Software Model Visualizer

A CPU-based software rasterizer that loads and renders 3D glTF models in real time.

Features

• Loads .glb / .gltf 3D models
• Software rasterization
• Cross-platform (Windows/Linux)
• Custom unit test framework
• Custom math library

Usage

Program is run from the command line with the path to a glTF model file as an argument:

Software_Model_Visualizer $FilePath

Building the project

Requires CMake 4.0+ and C23 compatible compiler (GCC or Clang).
MSVC doesn't support C23 at this time.

To build the project, clone the repository using:

git clone 'https://github.com/kacper119p/Software-Model-Visualizer.git'

Enter the cloned repository's root folder:

cd ./Software-Model-Visualizer

Run the following commands to build the project (assumes cmake is in the PATH):

cmake -B $BuildDirectoryName

cmake --build $BuildDirectoryName --target Software_Model_Visualizer #for the main application

cmake --build $BuildDirectoryName --target Software_Model_Visualizer_Tests #for the tests

Tech Stack

• Language: C23
• Build System: CMake 4.0
• glTF Parser: cgltf
• Platform: Direct use of system APIs (Win32/X11, POSIX)
