Display menu
IMPORTANT When About rollout > Choose Solver is set to Havok 3, only Camera
Settings is available from this menu.
Camera Settings Opens a dialog that allows you to specify the near and far
clipping planes for the camera, and to change the camera’s field of view
(F.O.V.). The clipping planes can also be set externally from the reactor utility
Display rollout.
Faces When on, the faces (and not the edges) of the display bodies are
rendered.
Wireframe When on, the edges (and not the faces) of the display bodies are
rendered.
Sim Edges When on, the edges of the physically simulated geometry (the
simulation geometry for each body) are rendered in the preview window. This
is useful for seeing what’s physically happening in a simulation.
Grid When on, three 2D grids are displayed in the XY, YZ and ZX planes.
Origin When on, the X (in red), Y (in green) and Z (in blue) axis are displayed
at the origin (0,0,0).
Flashlight On/Off When on, a flashlight located behind the camera lights
the scene. When off, lights defined on the Display rollout of the utility are
used. If no lights are defined, the preview uses a single fixed light.
Performance menu
Fixed Step (60,50,40,30 fps) Choosing one of these options changes the
frequency of the simulation to the given value; a frequency of 30 fps yields a
time step of 1/30 (0.0666) second, 50 fps means a time step of 1/50 (0.02)
second, etc.
Substeps (1-100 substeps) Choosing of these options sets the number of
substeps taken in every simulation step.
Mouse menu
This menu is available only when using the Havok 1 engine.
Pick at C.O.M. During the preview, you can pick and drag objects (see
To
interact with objects in the Preview Window :
on page 4099. A spring is the
attached between the mouse cursor in the screen and the object. When this
option is on, the spring is attached to the center of mass of the object.
