JGLOOm stands for Java openGL: Object Oriented (man!) it is Java library that wraps the functionality of the OpenGL API in a more object-oriented package. It puts OpenGL objects into Java interfaces, and their functions into static factories / container utils, allowing for code to be reactive to the user’s OpenGL version/platform dependency. It also provides users higher-level utilities like tracker objects that follow OpenGL values (like a texture parameter) around, reducing API calls.

Repository for loading file formats into those objects (no work has been done here yet)

Currently the library is in pre-production and we’re working on the standard for it. Here’s some stuff we have done though:

GLBuffers - Interface and LWJGL Containers
GLTextures - Interface and LWJGL Containers
GLFrameBuffers - Interface and LWJGL Containers
GLRenderBuffers - Interface and LWJGL Containers
GLSLShaders - Interface and LWJGL Containers
GLSLPrograms - Interface and LWJGL Containers

LWJGL Specific:
GLFWWindows - Interface and LWJGL Containers
GLFWMonitors - Interface and LWJGL Containers

Here’s how an object looks in our library

public interface GLBuffer {
    /** @return The identifier for the buffer object */
    int getBuffer();
}

The focus of this library was not just the higher-level manipulation of OpenGL objects, but also loading popular file formats such as these:
Image formats

  • JPEG
  • PNG
  • TIFF
  • GIF
  • BMP

Model formats (Planned)

  • MD5 - Animations and all
  • OBJ
  • FBX
  • Collada - We intend to use JCollada
  • Blend - In the very far future, as a tech demo (it would be very hard)

Behold the power of the higher level!

Lambdas:

public GLBuffer getMyBuffer(){
    int buffer = GL15.glGenBuffers(); 
    return () -> buffer;
}

Texture Loading into WebGL, JOGL, and LWJGL all at once!

// GLFTextureImage2D is a group of functions that represent an OpenGL texture that supports Image2D.
// It's class extends from GLFTexture, with defines basic functions like bind and delete
// Containers implement these functions as a sign of what their library supports (some libraries might not support GLFTextureImage3D for example)
TextureLoader.load(GLFTextureImage2D, InputStream)



// LWJGL's textures, as well as WebGL, JOGL and everything else supports Image2D, so their supported in their containers:
GLTextureContainer lwjglTexture = new GLTextureContainer(LWJGLTextures.createTexture())
JGLTextureContainer joglTexture = new JGLTextureContainer(JOGLTextures.createTexture())
WGLTextureContainer webTexture = new WGLTextureContainer(WGLTextures.createTexture())



TextureLoader.load(lwjglTexture, new FileInputStream(...));
TextureLoader.load(joglTexture, new FileInputStream(...));
TextureLoader.load(lwebTexture, new FileInputStream(...));

What we’re working on now is just that but with 3D models :persecutioncomplex:

More examples to come.
