Struct nannou::geom::graph::node::Transform

pub struct Transform<S = DefaultScalar> where
    S: BaseFloat,  {
    pub scale: Vector3<S>,
    pub rot: Euler<Rad<S>>,
    pub disp: Vector3<S>,
}

A node's resulting rotation, displacement and scale relative to the graph's origin.

A transform is calculated and applied to a node's vertices in the following order:

1. scale: 1.0 * parent_scale * edge_scale
2. rotation: 0.0 + parent_position + edge_displacement
3. displacement: 0.0 + parent_orientation + edge_orientation`

Fields

scale: Vector3<S>

A scaling amount along each axis.

The scaling amount is multiplied onto each vertex of the node.

rot: Euler<Rad<S>>

A rotation amount along each axis, describing a relative orientation.

Rotates all vertices around the node origin when applied.

disp: Vector3<S>

A displacement amount along each axis.

This vector is added onto the position of each vertex of the node.
