| Pitfall | Fix | |---------|-----| | Compute shader workgroup size too large | Use local_size_x = 64 (safe for all ES 3.1 GPUs) | | Ignoring GL_EXT_robustness | Handle device-driver crashes gracefully | | Not checking extension strings | Always query glGetString(GL_EXTENSIONS) – ES 3.1 core ≠ all features |
For most developers targeting mid-range to high-end Android, mastering OpenGL ES 3.1 remains a valuable, practical skill.
To create an OpenGL ES 3.1 application on Android, follow these steps:
int fragmentShader = GLES30.glCreateShader(GLES30.GL_FRAGMENT_SHADER); String fragmentShaderCode = "void main() gl_FragColor = vec4(1.0, 0.0, 0.0, 1.0); "; GLES30.glShaderSource(fragmentShader, fragmentShaderCode); GLES30.glCompileShader(fragmentShader);
#version 310 es layout(local_size_x = 256) in; layout(std430, binding = 0) buffer ParticleBuffer vec4 position[]; vec4 velocity[]; ; uniform float deltaTime;
