Nodes Tab

Top  Previous  Next



The Nodes tab reveals Genetica's primary workspace where textures and filters are edited.  At least one texture must be open for this tab to be available.  Please refer to the tutorials for an introduction to using this area.







1. Button Bar


Running along the top of the Nodes tab workspace are a number of buttons.  From left to right:






Removes the currently selected node and all of its child nodes and places them on Genetica's clipboard for possible pasting into a new location.


Copies the currently selected node and all of its child nodes to Genetica's clipboard for possible pasting into an additional location.


Pastes the node branch currently residing in Genetica's clipboard to the selected location.  Anything already at that location will be overwritten during this operation.

Paste Below

Pastes the node residing in Genetica's clipboard below the selected location.  This operation will not remove or replace any nodes.

Paste, Keep Inputs

Replaces the node at the selected location with the one in Genetica's clipboard while maintaining any nodes in its input slots.

Delete Current

Removes the selected node while preserving the child nodes that appear above it.  If the node has more than one input, only the first of the node's non-empty inputs will be preserved.

Group Branch

Helps you organize your texture by placing the selected node and all of its inputs within a Group node.

Randomize Branch

Randomizes some of the properties of the selected node and its inputs.

Create Floating View

Opens a window that contains a large preview of the currently selected node.  For more details, please see Floating Views.




2. View Controls


View-related controls appear in the right half of the button bar.





Zoom slider

Zooms the workspace in order to bring different numbers of nodes into view.  Alternatively, position your mouse over the workspace and use the mouse wheel.


Zooms the view out in order to bring as many nodes into view as possible.  Also centers the view in case the view had been panned away from the action.


Brings up a small map showing all workspace nodes at once.  Clicking or dragging the map will quickly pan the view to the desired location.  The view can also be panned by right-dragging any part of the workspace, or by using the scrollbars that may appear along the sides of the workspace.


If the view is within a Group node, then the Out button can be used to move the view out of the group.



3. Group Inputs Bar


The bar running along the top of the workspace shows the inputs being fed into the group at the previous level. To insert a reference to one of the group's inputs, drag the corresponding image from the Group Inputs bar to the desired position within the workspace.




4. Group Breadcrumbs


Lists the nested groups leading to the current position within the texture, mirroring the thumbnails found within the Nested Groups tab (10).  For example, the status bar could read 'View: Box Texture.gtx > Group "Tape",' which is the same as saying, "The view is currently showing us the contents of a Group named "Tape," which itself is within a texture named "Box Texture.gtx."  Clicking on any of the entries within the breadcrumbs will move the view to that level.




5. Properties Panel


Most Image Nodes have a number of properties that affect how they operate.  The Properties panel lists these properties so that they can be edited.  (Unlike Image Node properties, Lab Node properties are mainly found in the Lab tab.)


Up Down Modifiers

If clicking the up/down arrows next to numeric properties changes the value too quickly, hold down Ctrl while clicking for increments that are 10% of normal, and hold down Shift for increments that are 1% of normal.


You can also type in simple path operations.  For example, "2*4" will be interpreted as "2 times 4", and a value of 8 will be entered as soon as the Enter key is pressed.  Supported operations are:



The first number is added to the second number.


The first number has the second number subtracted from it.


The first number is multiplied by the second number.


The first number is divided by the second number.


The first number is raised to the power of the second number.




6. Library Panel


Provides easy access to nodes, previously made textures, and texture components so that they may be incorporated into current projects.
