3d obejct frame work

Threestudio (base) https://github.com/threestudio-project/threestudio

• Mvdream-threestudio (modified) https://github.com/bytedance/MVDream-threestudio
  • Imagedream (more modified) https://github.com/bytedance/ImageDream

Threesudio
threestudio is a unified framework for 3D content creation from text prompts, single images, and few-shot images, by lifting 2D text-to-image generation models.

Mvdream-threestudio

• This code is forked from threestudio for SDS and 3D Generation using MVDream.
• For diffusion model and 2D image generation, check original MVDream repo.
• MVDream is create multi view images from text

Imagedream

• ImageDream introduces an image-prompt multi-view diffusion model tailored for 3D object generation. Unlike traditional text-only frameworks, it integrates image features as inputs, enhancing control over the 3D generation process.

3d Objects

stl

• Primarily used for 3D printing; contains only the surface geometry of a 3D object.
• Does not include color or texture data; supports binary and ASCII formats.
  obj
• Text-based format that includes vertices, texture coordinates, normals, and color.
• Does not support animations; widely used for static 3D models.
  fbx
• Supports complex scenes including 3D models, animations, rigs, and textures.
• Versatile, allowing for interchange between different graphics software

ply

• Stanford Triangle Format, was primarily developed at Stanford University as a flexible way to store 3D data from 3D scanners
• The format is structured to store geometric information such as vertices, faces, and other attributes like colors and normals.
• Can be Alternatives for stl,obj,3ds
  gltf
• Structure use JSON. Like a JPEG in 3D
• A full scene description contained in a JSON-formatted .
• glTF file that includes information about the node hierarchy, materials, and camera, as well as descriptor information about the mesh, animation, and other configurations.
• Binary files (.bin) containing geometry and animation data, as well as other buffer-based data.
• Image files for textures (.jpg, .png)
• Designed to achieve small file sizes, fast loading, full 3D scene representation, and scalability

glb (gltf binary)

• Binary file og gltf for more flexible and high speed

dae

• A DAE file is a digital asset exchange file format used to exchange data between interactive 3D applications.
• The file format is based on the COLLAborative Design Activity (COLLADA) XML schema, which is an open standard XML schema for exchanging digital assets between graphics software applications.
  splat
• So splat is kind a ply file for more efficient in web and mose important thing is created from 3d gaussian splatting model.

Unity 3D

unitypackage

• FIles project of unity, Like a zip file
  mesh
• Unity can import .fbx, .dae (Collada), .3ds, .dxf, .obj, and .skp files. These files are useful for:
  rigging
• fbx or dae
  material
• mat
  texture
• png,jpg ...

Extracting a Texture from a GLB

using blender or web (see video https://www.youtube.com/watch?v=GqPUEUw9im8&t=14s&ab_channel=Bucket'sTurds)
The quick way is to use the blender
