Embodiments herein may relate to a technique to be performed by surface partition logic. The technique may include identifying a first mesh portion that is related to a first plane of a three-dimensional (3D) space, and a second mesh portion that is related to a second plane of the 3D space. The technique may include identifying, based on a linear representation of a border between the first mesh portion and the second mesh portion, an element of the first mesh portion that at least partially overlaps the second mesh portion. The technique may further include altering the element of the first mesh portion to reduce the amount that the element overlaps the second mesh portion. Other embodiments may be described and/or claimed.
