Members
vec3 ( ) #
Default constructor. Produces a zero vector.vec3 ( const vec3 & v ) #
Constructor. Initializes the vector by copying a given source vector.Arguments
- const vec3 & v - Source vector.
vec3 ( const vec2 & v, float z ) #
Constructor. Initializes the vector using a given two-component vec2 source vector and a scalar.Arguments
- const vec2 & v - Two-component vector.
- float z - Z component of the vector.
vec3 ( float x, float y, float z ) #
Constructor. Initializes the vector using given float values.Arguments
- float x - X component of the vector.
- float y - Y component of the vector.
- float z - Z component of the vector.
explicit vec3 ( float v ) #
Constructor. Initializes the vector using a given scalar value: x=v, y=v, z=v.Arguments
- float v - Scalar value.
