Constructor & Destructor Documentation

template<typename T >

vmml::Frustum< T >::Frustum

Member Function Documentation

template<typename T >

void vmml::Frustum< T >::adjustNearPlane

(

const T

nearPlane

)

Move the frustum near plane.

Changes the position of the nearPlane, adjusting the other parameters in a way that the shape of the perspective pyramid stays the same.
