sermonis / fast_spheres.txt
Created May 7, 2019 08:41 — forked from sebbbi/fast_spheres.txt
Fast way to render lots of spheres
Setup:
1. Index buffer containing N quads (each 2 triangles), where N is the max amount of spheres. Repeating pattern of {0,1,2,1,3,2} + K*4.
2. No vertex buffer.
Render N*2 triangles, where N is the number of spheres you have.
Vertex shader:
1. Sphere index = N/4 (N = SV_VertexId)
2. Quad coord: Q = float2(N%2, (N%4)/2) * 2.0 - 1.0
3. Transform sphere center -> pos

sermonis / nuxt.config.js

Headers of the page
- Nuxt.js uses vue-meta to update the headers and html attributes of your application.
- Nuxt.js configures vue-meta with these options:
{
keyName: 'head', // the component option name that vue-meta looks for meta info on.
attribute: 'data-n-head', // the attribute name vue-meta adds to the tags it observes
ssrAttribute: 'data-n-head-ssr', // the attribute name that lets vue-meta know that meta info has already been server-rendered
tagIDKeyName: 'hid' // the property name that vue-meta uses to determine whether to overwrite or append a tag

sermonis / A Nuxt.js VPS production deployment.md
Created December 23, 2020 07:15 — forked from DreaMinder/A Nuxt.js VPS production deployment.md
Deployment manual for a real-world project built with nuxt.js + koa + nginx + pm2

Example of deployment process which I use in my Nuxt.js projects. I usually have 3 components running per project: admin-panel SPA, nuxt.js renderer and JSON API.

This manual is relevant for VPS such as DigitalOcean.com or Vultr.com. It's easier to use things like Now for deployment but for most cases VPS gives more flexebillity needed for projects bigger than a landing page.

UPD: This manual now compatible with nuxt@2.3. For older versions deployment, see revision history.


Let's assume that you have entered fresh installation of Ubuntu instance via SSH. Let's rock:
