Detailed Description

template<class T, class M = Math<T>>
struct a3d::Matrix3< T, M >

A matrix of nine values for 3d calculations.

Observe that the data is stored in column-major mode for easy interfacing with OpenGL. The interfaces are specified in row-major mode (for example the constructor and print operator).

		S	a
	)

inlinestatic

Creates a matrix representing a rotation around the specified axis.

The vector represented by (x,y,z) MUST be of unit length or the result will be wrong!

References a3d::Matrix3< T, M >::m, and a3d::Vector3< T, M >::v.

template<class T, class M = Math<T>>

template<class T2 , class M2 >

static Matrix3<T,M> a3d::Matrix3< T, M >::fromScale ( const Vector3< T2, M2 > & s )

inlinestatic

Creates a scaling matrix.

template<class T, class M = Math<T>>

Matrix3<T,M> a3d::Matrix3< T, M >::inverse ( ) const

inline

Returns the inverse of the matrix.

This function is not optimized and is therefore extremely inefficient.

References A3D_WARNING_EXPENSIVE, a3d::Matrix3< T, M >::comatrix(), and a3d::Matrix3< T, M >::determinant().

Here is the call graph for this function:

template<class T, class M = Math<T>>

void a3d::Matrix3< T, M >::loadIdentity ( )

inline

Make this matrix identity, i.e.

ones in diagonal.

References a3d::Matrix3< T, M >::m.

Referenced by a3d::Matrix3< T, M >::Matrix3().

template<class T, class M = Math<T>>

a3d::Matrix3< T, M >::operator const T * ( ) const

inline

Casts this matrix to an array representation.

This makes it possible to provide for example a float matrix as an array argument in for example OpenGL.

Use like this:

Matrix3f m;
glGetParamv( GL_MODELVIEW_MATRIX, (float*)m );

References a3d::Matrix3< T, M >::m.

template<class T, class M = Math<T>>

a3d::Matrix3< T, M >::operator T * ( )

inline

Casts this matrix to an array representation.

This makes it possible to provide for example a float matrix as an array argument in for example OpenGL. Anything written in the returned array will end up in the matrix.
