fractals's Introduction

Fractals

A Scala native fractal generator.

Sierpinski Triangle

First runners

You need to install llvm, sdl2 and bdw-gc to your system.

MacOS

brew install llvm sdl2 sdl2_ttf bdw-gc

Linux (tested on Ubuntu 18.04)

sudo apt install llvm
sudo apt install libsdl2-dev
sudo apt install libgc-dev

It is also needed clang and libunwind-dev.

sudo apt install clang
sudo apt install libunwind-dev

Running

After that sbt run will start and run the project.

For the implemented fractals you can add the number of the implementation as command line parameter. (for ex. sbt "run 3")

You can use left mouse button to add more detail/depth to the actual fractal. You can use right mouse button to iterate between the fractals. You can use middle mouse button to animate the actual fractal.

fractals's Issues

Show information about the current fractal

Display text on the screen about the current fractal(any or all of these):

The name of the fractal
The depth the fractal is being drawn at
Whether animation is on
How many lines have been drawn

Add the MIT license to LICENSE.md

Update the screenshots in the Readme file.

Add a solid layer behind the text for readability on mostly white fractals.

Create a turtle graphics system.

Create a Turtle Graphics system to make drawing from code more natural.

The implementation should create a list of lines resulting from the movements of the turtle.

Add a new fractal to the project!

The normalize method of the Vec2 class is slow

It calculates the length of vector twice when it should calculate it once and reuse the value.

Add text to the screen with instructions

Right mouse click is to skip to the next fractal
Left mouse click is to change the depth that the fractal is drawn
Middle mouse click is to toggle animated drawing

Add code documentation

Update screenshots.

Take new screenshots of each fractal and update the README.md

Add a screenshot for each fractal to the README.md

Struggling to run

After cloning the repo (and setting up clang etc). I run sbt run and get the following error:

[info] Compiling to native code (735 ms)
[error] /usr/bin/ld: cannot find -lSDL2
[error] clang: error: linker command failed with exit code 1 (use -v to see invocation)

Am I doing something wrong?
I am able to run a hello world project using ScalaNativePlugin
