Viewer Navigation

All 3-D viewers in ElumTools utilize the same navigation commands. Currently this applies to the Photometric Web viewer in the Light Source - Source Position tab in Luminaire Manager and the Calculation Viewer (rendering). When you close the Calculation Viewer (rendered view) your last know settings will be retained (font, size, color, viewpoint, pseudocolor and more).

(See in more detail below)

Interactive command operations:

Zoom The Zoom command changes focal distance, which enlarges or decreases the image size continuously as the mouse is held down and dragged, or as the mouse wheel is rolled back and forth. The observer focus position is always the center of the screen.
Orbit The Orbit command moves the observer around the model while maintaining the same focus point. Imagine that you are a spaceship orbiting the earth, always looking at the center of the earth.
Walk

The Walk command combines the Dolly, Pan and Rotate commands into one movement. Dragging the mouse up/down moves the observer forward and backward. Dragging the mouse left/right, rotates the observer view position left and right.

 

Using the Shift and Ctrl keys in conjunction with dragging or the arrow keys invokes the Rotate and Pan commands as well.

See Dolly, Pan, Rotate
Dolly The Dolly command moves the observer and the focus point in and out of the model along a straight line. Depending on the view direction, from the observer’s point of view, this feature allows you to “walk” into and out of the space.
Pan

The Pan command moves the observer and focus point relative to a fixed model position. Imagine that you are looking straight ahead and moving laterally left/right or up/down. The image will move opposite to the panning direction; sliding the mouse to the right moves the image to the left.

 

Pressing and holding down the mouse wheel also invokes the Pan function. In this case, sliding the mouse to the right slides the image to the right.

 

Holding down the Ctrl key when using another command invokes the Pan function, overriding the current command.

Rotate

The Rotate command allows the observer to look left or right and up or down from a fixed position. Use this command when you are in a space and want to look at different surfaces without changing position. A panorama view is obtained by moving constantly to the left or right.

 

Holding down the Shift key when using another command invokes the Rotate function, overriding the current command.

Clip The Clip command cuts away the front plane of the image continuously to reveal the objects within and beyond. The size of the image does not increase or decrease. This command is very useful when viewing an image with exterior and interior components. The clip distance specifies how far away from the eye position the image will be truncated.
