Extensions
These settings enable you to optimize OpenGL for CINEMA 4D. The best settings depend on your
system’s hardware and drivers. Try each option to nd out which settings work best.
Active Object Plane, Highlight Plane
These options speed up the movement of objects and refresh rate of the highlight plane (the yellow
highlighting that appears when the mouse pointer is over polygons in polygon mode). Only relevant
parts of the screen will be redrawn; complex background areas may not have to be redrawn.
Up to three internal planes are created depending on which of the two options are enabled:
 Both options disabled
Uses a single plane that should work with any graphics card.
 Active Object Plane enabled, Highlight Plane disabled
Two planes are created. The second plane is used exclusively to redraw the
highlighting.
 Both options enabled
Three planes are created. The active objects are drawn on the second plane;
the highlighting is drawn on the third plane. Depending on which view you are
working in, only the relevant plane must be updated, which naturally provides
a faster viewport refresh.
Use ARB Extension For Dual Planes
This option switches to an alternative method for displaying dual planes. Depending on the hardware,
this method may provide a faster viewport refresh. The option will be ghosted if it is not supported
by your graphics card’s driver.
OpenGL Hardware Lighting
If you enable this option, your graphics card will take over the task of lighting the objects in the scene.
This will usually give you a faster refresh rate in the viewport, depending on the performance of your
graphics card.
OpenGL hardware lighting supports the following features only:
 Environment object
- Environment Color
- Fog (3D view only)
 Light source objects
