How to use

WSAD, Arrow Keys, or Numpad 8, 6, 4, 2 to move; Plus and Minus (including numpad) to zoom; R to reset view.

How it works

The screen is divided up into tiles. Each of them is re-rendered when input happens.

The rendering is done on the CPU using a thread pool. Each of the threads gets a task allocated.

Key tasks are:

• Redraw tile (render it again with new paramaters)
• 'Desaturate tile' (Dim the tile to tell the user that it's out of date)

Implementation Notes

Uses SFML to not spend time implementing repetitive things.

Inter thread communication

Signalling the thread to wake up is done using a condition variable.

Mutexes are used for the queue.

Number of threads

The number of threads in minimum two, but otherwise automatically set to the amount of cores the operating system sees.

Drawing Manager

The Drawing Manager class handles drawing, input, and scheduling.

Mandelbrot static class

The Mandelbrot static class contains functions. Made static as it doesn't need to be instanced.

Logger Class

The logger class is for taking notes of time in CSV's, which can later be made into graphs.

Running benchmarks

Uncomment RunStatistics in the main function. This probably should've been made a mode.
