Overview of this book

Blender is by far the most popular open source graphics program available. It is a full featured 3D modeling, animation and games development tool used by millions all over the world ñ and it's free! This book is for those looking for an entry into the world of 3D modeling and animation regardless of prior experience. Blender 3D Basics is the entry level book for those without prior experience using 3D tools. It caters for those who may have downloaded Blender in the past but were frustrated by its lack of intuitiveness. Using simple steps it builds, chapter by chapter, into a full foundation in 3D modeling and animation. Using Blender 3D Basics the reader will model a maritime scene complete with boats and water, then add materials, lighting and animation. The book demystifies the Blender interface and explains what each tool does so that you will be left with a thorough understanding of 3D.

Time for action — seeing what fields look like

I made a Blender file that has the white square on the black background for you. Looking at it in action may help you get an idea of what goes on with fields:

Load the program 6907_12_Fields.blend from your Chapter 12 download pack.
Press F12. You see a white square on a black background.
In the Post Processing subpanel of the Render panel in the Properties window, check the Fields checkbox.
Press F12.

What just happened?

When you have fields turned on, two images are rendered and merged. One image represents the time during the first half of the frame. Every other line is rendered. The other represents the time during the second half of the frame. Then the alternating lines are rendered.

When both fields are rendered, on the computer screen, the image looks like the following screenshot. The left-hand fringe is where the square was only during the first field, the right hand fringe is where the square was only during the second field. The solid...
