An OpenGL renderer for rippling water.

This project builds off of the LearnOpenGL series and ThinMatrix's tutorial on rendering water in OpenGL. It serves as my introduction to OpenGL.

Features include:

• 3D Model, texture, and normal-map loading with assimp
• Interactive view of scene that can be controlled with WASD keys and cursor
• API for placing, scaling, and rotating objects
• Point lights and directional lights
• Skyboxes
• Watery surfaces with reflection, refraction, ripples via dudv maps, the Fresnel effect, and transparency in shallow regions of water.

I developed this project on an x86 Mac, so the build system will probably favor people who are using those machines.

Clone repository: git clone --recurse-submodule https://github.com/rshiv2/glWater

This project uses assimp to load 3D models.

To compile assimp: cd external/assimp cmake CMakeLists.txt && make -j{<number of cores}

On linux, you can get the number of cores with nproc, on Mac, you can get it with sysctl -n hw.ncpu.

• Object picking and placing. It's currently really tedious to design scenes. My process was to nudge an object, compile, see the results, then repeat.
• Fix weird artifacts that occur at interface of water and terrain.
• Introduce bloom and deferred shading. I want to add lots more light sources, and make them look a bit more realistic.
• Speed up model loading. I need to profile this part of the code in order to be sure, but my guess is that assimp is taking a long time to load in 3D models.
