Display

Display Mode

(Visible only when Show Advanced Settings is on.)

This setting is controlled via two option buttons. The button on the left sets the type of display for the result.

• Visual
— Displays the solution as it would be viewed normally.

• Luminance
— Provides false-color display of the light reflected by surfaces. Colors range from red, representing the most reflected light, through to blue, which represents the least reflected light.

• Illuminance
— Provides false-color display of the light, excluding ambient, reaching surfaces. Colors range from red, representing the most incident light, through to blue, which represents the least incident light.

Color button

The button on the right sets the colors used.

• Color
— Output of the display is in color. Colors for Luminance and Illuminance range from Red > Orange > Yellow > Green > Blue.

• Grey Scale
— Output of the display is in grey scale.

Ray Trace Specular Effects

If on, the final display is ray-traced, instead of smooth-shaded. Ray-tracing of the final display is required to render the correct specular reflections and refractions in objects such as mirrors and windows. During the meshing phase, by default, the surfaces are displayed in smooth-shaded mode as they are computed.

Wiremesh Overlay

(Visible only when Show Advanced Settings is on.)

If on, lets you display a wireframe mesh over each surface during the meshing phase. This can be useful to visually inspect the size and orientation of the meshes used to create a solution. This setting is found also in the Radiosity dialog box.

Brightness Multiplier/Adapt to Brightness

These settings let you adjust the display brightness of a particle-traced solution.

Adjusting the Brightness using the slider in the Render tool settings, automatically updates these settings.

• Brightness Multiplier
— Lets you manually brighten or darken the image, multiplying all brightnesses by the specified scale factor.

The Select button to the right lets you select a point in the view as the median of the display range. Once you select a point, the Brightness Multiplier will be set to a value such that the brightness of the selected point is near the center of the display range the next time that the view is rendered.

Setting Brightness Multiplier to a value of 1.00 effectively turns off the Brightness Multiplier. With a value of 1.00 no brightness multiplier will be applied.

• Adapt to Brightness
— Lets you manually brighten or darken the image by specifying the intensity, in lumens per square master unit, of the middle point of the display range.

The Select button to the right lets you select a point in the view as the median of the display range. Once you select a point, the Adapt to Brightness value is set to the luminance of that point. When you next render a view, the display will be adjusted such that this brightness is near the center of the display range.

Display Range (lumens per square mu)

(Visible only when Show Advanced Settings is on.)

This color bar shows the range of brightness displayed for a solution, using the current brightness settings. The color bar can appear in three forms:

• Black to Yellow — for color visual display.

• Black to White — for grey scale display.

• Blue to Red — for color luminance, or illuminance, display.

As the values of the brightness controls are changed, the minimum and maximum luminance values will update accordingly.
