Trying to imitate old CRT TVs feel
This is an algorithm that I made on 2021, which I intended to update and improve.
Code is within a Visual Studio 2022 solution and projects. Download, check if the openFrameworks reference path is correctly set and execute.
The steps of the most important aspect of this algo are very simple:
- Load image and read color information for each channel
- Map those color values in a 0-to-1 sliding scale.
- Use those values to control parameters such as size and alpha of a figure (I do this)
- Repeat for each pixel in the image
Additionally, I use that sliding scale to make some animation transitions between images.
