Viewport Navigation

The viewports are fully controllable with combinations of keys and mouse movements. RealFlow’s viewports support OpenGL, a fast method to display, draw and shade objects. The 3D modes (“Perspective View” and “SceneCamera View”) have three degrees of freedom for changing the point of view: Panning, zooming and rotating. The 2D views (“Top”, “Front”, “Side”) are restricted to panning and zooming.

1. Alt + LMB for rotating
2. Alt + RMB  for zooming
3. Alt + MMB for panning

The illustration below shows RealFlow's mouse control possibilities:

Updating the viewports is a very CPU intensive task and may take up to 30% of your processor’s capacity with slower graphic cards. Especially when you have large scenes with large particle amounts the simulation process might slow down tremendously. For these cases there are simple, yet effective methods to save CPU power:

• Use only one viewport while simulating, best is one of the 2D views.
• Minimize RealFlow’s entire workspace as much as possible.
• Click in an empty area of the viewport and then press Alt + D to deactivate the viewport. This is one of the most effective ways to accelerate your simulations!
• Use RealFlow’s Command Line version for the simulation process.
• Uncheck the “Display at frames” option under Preferences.

Perspective and Shading Modes

There are a few more shortcuts to alter perspective and display modes. These commands are also available from the "View" menu, and they are:
