[x3d-public] Blender > Exporting rig transforms to HAnim?

[Brutzman, Donald (Don) (CIV)]

I too share that Blender->X3D conversion dream, Michalis!  8)

 

Given that X3D data types are clearly defined with thorough animation/interaction support, and given that you have indeed mapped glTF 2.0 rendering into X3D 4.0 capabilities, it is reasonable for anyone pursuing this effort to expect that complete success of rendering and animation is indeed possible.  Good to know when pursuing worthy goals.

 

all the best, Don

Blender->glTF exporter from Khronos (

https://github.com/KhronosGroup/glTF-Blender-IO/ , regularly synched to the version bundled with Blender) has great support for animations.

Simple animations (changing transformations), shape keys (this means "CoordinateInterpolator" in X3D), skinning (H-Anim in X3D). And it supports some more things too :) Like working textures, PBR, custom properties ("metadata" in X3D).

 

I indeed dream that someone will have time to upgrade the Blender->X3D exporter to add there these capabilities, and yes, looking at

Blender->glTF exporter is a reasonable approach for this.

 

Regards,

Michalis
