DRViewer means Dense Reconstruction Viewer, it's basically a lightweight 3D visualization tool based on modern graphic pipeline and C++11, designed for Simultaneous localization and mapping (SLAM in brief) and real-time MVS, capable of viewing structured 3D point cloud, camera trajectory and multiple input sources.
FinleyPan10. 3D file viewer(Blend da vinci)
This app lets you import 3d models and then you can change things as you want and can be exported as well.
Supported Files
- gLTF/GLB : gLTF/GLB is a neutral, open source format. The Khronos Group created this format for 3D web, AR, VR, Games and 3D advertising. Its the first really well-defined standard for 3D.
- FBX : FBX is a proprietary 3D file format. Kardara originally developed this format. AutoDesk then purchased them in 2006 and continued supporting FBX. It is widely used in the film and video game industry.
- OBJ : OBJ is a neutral 3D format when used as an ASCII variant. However, when used as a binary variant, it is proprietary. 3D printing, graphics, and 3D scanning all use this file format thanks in part to its ability to store geometry as well as color and texture information.
- STL : This 3D file format is most popular for 3D printing. It is a neutral 3D file format. This file format only stores geometry information.
GreaZeY11. iCn3D Structure Viewer
"I see in 3D" (iCn3D) Structure Viewer is not only a web-based 3D viewer, but also a structure analysis tool interactively or in the batch mode using NodeJS scripts based on the npm package icn3d. iCn3D synchronizes the display of 3D structure, 2D interaction, and 1D sequences and annotations.
Users' custom display can be saved in a short URL or a PNG image.
ncbi12. Opengl Model Viewer
This is a free and open-source simple 3D model loader, written in C and powered by OpenGL and assimp.
This project was made firstly to challenge myself on creating an application that used external assets from scratch, and secondly testing my skills on the C language, more-so on the memory management side of things as well as pointer arithmetic.
This application was intended to be a sort of 'halo project', where I sort out the functionality for loading models, then implement them elsewhere in other games/projects of mine.
logiiq13. OpenGLViewer
This project is a simple OpenGL 3D model renderer. It allows .obj and .mtl files to be opened and viewed. The core libraries used are GLEW, GLFW, and GLM.

A simple application to preview 3D models (currently .OBJ supported), where you can move the model around, flip normals, etc. It's implemented in Golang, and uses SDL2 to show the window, handle user's input, and write pixels into the screen buffer.
I made it from scratch to learn 3D rendering concepts, mathematics and algorithms involved to display a 3D textured mesh into the screen.
Features
- Fast 3D .obj file loading.
- Fast and smooth rendering.
- Simple camera system to move and rotate the object around.
- Buttons to change the resolution (to gain performance for more complex objects)
