opengl-graal-examples

Demo of a rotating Utah teapot, built using OpenGL and GraalVM.

It's written completely in Java and uses GraalVM's native-image utility to compile down to a stand-alone native binary as small as 6mb. This binary does not require any Java runtime and launches as fast as counterparts written in C/C++. The source code is almost a direct translation of examples from Rosetta Code.

Building

You'll need JDK 11 or higher installed. This project uses Gradle, and it should automatically download the GraalVM distribution for you. Use the following command to build:

./gradlew nativeImage

GraalVM would take a while to do all the hard work. After the compilation is over, you can launch the executable using Gradle:

./gradlew runNative

or run it directly as:

./build/graal/glExample

It works perfectly on 64-bit Linux and should work on other systems as well, though you might need to make minor modifications to the bindings.
