3D Properties

Properties shows the numerical values of the current 3D view using a dialog.

Select 3D > View > Properties

You can setup the 3D view in terms of an eye position and direction. The direction is specified using an angle and elevation.

You can also set the perspective angle or cone of view, and control the various 3D modes.

This command allows you to see and change how the graphics are drawn, and also the viewing parameters (eye location, angle, elevation and cone of vision).

Graphics

1. Wireline

Check the Wireline tickbox to make any drape present invisible. This allows you to view your data using a wireline model. Uncheck the tickbox to make the drape visible and your model displayed with solid colour.

Wireline on: 

Wireline off: 

2. Smooth shading

The following diagram shows the different combinations of the Smooth property and the Smooth shading options for the display of TINs.

3. Texture mapping

Texture mapping allows you to make a draped image invisible and to view your model with solid colour.

Texture mapping on (tickbox checked):

Texture mapping off (tickbox unchecked)::

Lighting

Check the Lighting tickbox if the items should be lit by a directional light in the 3D window.

Generalisation - Coarse ..... Fine

The slider controls the level of faceting for curves, e.g. for drawing circular Polygons in a 3D Window.

The faceting is also sensitive to other parameters such as model extents, and the distance from the Eye point to the Look point.

Eye

Sets the current eye position, i.e. where to look from.

Angle

Sets the viewing angle, about the vertical (Z) axis.

Elevation

Sets the viewing elevation, above or below the XY plane.

Cone

Sets the perspective viewing angle.

Light Tilt

Tilts the 3D light.
