Slope Formula Tutorial for UltraFractal - Page 5

3D Texturizer Enhanced III

3D Texturizer Enhanced III  has two lighting options, and trap and texture capabilities. Only a selection of the parameters will be discussed. The main topic areas will be

• Gradients - Gradients structured like the Silver Lighting gradient shown on the Basic Usage page provide a good starting point for 3D-like images. More complex gradients can provide some striking effects, especially if used in conjunction with different Height Value selections.
• Application of texture - There are 3 different types of texture available.
  fBm textures - This includes options that couple with the Lattice textures. 
  Lattice textures - These textures are overlaid slope textures
   General textures - These textures provide a variety of shapes 
• Use of the trap capabilities - There are two types of traps.
• Trap by Height - Trapping is dependent upon the height values of the fractal. The trapped region can be the portion of the fractal with the lowest heights or the portion with the greatest heights.
• Trap by Iteration - Trapping is dependent upon the number of iterations.

The Texture1 uses a Salmon lighting gradient with a zoom into SlopeExp (Julia). With Texture2 a custom gradient is used along with a Height Value = Line. This creates a more striking effect. Progressing to Texture3 a Height Trap has been applied along with the addition of a small amount of fBm texture and Lattice texture. Texture4 is a three layer image with an additional layer that uses an Iteration Trap, fBm texture and General textures, and a background layer.

Texture3	Texture4

Texture4 can be generated by copying the upr below and pasting it into UltraFractal. The upr will generate an image that is 640 x 640 pixels. Study the parameter settings in the top two layers for 3D Texturizer Enhanced III to see how the ucl is used.

Another 3 layer example is shown in Texture5. This image uses SlopeExp (Fun_BarnselyJ1) for all three layers with Height Value = smallest |real(z)|. The top layer uses Trap by Height, the middle layer uses Trap by Iteration, and the bottom layer uses no traps but uses all three textures.
