Fortunately theres a solution known as polygon reduction. If aesthetics aren’t a concern, then something like this might work. Some tools like ZBrush can quickly create a high polycount, so its easy to run into this limit. Regardless of what you do programmatically, I believe you will find the results to be absolutely horrible. You could merge vertices that are within a certain distance of one another. You could implement something like Decimate in your code, but there’s a reason modelers don’t use Decimate. You can create normal maps and such this way. The best option is to model it with the right number of vertices in the first place, save that version, and then increase the vertices if you need a second version that has a lot more vertices and save that version. The software allows for processing and repair of polygon meshes arising in 3D scanning. MeshLab, a software originally developed by the university of Pisa, is now being enhanced by the two italian institutes ISTI and CNR. You can probably google something like “Blender reduce poly count” and find something for whatever modeling tool you are using. The open source software MeshLab allows for display, processing and repair of polygon meshes of 3D models.

This YouTube video describes how to do it in Blender. Otherwise, you’re probably going to be removing the extra vertices by hand. If you just need to get your vertex count down for a test or something Blender has the Decimate modifier. Where your vertices are placed is not a decision best left up to machines. Although, in my limited experience this is a bad idea. I’m not really a modeler, but I’m pretty sure all modeling programs have a way of reducing the poly count.
