"WebJan 3, 2015 · \$\begingroup\$ This is no complete answer, but a series of hints: you need an uniform to "animate" the effect - i.e. a time-like variable. Using that time value, you can shift the uv.xy with a (sin(time),cos(time)) offset vector. Of course, you must figure out the amplitudes of the sine and cosine offsets. I'd start with just offsetting the uv.y first and … " - Glsl sine wave

How to slow down the frequency of a sin() wave in GLSL?

WebThe Gerstner wave function is: Equation 9. Here Q i is a parameter that controls the steepness of the waves. For a single wave i, Q i of 0 gives the usual rolling sine wave, and Q i = 1/(w i A i) gives a sharp crest.Larger values of Q i should be avoided, because they will cause loops to form above the wave crests. In fact, we can leave the specification of Q …

WebJul 29, 2014 · For a standard sine wave, peak-to-peak amplitude ranges from -1.0 to 1.0 and wavelength is equal to 2π (frequency = 1). In the image above, you are viewing the sine wave from the "front", but if you view it from the "top" you can use the waves crests and troughs to draw a smooth greyscale gradient, where crest = white and trough = black.

WebGLSL Tutorial – Color Example. In the previous example we saw how to transform the geometry sent from the application to draw a model with a color defined as a constant in the fragment shader. In here we’re going to explore some more flexible ways of setting color for a 3D model. The first approach is to consider color as a vertex attribute.
