I'm trying to figure why shadow acne is happening at-all, I've tried looking at every video/resource I found online, some relate the issue to floating point rounding errors, other say it's about the size of the shadow map and if it could be infinitely large then this problem wouldn't occur, but … WebFormula for replicating glTexGen in OpenGL ES 2.0 GLSL. 1. ...

Hot Network Questions WebOct 15, 2012 · Generally, the approach for a point light which is shining light in all directions is to produce 6 shadow maps one for each axis. So you have your camera look along the +x, -x, +y, -y,+z and -z axes to make 6 shadow maps to create a cube map. Each axis's 'view' will be rendered with a 45deg field of view.

So instead: Select a unique per-light constant between 1 and … WebLayered rendering is possible since geometry shaders entered the OpenGL stage. The rough idea of a good omnidirectional shadow mapping (for example for pointlights) is to render the complete shadow map with a single draw pass, in order to reduce the amount of rendercalls, compared to six-pass rendering with traditional rendering to a cubemap.
