Extra Dimensions in Visualisations
October 20, 2011 § Leave a comment
Visualisations can be augmented with more data with additional dimensions.
Extrusion, for example, can be used to visualise data in the context of its surroundings.
2.5 Dimensional visualisations can be equated to a 2d map with each point set to a specific point (height) on the third dimension. As each x-y co-ordinate can only have one z-co-ordinate, features like caves can not be represented. 3 dimensions do not have this limitation.
It is interesting to note that it is quite standard to exaggerate the vertical axis of a 2.5 dimensional visualisation by 1.5x or 2.0 times. This is because we feel this represents the map a lot more as we are accustomed to seeing elevations from the ground level at close distances.
Looking at an Angkhor 3d visualised animation as a case study, it was observed that artistic input was required (there are much too many variables for a short project to cover everything realistically), with 3ds-max imported 3d models (such as elephants). The existence of such visualisations for simulations help evaluate multiple dimensions of data (and similarly, has a broad feedback loop).
3D visualisations (as seen in the case study of RegentVille), can provide very short animations that are a very good contextual overview and can summarise 15-20 years of architectural information of a site.
