particle-system

Alright, so I have a good deal of experience with HTML and CSS, and some experience with Javascript (I can write basic functions and have coded in similar languages). I'm looking to start some visual projects and am specifically interested in getting into particle systems. I have an idea for something similar to Codecademy's name generator here ( https://www.codecademy.com/courses/animate-your-name/0/1 ) where particles are mapped to a word and move if hovered over. It seems as though alphabet.js is what's really behind Codecademy's demo however I can't understand exactly how they mapped the

Based on a previous question I had recently posted: How to create lines between nearby particles in ThreeJS? I was able to create individual lines joining nearby particles. However, the lines are being drawn twice because of the logic of the particle system. This is because of how the original 2D particle system worked: https://awingit.github.io/particles/ This also draws the lines twice. For each pair of particles connecting a line, the line is drawn. I do not think this is ideal for performance. How would I only draw a line once for each joining points? P.S. Here is exactly the effect I

I've been using 24bit .png with Alpha, from Photoshop, and just tried a .psd which worked fine with OpenGL ES, but Metal didn't see the Alpha channel. What's the absolutely most performant texture format for particles within SceneKit? Here's a sheet to test on, if needs be. It looks white... right click and save as in the blank space. It's an alpha heavy set of rings. You can probably barely make them out if you squint at the screen: exaggerated example use case: https://www.dropbox.com/s/vu4dvfl0aj3f50o/circless.mov?dl=0 // Additional points for anyone can guess the difference between the

I have a particle system where all the particles are positioned at the same coordinates and one after another, in random directions, they (should) start orbiting the center of the scene forming a sphere. What I managed to achieve until now is a group of Vector3 objects (the particles) that one after another start orbiting the center along the Z axis simply calculating their sine and cosine based on the current angle. I'm not that good at math and I don't even know what to look for precisely. Here's what I wrote: var scene = new THREE.Scene(); let container = document.getElementById('container'

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center . I searched the internet for information about particle systems and fire effects but I haven't found any good answers. Some games have some sort of movie shown as the fire, which is pretty good, but not for fires which are close to the viewer. How can I make realistic fire and smoke effects in a game? I am looking for good sample code

I'm trying to write a program that does some basic gravity physics simulations on particles. I initially wrote the program using the standard Javascript graphics (with a 2d context), and I could get around 25 fps w/10000 particles that way. I rewrote the tool in WebGL because I was under the assumption that I could get better results that way. I am also using the glMatrix library for vector math. However, with this implementation I'm getting only about 15fps with 10000 particles. I'm currently an EECS undergrad and I have had a reasonable amount of experience programming, but never with
