WebApr 25, 2024 · Modern GPUs in fact have special function units specifically for calculating trigonometric functions. So any hand-written sine or cosine function is unlikely to perform any better than the intrinsic sin () / cos () function, no matter how many accuracy concessions you make. They are just insanely optimized in hardware. Share. 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.

WebJun 16, 2024 · To make the shader more interresting we’ll change the vertex shader. Instead of making the model just bigger, we’ll offset the y position based on the sine of the x position, making it wavy. void vert ( inout appdata_full data) { data.vertex.y += sin (data.vertex.x); } This results in big waves with a low frequency, so we’ll add two ...

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.
