| std::ostream & | operator<< (std::ostream &o, const Vector3 &) |
3-component vector, used to represent a point or distance in 3D space.
This object is in general compatible with the SbVec3 template in the Inventor library. However it allows direct access to the x,y,z members, which imho makes math using this much easier to read.
| DD::Image::Vector3::Vector3 | ( | ) | [inline] |
The default constructor leaves garbage in x,y,z!
| DD::Image::Vector3::Vector3 | ( | const float | v[3] | ) | [inline] |
Constructor from an array of numbers.
| DD::Image::Vector3::Vector3 | ( | const double | v[3] | ) | [inline] |
Constructor from an array of numbers.
| DD::Image::Vector3::Vector3 | ( | float | a, |
| float | b, | ||
| float | c | ||
| ) | [inline] |
Constructor that sets all 4 numbers
| float& DD::Image::Vector3::operator[] | ( | int | i | ) | [inline] |
vector[0] is x, vector[1] is y, vector[2] is z.
| const float& DD::Image::Vector3::operator[] | ( | int | i | ) | const [inline] |
vector[0] is x, vector[1] is y, vector[2] is z.
| const float* DD::Image::Vector3::array | ( | ) | const [inline] |
Returns a ponter that can be passed to OpenGL
