Saw interesting question in the forums (link) about drawing plotter like data that would scroll up, got idea about custom rendertextures (since it was similar to this effect) Basic idea: – use CustomRenderTexture, double buffered so it can read from itself – draw color32 array […]

If you need to work with zip/rar/tar/gzip packages, can use SharpCompress to handle opening or creating those files. Compile SharpCompress DLL (unless you can find it online somewhere) Download project https://github.com/adamhathcock/sharpcompress Unzip and open in VisualStudio (i used 2017) Security warning, press ok Security warning, […]

Converted this (basic) algorithm into Unity c# https://docs.opencv.org/3.0-beta/doc/py_tutorials/py_feature2d/py_fast/py_fast.html FAST (Features from Accelerated Segment Test) is a way to detect corner features from an image. Source: *not optimizedhttps://gist.github.com/unitycoder/7649f62a6eceeb761db7f0092d9c3df1

Tested ray marching in Unity after watching this episode of The Coding Train. Source code:https://gist.github.com/unitycoder/7120e492deba748dba3d4e1e424d3c2a Usage:Set camera to 0,0,-10Projection: OrthographicThen Place spheres under empty gameobject, with sphere z values at 0

Converted this RANSAC 2D line fitting pseudocode into Unity c# http://www.visual-experiments.com/demo/ransac.js/ What is RANSAC? https://en.wikipedia.org/wiki/Random_sample_consensus Source code:https://gist.github.com/unitycoder/53495435c28853ef6522ff60d5c6a091 *Note this is not optimized at all, just a quick test Usage instructions:– Add this script to empty gameobject– Add gameobjects as a child of that gameobject (place […]

Saw this tip at #UniteKL18, fast way to get nearby objects using CullingGroup! (main image with 5000 gameobjects, searching objects within 3m radius) example source code: https://github.com/UnityCommunity/UnityLibrary/blob/master/Assets/Scripts/Docs/UnityEngine/CullingGroupExample.cs my example project: https://github.com/unitycoder/GetNearestObjectsWithCullingGroup Some notes on that: – You need to have MainCamera in the scene (as […]

Quick test for simple convolution filter with unity Texture2D (using c# script, not shader) Source project: https://github.com/unitycoder/ConvolutionFilter  

Converted this javascript quadtree (by The Coding Train) to Unity using texture2d *not complete with all the features yet though, but can add points by clicking texture with mouse.
