An abstract mathematical description of a parabola, particularly useful for describing arcs of projectiles.
The parabolic equation, given parametrically here, is P = At^2 + Bt + C.
| LParabolad | ( | ) |
Constructs a meaningless degenerate parabola.

| LParabolad | ( | VBase3D const | a, |
| VBase3D const | b, | ||
| VBase3D const | c | ||
| ) |
Constructs a parabola given the three points of the parametric equation: the acceleration, initial velocity, and start point.
| Point3D calcPoint | ( | double | t | ) |
Computes the point on the parabola at time t.
| VBase3D const getA | ( | ) |
Returns the first point of the parabola's parametric equation: the acceleration.
| VBase3D const getB | ( | ) |
Returns the second point of the parabola's parametric equation: the initial velocity.
| VBase3D const getC | ( | ) |
Returns the third point of the parabola's parametric equation: the start point.
| LParabolad operator= | ( | LParabolad const | copy | ) |
| output | ( | ostream | out | ) |
| readDatagram | ( | DatagramIterator | source | ) |
Reads the parabola from the Datagram using get_stdfloat().
| readDatagramFixed | ( | DatagramIterator | source | ) |
Reads the parabola from the Datagram using get_float32() or get_float64().
See write_datagram_fixed().
| write | ( | ostream | out | ) |
| writeDatagram | ( | Datagram | destination | ) |
Writes the parabola to the Datagram using add_stdfloat().
This is appropriate when you want to write the vector using the standard width setting, especially when you are writing a bam file.
| writeDatagramFixed | ( | Datagram | destination | ) |
Writes the parabola to the Datagram using add_float32() or add_float64(), depending on the type of floats in the parabola, regardless of the setting of Datagram.set_stdfloat_double().
This is appropriate when you want to write a fixed-width value to the datagram, especially when you are not writing a bam file.
| xform | ( | Mat4D const | mat | ) |
Transforms the parabola by the indicated matrix.
