 The Camera menu of GroIMP's 3D view allows the selection of different cameras. Some cameras are predefined, among them the common orthographic projections. You can add user-defined cameras to your project in the Camera Explorer (the menu item Panels/Object Explorers/3D/Cameras brings it up); these cameras can be selected as current camera in the Camera menu, too. They can be edited through the navigation facilities or in the Attribute Editor.

 ===== Select objects =====
-You can select object by clicking on them. It is possible to hold ''CTRL'' and select multiple objects.
+You can select object in the 2d and 3d view by clicking on them.
+In the 3d view it is also possible to hold ''shift'' and drag the cursor with the left button pressed to draw a box, after releasing the mouse all object in the box are selected.
+It is possible to hold ''CTRL'' to combine multiple selections.

 ===== Change the default display =====
-The Render View menu displays the installed external renderers. The POV-Ray Plugin defines an interface to the external renderer POV-Ray, a free ray-tracer, which can be used to render 3D scenes in high quality, see [[POV:index | POV-Ray]] manual.
+GroIMP features OpenGL-accelerated display of the scene. The OpenGL-based display may be selected if the //Java Binding for the OpenGL API// (JOGL) is installed. The menu View/Display of GroIMP's 3D view brings up the selection for the different supported display modes. These are:
+  * **Wireframe (AWT)**: A wireframe view of the scene. Will run on all systems.
+  * **OpenGL**: OpenGL-based view. Will run on all systems with OpenGL 1.1 support. This mode will display colors and simple textures.
+  * **OpenGL (Proteus)**: OpenGL-based view. Requires a OpenGL 2.1 compatible GPU. This mode will preview the output of the internal raytracer Twilight in realtime. It features:
+    * Preview of most materials including procedurally calculated shaders using the OpenGL Shading Language (GLSL)
+    * Per pixel lighting
+    * Rendering of shadows
+    * Preview of Sky-Nodes as background
+    * Rendering of transparent materials

+Navigation and control is the same for the Wireframe and both OpenGL-based modes as explained in [[ :3d-guide:view_manipulations#navigate_in_the_scene|how to navigate in the scene]]. A comparison of all three modes for an example scene is shown in figure 2.

+===== Render the scene =====
+You can render the current scene with the ''Render View'' menu item.
+GroIMP embed two default renderer:
+  - Twilight, based on the main Ray tracer (see [[user-guide:raytracing#default_renderer| this page]] for more details)
+  - Fluxrenderer, based on GPUFlux (see [[user-guide:raytracing#flux_renderer| this page]] for more details)
+Additionally it is possible to add external renderer in GroIMP. Currently the only external renderer is:
+  - POV-Ray, a free ray-tracer, which can be used to render 3D scenes in high quality (see [[POV:index |here]] for more info)
