button. If you don’t assign a camera, the settings on the current Perspective
viewport (if any) are used initially in the Preview Window.
Camera Clipping Planes If a camera is assigned, the display tries to use the
camera to generate clipping planes. If no camera is assigned, reactor uses
default values for the clipping planes in the display.
Use Defaults It is possible that the clipping planes for your specified camera
are not sufficient to display everything in the scene. Rather than having to
change these values in the window every time the simulation is run, you can
turn off Use Defaults and then specify your own clipping planes using the
Near Plane and Far Plane values.
■ Near Plane The near plane to be used when Use Defaults is off.
■ Far Plane The far plane to be used when Use Defaults is off.
Lights Lists the scene lights reactor uses for the preview. When the list is
empty, reactor creates and uses a flashlight at the camera position; you can
toggle this light from the Preview Window > Display menu. You can combine
up to six omni lights or spotlights to create the preview lighting. Choose lights
from the scene one at a time with the Pick button, or add from a list of the
available lights in the scene using the Add button. To remove a light from
this list, highlight it in the list and then click Delete.
Texture Quality The size (NxN pixels) of the textures generated for use in the
display. A smaller value uses less memory.
Mouse Spring These options allow you to configure the spring used when
you select objects with the right mouse button (Havok 1) or Spacebar (Havok
3) in the
preview window on page 4099.
■ Stiffness The stiffness of the mouse spring. If the mouse spring is too
strong you might be able to pull objects through each other; this won’t
cause errors, but it can create an undesirable state. Default=30.0.
■ Rest Length The rest length of the mouse spring. Default=0.0.
■ Damping The damping value for the mouse spring. Default=1.0.
Use DirectX When on, the 3D rendering in the preview window uses the
DirectX system. When off, the window uses OpenGL.
