Water RND #1
Water surfaces are an essential part of game projects. The approaches to implementing them are constantly evolving, where visual quality and performance are still in conflict. I’d like to share a bit about my experiments and thoughts on this topic. Trochoidal wave The shape of a trochoid is the key to understanding the mechanics of a water surface. A trochoidal wave is a model of a surface water wave where the water particles move in nearly circular or elliptical paths, creating waves that have rounded troughs and sharper crests. It’s a more realistic representation of ocean waves compared to a simple sine wave. In simple terms: The wave shape is smoother and more natural-looking, with sharper peaks and flatter bottoms. Water particles don’t travel far; instead, they move in looping paths — mostly in place. This kind of wave better represents how waves behave on the ocean surface under light to moderate wind conditions. Prebaked spectral waves My prebaked solution uses spectr...
