To create a vector, we can pass in an X value and a Y value into the createVector() function. You can think of a vector as an arrow of some length that points towards some direction. One way we can more easily manipulate this relationship is with a vector, which is an object that has both a direction and magnitude. So far in this guide, we've drawn shapes and lines based on the relationship between the current mouse point ( mouseX and mouseY) and the previous mouse point ( pmouseX and pmouseY). Let speed = abs(mouseX - pmouseX) + abs(mouseY - pmouseY) One way we can create more continuous paint strokes out of circles is by connecting them together in a sequence without gaps in between, resulting in what looks like a string of beads():
So, given these constraints, we have to be smart about the way we paint in order for our strokes to look good. Here's another way of looking at it: the draw() function is like the hand that moves our paintbrush around the canvas, but our hand can only move so fast. In this way, each call to the draw() function is like a single animation frame, and repeating draw() over time creates a coherent picture. Since our marker() can only create one circle per call to draw(), the frequency that the browser can call draw() determines how smooth our marker() strokes look. Keep in mind that although we define how our strokes look with paintbrushes like pen() and marker(), it is the draw() function that drives the act of painting on the canvas. Gaps appear between the circles when you draw too quickly. You may have noticed that your paint strokes with the marker() brush don't look quite continuous. } Making better brushes and painting smoother strokes We'll draw a translucent circle wherever the mouse is currently located, which paints a line that feels similar to a felt-tip marker.
Instead of drawing a continuous pen line, let's switch things up. Now, let's explore more p5.js painting techniques and see what fun brushes emerge in the process! Mimicking a felt-tip marker pen
#DEADINDIAN PAINTBRUSH DRAWING CODE#
To make it easy for you to experiment with these techniques and create your own brushes, I've compiled all of these techniques as code snippets, which you'll find at the very bottom of this guide for future reference. To switch the paintbrush, simply swap pen() for a different paintbrush inside of the draw() function.Īlso, we'll use a variety of math techniques to define our brush strokes throughout this guide. As you follow along, you can use this same exact template code provided above. draw a line from current mouse point to previous mouse pointįor the rest of this guide, we'll focus on creating different paintbrushes with p5.js.

It looks like a brand-new coffee pot, and now I'm annoyed that I've spent so much time and effort trying to get this stupid pot clean. I dumped it out expecting to have to scrub a little or even run it through another time, but nope. I ran plain water through my coffee maker, dropped in two tablets, and let it sit for two hours. For 8 bucks, even if it doesn't work I'm not losing much. I found these on a random BuzzFeed article and figured eh, why not. Nothing has ever worked, and after 5ish years of using this specific coffee pot, it looked particularly atrocious. That said, I've tried everything imaginable to get the coffee stains out of our 'stainless'-steel coffee pot. Something has to be reeeaallly amazing or horrendously bad for me to write a review on it. Promising review: " So let me start by saying I don't typically write reviews.
