Software Design3.4. Using Virtual Arrays as a Filterof green points along the side of the shuttle in one principle direction. A selection ofred points of the external tank equally spaced as in the original image. A wide selectionof blue points to visualize the solid rocket booster and its dense parts of the grid.Figure 3.8: CashFlow: Space shuttle visualized with PointRender node and a selection of the data.When handling a virtual array several strategies are useful which are:• Single Block Arraywhere one contiguous block in the real array is the virtual array.• Multiple Block Arrayusing several contiguous blocks in the real array to form the virtual array. Eachblock consists of a certain number of successive fields and a number of successiveskipped fields.• Random Access Arraycombining random fields of the real array to build the virtual array.The three types of virtual arrays will be discussed in detail in section 3.7.1 on page 54For ease of use iterators are also introduced to access the virtual array.48
