The purpose of this tutorial is to demonstrate the basics of using height fields in Povray. I
hope that by sharing my knowledge with you, I can help you develop your skills and give you ideas
that you can benefit from in your own projects. The reader should also read the official Povray documentation.
The official documentation contains information that this tutorial doesn't and you will definitely want to
refer to it as you experiment.
This tutorial is written primarily for beginners. You must, however, know how to create and render basic scenes in Povray. If you have tried a few of the simple examples from the Povray documentation, played around with them and created a few of your own, you should have little or no trouble understanding the concepts here.
That's it for now. I will be adding more material as/when time permits. I hope this tutorial has been an aid to your understanding of height fields.
