The Basics

The tutorial will begin with a look at the various trap modes using a single distance variant. When starting to work with any coloring formula I recommend that you uncheck the "repeat gradient" box on the outside tab in UltraFractal and use a simple gray-scale gradient such as "grayscale" in standard.ugr. This will enable you to see the basic shapes without being distracted by the colors. Coloring and textures will be dealt with later. The first set of images were created this way using the Cycloid trap type and a distance type of Abs parts. The upr shows the basic settings.  They vary primarily in the Trap mode used. The  trap modes which have automatic masking, use a dark red background to show the masked region. Examine each image carefully to see what differences the trap mode makes. The captions for each image provide hints, if necessary, for changes to the basic upr. The use should try to make the appropriate changes to duplicate the image.

Closest First
Trap width = 0.5
Last
Trap width = 0.5		 Smallest with mask
Trap width = 0.1
gradient rotated
Average with repeat gradient
Trap width = 0.5		 Farthest
gradient rotated
Sum with repeat gradient
Trap width = 0.5
color density = 2

The next set of images will explore a selection of coloring modes using the Closest trap mode with a trapping mask and a distance type of Abs total. The upr for Magnitude provides the basics. Hints for any changes are in the captions.
