Genesis Engine
Genesis Engine made initially by Marc Pagès Francesch was forked by Javier D. Belda González and Silvino Medina Cardona for their third assignment in the Game Engines subject.

Description
For our third year at the Design and Development of videogames degree in the Game Engines subject we had had the objective to make a basic engine using several libraries such as Assimp, DevIL, Glew, ImGUI, Parson, PhysFS and SDL. after a general base in which we have a file system created similar to how unity works, with GameObjects, an inspector, scenes etc. For the third assignment we were given the task to create a high level system, in our case Shaders.
Shaders
Shader Pipeline
This last assignement consisted on creating a Shader Pipeline that would render a city using only shaders. Apart from that we also had to create a water demo producing simple moving waves using a vertex shader abd also changing the color to produce foam using a fragment shader.
So, to achive the goal of rendering the whole geometry using only shaders we started by drawing everything in red using one vertex shader and one fragment shader. Both types of shaders were imported to the engine to achive that. After that, we had to draw all the geometry of the city with their own color, so we added normals to the code and we changed the vert and frag file to make it render using only shaders.
Water Simulation
For the water simulation we created a fragment shader and a vertex shader.
The fragment shader changes the color of the water to simulate foam and darker areas by using cellular noise, the usage and the properties of this noise can be checked in the tutorial below.
he vertex shader simulates a waving movement with a simplified formula based in the theory of Franz Josef Gerstner about trochoidal waves, for more information check the links below.
