Water Surface Simluation
Jonathan Lew
About the Project
• Fascinated with water
surfaces
• An attempt to recreate
water surfaces in
OpenGL
• Explore various
methods
Techniques Researched
• Dual Buffers
– “Hackish” Approach that is easy and fast
– Problems: Not truly “round”, overlaps
– http://freespace.virgin.net/hugo.elias/graphics/x_water.ht
m (2D)
• Sombrero Equation
– Commonly used equation for ripple effect
– More realistic, but computationally more expensive
– http://adrianboeing.blogspot.com/2011/02/ripple-effectin-webgl.html
Advanced Techniques
• Will not be looking at them due to time
constrains
– Implicit Surfaces/”Blobby Model”
– Tessellation Shaders
– J. Tessenhorf’s Paper – Simulating Ocean Water
