WebJan 19, 2016 · 1 Answer. They are basically a function that given time returns 2 values for an audio single (left and right channel). The values go from -1 to 1. vec2 mainSound ( float time ) { return vec2 ( sin (time * 1000.0), sin (time * 1000.0) ); } You can see a more live example of a similar style of making sounds here. WebOn line 27, atan(y,x) will return an angle in radians between -PI and PI (-3.14 to 3.14), so we need to divide this number by TWO_PI (defined at the top of the code) to get values between -0.5 to 0.5, which by simple addition we change to the desired range of 0.0 to 1.0. The radius will return a maximum of 0.5 (because we are calculating the ...

WebNov 24, 2024 · Now to use these coordinates we need to map them to the 0-1 range. Since we're using radians, atan ranges from -pi to +pi and asin from -pi/2 to pi/2. Just some simple math to normalize them: #define PI 3.1415926. vec2 sphere_uv = vec2(yaw/PI*0.5+0.5, pitch/PI+0.5); You can use these UV coordinates to sample your texture!

WebUncomment lines 21-22 and see how we invert the st coordinates and repeat the same step() function. That way the vec2(0.0,0.0) will be in the top right corner. This is the digital equivalent of flipping the page and repeating the previous procedure. Take note that in lines 18 and 22 all of the sides are being multiplied together. This is equivalent to writing:
