Why is Computer Graphics so Important?

The most important issue when selling a product is its design. Very often, when customers purchase products, they base their choice on the packaging rather than the contents. Psychologically speaking, attractive images immediately convey the notion of high quality contents.
We can see examples of this concept everywhere: think of the car industry, where aesthetics are paramount, or the enormous interest that novel cell phone or tablet designs can generate. In the movie industry, films with computer graphics and realistic 3D-effects often dominate the box office. The same notion goes for software, where an embellished interface, proper menu arrangement and up-to-date graphics and effects are all critical components of the overall user experience, and often form the deciding factors for one particular package over another. 

Bad visuals are “not a major concern”?


Not all software industries follow this trend, however. Analysis of widespread modeling software (CAD, CAE, CAM) shows that visualization is not given much thought because these systems do not implement the advanced 3D graphics technologies that, for example, computer games do.


In the gaming industry, players opt for games with efficient interfaces because, besides gameplay, there is enormous demand for rapid graphics and realistic effects. Visualization problems and shortcomings often lead user backlash with immediate repercussions on distribution and sales.

Computer modeling and simulation engineers often limit their visualization strategies to standard high-level graphics libraries based on simple 3D graphics (OpenGL and DirectX) technologies; they neglect visualization enhancements in preference of the development of computational algorithms and related mechanisms.


However this tendency has lost two major elements: quality representation of results and rendering speed. Poor quality representation of the results will deter any potential purchaser, be they the head of an engineering department or an individual client, and no arguments for the numerical accuracy of the results will dissuade them. Furthermore, low rendering speeds create an impression of disorganized and awkward computation. It is not therefore surprising that software offerings with low intrinsic qualities but better graphics will often outsell its competitors.


What do users remember?


The lack of a user-friendly interface and low-quality visual representation can often be interpreted as the difference between “Software for professionals” and “Software for everyone else”.

Project name: The development of software-studio for image processing using custom graphics filters.
Project implementation: 2012.
Technologies: C#, WPF 3.5, OpenDiagram, GLSL.
Client: Spectral Lights.
Project description:
Software-studio for image processing using custom graphics filters

The project was aimed at creating image processing software using graphics shaders. A sequence of GLSL shaders was created, each with a special graphic effect, such as digital noise or image blur, on an image. This shader structure was arranged in a special “visual node” network, which permitted. Such organization enabled the construction on a tree of effects for image processing; the interactive alteration of the parameters of each effect; the visualization of the application of a built tree of effects and the respective parameter settings.
The result was the creation of GLSL code conforming to the built tree of effects. This code allows the same effect to be processed on a video card for any other image, significantly reducing the processing time and relieving the CPU while allowing for the creation of professional series of effects for the film industry, amongst other things. The user interface was implemented with WPF technology for the Windows XP OS.

Project name: Acceleration of processed images in the Spectral Studio software.
Project implementation: 2010-2011.
Technologies: C#, С++, CUDA API (SDK).
Client: Spectral Lights.
Project description:
Acceleration of processed images in the Spectral Studio software

The main aim of the project was to accelerate the process of image rendering in the Spectral Studio © software, aimed at creating photorealistic images of objects from 3d models.

To facilitate this, a GPU-version of the “Aurora Renderer” module was created, including a new CUDA implementation of ray-tracer, using a specially created structure called BVH (Bounding Volume Hierarchy) to optimize and accelerate operation.

Once all the stages of the “Aurora Renderer” module were implemented, a tenfold acceleration of image creation on video cards was achieved.

Project name: Software for virtual human anatomy
Project implementation: 2010-2012.
Technologies: C++, OpenGL, C#, WPF 3.5, COM, TAO Framework, GLSL.
Client:QuintSysteme GmbH (Austria).
Project description:
Software for virtual human anatomy

The main aim of the project was to create special software to visualize inner parts of a human body; the lymphatic, blood-vascular, and excitatory systems; other anatomic components.

The software, developed with COM-technology, was interfaced with the software which controlled the medical equipment, to display both the current state of a patient and operational status of the equipment. The project included the development of special animation modes to simulate the operation of measuring equipment, to display electromagnetic field dynamics as well as the simulation of the moving parts of the equipment.

Highlighting, flashing and geometry and texture alterations were implemented to assist the diagnostic visualization of organs, with the help of shader graphics applications.
