Direct Color - Fractal Science Kit Example
|
|
|
The Direct Color example uses a direct color controller to color the fractal. The base fractal data and the data defined by Alternate Mapping 1 and Alternate Mapping 2 are combined to generate each pixel's RGB value.
Experiment 1
Use the Preview Julia command to explore the Julia fractals for this example.
Experiment 2
Try out different Fractal Equations. To do this, select the Fractal Equation: Mandelbrot properties page:
General
Mandelbrot / Julia /
Newton
Fractal Equation: Mandelbrot
Change the Based On property to any of the different Fractal Equations.
For each equation you try, make sure to select the equation's Properties page (if found) and play with the different settings.
Experiment 3
Change the Shape Transformation used to define Alternate Mapping 1. To do this, select the Shape Transformation properties page:
General
Mandelbrot / Julia /
Newton
Alternate Mapping 1: Minimum Value
Shape Transformation
Change the properties on this page to try out different shapes. See Shape Transformation for details.
Experiment 4
Change the Shape Transformation used to define Alternate Mapping 2. To do this, select the Shape Transformation properties page:
General
Mandelbrot / Julia /
Newton
Alternate Mapping 2: Minimum Value
Shape Transformation
Change the properties on this page to try out different shapes. See Shape Transformation for details.
Experiment 5
Change the transformation applied to the base fractal. To do this, select the transformation's Properties page:
General
Mandelbrot / Julia / Newton
Transformation
Composite
Function
Properties
Set the F(z) property to one of the complex functions in the list. You can change some of the other properties on this page for more variations.
Experiment 6
Change how coloring is applied to the resulting image. To do this, select the color controller's Properties page:
General
Mandelbrot / Julia /
Newton
Classic
Controllers
Direct Color Map - RGB Blend
Properties
Change any of the properties on this page to affect how the data is mapped to the color's RGB values.
These changes can be applied to the Mandelbrot or to any of the Julia fractals you create by clicking on the image in the Preview Window. A common approach is to execute the Preview Julia command and then click on the Mandelbrot until you get a Julia you like displayed in the preview window, then click on the Preview Window to open a full-sized version of the preview, open the Properties Window for the Julia, and then use the above techniques to adjust the Julia fractal's coloring.
