Detailed Description

template<int N, typename T>
class WRAP< N, T >

Helper class for LUT parameters.

Helper class templates for improved syntax when accessing tables. LUT::operator[] returns a WRAP object which can be further dereferenced with operator[]. When N coordinates have been specified, WRAP queries the LUT to get the interpolated value. WRAP defines (operator T) to act as a variable of type T to return this value. In practice, here's what it looks like:

LUT<3,float> table; ... float x = table[10.2][3.3][1.4];

Here table[10.2] returns a WRAP<3,float>. The next two dereferences build up the internal VEC<3, float>, finally calling table.getValue(). The righthand-side expression is still a WRAP<3, float> at this point, but is implicitly coerced to a float to assign the interpolated value to 'x'.
