Detailed Description

two dimensional Cartesian vector object

This object represents a two-dimensional location or vector in Cartesian space, consisting of the x and y axes. Many operators and utility functions corresponding to operations on the 2D plane are defined.

Member Function Documentation

lerp() [1/2]

vec2 & vec2::lerp ( const vec2 & a, const vec2 & b, float t )

inline

Linearly interpolates between two other vec2s according to scale t.

If 0 < t < 1 then the matrix will be t% of the way between this and to. Values outside 0..1 imply a linear extrapolation.

Parameters

a	the first vec2 to interpolate from
b	the other vec2 to interpolate between
t	the interpolation factor

lerp() [2/2]

vec2 & vec2::lerp ( const vec2 & b, float t )

inline

Linearly interpolates between another vec2 according to scale t.

If 0 < t < 1 then the matrix will be t% of the way between this and to. Values outside 0..1 imply a linear extrapolation.

Parameters

b	the other vec2 to interpolate between
t	the interpolation factor
