The Volume Viewer is the main module of the system. It displays 3D data by a technique called "Direct Volume Rendering". The whole volume data is displayed directly without further conversion of the geometry like surface construction algorithms (marching cubes). The result is a natural and clear representation of the volume data. The volume object can be rotated and scaled in real-time by the left and right mouse button. The volume data can be processed by several functions (see Functions page for more information): - a surrounding frame cube can be displayed, - the frames per second can be displayed, - a Maximum Intensity Projection (MIP) can be enabled, - the resolution of the volume texture can be choosen between low, medium and high resolution, - the clipping volume can be adjusted by the position of the left, right, rear, front, lower and upper side, - all 3 angles of the clipping volume can be free adjusted in order to tilt it, - level / window settings, - different color lookup tables, - the transparency function can be adjusted just like the level / window settings, - a lighting function can be enabled, which produces more vivid views (ambient and diffuse parts can be set seperatly), - the camera can be turn in x-, y- and z-axis and can be rotated for an animation sequence. - a stereoscopic view can be turned on for anaglyph views with support for red/blue, blue/red, green/red and red/green glasses.
