SbVec4f

SbVec4f()

Default constructor.

SbVec4f(const float v[4])

SbVec4f(float x, float y, float z, float w)

Constructor given vector components.

float dot(const SbVec4f &v) const

Returns dot (inner) product of vector and another vector.

SbBool equals(const SbVec4f v, float tolerance) const

Equality comparison within given tolerance –the square of the length of the maximum distance between the two vectors.

void getReal(SbVec3f &v) const

Returns the real portion of the vector by dividing by the fourth value.

const float * getValue() const

void getValue(float &x, float &y, float &z, float &w) const

Returns vector components.

float length() const

Returns geometric length of vector.

void negate()

Negates each component of vector in place.

normalize()

Changes vector to be unit length.

SbVec4f & setValue(const float v[4])

SbVec4f & setValue(float x, float y, float z, float w)

Sets the vector components.
