It's a little bit more complicated than that, because this buffer is now an OpenGL texture and can be the result of rendering OpenGL graphics to the texture or compositing other textures together.
实际情况要比这要比这复杂一些，因为该缓冲现在是OpenGL纹理，也可以是OpenGL图形渲染结果的纹理，或者是其他纹理混合在一起的结果。
The root-level template works the same as that in the scatter plot example, rendering instructions for the elements and then calling showpage to render the contents of the graphics buffer.
root - level模板的工作原理与散点图示例中的工作原理相同，它将呈现元素的指令，然后调用showpage以呈现图形缓冲的内容。
If Z buffer can't be accessed as a texture, then depth is rendered in additional rendering pass, using shader replacement.
如果Z缓冲不能被以纹理的方式访问，那么深度将在额外的渲染处理中被使用着色器替代技术渲染。
Rendering without a fragment shader is useful when rendering only a primitive's default depth information to the depth buffer, such as when performing Occlusion Query tests.
当你只需要将图元的深度信息写入深度缓存时(例如在施展遮挡查询测试时)，不使用片段着色器的渲染过程就很有用。
Based on hardware-accelerated texture-based volume rendering algorithm, this paper proposed two methods for volume cutting, which are based on either depth buffer or discrete distance field.
在硬件纹理加速体重建算法的基础上，提出了两种模拟三维数据切割的方法：利用深度缓存实现和利用离散距离场实现。
After doing some reading, my best bet for deferred rendering is to use a depth buffer.
在做一些阅读，对于渲染我最好的办法是使用深度缓冲区。
Then the vector textures are performed image blending with texture of frame-buffer to generate rendering images, which are treated as the background images of IBFV algorithm instead of noise textures.
然后将这些矢量纹理作为IBFV算法中的背景图像，代替原来的噪声纹理与帧缓存中的纹理进行图像混合生成新图。
