PTStudio: Simple 3D scene editor and renderer written in C++17

PTStudio is a light-weight, modular, and extensible 3D scene editor and renderer written in C++17. It is my personal hobby project to learn modern C++, OpenGL, Vulkan, and other graphics-related technologies. It is also a playground for me to experiment with new ideas and techniques.

Repository Tooling

• This project uses a hermetic tooling initialization process where all the tools are pulled in as Python packages, and python is used to perform various tasks like building, formatting, etc.
• To see the available tool commands, run pts.cmd --help.

Build & Test Instructions

• Run the repository tooling entrypoint pts.cmd build to bootstrap the build system (if needed) and build the project.
• Run the repository tooling entrypoint pts.cmd test to run the unit tests.

Prerequisites

• C++ Compiler Toolchain (GCC, Clang, MSVC, etc.)
• GPU driver with Vulkan and OpenGL support

Dependencies

• Make sure to clone the repository with all submodules:

git clone --recursive [repo url]

• If you've already cloned without --recursive, you can fetch submodules afterward with:

git submodule update --init --recursive

TODOs

Feature

- [ ] Rework the crazy reflection system
- [ ] Better scene graph (consider OpenUSD)

Code Improvement

- [ ] Reduce the cumbersome use of `tl::expected` and use exceptions in subsystem internals
- [ ] Renderers should be DLLs (this might be moot if moving to OpenUSD)
- [ ] Editing Improvements
    - [ ] put mesh loading in a separate thread
    - [ ] adaptive grid resizing
    - [ ] Ctrl+S to save scene (first time a file dialog will pop up, then subsequent saves will save to the same file)
    - [ ] Ctrl+D and Ctrl+C to duplicate selected objects
    - [ ] Ctrl+Z and Ctrl+Y to undo/redo
    - [x] camera should move faster the further away it is from the center
