Alternativa3D Changelog

5.5.0
-----

- Added mouse interaction. Objects of the classes Object3D, Surface and Face can now dispatch 3d mouse events
- Added property View.interactive 
- Added a new class Sprite3D
- Added new materials: SpriteTextureMaterial and DevMaterial
- Properties alpha and blendMode of the SurfaceMaterial class are moved to the base Material class
- Renamed following methods of the View class and changed their signature:
    getFacesUnderPoint -> getObjectsUnderPoint
    getFaceUnderPoint -> getObjectUnderPoint
- Added controlled clipping in Camera3D
- Added unload() method in classes Loader3DS and LoaderOBJ
- Loader3DS and LoaderOBJ can now load transparency maps
- Added method Scene3D.hasChanges()
- Added methods for coordinates transformation:
    Object3D.localToGlobal()
    Object3D.globalToLocal()
    View.projectPoint()
    View.get3DCoords()
- Method Object3D.getChildByName() can now perform recursive search in all child objects
- Added property Object3D.transformation, which returns global transformation matrix of an object

- Fixed bug in the method Scene.drawBSP(), which occured when there was a texture material without texture
- Fixed bug in texture rendering when UV-mapping is degenerated
- Fixed bug in the method Mesh.removeFace()
- Fixed bug in controllers, which occured when coordinates of a controller were being set without any object assigned
- Fixed bug in the methods View.getFaceUnderPoint and View.getFacesUnderPoint, which led to incorrect results when view had transformation
- Fixed bug in the LoaderOBJ class, which occured when the load() method was called twice
- Fixed bug in the method ObjectUtils.getClassName(), because of which names of the base Flash classes were incorrect

5.4.1
-----

- Fixed pivot point parsing bug in Loader3DS
- Fixed file parsing bug in LoaderOBJ
- Fixed bug, which caused unnecessary redrawing in some cases

5.4.0
-----

- Added View getFaceUnderPoint and getFacesUnderPoint methods,
  which let to get faces under set point
- Added WalkController and FlyController classes, which let
  to manage walk and fly modes
- Added EllipsoidCollider class, which implements ellipsoid-to-geometry
  collision detection
- Added Scene3D planeOffsetThreshold parameter - an offset for defining
  distances between point and splitter planes
- Added Set.createFromArray method, which creates set from array
- Added Matrix3D.axisAngleToMatrix method, which forms rotation matrix
  from axis-angle representation
- Added Matrix3D getRotations method, which gets rotation angles values
- Bug fixed in OBJLoader, which showed up during uploading model
  with textures but without UV-mapping
- Bug fixed in Mesh cloning, which showed up if surface has no material

5.3.0
-----

- OBJ-models loader added
- Mesh setMaterialToAllSurfaces method renamed to cloneMaterialToAllSurfaces
- Method close added to Loader3DS, manually interrupting uploading 
- Texture parameters made only for reading
- Bug fixed - there were no redrawing after faces UV-coordinates update
- Added indication of missing or incorrect UV-mapping doing texture drawing
- Optimized memory usage for collision detection
- Documentation updated

5.2.0
-----

- Renamed Mesh methods:
    addVertex -> createVertex
    addFace -> createFace
    addSurface -> createSurface
    addAllFacesToSurface -> moveAllFacesToSurface
- Face property num renamed to verticesCount
- Added an ability to exclude objects from collision detection
  in CameraController (collisionIgnoreSet)
- Added an ability to handle camera movement start and stop
  in CameraController (onStartMoving, onStopMoving)
- Optimized polygons sorting during BSP-building
- Optimized operation sorting (signals sistem)
- Added singular mapping check for faces
- Bugs fixed in 3DS files loader (TD-1063, TD-1073, TD-1074, TD-1083)
- Corrected geosphere mapping near poles
- Fixed bug in TextureMaterial cloning (precision didn't copy)
- Corrected some documentation errors

5.1.0
-----

- Library was adopted for Flash CS3 integration (added library support
  classes Alternativa3D, AlternativaTypes, AlternativaUtils)
- Alternativa3DVersion class removed; library version
  is in the support class now
- Added wire drawing in FillMaterial and TextureMaterial
- Fixed bugs in Cone (UV-mapping and bottom side)
- Improved CameraController (added acceleration action,
  changed default key bindings)
- Removed Alternativa3DLabel class; images are in the "labels" folder now
- Fixed typos
