Detailed Description

One animated channel: a keyframe curve driving one component of one node's transform.

Times are seconds from clip start. Only one of vec3_values / quat_values is populated, chosen by target

Member Function Documentation

keyframeCount()

auto assets::AnimationTrack::keyframeCount ( ) const -> size_t

inlinenodiscard

Returns

keyframe count, accounting for cubic spline storing three values per key

sampleVec3()

auto assets::AnimationTrack::sampleVec3 ( float time ) const -> glm::vec3

nodiscard

Evaluates this track at time, in seconds from clip start.

Clamps rather than loops - looping is the player's decision and it wraps the time first. A track with no keys returns identity, so a malformed one poses to something sane rather than to garbage
