CommandBuffer

class in UnityEngine.Rendering

切换到手册

描述

要执行的图形命令的列表。

命令缓冲区可保存渲染命令列表（“设置渲染目标、绘制网格等等”）。可将渲染命令设置为在摄像机渲染（请参阅 Camera.AddCommandBuffer）、光源渲染（请参阅 Light.AddCommandBuffer）期间的各个点执行，或者立即执行（请参阅 Graphics.ExecuteCommandBuffer）。

Typically they would be used to extend Unity's render pipelines in a custom way. For example, you could render some additional objects into deferred rendering G-buffer after all regular objects are done, or do custom processing of light shadow maps. See command buffers overview page for more details.

命令缓冲区创建后，可根据需要多次执行。

另请参阅：Camera.AddCommandBuffer、Light.AddCommandBuffer、CameraEvent、LightEvent、Graphics.ExecuteCommandBuffer、command buffers overview。

静态变量

ThrowOnSetRenderTargetThrow an exception when SetRenderTarget is recorded on a command buffer. This is mainly usefull when using native renderpasses to avoid inadvertently recording SetRenderTarget commands on the command buffer.

变量

name此命令缓冲区的名称。
sizeInBytes此命令缓冲区的大小，以字节为单位（只读）。

构造函数

CommandBuffer创建新的空命令缓冲区。

DispatchCompute添加用于执行 ComputeShader 的命令。
DispatchRaysAdds a command to execute a RayTracingShader.
DrawMesh添加“绘制网格”命令。
DrawMeshInstancedAdds a "draw mesh with instancing" command.The mesh will be just drawn once, it won't be per-pixel lit and will not cast or receive realtime shadows.如果 Material.enableInstancing 为 false，该命令不会立即失败并抛出异常，但如果检测到此类情况，则会记录错误并在每次执行命令时跳过渲染。如果当前平台不支持此 API（即，如果 GPU 实例化不可用），则会抛出 InvalidOperationException。请参阅 SystemInfo.supportsInstancing。
DrawMeshInstancedIndirect添加“通过间接实例化绘制网格”命令。
DrawMeshInstancedProcedural添加“通过实例化绘制网格”命令。Draw a mesh using Procedural Instancing. This is similar to Graphics.DrawMeshInstancedIndirect, except that when the instance count is known from script, it can be supplied directly using this method, rather than via a ComputeBuffer. If Material.enableInstancing is false, the command logs an error and skips rendering each time the command is executed; the command does not immediately fail and throw an exception.InvalidOperationException will be thrown if the current platform doesn't support this API (for example, if GPU instancing is not available). See SystemInfo.supportsInstancing.
