Assignments on subject "Engineering and Computer Graphics" completed while studying at NSU. All the tasks done using C++/Qt6. All the projects were built using qmake (because QtCreator told me to use it :P).

• ECGPaint - small paint app. Allows to open images or create blank canvases, draw figures such as stars and polygons.

  • App uses Bresenham's algorithm to draw 1pt width lines.
  • App uses spans to implement filling (this algorithm called "Span Filling").

• ECGFilter - app with some image filters. The following filters have been implemented:

  • Monochrome filter.
  • Inversion filter.
  • Blur filter (gaussian blur for small kernel size and mean value blur for big kernel size).
  • Sharpening filter.
  • Embossing filter.
  • Gamma correction filter.
  • Edge detection (Roberts' and Sobel's algorithms).
  • Watercolor filter.
  • Dithering (Floyd's and ordered).
  • Pencil filter (filter that transforms picture into pencil drawing).

• ECGWireframe - app for modeling rotation figures. Using editor you can draw a B-spline, which will be rotated around axis and transformed into 3D figure.
