Required Methods§

Source

fn draw<'a, 'pass>( &self, camera_bind_group_layout: &'a BindGroup, light_bind_group: &'a BindGroup, render_pass: &'pass mut RenderPass<'a>, )
where 'a: 'pass,

Source

fn to_clickable(&self, device: &Device, id: PickId) -> Box<dyn SceneNode>

Source

fn get_children(&self) -> &Vec<Box<dyn SceneNode>>

Source

fn add_child(&mut self, child: Box<dyn SceneNode>) -> usize

Adds a child node to the tree and returns the childs index

Source

fn remove_child(&mut self, idx: usize) -> Box<dyn SceneNode>

Source

fn set_local_transform(&mut self, idx: usize, instance: Instance)

Source

fn set_local_transform_all(&mut self, mutation: &mut dyn FnMut(&mut Instance))

Source

fn get_children_mut(&mut self) -> &mut Vec<Box<dyn SceneNode>>

Source

fn write_to_buffers(&mut self, queue: &Queue, device: &Device)

Source

fn update_world_transforms( &mut self, range: Range<usize>, parents_world_transform: &Vec<Instance>, )

Multiple instances of a parent can be passed down to multiple instances of multiple children. The argument parents_world_transform with a matching range size provides control over which instances are transformed.
