A class representing a color, coded as you might expect, as a vector of three
float values. It doesn't have a (float) constructor but this code does
compile with gcc 3.2. I'm not sure how it could, but my C++ is a bit rusty.
The constructors are:
/// Default constructor.
CqColor() : m_fRed( 0.0f ), m_fGreen( 0.0f ), m_fBlue( 0.0f )
{}
/** Component constructor
* \param fRed red component 0.0-1.0
* \param fGreen green component 0.0-1.0
* \param fBlue blue component 0.0-1.0
*/
CqColor( TqFloat fRed, TqFloat fGreen, TqFloat fBlue ) :
m_fRed( fRed ),
m_fGreen( fGreen ),
m_fBlue( fBlue )
{}
/** 3D vector constructor.
* \param From the vector to copy the component values from.
*/
CqColor( const CqVector3D& From )
{
*this = From;
}
/** Array component constructor.
* \param From array of floats to use as the components.
*/
CqColor( const TqFloat From[ 3 ] ) :
m_fRed( From[ 0 ] ),
m_fGreen( From[ 1 ] ),
m_fBlue( From[ 2 ] )
