====== Attribute Editor ======

The Attribute Editor enable to modify the [[:01_user_documentation:06_graph:02_node:01_attribute|attributes]] of an object. When an object is selected, if the attribute editor panel is opened, it will automatically display its attributes. The attribute editor panel allows users to edit a wide range of attributes associated with different types of objects.

=====  =====

The attribute editor display:
  * User-defined configuration settings
  * Geometric properties of scene elements
  * Resource attributes such as 3D materials

Each attribute has a defined type, which determines the corresponding editing component. For example:

  * A numeric attribute (e.g., the radius of a sphere) is edited via a simple input field.
  * A 3D vector (e.g., the orientation of a cylinder) is edited through three numeric fields.
  * Complex attributes (e.g., 3D materials) consist of multiple sub-attributes, each with its own edit interface.

Many attributes in GroIMP support multiple value types. In such cases, a type-selection button is provided. Once a type is selected, the editor dynamically generates suitable input components inside a collapsible sub-panel. These panels can be minimized or expanded using the small button on their upper border, or by double-clicking, which expands one and collapses all others.

===== Example: Attributes of a Phong Material =====


{{:user-manual:imgmatattr.png}}

In the case of a Phong material (as depicted in the Figure below), attributes include:

  * Channel Input
  * Diffuse Colour
  * Transparency
  * Interpolated Transparency
  * Ambient Colour
  * Emissive Colour
  * Specular Colour
  * Shininess

The example uses a Checkerboard 2D map for the Diffuse Colour, which in turn has attributes such as its own Channel Input, Colour 1 and Colour 2. Each of these can be further customized—for instance:

  * Colour 1 is an RGB color modified via sliders.
  * Colour 2 is set to an image map, though other types (e.g., constant color, RGB, or another checkerboard) are also valid options.
