I have 1000 surfaces to be trimmed in my project. according to the glu1.3 defined some callback function which could be used return the trimming result back to the program. so i put these result into displaylist in my program. but rendering these trimmed surface with displaylist seems not enough quickly when i rotate these surface with mouse. i want to know how could i make the rendering more quickly?
when gluEndSurface(theNurb) is called, The trim operation do well in most of surface but there are a few trimming operation which poped up message box like Run-Time Check failure#0 The value ESP was not properly saved across a function cal. bra ..bra....How could i solve this problem? thanks
