Coding Style

• Modules: PascalCase
• Types/Classes: PascalCase
• Functions/Member: lowerCamelCase
• in place functions return void and have inPlace in their function name

History

1.1.1

• include jsdoc comments in bundled declaration output

1.1.0

• change Euler.fromQuaternion to Algorithm via Matrix (similar to ThreeJS) fixes Lutz Cushion bug ( ok @DC)

1.0.3

• 1.0.2 Quaternion.lookAt & Vector3.multiplyWithMatrix4Right
• Math: working lookAt with quaternions

1.0.2

• default Package.json Type is "Interactor" now
• new Quaternion lookAt function
• new version of Vector3.multiplyWithMatrix4() for updated matrix4 transformation called multiplyWithMatrix4Right()

1.0.1

• clamp asin input to -1 ... +1 for quaternion -> Euler transformation
• add more tests for questionable or plain wrong behaviour
• readd matrix fixes including new tests, no change of traditional behaviour
• unify rotation matrix creation

1.0.0

• fixed lookAt function
• change lookAt function for use with other base
• updated comments and tests
• Matrix4.lookAt() fix for negative z-values & license
• Matrix4 lookAt function
• added version logging and minification

1.0.0-alpha.0

• initial release
