This is a real-time cloth simulation system that allows users to adjust scene parameters like cloth size and stiffness, modify method parameters such as timestep and iteration count, and apply external wind forces to the cloth.

Implemented cloth simulation method:

• XPBD
• PBD
• XPBD with small substeps
• Verlet Integration
• Explicit Euler Integration
• Semi Implict Euler Integration

Usage

• Escape/ESC: Exit
• W, A, S, D: move camera
• Mouse Wheel: control camera zoom(height)
• P: Execute/Pause the simulation
• T: Step 1 time, this key will unconditionally pause the simulation
• M: Take a screenshot of current frame.
• N: Record all nodes' position into text and step 1 time.
• Z, X, C: Switch the render mode as DRAW_NODES, DRAW_LINES and DRAW_FACES
• R: Reset the scene
• Up, Down, Left, Right: Adding force to the cloth.

Test Environment

• Windows 10
• Visual Studio 2022 with C++17 standard
• OpenGL >= 3.3

Note: it not means you should have exactly the same environment.

Dependencies

• glm
• glad
• glfw
• glTools
• freetype
• FreeImage (optional, only used for screenshot)

Note: opengl32.lib, glfw3.lib and freetype.lib should be linked, and besides including corresponding library, you should also add glad.c into your project.
