Namespaces

You can use the following modules:

| Namespace | Description | | ---------------------- | :-------------------------------------------------------------------------------- | | IG.Math | Global space functions like Rad/Deg and Polar/Cartesian conversion, ... | | IG.Math.Bounds | Bounding Boxes | | IG.Math.Euler | Calculations with euler angles | | IG.Math.Line | A line, consisting of an origin and a direction | | IG.Math.LinearAlgebra | Various convenience functions | | IG.Math.MathS | Safe Math functions to avoid getting NaN | | IG.Math.Matrix3 | 3x3 Matrix functions | | IG.Math.Matrix4 | 4x4 Matrix functions | | IG.Math.Plane | A plane, described by its normal and a point that lies in it | | IG.Math.Quaternion | special Vector4 describing a rotation | | IG.Math.Ray | A ray, consisting of an origin and a direction | | IG.Math.Transformation | The transformation of an object consists of a position and 3 rotations in radians | | IG.Math.Vector2 | {x, y} Vector functions | | IG.Math.Vector3 | {x, y, z} Vector functions | | IG.Math.Vector4 | {x, y, z, w} Vector functions |

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
