SoShuttle.3coin2

NAME

SoShuttle -

The SoShuttle class is used to oscillate between two translations.

A smooth transition between translation0 and translation1 is created using a cosine function. In the beginning of the cycle, translation0 is used. Halfway through the cycle, the resulting translation equals translation1, and at the end of the cycle, we're at translation0 again.

SYNOPSIS

#include <Inventor/nodes/SoShuttle.h>

Inherits SoTranslation.
