This guide walks Android developers through the concepts, tools, and step‑by‑step code needed to render video frames with OpenGL ES, apply custom shaders, and optionally build a custom FFmpeg‑based player for advanced animation effects.
This article introduces a live‑whiteboard demo built with OpenGL ES for iOS and Android, explains the implementation of multi‑channel rendering and multi‑texture approaches, compares their performance and flexibility, and provides complete GLSL and OpenGL code snippets for developers.
This article introduces a practical iOS OpenGL ES tutorial that demonstrates how to implement a 2D smart danmu system by separating foreground and background video layers, modifying IJKPlayer rendering, adding custom shaders, enabling blending, and optionally using CoreImage for face detection.
This tutorial explains how to transfer a Bitmap from Java to the native layer using the NDK, retrieve its pixel data with jnigraphics, create and configure an OpenGL texture, set up vertex and fragment shaders with proper texture coordinates, handle Y‑axis flipping on Android, and finally blend multiple textures for advanced rendering effects.
This guide explains the core concepts, integration steps, and troubleshooting tips for using the Faceunity (相芯) Beauty SDK with NetEase NERtc on Android and iOS, covering OpenGL ES basics, EGL/EAGL interfaces, three rendering schemes, resource management, and platform‑specific setup.
This article explores the feasibility of using Rust for UI rendering on Android by analyzing the rust-windowing ecosystem, detailing both software and hardware rendering approaches, explaining the integration of winit and glutin for cross-platform window and OpenGL context management, and demonstrating JNI-based communication with Android Surface components.
This article walks readers through the fundamentals of WebGL and OpenGL ES, explaining how JavaScript can drive hardware‑accelerated 3D graphics in browsers, covering rendering pipelines, shader basics, and the relationship between GPU, CPU, and modern web development.
This article explains the differences between GL threads and regular threads, how textures are bound to EGL contexts rather than threads, why textures cannot be shared across GL threads by default, and how to correctly share OpenGL data between threads on Android.
This article introduces the fundamentals of augmented reality, showcases various market applications and specific QuNar AR experiences, and delves into the technical underpinnings such as 3D mathematics, OpenGL ES 2.0 rendering pipeline, matrix operations, shader programming, and core sensor‑fusion algorithms.
GCanvas offers a JavaScript API compatible with HTML5 Canvas, delivering cross‑platform, high‑performance graphics rendering on Android and iOS by leveraging OpenGL ES, bypassing WebView limitations, and providing developers with a seamless Canvas‑like experience for mobile front‑end applications.
