APERTURE_TO_HALF_ANGLE

The factor that turns an opening angle in degrees into the half-angle arc takes.

APERTURE_TO_HALF_ANGLE: 0.008726646259971648

Import shape from shaders/std and use shape.APERTURE_TO_HALF_ANGLE.

Multiply a 0–360 aperture prop by it. It equals π/360.

Example

distance: ({x, y}, u) => arc(x, y, u('radius'), math.mul(u('aperture'), APERTURE_TO_HALF_ANGLE))
