*Description* 描述

A depth render texture format.

Depth 渲染纹理格式。

Depth format is used to render high precision "depth" value into a render
texture. Which format is actually used depends on the platform. On OpenGL it is
the native "depth component" format (usually 24 or 16 bits), on Direct3D9 it is
the 32 bit floating point ("R32F") format. When writing shaders that use or
render into a depth texture, care must be taken to ensure that they work both on
OpenGL and on Direct3D, see depth textures documentation.

Depth 格式用于高精度"depth"值到一个渲染纹理。实际使用哪种格式取决于平台。在 OpenGL 他是本地"depth
component"格式（通常是 24 或 16 位），在 Direct3D9 是 32 位浮点("R32F")格式。当写入着色器，使用或渲染到深度纹理，必须注意，确保它们是工作在 OpenGL 和 Direct3D 平台。

Note that not all graphics cards support depth textures. Use [SystemInfo.SupportsRenderTextureFormat](../SystemInfo/SystemInfo.SupportsRenderTextureFormat.html)
to check for support.

请注意，并非所有的图形卡支持的深度纹理。使用 [SystemInfo.SupportsRenderTextureFormat](../SystemInfo/SystemInfo.SupportsRenderTextureFormat.html) 检查是否支持。
