SpletPercentage Closer Filtering (PCF) The Percentage Closer Filtering technique uses a uniform size filter kernel, resulting in shadows with a uniformly soft edge. The PCF algorithm is very straightforward and fast, but does not achieve a realistic contact hardening effect. SpletThis tutorial describes a method (one of many) to reduce that problem. It is called Percentage Closer Filtering, or PCF. The idea is to sample from the shadow map around the current pixel and compare its depth to all the samples. By averaging out the results we get a smoother line between light and shadow.

SpletQt GUI. The Qt GUI module provides classes for windowing system integration, event handling, OpenGL and OpenGL ES integration, 2D graphics, basic imaging, fonts and text. These classes are used internally by Qt's user interface technologies and can also be used directly, for instance to write applications using low-level OpenGL ES graphics APIs.
