Another_OpenGL-ES

a simple script that shows how you can create an OpenGL ES app in C for Android that focuses on efficient rendering

create simple scripts using OpenGL ES as a basis for understanding how to optimize graphics rendering. The main focus is on ensuring efficient use of shaders, vertex buffer objects (VBO), and ensuring optimal frame rates.

Prerequisites

• Android NDK and SDK installed.
• EGL or OpenGL ES 2.0/3.0 Library.
• OpenGL window for rendering (usually SurfaceView on Android).

Explanation:

1. shader_utils.h and shader_utils.c - Helpers for creating shaders and programs.
2. main.c - OpenGL ES initialization, context creation, shader setup, and rendering loop setup for drawing simple objects.
3. Android.mk and Application.mk - Build scripts for Android NDK.

Extensions and Optimizations:

1. Batch Rendering: Use batch rendering techniques to reduce draw calls.
2. Shader Efficiency: Optimize shaders for better performance.
3. VBO (Vertex Buffer Object): Use VBO to move vertex data to the GPU.
4. Multithreading: Utilize separate threads for rendering and game logic.
5. Profiling: Use profiling tools like Systrace, GAPID, to narrow down and address bottlenecks.
