SpletThe Adreno SDK for OpenGL ES contains several working samples, tutorials and demos covering OpenGL ES features, ranging from OpenGL ES 2.0, 3.0 + AEP, and 3.1. The following lists describe the samples included in this SDK which are all built on top of a common OpenGL ES Framework that can be leveraged to create new samples and … 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.

SpletPCF采样优化. 基于这个思路，我们首先可以将3x3的PCF采样范围扩大到至多16个像素。宇宙人都知道一次SampleCmpLevelZero调用，可以得到4个有效像素。因此理论上来说，4次采样，最多可以覆盖4x4=16个像素。我们可以将4个采样点位置按如下进行分配:

Splet28. jul. 2016 · The OpenGL specification does not dictate the specific algorithm to be used when linearly interpolating depth comparisons. However, it generally describes it as: The details of this are implementation-dependent, but r should be a value in the range [0,1] which is proportional to the number of comparison passes or failures.
