Package org.xjge.graphics

Class Graphics

java.lang.Object
org.xjge.graphics.Graphics
public final class Graphics
extends java.lang.Object
Component object that supplies implementing objects with the following:
  • A vertex buffer object - As a default buffer through which the implementing class may supply its vertex data to the graphics pipeline.
  • A index buffer object - To discourage data redundancy by specifying which vertices to reuse for the objects model mesh.
  • A vertex array object - For providing convenient access to the default vertex buffer in addition to any the implementation may define.

Implementing objects should define their vertex data and vertex attribute layouts in their constructors using LWJGLs memory utilities such as MemoryUtil or MemoryStack (the later of which only if the vertex data doesn't exceed the JVMs stack size). LWJGLs Assimp binding is also available in conjunction to the previously mentioned classes to load vertex data in the form of a 3D model.

  • Method Details

    • bindBuffers

      public void bindBuffers()
      Convenience method provided to bind the default buffers defined by this class. Implementing classes are expected to define vertex attribute layouts following this call in their constructors with methods like glVertexAttribPointer().

    • freeBuffers

      public void freeBuffers()
      Convenience method which frees the default buffer objects defined by this class. Additional buffers required by the implementing object will need to be freed individually. This method should be called in conjunction with MemoryUtil.memFree() if additional data was used during the implementing objects lifetime.
