Based on Jos Stam's paper, Real-Time Fluid Dynamics for Games.

• Quad Rendering:
  • Full-screen quad rendering from a texture.
• ImGui Integration:
  • Fully integrated ImGui interface.
• Fluid Simulator Header:
  • Header file for the fluid simulator based on the reference paper.
• Density and Velocity Step
  • Two-step fluid simulation.
• Texture Conversion
  • Velocity and Density fields are converted into renderable textures.
  • The density field is rendered, and users can display the velocity field texture by holding the C key.
• Density Injection
  • Users can add density in real time by holding the left mouse button.
• Velocity Injection
  • Users can add velocity by dragging their mouse in the desired direction while holding the right mouse button.
  • The distance dragged increases the injected velocity's magnitude.
• Velocity Vector Field
  • The velocity vector field can be visualized by holding the V key.
  • The magnitude of the arrows shows the magnitude of the velocity at that grid point.
  • Arrows are instance rendered and placed, oriented, and scaled in a vertex shader (velField.vert.glsl).
• Boundaries
  • Users can add boundaries to the fluid simulation grid by pressing the left mouse button and the left shift at the same time.
  • Boundaries can be removed by pressing the right mouse button and left shift at the same time.
  • Boundaries can be colored through an ImGUI color picker, leading for some artistic possibilities in the scenes.
• Custom Scenes
  • We have created three custom scenes (and an empty one) to showcase different fluid situations.
  • Further scenes can be easily created similarly, and we encourage users to do so.
  • For inspiration, look at crosswindscene.cpp, whirlwindscene.cpp, and waterfountainscene.cpp.

• OpenGL Integration:
  • Import <glad/glad.h> and <GLFW/glfw3.h> for OpenGL functionality.
• GLM Integration:
  • Import "glm_includes.h". This header conveniently includes multiple GLM headers.
• Project Structure:
  • Header files are located in $(ProjectDir)\includes.
  • Source files are located in $(ProjectDir)\src.
• Adding New Files:
  1. Right-click the project in the Solution Explorer.
  2. Select "Add Item."
  3. Ensure the files are added to the correct directories (includes for headers and src for source files).

• 3D.

• Memory Management:
  • std::vector<float> is used instead of raw pointers (float*) to avoid manual memory management.
• Main Loop Integration:
  • Call FluidSimulator::Tick() from the main update loop.
• Time Management:
  • FluidSimulator can internally use a clock to determine the time delta (dt) between Tick() calls.
• Sorry I didn't get as far as I hoped, but good luck and thanks y'all!
