Struct re_view_spatial::contexts::transform_tree_context::TransformInfo

pub struct TransformInfo {
    reference_from_entity: Affine3A,
    pub reference_from_instances: SmallVec1<[Affine3A; 1]>,
    pub twod_in_threed_info: Option<TwoDInThreeDTransformInfo>,
}

Fields

reference_from_entity: Affine3A

The transform from the entity to the reference space.

⚠️ Does not include per instance poses! ⚠️ Include 3D-from-2D / 2D-from-3D pinhole transform if present.

reference_from_instances: SmallVec1<[Affine3A; 1]>

List of transforms per instance including poses.

If no poses are present, this is always the same as reference_from_entity. (also implying that in this case there is only a single element). If there are poses there may be more than one element.

twod_in_threed_info: Option<TwoDInThreeDTransformInfo>

If this entity is under (!) a pinhole camera, this contains additional information.

TODO(#2663, #1025): Going forward we should have separate transform hierarchies for 2D (i.e. projected) and 3D, which would remove the need for this.

Implementations

impl TransformInfo

pub fn warn_on_per_instance_transform( &self, entity_name: &EntityPath, visualizer_name: &'static str, )

Warns that multiple transforms within the entity are not supported.

pub fn single_entity_transform_required( &self, entity_name: &EntityPath, visualizer_name: &'static str, ) -> Affine3A

Returns the first instance transform and warns if there are multiple (via Self::warn_on_per_instance_transform).

pub fn single_entity_transform_silent(&self) -> Affine3A

Returns the first instance transform and does not warn if there are multiple.

pub fn clamped_reference_from_instances( &self, ) -> impl Iterator<Item = Affine3A> + '_

Returns reference from instance transforms, repeating the last value indefinitely.

Trait Implementations

impl Clone for TransformInfo

fn clone(&self) -> TransformInfo

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TransformInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TransformInfo

fn default() -> Self

Returns the “default value” for a type.
