the surface to be rendered within the viewing window.

Orbit Mode

Using this mode, the surface can be rotated much like a model in a CAD program.  

NOTE:  Holding the Shift key down while dragging the mouse will allow you to change the Z scaling in any view mode.

Turntable Mode

This is the classic TrueMap rotation mode.  Moving the cursor left/right rotates the surface around its center.  Moving the cursor up/down changes the Z scaling.

Zoom Mode

Using this mode, the surface can be moved closer or farther by dragging the mouse up or down.

Zoom Box Mode

This view mode allows you to select a rectangular region of the display to zoom.  Notice that the location of the crosshair in the center of the zoom box will be the center of the new "zoomed" window.

Pan Mode

The Pan mode allows you to drag the surface data horizontally and vertically through in the viewing window.

Z Scale Mode

This mode allows you to change the Z scaling of the surface to exaggerate details.

XY Top View

Selecting this option orients the surface so that you are viewing it directly from above.

Front Top Right View

Selecting this option orients the surface so that you are viewing it from the front top right.

Front Top Left View

Selecting this option orients the surface so that you are viewing it from the front top left.

Back Top Right View

Selecting this option orients the surface so that you are viewing it from the back top right.

Back Top Left View

Selecting this option orients the surface so that you are viewing it from the back top left.

Display All Profiles

This option will display all of the profiles extracted along the surface in the selected direction.

Display Average Profile

This option will display the average profile computed from all of the profiles extracted along the selected direction.

Display Envelope Profiles

This option displayed the profiles that enclose the surface in the selected direction.

Display Cursors

This option shows/hides the two cursors.  These cursors can be used to compute the precise location of a point on the profile.  To move a cursor, move the mouse pointer until it is on the cursor line.  When the mouse pointer changes shape to the left/right arrow, hold down the left mouse button and drag the cursor to the target location.

Resize Cursor Width

This option places the profile display into a mode where the width of the cursors can be changed.  After clicking this option, move the mouse pointer to the cursor and drag the cursor width to the target width.

Reset Cursors

This option resets both cursors to a single sample in width.

Gradient

This option renders the surface using the currently selected legend gradient.

Reflective

This option attempts to render the surface as if it were a shiny reflective surface.

Solid Color

This option allows you to select a specific color to use when rendering the surface.

Filled

Renders the surface as filled polygons.

Wireframe

Renders the surface as a wireframe mesh.

Samples

Renders the surface data points (samples) only.

Mesh

This option renders lines along the rows and columns.  The distance between the grid lines is automatically determined depending on the current zoom level and sample spacing.

Render Axes

Render the axes labels.

Contours

Render contour lines (or iso-lines) to more easily visualize the slope of a surface.

Render Shadow

Render a fake shadow beneath the surface to help visualize the depth of the surface.

Silhouette Lines

Render silhouette lines to enhance the features of a surface.

Render Side Walls

Render walls (sometimes referred to as a skirt) around the edges of a surface.

Above

Render the surface projected above the 3D surface to aid with the visualization of the surface.

Below

Render the surface projected below the 3D surface to aid with the visualization of the surface.

Contours

Render contour lines on the projected surfaces.
