class  MapBase
 Abstract base class for maps. More...
 
class  MapRegistry
 Threadsafe singleton object for accessing the map type-name dictionary. Associates a map type-name with a factory function. More...
 
class  AffineMap
 A general linear transform using homogeneous coordinates to perform rotation, scaling, shear and translation. More...
 
class  ScaleMap
 A specialized Affine transform that scales along the principal axis the scaling need not be uniform in the three-directions. More...
 
class  UniformScaleMap
 A specialized Affine transform that scales along the principal axis the scaling is uniform in the three-directions. More...
 
class  TranslationMap
 A specialized linear transform that performs a translation. More...
 
class  ScaleTranslateMap
 A specialized Affine transform that scales along the principal axis the scaling need not be uniform in the three-directions, and then translates the result. More...
 
class  UniformScaleTranslateMap
 A specialized Affine transform that uniformaly scales along the principal axis and then translates the result. More...
 
class  UnitaryMap
 A specialized linear transform that performs a unitary maping i.e. rotation and or reflection. More...
 
class  NonlinearFrustumMap
 This map is composed of three steps. First it will take a box of size (Lx X Ly X Lz) defined by a member data bounding box and map it into a frustum with near plane (1 X Ly/Lx) and prescribed depth Then this frustum is transformed by an internal second map: most often a uniform scale, but other effects can be achieved by accumulating translation, shear and rotation: these are all applied to the second map.

class  CompoundMap< FirstMapType, SecondMapType >
 Creates the composition of two maps, each of which could be a composition. In the case that each component of the composition classified as linear an acceleration AffineMap is stored. More...
