gles3jni

gles3jni is an Android C++ sample that demonstrates how to use OpenGL ES 3.0 from JNI/native code.

The OpenGL ES 3.0 rendering path uses a few new features compared to the OpenGL ES 2.0 path:

  • Instanced rendering and vertex attribute divisor to reduce the number of draw calls and uniform changes.
  • Vertex array objects to reduce the number of calls required to set up vertex attribute state on each frame.
  • Explicit assignment of attribute locations, eliminating the need to query assignments.

This sample uses the new Android Studio CMake plugin with C++ support.

Pre-requisites

  • Android Studio 1.3+ with NDK bundle.
