mortiniera / world-generation-project

World Generation computer graphics project using with basic features such as terrain generation, infinite heightmap, texture mapping, sky and water modelling, reflection and refraction plus optional camera mode implementations like bezier curves, FPS and fly through mode.

# Computer-

World Generation - Graphics Software Project

Authors : Thevoz Melik, Wagner Patrik, Mortiniera Thevie

Main Features :

• Feature 1 : Terrain Generation ( generate a heightmap for a terrain on the GPU, and then render it)

• Feature 2 : Texturing, Sky modelling, Water modeling, Reflection/Refraction

• Feature 3 : Basic camera control (Fly through mode, First-person-shooting mode, Bezier Curves to control camera paths)

  Extra Features :

• Water reflection : We flipped the camera along the horizontal plane to get a mirrored texture of the terrain and the sky that we use to texture the water by mixing it with a phong shading.

• Wave like animation : We use our perlin noise implementation to simulate waves that move according to the time.

• Infinite map : We build a big grid, each time we arrive to a limit close to the borders of this grid, we regenerate a new grid at this position. In our first implementation, we had an array with multiple grids to give the impression of an infinite size.

• Day/Sunset/Night : We can switch between three different day times by using the keyboard.

• Texture mixing : We mix our different textures in proportions depending on the height/normals to get a smoother transition between the layers and a more natural general feel.

Work split

• Patrik took care of the Bezier algorithms implementation, and everything related to the camera and infinite map.
• Melik and Thevie took care of the texturing (including the sky box) and the water (reflection) implementation
• The rest of the work (Perlin, ...) and most of the debugging was done all together.

External code references :

• Perlin noise was implemented by us based on the algorithm presented in the lecture slides, and not using the available source code. However we used a piece of code from this page : http://stackoverflow.com/questions/4200224/random-noise-functions-forglsl as a random generator for our Perlin.
• Ridged multifractal algorithm was found in these websites : https://engineering.purdue.edu/~ebertd/texture/1stEdition/musgrave/musgra ve.c https://github.com/jdupuy/fractalTerrain/blob/master/terrain.glsl
• Bezier curve implementation from lectures

Setup :

• OpenGL/C++
