JavaScript => RenderToCubemap(cubemap: Cubemap, faceMask: int = 63): bool;
C# => bool RenderToCubemap(Cubemap cubemap, int faceMask = 63);

Description 描述

Render into a cubemap from this camera.

从这个相机渲染到一个立方贴图。

This is mostly useful in the editor for “baking” static cubemaps of your scene. See wizard example below.

这是非常有用的，可以在编辑器中烘焙场景的静态立方贴图。参考下面的向导实例。

Camera's position, clear flags and clipping plane distances will be used to render into cubemap faces. faceMask is a bitfield indicating which cubemap faces should be rendered into. Each bit that is set corresponds to a face. Bit numbers are integer values of CubemapFace enum. By default all six cubemap faces will be rendered (default value 63 has six lowest bits on).

相机的位置，清除标志和裁剪面距离将被使用来渲染到立方贴图表面，FaceMask是一比特域，表示那个立方贴图面应该被渲染，每个位对应于一个面。比特数是Cubemapface枚举的整型值。默认的所有六个立方贴图面都被渲染（默认值63的低6位是打开的）。

This function will return false if rendering to cubemap fails. Some graphics hardware does not support the functionality.

如果渲染失败这个函数将返回false，某些显卡不支持这个函数。

Note: This is a Unity PRO feature.

JavaScript:

	// Render scene from a given point into a static cube map.
	// Place this script in Editor folder of your project.
	// Then use the cubemap with one of Reflective shaders!
	class RenderCubemapWizard extends ScriptableWizard {
		var renderFromPosition : Transform;
		var cubemap : Cubemap;
 
		function OnWizardUpdate () {
			helpString = "Select transform to render from and cubemap to render into";
			isValid = (renderFromPosition != null) && (cubemap != null);
		}
 
		function OnWizardCreate () {
			// create temporary camera for rendering
			var go = new GameObject( "CubemapCamera", Camera );
			// place it on the object
			go.transform.position = renderFromPosition.position;
			go.transform.rotation = Quaternion.identity;			// render into cubemap		
			go.camera.RenderToCubemap( cubemap );
 
			// destroy temporary camera
			DestroyImmediate( go );
		}

		static function RenderCubemap () {
			ScriptableWizard.DisplayWizard.<RenderCubemapWizard>(
				"Render cubemap", "Render!");

This is used for real-time reflections into cubemap render textures. It can be quite expensive though, especially if all six cubemap faces are rendered each frame.

这个用于实时反射到立方贴图渲染纹理。这是非常耗时的，尤其是所有六个立方贴图面在每一帧中都被渲染。
