光线跟踪显示模式
工具 > 选项 > 视图 > 显示模式 > 光线跟踪显示模式
光线跟踪显示模式，其本质是 Cycles 渲染器的渲染模式，其光线跟踪是实时的。
光线跟踪显示模式应用渲染属性中的背景和照明设置。它与渲染面板中的设置是相同的，光线跟踪工作视窗与渲染面板中的设置是交互的。
限制: 光线跟踪显示模式不显示曲率分析假色也不显示顶点颜色。
访问 Cycles 选项
Cycles 选项管理 Cycles 渲染引擎的集成器、会话和设备设置。
- 在工具功能表点击选项。
- 在 Rhino 选项对话框中，选择 Cycles。
光线跟踪显示模式 HUD
光线跟踪显示模式 HUD 位于光线跟踪工作视窗的底部。
开启/暂停
点击以暂停或恢复光线跟踪。
锁定/解除锁定
Locks the current view and pauses ray tracing.
后期处理效果开关
设备信息
点击可以显示当前渲染器的信息。
状态
显示渲染或完成状态。
逾时时间
当前渲染已经使用的时间，或者渲染完成的总时间。
采样数/限制
光线跟踪的采样数和限制。点击以更改采样限制。
当达到采样限制时，光线跟踪将停止。设定更多采样数将延长光线跟踪。
Display mode options
Name
Name of display mode.
Viewport settings
Background
Specifies the viewport background color.
Use application settings
Use settings specified in Appearance -> Color Options.
Solid color
To select a color
- Click the color swatch.
Image file
Specifies an image for the viewport background.
Image file name

Top left color / Top right color / Bottom left color / Bottom right color
To select a color
- Click the color swatch.
Use render settings
Displays the colors and lighting used by the settings for background specified by the current renderer.
Transparent
Renders viewport backgrounds using black and a 0.0% alpha value. This works for rendered output and for ViewCaptureToFile.
着色设定
着色物件
设置工作视窗为不透明着色模式。
全部框线以 X 光显示
以着色网格显示曲面与网格，但位于其它物件后面的物件的框线不会被遮住。
平坦着色
以不在视觉上平滑处理的网格着色物件，可以看到着色网格的每一个网格面
请参考: FlatShade 指令。
着色顶点颜色
使以顶点色显示的物件表面有光影的明暗变化。
请参考: ComputeVertexColors 指令。
Allow ground plane display
Turns on the ground plane for the display mode.
Allow environment display
Turns on environment for the display mode.
Use linear workflow
Gamma correction for bitmap images is removed.The gamma correction is applied to the entire finished image. This can do a better job of processing the color in rendered images.
颜色和材质
对于渲染模式来说，此设置将自动设置。
渲染材质
使用渲染材质来着色。
高级贴图预览
可以显示以下内容：
- 多通道贴图轴
- 球形与圆柱形用于显示面数少的网格，特别是靠近极点的位置。
- 印花
- 3D 程序贴图
在下图中，物件有一个包含世界坐标贴图轴和印花木纹材质。关闭高级贴图预览后，预览显示和渲染输出的内容就不相同了，因为预览显示不显示纹理和贴图。
高级贴图预览关闭 (左) 与打开 (右)。
