Abstract
| |
It has long been recognized that transfer function setup for Direct Volume Rendering (DVR) is crucial to its
usability. However, the task of finding an appropriate transfer function is complex and time-consuming even for
experts. Thus, in many practical applications simpler techniques which do not rely on complex transfer functions
are employed. One common example is Maximum Intensity Projection (MIP) which depicts the maximum value
along each viewing ray. In this paper, we introduce Maximum Intensity Difference Accumulation (MIDA), a new
approach which combines the advantages of DVR and MIP. Like MIP, MIDA exploits common data characteristics
and hence does not require complex transfer functions to generate good visualization results. It does, however,
feature occlusion and shape cues similar to DVR. Furthermore, we show that MIDA – in addition to being a useful
technique in its own right – can be used to smoothly transition between DVR and MIP in an intuitive manner.
MIDA can be easily implemented using volume raycasting and achieves real-time performance on current graphics
hardware.
