Displays objects as bounding boxes when moving, rotating or scaling. Especially with large scenes and many objects, this is a good means to increase display speed. Even standard fluid particles are drawn as boxes, while grid fluids are still represented as particles.
View Grid
Turns the grid in the viewport(s) on or off. “On” is the default setting.
...
Camera Safe Frame
To make use of this option, a camera is required. After the camera view has been enabled you can see two frames around the viewport. The outer frame is in cyan and exactly matches the camera view, independent of the viewport’s aspect ratio. The inner frame is blue and shows the title-safe area of the current view.
...
Show Preview Caption
With this option it is possible to print some basic information about the current scene directly to the viewport. The data are written to in the top right-hand corner and represent your settings under

Show Screen Texture
You can fit a bitmap into a viewport as a background. If you have several viewports open, it is possible to turn the loaded picture on or off for each viewport separately. RealFlow does not store the loaded image and it has to be applied with each launch.
...
Choose a bitmap to load into the viewport as a background. Supported file formats are TGA, BMP, JPG, PNG and TIFF. Please keep in mind that screen textures cannot be saved with a project or a layout file. Each time you restart RealFlow, the background image has to be applied again.
Zoom All
With this function all scene elements fit into the viewport.
Zoom Selected
If you want to fit the currently selected node(s) into the viewport, click on this entry.
Center Selected
Centre the select object(s) in the current viewport.
...
The mode of operation of these entries is exactly the same as described above, but here all nodes of the scene will be affected.
Wireframe
...
Back Faces
With this function it is possible to show the inside of objects when their normals are inverted.
...
RealFlow also supports a textured view and draws an object’s texture based on its UV coordinates.
"Show" Submenu
This menu contains a list with all of RealFlow's node types and you can choose which elements you want to display or hide in the viewport simply by checking or unchecking the desired entries.
Grid
To hide or show the viewport grid, please choose this option.
RealFlow Nodes
By default all available node types are visible in the viewport. Uncheck an entry to hide a node type.
Selection Highlighting
When a node or scene element is selected it is highlighted and displayed with a bright green colour to separate it from the other nodes. In some cases, this highlight effect is not desired and can be confusing. A very good example where “Selection Highlighting” will be switched off is most probably (interactive) meshing: when a mesh is not highlighted you will have a much better view of its polygon structure. It will also be easier to evaluate its quality and recognize subtle changes during the meshing process.
"Point of View" Submenu
You can change the current viewport view to “Top View”, “Front view”, “Side View”, “Perspective View”, and "Camera View". If you want to use a camera (“look through it”), it is also possible to drag the camera node from the “Nodes” panel to the viewport. Then, the perspective will be changed to the camera's view.
