====== Graphics ======


===== Core =====


==== XNAGame ====


This is the core implementation of IXNAGame. It provides the basic services for rendering with XNA/DirectX9 and handles mouse/keyboard input. It also provides an easy to use linerenderer and fps renderer.


[[:documentation:drawfps|DrawFPS]] renders fps. This will be capped to 60 unless [[:documentation:isfixedtimestep|IsFixedTimestep]] is set to false. Currently, vertical sync is disabled in XNAGame to enable a more interesting fps.


==== LineManager3D ====


This is used by the XNAGame to render lines, or boxes, triangles, … as lines. You add the lines every frame; add the end of the frame all the lines are removed.


===== Helper classes =====


==== LineManager3DLines ====


This class can be used to store lines for rendering with the LineManager3D. You can add lines to this object, and render them each frame without having to re-add them all like in the LineManager3D


==== AverageFPSCalculater ====


This class simply calculates the average frame length from framelenghts passed to it. It then holds a property that contains the FPS


==== ColladaShader (obsolete?) ====


This is a basic shader implementation for rendering textured/colored/normalmapped meshes. Supports vertex colored rendering, textured rendering and normal mapped rendering


==== BasicShader ====


This is a basic shader class for a shader that holds a world/view/proj matrix.  It provides functionality to compile a shader from an fx file. Note that this class does not hold an fx file, one must be provided.


===== Meshes =====


Note: Currently, these meshes have a reasonable common implementation. If more are added, inheritance or an adapter should be considered.


==== BoxMesh (obsolete?) ====


This is a helper class for simply rendering a box with given bounds and worldmatrix.  This class uses the [[:documentation:colladashader|ColladaShader]] for rendering. Supports raytracing


==== SphereMesh (obsolete?) ====


This is a helper class for simply rendering a sphere with given radius and worldmatrix. TODO: implement raytracing functionality
