Struct PySceneGraph 

pub struct PySceneGraph {
    pub nodes: Vec<PySceneNode>,
    pub meshes: Vec<(u32, PyMeshRenderer)>,
    pub particles: Vec<(u32, PyParticleRenderer)>,
    pub lights: Vec<PyLight>,
    /* private fields */
}

Hierarchical scene graph managing nodes, meshes, particles and lights.

Fields

nodes: Vec<PySceneNode>

All nodes in the scene.

meshes: Vec<(u32, PyMeshRenderer)>

Mesh renderers attached to node ids.

particles: Vec<(u32, PyParticleRenderer)>

Particle renderers attached to node ids.

lights: Vec<PyLight>

Lights in the scene.
