Detailed Description

Keyframe animation asset (.tanim), imported from glTF.

Author

dario

One clip plus the skins it poses, one file per animation the glTF defines. Sampled by toast::AnimationPlayer, GPU-skinned by renderer::SkinningPass

Bump _detail::animation_format_version on any layout change

Interpolation

enum class assets::Interpolation : uint8_t

strong

How a sampler interpolates between two keyframes, matching glTF's three modes.

Enumerator
cubic_spline	Cubic Hermite. Each keyframe stores three values (in-tangent, value, out-tangent) rather than one, so a cubic track's value array is 3x as long as its time array
