Euler angles. Unlike a Rotation, Euler angles can represent multiple revolutions (rotations) around an axis, but suffer from issues like gimbal lock and lack of a defined "up" vector. Use Rotation for most cases.

An Axis Aligned Bounding Box.

A capsule object, defined by 2 points and a radius. A capsule is a cylinder with round ends (inset half spheres on each end).

Represents a color using 4 floats (rgba), with 0-1 range.

Represents a line in 3D space.

Represents a 4x4 matrix.

A struct describing an origin and direction

Represents a Quaternion rotation. Can be interpreted as a direction unit vector (x,y,z) + rotation around the direction vector (w) which represents the up direction. Unlike Angles, this cannot store multiple revolutions around an axis.

A struct containing a position, rotation and scale. This is commonly used in engine to describe entity position, bone position and scene object position.

A 2-dimensional vector. Typically represents a position, size, or direction in 2D space.

A 3-dimentional vector. Typically represents a position, size, or direction in 3D space.

A 4-dimensional vector/point.

Describes a curve, which can have multiple key frames.

Represents a frustum.

Describes a gradient between multiple colors

Represents a plane.

Represents a rectangle.

Represents a sphere.
