element generates a circular surface with a diameter of 1, lying in the X-Y plane and balanced around the coordinate system origin. The complexity (i.e. the number of the circle divisions) is determined by the complexity of object
element. For every 16 object complexity degrees 1 supplementary stripe is added (interstage). The normals located in the circle vertices are (0, 0, -1). The texture coordinates in the vertices correspond the area texture location on the circle surface. The circle is oriented in the negative Z axis direction, i.e. facing the default camera
. The element returns the identification number
of the created circle.
As a default, the circle is visible from the front side only. Its visibility is changeable by the visible object side
