Relief Mapping experiments

The 3d modelling I wish to use for this project relies on the process of using relief mapping to read 2d images and turn them into 3D virtual constructs. Cinema 4D does this very efficiently and renders them fairly quickly and accurately.

The first experiment I carried out was to model the front elevation with accuracy using the depth measurements taken on site and from photographs.

Relief mapping works by reading an images levels of brightness and converting them into positions of depth.

White= 100% brightness= furthest forward on the relief map Black= 0% brightness= furthest back on the relief map

Any levels in between get placed accordingly.

The element of the facade nearest you is the metal vertical cladding running up the building (equals white 100%).

The element furthest from you is the glazing (equals black 0%).

The distance between the two is 1500mm, setting the relief map to this then allows me to calculate the levels required for accurately positioning all other elements.

The concrete slab needs a level of brightness = 35%

These levels are applied to the CAD drawing in photoshop in greyscale. Below is the initial relief map for the top eight floors.



Here is the new relief map of 1 floor only and the resulting C4D facade.
