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。
is not a language for programming like java, python, javascript, etc. It is an API. Thus, what it does or used for is to move data in the central processing unit (CPU) to the Graphics Processing Unit (GPU) so that the renderer can render it. ...
What Is Batch Rendering? 每个游戏引擎都需要利用CPU生成游戏数据,然后在将这些数据传输到GPU,这样才能在屏幕上渲染出画面。当渲染不同的对象时,最好是将数据组织在一个组里,这样你就可以最小化CPU和GPU之间的调用,你同样需要最小化状态机改变的次数(过多的state change会把你程序性能拖成翔)。这些持有渲染数据...

When we say something is software functionality, it means that it is executed on the CPU instead of the GPU. When we say something is hardware functionality, it means that the feature is executed on dedicated hardware. For example, software rendering is done solely through the CPU and hardware...

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...
