Vec2

2 dimensional floating point vector

Declaration

vec2 aVec2 = vec2(1.0, 1.0);
vec2 bVec2 = vec2(1.0);

vec2 cVec2 = vec2(aVec3);
vec2 dVec2 = vec2(aVec3.x, aVec3.y);

Description

vec2 is a floating point vector with two components. It can be initialized by:

• Providing a scalar value for each component.
• Providing one scalar value. This value is used for all components.
• Providing a vector of higher dimension. The respective values are used to initialize the components.
