class
LParabolad¶ 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.

__init__(copy: LParabolad)
-
__init__(a: LVecBase3d, b: LVecBase3d, c: LVecBase3d) Constructs a parabola given the three points of the parametric equation: the acceleration, initial velocity, and start point.
-
assign(copy: LParabolad) → LParabolad¶
-
getA() → LVecBase3d¶ Returns the first point of the parabola’s parametric equation: the acceleration.
-
getB() → LVecBase3d¶ Returns the second point of the parabola’s parametric equation: the initial velocity.
-
getC() → LVecBase3d¶ Returns the third point of the parabola’s parametric equation: the start point.
-
readDatagram(source: DatagramIterator) → None¶ Reads the parabola from the Datagram using get_stdfloat().
-
readDatagramFixed(source: DatagramIterator) → None¶ Reads the parabola from the Datagram using get_float32() or get_float64(). See
writeDatagramFixed().
-
writeDatagram(destination: Datagram) → None¶ 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(destination: Datagram) → None¶ 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.setStdfloatDouble(). This is appropriate when you want to write a fixed-width value to the datagram, especially when you are not writing a bam file.
