Query and set the cylinder roundness.
void gleSetNumSides (int nslices); int gleGetNumSides (void);
positive integer number of slices
Query and set the GLE cylinder and cone roundness. When GLE draws a cylinder or a cone, it approximates the circular cross-section with a polygon (of 20 sides by default). These subroutines can be used to change the default number of sides in this cross-section. A smaller number of sides can typically be drawn much faster, at the loss of some visual accuracy. Increasing the number of sides to more than 20 will typically have no noticable visual effect.
Multiple threads using GLE share a single global number of sides (although this should be easily fixable because GLE does use a centralized graphics context).
