I’ve spent the last week or so rendering a simple ocean using gerstner waves but having issues with tiling, so I decided to start rendering them “properly” and dip my toes into the murky waters of rendering a heightfield using an iFFT. There are plenty of papers ...

WebReal-time rendering techniques have been migrating from the offline-rendering world over the last few years. Fast Fourier Transform (FFT) techniques, as outlined in Tessendorf 2001, produce incredible realism for sufficiently large sampling grids, and moderate-size grids may be processed in real time on consumer-level PCs.
