"OPTIMIZE ModelName"


            This command optimizes a 3D model loaded with the LOADNEW command. The 3D model must have been one of the following formats:


            .STLA   -           STL ascii format

            .STLB   -           STL binary format

            .STL     -           STL format (control determines whther ascii or binary)

            .STLE   -           STL Enhanced format (binary)


            Once a Model is Optimized you can not reverse the process (does not effect your original model file though). Optimizing takes some time and for very large models (ie. 100,000 triangles) it could take a few seconds.


            An optimized model is converted into an internal format that lends itself to vertex arrays, which simply put is a faster way of drawing 3D models in OpenGL. Cheaper video cards/chips may not see a big increase in speed when optimized (or may even slow down), but on better video cards you may see a significant increase in drawing speed (possibly 25% or better). If an optimized model in also Locked (LOCK command), you will see even better speed in drawing, on better video cards).


            You can though save a model, once optimized so it is in its optimized format and then reload it. Optimized models are saved with the EZ3D file extension.
