Visualization Performance Meter

 

Visualization Performance Meter is a new QT sample which is intended to demonstrate the new "Graphic Performance Upgrade" functionality.

Performance measurement

A comparison is made between the use of the traditional graphic strategy and the use of the new graphic functionality.

Measurements are given in elapsed and CPU time for:

Manipulation of the graph plotting view

 

Test scenarios

I. Pre-defined test scenario (a sequence of the test shapes)

  1. Start the sample

  2. Press the "New 3D Viewer" button to open a new document

  3. Press the "Start automatic testing" button to set the displaying parameters, for example:

  1. Press the "Start" button

The sample will redraw the spheres in the shading mode from 1,000,000 elements to 1,000 elements with a step of 1,000 elements, make necessary performance measurements both for traditional (called "non-optimized" in the sample) and new ("optimized") graphical presentations of the shape or text visualization if the "Test Text Performance" box is checked.

II. Custom test scenario (an arbitrary shape)

  1. Start the sample

Traditional (non-optimized) mode:

  1. Press the "New 3D Viewer" button to open a new document

  2. Select " Load object/Sphere" from the pop-up menu (activated by right mouse click) to load the shape

The sample will build graphics for non-optimized graphical presentation of the shape.

  1. Close Document

New (optimized) mode:

  1. Press the "New 3D Viewer" button to open a New Document

  2. Press the "Turn on/off graphical presentation" button to turn on optimized graphical presentation of the shape

  3. Select " Load object/Sphere" from the pop-up menu (activated by right mouse click) to load the shape

The sample will build graphics for optimized graphical presentation of the shape.

NOTE: For most accurate performance measurements it is recommended to load one test shape per document.
