LParabolaf

from acron.core import LParabolaf

class LParabolaf

Bases:

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.

__init__()

Constructs a meaningless degenerate parabola.

Constructs a parabola given the three points of the parametric equation: the acceleration, initial velocity, and start point.

assign()

calc_point()

Computes the point on the parabola at time t.

get_a()

Returns the first point of the parabola’s parametric equation: the acceleration.

get_b()

Returns the second point of the parabola’s parametric equation: the initial velocity.

get_c()

Returns the third point of the parabola’s parametric equation: the start point.

output()

read_datagram()

Reads the parabola from the Datagram using get_stdfloat().

read_datagram_fixed()

Reads the parabola from the Datagram using get_float32() or get_float64(). See write_datagram_fixed().

write()

write_datagram()

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.

write_datagram_fixed()

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()

Transforms the parabola by the indicated matrix.
