Several 3D tools share a common ROI setup:

ROI

• Position X, Y, Z - describes the center of the ROI

• Angle X, Y, Z - describes how the ROI is rotated

Box

The ROI is a Box (formally, a Cuboid)

• Size X, Y, Z - the cuboid extent in the three directions

The cuboid is centered at the ROI's origin.

Cylinder

The ROI is a Box (formally, a Cuboid)

• Length - the length of the cylinder

• Inner radius - inner radius of ROI extent (if 0, there is no inner limit)

• Outer radius - outer radius of ROI extent

• Cylinder sector start - start of sector from the X/Y plane

• Cylinder sector end - end of sector. If start=0 and end=360, the entire cylinder circumference is used

The cylinder is centered at the ROI's origin, with its center line aligned with the X axis.

Sphere

The ROI is a Sphere

• Radius - the sphere radius

The sphere is centered at the ROI's origin.
