Opengl Es 31 Android Top Access
OpenGL ES 3.1 is a major update to the 3D graphics API designed specifically for mobile and embedded devices, officially supported starting with Android 5.0 (API level 21) . Its most significant contribution is bringing GPU compute
To utilize OpenGL ES 3.1, developers must declare the requirement in the application's AndroidManifest.xml file using the
Pro tip: Use glTexStorage3D (another ES 3.1 feature) for immutable textures. It informs the driver of exact memory requirements upfront, eliminating reallocation stalls. OpenGL ES 3
Leverage Compute Shaders for Post-Processing: Instead of using a traditional full-screen quad for effects like Bloom or HDR, use a compute shader for better cache locality and speed. Conclusion Capture vertex shader (or geometry) outputs and reuse
- Capture vertex shader (or geometry) outputs and reuse them to reduce CPU work.
The GLSurfaceView Wrapper
Most Android applications use GLSurfaceView. It handles the complexity of the EGL context for you.
