# Display 3D GUI Buttons

The user interface of the Display 3D webpage element contains the following buttons:

Button | Description
| Fits the 3D point cloud to the display. The point cloud will automatically scale to be maximally displayed in the viewer. The original aspect ratio of the point cloud is also maintained, therefore it may not fill the viewer completely.
| Changes the view to display the point cloud on the Y and Z-axes, in a reverse X-axis direction (in other words, shows the point cloud "from the left").
| Changes the view to display the point cloud on the Z-axis and a reverse Y-axis, in an X-axis direction (in other words, shows the point cloud "from the right").
| Changes the view to display the point cloud on the X and Y axes, in a reverse Z-axis direction. In other words, this view shows the point cloud "from the top", from the perspective of the camera sensor.
| Change the view to display the point cloud on the Y-axis and a reverse X-axis, in a Z-axis direction. In other words, this view shows the point cloud "from the bottom", with the perspective aimed toward the camera sensor.
| Changes the view to display the point cloud on the Z-axis and a reverse X-axis, in a reverse Y-axis direction. In other words, this view shows the point cloud "from the front", and the orientation on-screen is as if looking at the inspected part facing from camera-to-laser in front of the 3D vision system.
| Changes the view to display the point cloud on the X and Z-axes, in a Y-axis direction. In other words, this view shows the point cloud "from the back side", and the orientation on-screen is as if looking at the inspected part facing from camera-to-laser behind the 3D vision system.
| Changes the view to isometric, with all three coordinate axes appearing equally foreshortened, and the angle between any two of them being 120 degrees. This is the default perspective.
| Switch between the Point Cloud and Surface rendering modes: : Switches to Points mode. In this mode, each pixel of the acquired 3D cloud data is rendered as a separate point. : Switches to Surface mode. In this mode, the 3D cloud constructed from the acquired data is rendered with contiguous surfaces. This is the default rendering mode.
| Switch between Orthographic and Perspective modes: : Switches to Orthographic view. In this mode, all principal axes and planes of the point cloud are parallel with the projection plane, and lines of the same length all appear equal. In this view, there is no vanishing point, and parallel lines never touch. This view therefore makes it easier to compare various areas (for example, multiple objects) of the point cloud, as there is no viewpoint and/or distance distortion. : Switches to Perspective view. In this mode, closer areas of the point cloud appear bigger, the vanishing point exists, and parallel lines of the object(s) touch at infinity. As such, this mode provides a better sense of depth. This is the default setting.
| Enables the Z-Axis Height Color Map and the Color Map Legend, indicating the height of the point cloud points along the Z-axis, relative to the height coloring setup in the Spreadsheet Editor.
Point cloud with color mapping disabled | Point cloud with color mapping enabled
When color mapping is enabled, the warmer the point is, the closer it is to the top threshold (i.e., it is "higher" in the working space of the sensor). Consequently, the colder it is, the closer it is to the bottom threshold (i.e. the lower it is in the working area of the sensor). This setting is enabled by default, indicated with a lighter gray background on the button.
| Switch between the available lighting modes of the 3D scene. : Enables ambient directional Lambert lighting. When this mode is active, lighting is cast from the perspective of the 3D viewer camera. This is the default setting. Tip: When Lambert lighting is active, this button has a lighter gray background, as shown below. : Switches from Lambert lighting to topside lighting. When this mode is active, lighting is cast from the Z-axis. Tip: Enable or disable this setting based on which features of the acquired point cloud you wish to be visible.
