Detailed Description

General purpose float quad.

Uses include representation of color coordinates. No support yet added for float * Vec4ub - is it necessary? Need to define a non-member non-friend operator* etc. Vec4ub * float is okay

Member Typedef Documentation

typedef unsigned char osg::Vec4ub::value_type
