A vector of spherical harmonic coefficients.

The integral of the constant SH basis.

Default constructor.

Scalar multiplication operator.

Changed to float& from float to avoid LHS

Scalar division operator.

Addition operator.

Subtraction operator.

Dot product operator.

In-place addition operator.

Changed from (*this = *this + B;} to calculate here to avoid LHS

Now this avoids TSHVector + operator thus LHS on *this as well as Result and more

In-place subtraction operator.

Changed from (*this = *this - B;} to calculate here to avoid LHS

Now this avoids TSHVector - operator thus LHS on *this as well as Result and

In-place scalar division operator.

Changed to float& from float to avoid LHS

Changed from (*this = *this * (1.0f/B);) to calculate here to avoid LHS

Now this avoids TSHVector * operator thus LHS on *this as well as Result and LHS

In-place scalar multiplication operator.

Changed to float& from float to avoid LHS

Changed from (*this = *this * B;) to calculate here to avoid LHS

Now this avoids TSHVector * operator thus LHS on *this as well as Result and LHS

Calculates the integral of the function over the surface of the sphere.

Scales the function uniformly so its integral equals one.

Compute the direction which the spherical harmonic is highest at.

Returns the value of the SH basis L,M at the point on the sphere defined by the unit vector Vector.

The ambient incident lighting function.
