In the gl2 library I found routines which are not documented in the manuals, but are very fast: gl_sincos() calculates sin and cos of a angle in about 10 times faster than the math and floating point library. gl_identifymatrix() whichpush and loads an identity matrix. Does anyone has any information about the routines that are in the gl library which is not documented ? ------------------------------------------------------------------------- Homayoon Akhiani University of Illinois at Urbana/Champaign Aviation Research Lab -------------------------------------------------------------------------
