User Interface

Window interface consists of 4 main areas:

  1. The Problem window is a tree of problems;
  2. The Properties window contains textual initial and calculated data of the selected problems and allows managing graphical output of these data;
  3. Viewports display data in graphical form;
  4. The Output window contains textual message on the calculation status.

Problem, Properties and Output windows can be connected to the boundaries of the Main window or can be left in floating mode in the Main window.

For less frequently accessed data such as global setting of colors and styles, the settings for generating reports is entered through pop up dialog boxes.

The SHAPE user interface follows standard Windows style guidelines, and is easy to learn and use.


Starting Calculation

When solving the reflector simulation problem, launch the calculation to get the light distribution of the system: luminous intensity or illuminance on the working plane. When solving the reflector synthesis problem, calculation seeks coordinates of the reflector profile, which provides the prescribed light distribution.


The Problem Window

The main purpose and advantage of this window is the ability upon designing to create different versions of problem-solving, comparing the obtained results to find the optimal solution.

The Problem window displays a tree of the current project with problems. A branch of each problem consists of 3 sections describing the optical system:

  • Light Source;
  • Reflector;
  • Illuminated Area.

Additionally, each problem has a section entitled Viewports. It can help you to specify how many windows will be presented in the viewports area and what information will be displayed in each one. You can specify from 1 to 4 windows. For each window one of the options can be set:

  • Optical scheme - general view, which includes a reflector, light source, ray-tracing and working plane;
  • Luminous intensity distribution of the light source;
  • Luminous intensity distribution of the entire system;
  • Illuminance distribution on the working plane;
  • Curve of the ray-tracing.

With a help of the Problem window, you access quickly any data from any problem solvable by you. There is a convenient mechanism for copying data from one problem to another, which shortens the time for entering parameters upon creating and modifying the optical system.


The Properties Window

This window displays the properties of the corresponding element selected in the Problem window. Data in Properties window may be shown in the form of textual fields, drop-down lists or additionally open windows containing arrays of curves.



Viewports display the initial and calculated data of the active problem in graphical form. In the properties of Viewports (in the window Problem),you can specify the window configuration, choosing one of the following:

The number of windows in Viewports can be from one to four. Each one can display certain characteristics of the problem: Optical Scheme, Luminous Intensity Distribution of Source, Luminous Intensity Distribution, Illuminance Distribution, or Ray-Tracing Function.


Zooming and panning the view

Initially, by default, the image (drawing of optical system, the graph of curves) is fully displayed in the window area. If is needed, you can change the scale by scrolling the middle mouse wheel in the active viewport: forward - to zoom in, backwards - to zoom out. The change of the magnification will occur with respect to the cursor position. If you hold down the Ctrl key, scaling will occur only in the vertical direction. While holding down the Shift button, image is scaled horizontally. This can be useful when you need to view the complexity of the curve shape better.

To display and examine different parts of the image, it is possible to pan the view. To do this, click on the left mouse button in the active viewport, and, holding it down, move the image in the desired direction.

Control Commands

Manage initial data of the optical system or illuminated area directly from the viewport. Parameters, such as start and final angles of the reflector, initial radius and angles of reflected rays at start and final points of the reflector, boundaries of the illuminated area are presented by a segment with a capture point, by which the parameter's value can be edited. Distance up to the working plane (if the illuminance distribution is calculated) can be changed by moving the line of the plane itself.
