Detailed Description

Mass data.

This holds the mass data computed for a shape.

Note

This data structure is 16-bytes large (on at least one 64-bit platform).

Constructor & Destructor Documentation

MassData() [1/2]

box2d::MassData::MassData ( )

default

MassData() [2/2]

constexpr box2d::MassData::MassData ( Mass  m, Length2D  c, RotInertia  i  )

inlinenoexcept

Initializing constructor.

Parameters

m	Non-negative mass in kg.
c	Position of the shape's centroid relative to the shape's origin.
i	Non-negative rotational inertia of the shape about the local origin.

Member Data Documentation

center

Length2D box2d::MassData::center

The position of the shape's centroid relative to the shape's origin.

I

RotInertia box2d::MassData::I

Rotational inertia, a.k.a. moment of inertia.

This is the rotational inertia of the shape about the local origin. This should NEVER be a negative value.

Note

Behavior is undefined if this value is negative.

mass

Mass box2d::MassData::mass

Mass of the shape in kilograms. This should NEVER be a negative value.

Note

Behavior is undefined if this value is negative.
