Toolbar and Panels

The Viewport Properties panel manages viewport properties.

Viewport

Title

The viewport title displays in the top left corner of a viewport.

Size

The viewport height and width in pixels.

Projection
Parallel

Sets the viewport to a parallel projection.

Parallel views are also called orthogonal views in some systems. In a parallel view, all the grid lines are parallel to each other, and identical objects look the same size, regardless of where they are in the view.

Perspective

Sets the viewport to a three-point perspective projection.

In a perspective view, grid lines converge to a vanishing point. This provides the illusion of depth in the viewport. Perspective projection makes objects farther away look smaller. All three directions converge to a point.

Two-point perspective

Sets the viewport to a two-point perspective projection. This means that the z direction will not converge to a vanishing point.


Parallel projection (left), 3-point perspective projection (center),
2-point perspective projection (right).

Wallpaper

Wallpaper is a bitmap that displays behind the grid in a viewport. It does not change when you zoom, pan, or rotate your view.

Filename

Displays the wallpaper file name.

Click Browse to select a file.

Show

Shows or hides the wallpaper.

Gray

Displays the wallpaper as a gray image rather than color.

Rhino stores the wallpaper bitmap image in the Rhino document file.

Camera

The camera is the x,y,z position of the viewpoint or eye point.

The target is the x,y,z position in space that is at the center of the viewport and about which the view rotates.

Each viewport has its own camera.


Camera (1) and Target (2) shown with Camera command.
Lens length

When the projection is set to perspective, you can change the lens length of the camera. A "normal" lens length for a 35 mm camera is 43 to 50 mm.

Rotation

Sets the rotation of the camera about the camera axis (the line between the camera and target).

X location

The camera x location in world coordinates.

Y location

The camera y location in world coordinates

Z location

The camera z location in world coordinates

Target

X location

The target x location in world coordinates.

Y location

The target y location in world coordinates

Z location

The target z location in world coordinates
