It is an industry standard API for writing 3D Graphics applications. Rendering is the process of creating an image from a 2D or 3D model. It interacts with Graphical Processing Unit (GPU) for achieving speedy and It has bindings in several languages such as C++, Python, etc With OpenGL, you can create complicated 3D shapes using very basic primitives such as points, lines, polygons, bitmaps, and images. OpenGL stands for Open Graphics Library, which is a collection of commands to create 2D and 3D graphics. JOGL functions on various operating systems such as Windows, Solaris, Mac OS X, and Linux (on x86). Later, it was adopted by the gaming group at Sun Microsystems, and now it is maintained by Java on Graphics Audio and Processing (JOGAMP). JOGL is an open-source library initially developed by former MIT graduate students Ken Russell and Chris Kline. It is a wrapper library, which can access OpenGL API, and it is designed to create 2D and 3D graphics applications coded in Java. Java binding for Open GL (JOGL) is the recent binding for OpenGL graphics API in Java. If there is something you dont understand about my issue please just ask.This chapter introduces OpenGL, its functions, the OpenGL bindings in java (GL4java, LWJGL, JOGL), and the advantages of JOGL over other OpenGL bindings. Im having a bit of problems as you can see. I REALLY want to use Collada and animate it. Thank you for reading and I hope someone can help me out here. However Im not sure if that would even provide the correct values. I would have to put the vertex into a matrix and multiply the two matrixs using the matrix multiplication method supplied by LWJGL. With that library you cant just multiply a vertex (Vector3f/3 Values) by a matrix (Matrix4f/4x4/16 values). I am using Java with the LWJGL library which is primarily OpenGL. With all of the tutorials I have looked through I see C++ code and thats it. I have done that and messed with it a bit, the closest i get to the first frame of the animation is using “VERTEX * JOINTMATRIX”. They all give around the same equation which is “((VERTEX * BINDSHAPEMATRIX) * INVERSEBINDPOSE * JOINTMATRIX) * JOINTWEIGHT”. I have been through numerous websites with collada tutorials on skinning. I am currently having difficulties with the skinning process. Loaded all data for the model/skeleton/animation.
