Hi!
Anyone tried to use a logarithmic depth buffer?
I tried by adding the following in the shader (terrainblend.glsl), but it doesn’t work. Stuff is rendered in wrong order.
const float C = 1.0;
const float far = 1000000.0;
const float offset = 1.0;
gl_FragDepth = (log(C * vWorldPos.z + offset) / log(C * far + offset));
Maybe need to add same to another shaders?
I’ve looked through the shaders and I think terrainblend.glsl is the only one that put out fragment data (gl_FragColor and such) for the material/technique. But maybe I need to alter some shaders functions that deal with depth?
Hi, maybe you better try to use the Reversed Depth Buffer ? instead log zbuff
there is some examples of it (scroll topic almost to bottom) till words - Reversed Depth Buffer: habrahabr.ru/company/mailru/blog/248873/
Try to change GetDepth in Transform.glsl. This function is using everywhere.
Only it seems to me that this would cause problems when applying shadows
