Real-Time Smoke Fluid Simulation Project

Project Introduction

This project aims to implement a real-time smoke fluid simulation. All components have been configured to run on GPUs using CUDA programming, which can be examined in the kernels folder. The project uses advanced fluid dynamics algorithms and volumetric rendering techniques for realistic smoke visualization. It is divided into three main parts: Fluid Solver, Renderer, and an OpenGL-based interactive window (GL).

Fluid Solver

The Fluid Solver contains the core algorithms for fluid motion, efficiently implemented in CUDA for GPU acceleration.

Renderer

The Renderer applies volumetric rendering techniques, also optimized with CUDA for GPU, to achieve realistic visualization of smoke.

OpenGL Window and Interaction - GL

The GL part creates a visualization window and handles user interactions, enabling users to view and interact with the smoke simulation.

Installation and Execution

Installing Dependencies

The project depends on several libraries listed in the CMakeLists.txt file. To install these libraries, follow these steps:

1. Download and install CMake if not already installed on your system.
2. Clone this repository to your local machine.
3. Open a command line tool and navigate to the project directory.
4. Run the cmake command to load the CMakeLists.txt file, which will automatically download and install the required libraries.

Running the Program

After installing the libraries, follow these steps to run the project:

1. Locate the gl executable file in the project directory.
2. Run the gl file to start the program.

User Interaction Guide

• The simulation starts automatically upon launching the program.
• Pause/Resume Simulation: Press the P key to pause the fluid motion. Press the O key to resume the simulation.
• Camera Control: Use W/S, A/D, Space, and Ctrl keys to move the camera for different views of the 3D simulation.
