Migration

##r52 → r53dev

• ...

##r51 → r52

• ShaderExtras have been split in a different files. CopyShader, FXAAShader, NormalShader, etc
• Replaced SceneUtils.traverseHierarchy with object.traverse.
• Removed SceneUtils.showHierarchy. Use object.traverse( function ( child ) { child.visible = false } ) instead.
• Moved *Controls to examples/js/controls.

##r50 → r51

• CameraHelper API changes: helper is not anymore child of camera, instead it uses reference to camera world matrix
• texture uniform changes: texture units are now assigned automatically, texture object goes to value property instead of texture one { type: "t", value: 0, texture: map } => { type: "t", value: map }
• normalScale uniform in normal map shader is now Vector2 (to be able to invert separately x and y to deal with different tangent bases)
• CTMLoader.load and CTMLoader.loadParts now use single parameter object for useWorker and useBuffers: loader.load( url, callback, useWorker, useBuffers ) => loader.load( url, callback, { useWorker: true, useBuffers: true } )
• CTMLoader now creates BufferGeometry by default, set useBuffers parameter to false if you need Geometry
• type for non-procedural geometries changed in the scene format: ascii_mesh => ascii, bin_mesh => binary, embedded_mesh => embedded
• UTF8Loader (and compressor) were changed to a newer version, supporting more recent version of UTF8 format (r100+); loader doesn't create anymore geometries but instead it returns hierarchy with potentially multiple meshes created per each material (or by splitting large model)

##r49 → r50

• Vector3's .getRotationFromMatrix( matrix, scale ) to Vector3's .setEulerFromRotationMatrix( matrix, order ).
• Vector3's .getEulerXYZFromQuaternion( quaternion ) and .getEulerYZXFromQuaternion( quaternion ) to .setEulerFromQuaternion( quaternion, order ).
• DOMRenderer and SVGRenderer no longer included in common build.
• texture coordinates aren't anymore flipped in the geometries, instead textures have flipY property (true by default); all models need to be re-exported / reconverted (tools have been updated as well).
  workaround: uv.v = 1 - uv.v;
• PlaneGeometry changed back to vertical orientation (facing screen instead of laying on the ground).
  workaround: mesh.rotation.x = - Math.PI / 2; or geometry.applyMatrix( new THREE.Matrix4().makeRotationX( - Math.PI / 2 ) );
• doubleSided / flipSided properties moved from Object3D to Material's side property (THREE.FrontSide, THREE.BackSide and THREE.DoubleSide).
• objectMatrix in shaders was renamed to modelMatrix.
• JIT caching removed from Animation.
• geometry.dynamic is now true by default.
• Three.js build renamed to three.min.js.

##r48 → r49

• changed PlaneGeometry from vertical to horizontal orientation.
• renamed __dirtyXXX attribute properties to xxxNeedUpdate.
• removed Vertex class, use Vector3 instead.

##r47 → r48

• Removed intersectScene from Ray. Use intersectObjects( array ) instead.

##r45 → r46

• loader.load( { model: url, callback: callback } ) to loader.load( url, callback ).
