Today I took my first step in the vast domain of procedural generation. I tried to create a simple looking island.
An island as seen in the image above is simply some perlin noise where the highest values are concentrated in the middle.
I started by creating a circle. You can used the distance between two points formula to have points getting darker as they get further from the center. This is how I did it.
If you want to know how to create noise you should search the terms "Perlin noise" or "Simplex noise"
The noise blends with the circle making the map darker on the ends but lighter in the center.
The noise is too hard in the picture above to have good results, we need to smooth our image. I smoothed my image by setting every pixel to the average of their neighbors. This smoothing function was iterated 300 times in my final Island image.
I used a shader to color the island, but you can use what you want.
It was quite fun to create an island. I will try to read about procedural generation to showcase more impressive generations. If you like my content make sure you follow me :)
