crossfade

is there away to crossfade two glTF animations?

[prideout]

Yes, you can have many concurrent animations, each with their own time parameter. Simply call applyAnimation separately for each <animation>.

Thanks dear @prideout,

i just want to make sure we understand each other.., and this feature is really important when it comes to move from action to another smoothly..

say we have a skinned .glb character,.. with two clips inside, now, the crossfading plays the role of (blending-with-overlapping) the stored values of the transformation data (as keyframes for translate, rotate and scale) between both the end-of-the-first-clip and start-of-the-sec-clip, while the duration of morphing time depends on that intersection,..

in a 3d software we do the crossfading visually by overlapping two clips (on the same track) with specific number of frames (which considered the morphing time "crossfading time" between the the end of first clip, with the start of the second clip) as i mentioned; technically, it's fade-out and fade-in crossed with each others or overlapped over time,

so, does the applyAnimation do that?..

you may have a look at:

thanks in advance

Well, the Animator interface (which is what proffers applyAnimation) is a low-level stateless API for applying the individual animations that are defined in the asset. It is not a stateful interface like three's AnimationAction, which has functions like "play", "stop", "fadeIn". See also #3121.
