=== Locators ===

The origin locator (shadow_x_ori, shd_x_ori1, shd_x_ori2, etc) defines the upper boundary, center, and direction of the shadow volume. This locator should generally always be oriented so that it points down (i.e. rotated so that the locator '''+y''' points in global '''-Z'''). The corner locator (shadow_x_crn, shd_x_crn1, shd_x_crn2, etc) defines the width, length, and lower boundary of the shadow volume.
