OBJ/GLTF/VMD Viewer written in Java.

3D Viewer (OBJ, GLTF2.0 and MMD)

This software is 3D Viewer for OBJ, GLTF and MMD(PMX/VMD), written in JOGL. The code written here is no longer maintained but it will help you learn how 3DCG works as an implementation of Inverse Kinematics (IK), Virtual Texture Fetch (VTF) or something.

Usage

You can install this software from "Release" tab on this page. Execute the JAR files, then you can pick a 3D Model you want to see.

Format	Support	Note
OBJ	✅
GLTF	✅	GLTF2.0 models are mostly supported
PMX/VMD	Experimental

I've tested most of GLTF samples but several examples may not be rendered as intended. (I marked those features as TODO in the source code.)

Walkthrough

OBJ

• Rotate: Hold Mouse Button

GLTF

• Zoom In/Out: WSED Keys
• Move: Arrow Keys

PMX/VMD

• Zoom In/Out: WSED Keys
• Move: Arrow Keys

For Motion

• Play: P Key
• Reverse: O Key

• Prev/Skip: 1/2 Key

How can I get a model of these formats?

GLTF

You can grab GLTF models from this repository.

PMX/VMD

PMX/VMD is 3D format used in MMD(Miku Miku Dance). VMD includes motion data which is applied to PMX model. I recommend you to visit MMD community website since they have produced numerous characters or motions.

Are there any specifications of those formats?

Here are links you may want to read:

• GLTF 2.0 Specification
• Wavefront OBJ

NOTE: The specifications of PMX/VMD is unofficial.

Trouble Shooting

Some anti-virus softwares prevent this software from executing. If you have that situation, please go to settings then exclude the temporary directory on which jogamp_***.exe is running. It's also important that you have to assign high priority to java.exe.
