This provides an alternative way of everting the sphere, instead of pressing space. * , / : Multiply,divide time step delta_t by 2. This changes the speed at which the eversion is performed. tab & : Cycle through polygons/checkered polygons/bands/points s : Toggle smooth/flat shading b : Toggle backface culling f : Toggle which faces are front facing r : Cycle through rotation modes c : Cycle through color channels front face & back faces (/) front face (0), back face (1) background (2), text(3), panel(4) page up/down : Increase/decrease total number of strips right/left arr. : Increase/decrease number of strips displayed up/down arrows : Zoom in/out end : Toggle display of lower hemisphere home : Toggle display of half-strips 1-8 : Select predefined colors 0 : Darker color 9 : Lighter color closely derived from the original code by Michael J.
