I’m currently creating a three js app and I just want to ask if this is possible. So my goal is create a model in blender that’s like mesh #1 on the image below, export it thru blender gltf exporter by KhronosGroup, import it in Three JS and extrude the mesh in the middle to achieve mesh #2 in the image below.
The reason for doing this is I need to display a model that could have a dynamic length and let user control the length of the model thru the app’s UI.
Is this possible? If not, is there a way for me to achieve the behavior that I need to accomplish?
