Detailed Description

Display overlayed image slices in 2D.

The functionality is similar to SlicerRepSW, but the actual slicing is performed by loading the image into the GPU as a 3D texture and slicing it there, using the GPU.

Several images are sliced simultaneously, and are overlayed using the alpha transfer function (it is assumed to be a step function).

The Texture3DSlicerRep draws several image slices in an overlay. Opacity and LLR are used to draw several images on top of each other. Despite its name is this a 2D Rep (it is drawn in a plane).

The Texture3DSlicerRep class itself does very little real work: It inherits from RepImpl and Rep, thus it can be added to a View. The drawing functionality is embedded in Texture3DSlicerProxy, while the slicer functionality is embedded in SliceProxy.

SliceProxy determines the slice matrix and viewport from a Tool and the slice definition (fex Axial, Sagittal, etc.). It uses a SliceComputer to do the math. Texture3DSlicerProxy is a base class with default dummy behaviour. This is solely a hack to get the code to compile on Windows. The real behaviour lie in Texture3DSlicerProxyImpl. It assembles images and a slice definition, which is sent to the TextureSlicePainter to be renderered. Most of the actual OpenGL code in embedded inside TextureSlicePainter.
