One difference between them is that the triangular mesh uses random triangle offsets and random colors, whereas in a real-world design we seldom see complete randomness. That’s where noises, such as the Perlin noise introduced in day 5, can come useful.
Below are two triangular meshes with complete randomness and with Perlin noise. As you can see, the image generated with Perlin noise features smoother triangle offsets and color shifts.
When you are all done, post your work on Twitter with the hashtag #codecember and #day8. Remember to include a link to the source code, so others can learn from your creation. We look forward to seeing your sketch!
