What is the process for building a morph animation using sliders in three.js?

I recently completed a morph animation in Blender, where I created a transformation from a slim avatar to a fat avatar using shape keys. Now, I am attempting to export this animation to three.js and implement a slider that allows users to change the avatar's shape by dragging it right or left. However, I am unsure of how to program this functionality in JavaScript. If anyone could lend a hand, I would greatly appreciate it!

Answer №1

To achieve the desired effect of manipulating the vertices position, consider utilizing dat.gui as a slider and morphTarget. The source code from this example can provide insight into implementation.

For further information, refer to

In essence, the process involves pushing morphTarget to the geometry and utilizing mesh.morphTargetInfluences to control the impact of the morph target vertices.
