Abstract:
We present an improved parallax occlusion mapping algorithm for dynamic real-time lighting of surfaces including soft shadows, a directable LOD system and increased precision of the critical height field-ray intersection computation. We simulate the effects of motion parallax with perspective-correct depth at any viewing angle. Per-pixel ray intersections of a height field with view and light directions are performed to determine correct displacement on the surface as well as its visibility.
