  • Added the ability to generate very large images. See Generating Large Images for details.

  • Improved the texture mapping by using bilinear interpolation of colors for points between pixels.
  • Enabled several toolbar buttons on the Fractal Window during fractal generation to allow display of the associated windows even while generating a fractal.
  • Fixed the Texture List Control to update the remembered texture folder when you repair a texture.
  • Fixed the built-in Orbital Equation Symmetric Icon - Non-Polynomial Term (Search) with respect to printing the information to the Error/Debug Window.
  • Fixed Example 6 of the built-in Orbital Equation Symmetric Icon - Non-Polynomial Term.
  • Fixed Angle Factor 3, 7, 11, and 15, for the optimized alternate mappings Average Value and Transformed Value Average.

Changes in Release 1.9 (01/16/2009)

  • Fixed Visible though translucent objects property on the General properties page with respect to Orbital fractals.
  • Fixed bug where cutting all items from list did not place items on clipboard.
  • Fixed bug where Data Information Window incorrectly enabled/disabled some of its controls.
  • Added logic to remember current folder when saving files.
  • Added Enabled option to the following transformations:
    - Kaleidoscope - Slices
    - Kaleidoscope - Squares
    - Kaleidoscope - Triangles
  • Added classic controller Pattern Map - Texture (Planar).
  • Added several options to classic controller Pattern Map - Perlin Noise (Planar).
  • Added orbit trap controller options Style and Shadow to the 3D mapping section. The new Edged style adds a bar-like appearance to any curved orbit trap. See Orbit Trap Controllers for details.
  • Added a Bend Pattern option to several pattern-based orbit trap controllers.
  • Added code to normalize the value returned by PerlinNoise functions. The functions now return a value strictly between -1 and 1. See Perlin Noise Functions for details.
  • Changed the default Factor from 0.125 to 0.25 in the Perlin Noise orbit trap controller.
  • Changed the default Factor from 0.125 to 0.25 in the Perlin Noise classic controllers.
  • Changed name of classic controller Pattern Map - Perlin Noise (Pixel) to Pattern Map - Perlin Noise (Planar).

Changes in Release 1.8 (11/26/2008)

  • Fixed error when trying to copy list items. Error would occur when you tried to copy list item after previously disposing of a list control. Lists include gradients, textures, and controllers.
  • Terminate Show Orbit if the orbit point falls far outside image. Before this change, application could hang if you used Show Orbit when zoomed way in.
  • Remove Orbits property from orbital fractal properties page. This was overly complex and unnecessary since you can use Max Count to increase the number of orbit points.
  • Replace Zinit Range with Initial Z in orbital equation. The need for Zinit Range was related to obsolete Orbits property.
  • Minor updates to simplify several built-in Orbital Equations.

Changes in Release 1.7 (10/30/2008)

  • Added the following Orbital Equations:
    - Koch Snowflake (Variations)
    - Symmetric Attractors
    - Symmetric Attractors (Search)
    - Frieze Group
    - Frieze Group (Search)
    - Hyperbolic Attractors
  • Added new data files Examples.sa and Examples.fz to support Orbital Equations Symmetric Attractors and Frieze Group.
  • Added support for injecting scaling transformations into the IFS to IFS (Search).
  • Added new data file Examples2.ifs with some examples using the new scaling options added to IFS (Search).
  • Added method Affine.InitializeWeights2 to built-in macros. This method is used to initialize the probabilities associated with an array of affine transformations for the purpose of generating an IFS fractal from the transformations.
  • Added method Affine.ScaleDimension to built-in macros. This method can be used to sharpen/blur an IFS fractal without changing its general shape.
  • Added an option to control the method used to generate weights in Orbital Equations:
    - IFS Examples - Chaos and Fractals
    - IFS Examples - Yale
    - IFS (Search)
  • Added an option to sharpen/blur the IFS in the Orbital Equation IFS File Processor.
  • Added logic to adjust the Orbital fractal's Max Count based on window size. This reduces the need to adjust Max Count manually when you change the size of the window and improves the performance of the Preview window with respect to Orbital fractals.
  • Added a color adjustment option to several strange attractors.
  • Added several examples to Orbital Equation Symmetric Icon - Variations.
  • Improved Orbital adaptive smoothing algorithm.
  • Improved performance of search algorithm used to find strange attractors.
  • Added Clear All menu item to context menu on editor pane.
  • Moved ZInit Min/Max from Orbital properties page to Orbital Equation properties page.
  • Changed several Orbital Equations to use a fixed initial z.
  • Changed Fractal Equation properties page to show both Julia Constant and Initial Z fields.
