Panics

Will panic if the translation and rotation do not cover the same number of timesteps

pub fn new_from_npz(anim_npz_path: &str, config: AnimationConfig) -> Self

Panics

Will panic if the path cannot be opened Will panic if the translation and rotation do not cover the same number of timesteps

pub async fn new_from_npz_async( anim_npz_path: &str, config: AnimationConfig, ) -> Self

Panics

Will panic if the path cannot be opened Will panic if the translation and rotation do not cover the same number of timesteps

pub fn new_from_json( path: &str, _anim_fps: f32, config: AnimationConfig, ) -> Self

Panics

Will panic if the path cannot be opened Will panic if the translation and rotation do not cover the same number of timesteps

pub fn new_from_smpl_codec( codec: &SmplCodec, wrap_behaviour: AnimWrap, ) -> Option<Self>

Create an Animation component from a SmplCodec

Panics

Will panic if the individual body part poses in the codec don’t have the correct shape to be concatenated together into a full pose for the whole body

pub fn new_from_smpl_file(path: &str, wrap_behaviour: AnimWrap) -> Option<Self>

Create an Animation component from a .smpl file

pub fn new_from_smpl_buf(buf: &[u8], wrap_behaviour: AnimWrap) -> Option<Self>

Create an Animation component from a .smpl buffer

pub fn num_active_joints(&self) -> usize

pub fn num_animation_frames(&self) -> usize

pub fn advance(&mut self, dt_raw: Duration, first_time: bool)

Advances the animation by the amount of time elapsed since last time we got the current pose

pub fn has_expression(&self) -> bool

pub fn get_smooth_time_indices(&self) -> (usize, usize, f32)

pub fn get_current_pose(&mut self) -> Pose

Get the pose and translation at the current time, interpolates if necessary

pub fn get_pose_at_idx(&self, idx: usize) -> Pose

Get pose at a certain frame ID

pub fn get_current_expression(&mut self) -> Option<Expression>

Get expression at current time

pub fn get_expression_at_idx(&self, idx: usize) -> Option<Expression>

Get expression at a given frame ID

pub fn slice_time_range(&self, start_sec: f32, end_sec: f32) -> Animation

pub fn align_y_axis_quadrant( &mut self, current_axis: &Array1<f32>, desired_axis: &Array1<f32>, )

Rotates multiple of 90 until the axis of the body is aligned with some arbitrary vector

pub fn get_cur_time(&self) -> Duration

pub fn set_cur_time_as_sec(&mut self, time_sec: f32)

pub fn pause(&mut self)

pub fn play(&mut self)

pub fn duration(&self) -> Duration

Duration of the animation

pub fn is_finished(&self) -> bool

pub fn nr_repetitions(&self) -> u32

pub fn translate(&mut self, translation: &Array1<f32>) -> Result<(), String>

Shift each frame of the animation by the given translation vector.

Errors

Will return Err for array size mismatch.

Trait Implementations

impl Clone for Animation

fn clone(&self) -> Animation

Returns a duplicate of the value.

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

Performs copy-assignment from source.
