Struct BvhFile 

pub struct BvhFile {
    pub skeleton: BvhSkeleton,
    pub frames: Vec<BvhFrame>,
    pub frame_time: f32,
}

A fully parsed BVH file.

Fields

skeleton: BvhSkeleton

Parsed skeleton hierarchy.

frames: Vec<BvhFrame>

All motion frames.

frame_time: f32

Duration of a single frame in seconds.

Implementations

impl BvhFile

pub fn frame_count(&self) -> usize

Number of frames in the file.

pub fn duration_seconds(&self) -> f32

Total duration in seconds.

pub fn fps(&self) -> f32

Frames per second.

pub fn root_translation(&self, frame: usize) -> [f32; 3]

Returns the root translation [x, y, z] at frame frame.

The root joint must have Xposition, Yposition, Zposition as its first three channels (the BVH standard for a 6-DOF root). If the root has no translation channels the function returns [0.0, 0.0, 0.0].

pub fn joint_rotation(&self, frame: usize, joint_idx: usize) -> [f32; 3]

Returns the Euler rotation (degrees) [x, y, z] for joint joint_idx at frame.

Only the rotation channels of the joint are inspected; translation channels are skipped.

pub fn interpolate_frame( &self, frame_a: usize, frame_b: usize, t: f32, ) -> BvhFrame

Linearly interpolate between frames frame_a and frame_b by factor t ∈ [0, 1].

pub fn sample_at(&self, time_seconds: f32) -> BvhFrame

Sample motion at time_seconds using linear interpolation between neighbouring frames.

Times before the first frame return the first frame; times beyond the last frame return the last frame.
