How do get more calculating speed?

Hello, I have a theoretical question. I'm working on something like 3d sculpting application, so, there is a lot of 3d triangles. When my sketch contains more than about 1500 triangles, it begin to move slowly, I guess the reason is that it is hard to calculate a big number of triangles. But I want to work with hundreds of thousands of triangles. Is there a possibilities to get more calculating speed in Processing? Or this kind of applications require a low-level development for example on C++ and OpenGl ?



  • Answer ✓

    Are you calculating the triangles in every frame (beginShape(); ... endShape();) or are you saving them as a PShape object?

        PShape shape;

    Using a PShape object to store the 3d model and only recalculating it on changes should theoretically improve performance.

    You can also try to visualize only the visible part of the 3D model.
