bvec4()

Default constructor that produces a zero vector.

bvec4(const bvec4 & v)

Initialization by a vector.

Arguments

• const bvec4 & v - Value of the vector.

bvec4(unsigned char x, unsigned char y, unsigned char z, unsigned char w)

Initialization by scalars.

Arguments

• unsigned char x - X component of the vector.
• unsigned char y - Y component of the vector.
• unsigned char z - Z component of the vector.
• unsigned char w - W component of the vector.

bvec4()

Initialization by a vector and multiplier.

explicit bvec4(unsigned char v)

Initialization by a scalar.

Arguments

• unsigned char v - Value of the scalar.

explicit bvec4(const vec4 & v)

Initialization by a vector.

Arguments

• const vec4 & v - Value of the vector.

explicit bvec4(const dvec4 & v)

Initialization by a vector of double components.

Arguments

• const dvec4 & v - Value of the vector.

explicit bvec4(const ivec4 & v)

Initialization by a vector of integer components.

Arguments

• const ivec4 & v - Value of the vector.

explicit bvec4(const unsigned char * v)

Initialization by a pointer to the vector.

Arguments

• const unsigned char * v - Pointer to the vector.

void set(unsigned char x_, unsigned char y_, unsigned char z_, unsigned char w_)

Set vector.

Arguments
