killop / VGO

VGO is a 3D data format for Unity that can store Mesh, Texture, Material, Collider, Rigidbody, Cloth and Particle information.

VGO

VGO is a new type of 3D data format.

Features

• You can save basic information of 3D model such as Node, Transform, Rigidbody, Collider, Mesh, BlendShape, Material, Texture.
• You can also save the information of Human Avatar, SpringBone, Animation, Cloth, Light, ParticleSystem, Skybox for use in Unity.
• You can also save the information of BlendShapePreset for use in the application.
• The file format uses IFF chunk as the base.
• Use JSON, BSON, Binary as internal data.
• The geometry coordinate system can have both right-handed and left-handed data.
• It is a specification that allows its own definition extension (chunk, schema).
• It is designed to support partial encryption.
• Resources are basically included in a file, but they can be cut out in another file.
• Resources can compress data with sparse, and have their own definition of the more powerful sparse.
• There is no direct compatibility with glTF.
• It is possible to convert to other formats including glTF by expanding the data in Unity Editor.
