## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)

## What it is
A collection of OpenGL ES tutorial demos in C/Objective-C with accompanying detailed blog posts on Jianshu. It covers basics through advanced topics like camera rendering, video mixing, filters, blending, and VR panorama playback.

## Use cases
- learn opengl es from scratch
- render camera feed with opengl es on ios
- play 360 vr panorama video with opengl es
- apply multiple image filters with shaders
- mix opengl rendering with video playback
- understand blend modes and shader blending
- build a mirror effect with opengl es

## When to choose
- you want a structured, blog-backed tutorial series for OpenGL ES
- you are an iOS developer learning GPU rendering with real demos
- you need working example code for video/camera rendering and filters

## When to avoid
- you need a production graphics library rather than learning material
- you target Vulkan, Metal, or modern OpenGL 4.x exclusively
- you need actively maintained code or official documentation

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: graphics, image-processing, video-processing, developer-tools
- domain: graphics, tutorials, mobile-development, computer-vision
- platform: cpp, c
- tags: opengl-es, gpu, shaders, rendering, tutorial-series, ios, camera, video-rendering, vr, panorama, video, mobile
