How to vary viewing condition?

Setting diamond position

DiamCalc allows to easily reposition the diamond with the mouse to view it from a different angle. To do this, press the left mouse button anywhere on the image:

Note the position of the mouse cursor above - it is the place where mouse button was pressed. To move the diamond, simply move the mouse in the direction where you want to rotate it, holding the button. After diamond is moved to the desired position, release mouse button. On the screenshot below, mouse cursor is where the button was released:

As you see, moving the mouse in vertical direction looks like "dragging" the diamond around horizontal axis. Moving the mouse in another direction would cause a different rotation. Such operation can be repeated, and the diamond can be set to any position after several steps.

There is another tool for moving the diamond: the movement panel. It can be called by Movement panel command in View menu. The movement panel allows to specify by which angle the diamond should be rotated, and perform the rotation by one of six buttons (one for each direction).

Setting one or two simultaneous views of a diamond

DiamCalc can show two simultaneous views of the same diamond taken from different angles. To do this, use Split command in View menu. A horizontal bar will appear, letting to split the diamond image into two panes.

When there are two images, each one can be tuned separately: e.g. one can hold a frame model of the diamond and the other view can be a photoreal model.

A split line between two models can be moved at any time by mouse, changing sizes of the images. Also, two images can be converted back to a singe one by moving the split line to the top or to the bottom, decreasing the size of one image to zero.
