Computer geometry and graphics

Here you can find some problems and solutions for Computer Geometry and Graphics course.

We use Python and PyQT for the GUI.

As advice to you, better use C++ with Qt for the GUI, because it is much faster and more convenient.

You may think: "ooohhh, man, idk C++". But trust me, it will be easier too you.

If you still want Python, try to use numpy and minimize for loops in your code.

Please don't look this code, it is very bad, actually PNG and anti-aliasing.

Another part works normal, but slow.

All problems you can find here.

If you want to use some pictures, you can find them here.

Which parts are done?

• PNM format support
• Color spaces
• Gamma correction
• Drawing bitmap lines with anti-aliasing applied

Work so bad

• Pseudo-tinting of images, Dithering

Have a mistake in the 8x8 ordered dithering

• Image scaling

• Implemented only 3/4 algorithms
• Shift works only in integer coordinates

• PNG format support

Works like a separate widget, not like a part of the program

• JPEG format support
• Image histogram
• Image filtering
