This is part of a new series of videos covering Projects and Design using the PowerBasic Windows compiler. These videos may be longer than the Snippet videos as they cover projects in detail.

This project is to create simulation of a globular cluster within a graphics window, and illustrate the migration of four civilisations over time to the stars.

Today we are optimising the code for writing to the graphics window, to give us more frames per second and allow more stars to be processed.

0:00 - Introduction
00:50 - Working out the baseline
02:19 - Optimising for speed
10:21 - Testing

12:44 - Summary

I don't work for, nor am I paid or sponsored by, the owners of PowerBASIC, I'm just a fan of their products.
