-===== Chapter 1. GroIMP's 3D Plugin =====
-** 1.1. Overview **
-As GroIMP's primary purpose is the modelling of three-dimensional virtual plants, GroIMP's 3D facilities play a prominent role. They are made available by the 3D plugin and contain the following features:
-  * 3D geometry objects: Spheres, cones and other primitives, curves and various kinds of NURBS surfaces, heightfields.
-  * Materials can be assigned to objects to produce a variety of shading effects in visualization. Materials are defined using a _shading network_: This establishes a data flow through the nodes of the network which finally leads to the visible material properties like colour and opacity. Several kinds of nodes are available: Image maps, procedural maps, transformations. You can freely mix them in the shading network, which gives you great flexibility in defining materials.
-  * An integrated viewer displays the current scene in three dimensions. Easy navigation is enabled by navigation buttons; objects can be selected in the viewer. Currently, the viewer supports a simple wireframe representation on all Systems. An OpenGL-based representation is available for Systems where the _Java Binding for the OpenGL API_ (JOGL) is installed.
-  * External renders can be used to create a 3D view of higher quality. The POV-Ray Plugin provides a scene export to the POV-Ray format which makes it possible to use the free ray-tracer POV-Ray as an external renderer, see the [[POV:index | POV-Ray manual]]. The resulting image is directly shown in GroIMP's 3D view.
