Marching Squares Algorithm
===
This project is realized for paper research on procedural content generation and aims to show how the marching squares algorithm works with interactive software.

## Features
+ Multichunk up to 4x4.
+ Option to use a compute shader.
+ Changing the single chunk resolution (1x1 to 500x500)
+ Moving and changing the noise settings from UI and the noise offset using the keyboard.
+ Enabling/Disabling vertex interpolation.
+ Enabling/Disabling UV mapping.
+ Choose between the use of the compute shader or the CPU.
+ Multiple default noise presets
+ Grid feature to monitor visually the vertices.

## Notes
(!) Grid feature it's expansive, use it with low chunk resolutions.

## Commands
Use WASD and DPAD to move the noise offset.
