当你在图形计算领域冒险到了一定阶段以后你可能会想使用OpenGL来绘制文本。然而,可能与你想象的并不一样,使用像OpenGL这样的底层库来把文本渲染到屏幕上并不是一件简单的事情。如果你只需要绘制128种不同的字符(Character),那么事情可能会简单一些。但是如果你要绘制的字符有着不同的宽、高和边距,事情马上就复杂了。根据你使用语
Mercury GPU 加速为项目设置。要启用该设置,请选择>,选择选项卡,然后将选项设置为。根据计算机和 GPU 的不同,显示的此类选项也可能不同。After Effects 支持以下 GPU 技术: OpenCL(仅限配备 AMD 或 Intel GPU 的 Windows) CUDA(仅限配备 NVIDIA GPU 的 Windows) ...
一些基本的概念: Rendering 渲染 : is the process by which a computer creates an image from models 由模型生成图像 Our models, or objects—we’ll use the terms interchangeably—are constructed from geometric primitives—points, lines, and triangles— that are specified by their vertices 模型或物体由...
During the early 2000s, GPU performance grew exponentially as more software features were moved to the GPU. The CPU became obsolete for rendering real-time 3D graphics since it could not keep up with GPU developments. In fact, the current method of rendering 3D graphics saw the CPU as such ...

A C++ class framework for developing OpenGL ES 2.0 applications for the Mali GPU. Mipmap A pre-calculated, optimized collection of bitmap images that accompanies a main texture, intended to increase rendering speed and reduce artifacts. Multi-ICE A JTAG-based tool for debugging embedded systems....
Uniforms are another way to pass data from our application on the CPU to the shaders on the GPU. Uniforms are however slightly different compared to vertex attributes. First of all, uniforms are global. Global, meaning that a uniform variable is unique per shader program object, and can be...
interface (API) that is very useful for rendering 2D and 3D vector graphics. This application program interfaces aid the establishment of communication with the graphics processing unit, which is also known as GPU for short. It is this communication that helps hardware-accelerated rendering. ...
