I have a VB6 engineering ap that rotates and pans a 3D wireframe of up to 10,000 lines. All rotation code and maths is done in program, and the display draws an array of pre-calculated XY points using line drawing in GDI
I really want to convert this ap to VB 2005, but all the tests I've done using GDI+ methods show speeds of only 20% drawing lines compared to VB6. This will be unacceptable to show smooth rotation and panning.
Is there anything I can do to speed this up (GDI API calls, DLL's etc)
