Basic Nodes are the indivisible building blocks (like atoms) from which textures are made. They perform a wide variety of simple and straightforward image manipulation tasks, such as generating a gradient or blurring an image. Yet despite their apparent simplicity, just about any material can be simulated by stringing together the right combination of Basic Nodes.
Basic Nodes will be most useful to experienced Genetica users. New users should check out the Advanced Nodes.
Basic Nodes fall into several categories, as shown in the following table.
Category

Description
|
3D
|
3D nodes use a height map to create various three-dimensional effects.
|
Color
|
Nodes that influence the color of their input.
|
Combine
|
These nodes combine multiple inputs into a single image.
|
Effect Map
|
These nodes don't affect the texture itself, but rather allow you to create and manipulate additional channels that can be used by 3D applications (as bump or specular maps, for example).
|
Environment
|
Nodes that create and manipulate environment maps (HDRI spherical panoramas).
|
Filter
|
Nodes in this category take a single input which they alter in some way.
|
Generate
|
These nodes create basic patterns from scratch, and therefore often serve as the starting points of your textures.
|
Group
|
These nodes allow you to organize the nodes comprising your textures into units that are easy to understand, edit, and reuse.
|
Transform
|
Nodes that remap the pixels of their input to new positions.
