Using skeleton animations created in
Blender
In the
Animation with skeletons
recipe, we animated a model by directly changing the
position and rotation of its bones. This works great in an interactive scenery but isn't
a practical way to create animations. With Blender and other 3D tools, you've got a
large set of tools to create animations based on a specific skeleton and a set of bones.
In this recipe, we'll show you how you can play back a skeleton-based animation that
was created in Blender.
Getting ready
To use this recipe, you need to have Blender installed and enable the Three.js export-
er plugin. If you haven't done so, follow the steps from the
Creating and exporting a
model from Blender
recipe, in
Chapter 2
,
Geometries and Meshes
. Once Blender and
the Three.js export plugin have been installed, we need to create a skeleton-based
animation. Creating this in Blender is out of the scope of this topic, so we've provided
an existing model to demonstrate this recipe. To get started, perform the following
steps:
1. Open
Blender
and navigate to
File
|
Open
.
2. In the window that opens, navigate to the sources provided with the topic and
open the
crow-skeleton.blend
file, which can be found in the
assets/
models/blender
directory.
3. Once this file is open, you'll see a crow in the center of an empty scene like
this:
