def bounce_lerp(a, b, t)

A linear interpolator that bounces between a and b as t goes above 1.0.

PARAMETER	DESCRIPTION
a	Start value (t == 0). TYPE: float
b	End value (t == 1). TYPE: float
t	Interpolation coefficient. TYPE: float | ndarray[Any, dtype[Any]]

def build_color_grid(x_count=10, y_count=10, z_count=10, *, twist=0)

Create a cube of points with colors.

The total point cloud will have x_count * y_count * z_count points.

PARAMETER	DESCRIPTION
x_count	Number of points in each dimension. TYPE: int DEFAULT: 10
y_count	Number of points in each dimension. TYPE: int DEFAULT: 10
z_count	Number of points in each dimension. TYPE: int DEFAULT: 10
twist	Angle to twist from bottom to top of the cube TYPE: float DEFAULT: 0

def build_color_spiral(num_points=100, *, radius=2, angular_step=0.02, angular_offset=0, z_step=0.1)

Create a spiral of points with colors along the Z axis.

PARAMETER	DESCRIPTION
num_points	Total number of points. TYPE: int DEFAULT: 100
radius	The radius of the spiral. TYPE: float DEFAULT: 2
angular_step	The factor applied between each step along the trigonometric circle. TYPE: float DEFAULT: 0.02
angular_offset	Offsets the starting position on the trigonometric circle. TYPE: float DEFAULT: 0
z_step	The factor applied between each step along the Z axis. TYPE: float DEFAULT: 0.1
