Threhold

In this mode, you select the threshold value used to compute the surface of your model.


	Threshold = 20	Threshold = 50	Threshold = 75	Threshold = 100

From the Graphic Interface

Threshold

You can select the threshold value. The range is from the smallest to the largest voxel values in the dataset.

Note:

Pressing the "Scroll Lock" key while the cursor is over the slider will lock/unlock the slider. The slider's value can not be changed while it is locked.

From the Display Area

You can use the mouse wheel to change the value of the threshold value. The change will be of 1.0 per click.

From the Keyboard

The following commands can also be mapped to keyboard keys as a shortcut:


	Key map	Action

	a	Decrease the threshold value by 1
	s	Increase the threshold value by 1
