    // In mediump, there are two problems computing 1.0 - NoH^2
    // 1) 1.0 - NoH^2 suffers floating point cancellation when NoH^2 is close to 1 (highlights)
    // 2) NoH doesn't have enough precision around 1.0
    // Both problem can be fixed by computing 1-NoH^2 in highp and providing NoH in highp as well

    // However, we can do better using Lagrange's identity:

Particle Swarm (WebGL + Geometry Buffers + GPU Noise)

Just a whole bunch of particles being rendered through geometry buffers (and modified on the GPU); also working on some better GPU-accelerated noise.

#Quixel Megascans Bridge API ####Updated: Aug 19th, 2016

We have developed an API to fetch information from the Bridge. The following is an initial list of endpoints any software will be able to retrieve information from.

• Megascans repository path
• Zip folder paths
• Get all assets (folder and json path)
• Get selected assets (folder and json path)
• Search results (folder and json path) against a string

Instagram photos by username for dashing

I struggled a while to create a dashing widget that would display images posted by a specific user. I build this upon the great foundation by @mjamieson that can be found here. To run this you will need a Dashing dashboard, the official Instagram ruby gem and access to the Instagram Developer API.

Getting set up

You will need to put some files into the right place in order to make this work:

• instagram.rb goes into the /jobs/ subfolder of your dashing installation

precision lowp float;

uniform sampler2D channel0;
uniform float time;

varying vec2 vTextureCoord;

// rendering params
const float sphsize = 0.8; // planet size
const float dist = 0.08; // distance for glow and distortion
