This binary does not require any Java runtime and 11 | launches as fast as counterparts written in C/C++. The source 12 | code is almost a direct translation of examples from 13 | [Rosetta Code](https://rosettacode.org/wiki/OpenGL/Utah_Teapot). 14 | 15 | ## Building 16 | You'll need JDK 11 or higher installed. This project uses Gradle, 17 | and it should automatically download the GraalVM distribution for 18 | you. Use the following command to build: 19 | ```shell script 20 | ./gradlew nativeImage 21 | ``` 22 | 23 | GraalVM would take a while to do all the hard work. After the 24 | compilation is over, you can launch the executable using Gradle: 25 | ```shell script 26 | ./gradlew runNative 27 | ``` 28 | or run it directly as: 29 | ```shell script 30 | ./build/graal/glExample 31 | ``` 32 | 33 | It works perfectly on 64-bit Linux and should work on other systems 34 | as well, though you might need to make minor modifications to the 35 | bindings. 36 | -------------------------------------------------------------------------------- /src/main/java/in/praj/glexamples/GLUT.java: -------------------------------------------------------------------------------- 1 | package in.praj.glexamples;
