12 ? LightT ools 7.1 Release Notes
Improvements to the LightTools User Interface
The LightTools addition to the My Places toolbar provides links to as many as five locations that are specific to LightTools operations. You can click these links to quickly navigate to a folder of interest. The top two links are fixed links to the Shared Files folder and the LTUser folder. You can have up to three additional links that provide access to recently used files, determined by the last three folders you accessed when you performed an open or save operation such as opening or saving a model, importing or exporting a file for data exchange, or saving a material. These links are persistent across LightTools models and across sessions.Main Menu Changes
The menu previously labeled RGB Raster Chart has been changed to True Color Raster Chart. Because it is based on tristimulus values calculated from the spectral content collected on the receiver, this raster chart closely matches the physical properties of the light and the model properties.
In addition, the menu has been moved from the third level to the second level under the Analysis menu,
directly under each analysis type, as shown in the following figure.

Data Field Renamed on Ray Segment Properties Tab
On the Properties tab for a nonsequential ray segment, a calculated field in the Transmittance Along Ray section has been renamed and moved to a different location on the tab. Because it shows the relative flux of the ray prior to the surface, the Cumulative field has been renamed Prior to Surface, and it has been moved
to the top of the Transmittance Along Ray section, as shown in the following figure.System Navigator after clicking the plus sign next to CubePrimitive_1System Navigator after selecting Expand All menu for CubePrimitive_1Old NS Ray Segment Properties Tab New NS Ray Segment Properties Tab

New Capability to Display Illuminance Data in the 3D Design View
New Capability to Display Illuminance Data in the 3D Design View
Illuminance raster output for receivers on dummy planes can now be displayed in the 3D Design view. This feature is useful for visualizing, relative to the model geometry, the orientation and distribution of illuminance data across a receiver.Known Limitations
The following limitations to this feature exist in this release.
?
Output is only supported for receivers on dummy planes.?
Illuminance data obtained from a backward simulation cannot be displayed.?Output is displayed in pseudo-color only.
Displaying Illuminance Data in the 3D Design View
Before displaying illuminance output in the 3D Design view, your model must have the following characteristics:
?
At least one source.?
At least one receiver defined on a dummy plane.?
Illuminance data collected by a forward simulation for the receiver(s) of interest.To display the illuminance data in the 3D Design view:
1.In the System Navigator, double-click the Illuminance Mesh data in the forward simulation for the
receiver.The Properties dialog box for the illuminance mesh is displayed, with the Properties tab in the foreground.
2.
On the Properties tab, select the Show Simulation Data check box.
New Capability to Display Illuminance Data in the 3D Design View
3.Click OK.
Alternatively, a quick way to display the illuminance data in the design view is to right-click the
illuminance mesh in the System Navigator and select Show Simulation Data
on the shortcut menu.
The illuminance raster output is displayed on the selected receiver in the design view. The output is displayed with a transparency factor of 25%, which cannot be modified. The resolution of the display is
controlled by the illuminance mesh dimensions. In addition, the display boundaries are controlled by the illuminance mesh boundaries; this means that the output in the 3D Design view will be the size of the mesh, regardless of the size of the receiver dummy plane.
The following figure shows an example of illuminance raster data that is displayed in the 3D Design view for four dummy planes. Note that the starting and ending values in each illuminance chart are determined
by the mesh data set of the associated receiver.
