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.

) |
Constructs a parabola given the three points of the parametric equation: the acceleration, initial velocity, and start point.
Returns the first point of the parabola's parametric equation: the acceleration.
Returns the second point of the parabola's parametric equation: the initial velocity.

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().
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.
