Web3 de dez. de 2014 · to linear depth buffer I use following code in fragment shader Code: [Select] float n = 1.0; // camera z near float f = 27000000.0; // camera z far float z = texture ( DepthTex, TexCoord ).x; float d = (2.0 * n) / (f + n - z * (f - n)); FragColor=vec4 (d,d,d,1); however this does not work. Here is comparison of linear depth with and without log WebYou should try to use linear depth for the display, which after applying the projection matrix is (usually) stored in the w coordinate instead. Take that, divide by an appropriate number (depending on the scale of your game) to bring the numbers between 0 and 1 for your interesting depth and watch.
