Function rerun::demo_util::color_spiral

pub fn color_spiral(
    num_points: usize,
    radius: f32,

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

• num_points: Total number of points.
• radius: The radius of the spiral.
• angular_step: The factor applied between each step along the trigonometric circle.
• angular_offset: Offsets the starting position on the trigonometric circle.
• z_step: The factor applied between each step along the Z axis.
