Quick-Spin buttons

To the right of various columns and fields are the Quick-Spin buttons:

These open the Quick-Spin windows allowing you to quickly see how that parameter affects the fractal image. See: How to use the Quick-Spin panels

Column Definitions

Solo
When set hides the all transforms but this one are hidden in the fractal image. (Not a permanent setting - use Opacity instead.)
Weight (Quick-Spin capable)
The relative weight for this transform.
Color Index (Quick-Spin capable)
Index into Color Gradient color values for this transform.
Color Speed (Quick-Spin capable)
How rapidly the effective color index changes between iterations.
Opacity (Quick-Spin capable)
Alpha value for this transform.
Direct Color (Quick-Spin capable)
Amount of direct coloring to apply. Range is 0 to 1.
Only works with variation types that provide direct coloring support.
Rotates
Indicates whether this transform can be animated.

Transform List Buttons

+
Add new linear transform with identity pre and post **matrices.
-
Delete the selected transform.
Duplicate
Adds a new transform that is an identical copy of the selected transform.
Split
New ! Splits a transform into two identical transforms except for their weights which will be half of the original transform’s weight.
+ Random
Adds a new randomized transform with random variations and matrices.
+ Linked
Adds a new linked linear transform that is linked to the currently selected transform by chaos. (The chaos weight from the selected transform to the new transform is 100% and 0% to all others.)
+ Back Linked
Adds a new linked linear transform that is back linked to the currently selected transform by chaos. (The chaos weight to the selected transform from the new transform is 100% and 0% to all others.)
Chaos Weights
Adjust the chaos weights for the selected transform.More

Final Transform Tab

Final Transform panel
Final Transform panel

A final transform is applied to the point pool immediately after the ordinary transforms are applied. Most fractals do not use a final transform. They must be explicitly enabled.

Field Definitions

Enabled
When set hides the all transforms but this one are hidden in the fractal image. (Not a permanent setting - use Opacity instead.)
Color Index (Quick-Spin capable)
Index into Color Gradient color values for this transform.
Color Speed (Quick-Spin capable)
How rapidly the effective color index changes between iterations.
Opacity (Quick-Spin capable)
Alpha value for this transform.

Flame Parameters Tab

Flame Parameters panel
Flame Parameters panel

Field Definitions

Symmetry
Fractal symmetry. Integer value >1 implies image rotaional symmetry of same amount. Negative values are dihedral symmetry.
Desired Quality
Number of iterations per pixel.
Hue (Quick-Spin capable)
Color Hue offset from the color gradient definition (in degrees)
Super Sample Width
Flam4 anti-aliasing width in pixels (can be fractional).
Background Color
The background color for the fractal image.
Brightness (Quick-Spin capable)
Image brightness
Gamma (Quick-Spin capable)
Gamma value for flame fractal tone mapping
Vibrancy (Quick-Spin capable)
Color vibrancy.
Gamma Threshold (Quick-Spin capable)
Gamma linearization threshold.
Background Opacity
Opacity of fractal image (inverse of transparency).
Name
Name for this fractal.
Filter
Flam3 kernel size multipler for supersampled image reduction.
Supersample
Flam3 Supersample multipler. The fractal’s effective render size is supersample X image size. Used in conjunction with the filter setting to help control anti-alias high density areas of the fractal. Values greater than 1 greatly increase render times.
Highlight Clipping
Turns Highlight clipping on or off. Simplified Flam3 Highlight power setting. Clipping manifests itself as color shifts in high density areas. Clipped colors tend toward cyan, magenta, yellow, or white. See Highlight Power explanation for more info.

Field Definitions

Width
Fractal image width in pixels - the value to be stored in the file.
Height
Fractal image height in pixels - the value to be stored in the file.
X (Quick-Spin capable)
View camera center: x
Y (Quick-Spin capable)
View camera center: y
Scale (Quick-Spin capable)
View camera scale factor.
Zoom (Quick-Spin capable)
Scale the fractal by this power of 2. Also adjusts quality to compensate for zoom amount.
Pitch (Quick-Spin capable)
Adjusts the camera pitch (range 0 to 180 degrees).
Yaw (Quick-Spin capable)
Adjusts the camera yaw (range 0 to 360 degrees).
Roll (Quick-Spin capable)
Adjusts the camera roll. (range 0 to 360 degrees) When pitch and yaw are equal to 0, roll has the same effect as 2d rotation.
DOF (Depth-of-Field) (Quick-Spin capable)
Adjusts the artificial depth-of-field. (range of 0.0 to 1.0)
(The fractal is sharp at the point of focus and becomes blurred the further its points are from the center of focus - see Camera Height)
Perspective (Quick-Spin capable)
Adjust for Perspective distortion (range of 0.0 to 1.0)
Perspective of 0 is no distortion. Perspective of 1 is maximum distortion.
Camera Height (Quick-Spin capable)
Adjust the distance from the camera to the point of focus. Used together with DOF.

Viewport Tab - 3D Camera Settings

See: 3D Fractals for detailed explanation of the many 3D camera settings.

New ! The 3D viewing camera has these parameters:

Pitch
Adjusts the camera pitch (range 0 to 180 degrees).
Yaw
Adjusts the camera yaw (range 0 to 360 degrees).
Roll
Adjusts the camera roll. (range 0 to 360 degrees) When pitch and yaw are equal to 0, roll has the same effect as 2d rotation.
DOF (Depth-of-Field)
Adjusts the artificial depth-of-field. (range of 0.0 to 1.0)
(The fractal is sharp at the point of focus and becomes blurred the further its points are from the center of focus - see Camera Height)
Perspective
Adjust for Perspective distortion (range of 0.0 to 1.0)
Perspective of 0 is equivalent to Orthographic projection. Perspective of 1 is equivalent to normal Perspective projection.
Camera Height
Adjust the distance from the camera to the point of focus. Used together with DOF.

Additional Free Camera Settings

New ! Fractal Architect extends the classical Apophysis 3D Hack camera to make it better support 3D animations.

Camera X, Y, Z Eyepoint Location
Adjusts the camera’s eyepoint in the fractal world coordinates.
Camera FOV (Field-of-View)
Adjusts the camera’s Field of View of the camera frustum.
Camera Clip
Clip clips out points behind the camera.
Don’t Clip does not clip points behind the camera. Apophysis 3D Hack mode
Camera Ortho / Perspective
sets camera viewing behavior to either full Orthographic projective or full Perspective projective.

Viewport Tab - 2D Camera Settings

The 2D camera settings are much simpler.

Supplemental Color Curves

New ! Fractal Architect 4 fractals can utilize supplemental color curves. These operate much like the color curve editors in popular photo editor apps where you can manipulate the separate RGB, Red, Green, and Blue color curves.

Click the mouse on top of the color curve to insert a new control point, then drag it to shape the curve.

If the mouse is clicked close to an existing control point, it will be selected so you can drag it with the mouse to shape the curve.

Apply To Background
If selected, applies the color curves to the fractal’s background color too.
Copy
Copy the color curves definition to the clipboard.
Paste
Paste the color curves definition from the clipboard.
