Raytraced display mode
Tools > Options > View > Display Modes > Raytraced
The Raytraced display mode sets the viewport to a rendered mode with Cycles, a real-time raytracer.
The Raytraced display mode applies Backdrop and Lighting settings from Render properties. The same settings can be found in the Rendering Panel that interacts with the Raytraced viewport.
Limitations: The Raytraced display mode does not display curvature analysis false-colors and vertex colors.
To access the Rendering Panel
- Run the Rendering command.
- On the Panels menu, select Rendering.
- Click the Panel options icon, and select Rendering.
To access Cycles options
The Cycles options manage Integrator, Session and Device settings of the Cycles rendering engine.
- On the Tools menu, select Options.
- In the Rhino Options dialog, select Cycles.
Raytraced display mode HUD
The Raytraced display mode HUD is located at the bottom of the Raytraced viewport.
Start/Pause
Click to pause or resume ray tracing.
Lock/Unlock
Locks the current view and pauses ray tracing.
Post effect toggle
Click to switch all post effects on or off.
Double-click to open the Post Effects page in Viewport properties.
Device information
Click to display information of the current render device.
Status
Display the rendering or completed status.
Time elapsed
The time used for the current rendering till now or the complete time.
Samples / Restriction
The amount of samples that have been raytraced and the restriction. Click to change the sample restriction.
Raytracing will stop when it reaches the sample restriction. Adding more samples will continue the ray tracing.
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
- Type or browse for the file name.
Gradient 2 colors
Blends between a top and bottom color.
Top color / Bottom color
To select a color
- Click the color swatch.
Gradient 4 colors
Blends between four colors starting from the corners of the viewport.
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.
Shading settings
Shade objects
Sets the viewport to opaque shaded mode.
X-Ray all wires
Shades with isocurves not obscured by objects in front.
Flat shading
Shades the current viewport with no smoothing so the individual render mesh faces are visible. 
See: FlatShade.
Shade vertex colors
Shades using an object's vertex colors.
See: ComputeVertexColors .
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.
Color and material
For the Rendered display mode, this setting is automatically set.
Rendering material
Shades using rendering material.
Advanced texture preview
Adds the ability to display:
- Multi-channel mappings
- Spherical and cylindrical display for low-polygon-count meshes, especially at the poles.
- Decals
- 3-D procedural textures
In the following illustration, the object has a wood material that has world coordinate mapping and a decal. With Advanced texture preview turned off, the preview display does not match the rendered output since it does not display the wood texture or the decal.
Advanced texture preview = off (left) and on (right).
Backface settings
Changes the color of the backface (the side opposite of the surface normal direction).
Use front face settings
No color change.
Cull backfaces
Surfaces viewed from the back will be transparent.
Use object's color
Surfaces viewed from the back use the color specified in the object's Properties.
Gloss
Sets the gloss for the backface material. This can be different from the front face material.
Transparency
Sets the transparency for the backface material. This can be different from the front face material.
Single color for all backfaces
All backfaces display a specified color regardless of the object color.
Gloss
Sets the gloss for the backface material. This can be different from the front face material.
Transparency
Sets the transparency for the backface material. This can be different from the front face material.
Single backface color
Sets a single color for all backfaces.
To select a color
- Click the color swatch.
Rendering material
Shades using rendering material.
Custom material for all backfaces
Click the button to specify the custom material.
Customize
Opens the Custom Object Attributes Settings dialog box.
