Enum VelocityDist 

pub enum VelocityDist {
    Fixed([f32; 3]),
    UniformBox {
        min: [f32; 3],
        max: [f32; 3],
    },
    UniformCone {
        axis: [f32; 3],
        half_angle: f32,
        min_speed: f32,
        max_speed: f32,
    },
}

Distribution used to assign an initial velocity to a newly spawned particle.

Variants

Fixed([f32; 3])

Every particle gets the same velocity.

UniformBox

Velocity is sampled uniformly inside an axis-aligned box.

Fields

min: [f32; 3]

Minimum corner of the velocity box.

max: [f32; 3]

Maximum corner of the velocity box.

UniformCone

Velocity direction is sampled uniformly inside a cone around axis, magnitude in [min_speed, max_speed].

Fields

axis: [f32; 3]

Cone axis direction.

half_angle: f32

Half-angle of the cone in radians.

min_speed: f32

Lower bound on sampled speed.

max_speed: f32

Upper bound on sampled speed.
