Ocean Rendering

In this project, I used OpenGL to render simulated ocean waves. To create the simulation, I followed the approach outlined by Jerry Tessendorf in Simulating Ocean Water. A formal report of my progression through project is given in the PDF file included in the repo. The repo also includes 4 demos which can be compiled automatically using the included make file. If you prefer, I listed manual compilation instructions below.

Tiling

The tiling.cpp program renders a large ocean scene by tiling water mesh data stored in a FBO. This program also supports keyboard and mouse controls to allow the user to move around the scene. Use the following command to compile this program on Mac:

g++ -lglfw -lglew -framework OpenGL helperFunctions.cpp tiling.cpp -o tiling.out

On Windows or Linux:

g++ -lglfw -lglew helperFunctions.cpp tiling.cpp -o tiling.out

Finally, to run the program use the following command: ./tiling.out

Sky

The sky.cpp program renders a square water mesh and a surrounding skybox. The water is shaded using the skybox as an environment map. Use the following command to compile this program on Mac:

g++ -lglfw -lglew -framework OpenGL helperFunctions.cpp sky.cpp -o sky.out

On Windows or Linux:

g++ -lglfw -lglew helperFunctions.cpp sky.cpp -o sky.out

Finally, to run the program use the following command: ./sky.out

Render

The render.cpp program renders and animates a water mesh in 3D using the Fresnel equations to perform shading Use the following command to compile this program on Mac:

g++ -lglfw -lglew -framework OpenGL helperFunctions.cpp render.cpp -o render.out

On Windows or Linux:

g++ -lglfw -lglew helperFunctions.cpp render.cpp -o render.out

Finally, to run the program use the following command: ./render.out

Grayscale

The grayscale.cpp program renders and animates a wave height map as a 2D grayscale texture. Use the following command to compile this program on Mac:

g++ -lglfw -lglew -framework OpenGL helperFunctions.cpp grayscale.cpp -o grayscale.out

On Windows or Linux:

g++ -lglfw -lglew helperFunctions.cpp grayscale.cpp -o grayscale.out

Once compiled, the program can be run using the following command: ./grayscale.out
