An apparatus for controlling the visualization of a three dimensional object displayed in virtual reality, augmented reality, or other virtual space comprising a means of determining the requisite change in visualization, and a means for updating the three dimensional object.
The process may be performed automatically by a system or may be guided interactively by an operator.
Applications include, but are not limited to, virtual reality, augmented reality and three dimensional printing.
A visualization in virtual space can be controlled in a variety of different ways under the invention.
In one embodiment of the invention, the model display depth is controlled automatically or by user interaction to display parts of the model not initially visible.
The model can either be densely packed (including all information) or a “hollow” model consisting of perimeter information only to a limited depth.
This perimeter information can be calculated using negative space exploration.
As the user indicates a portion of the model they would like to see deeper, the outer sections of the model are hidden and the underlying data is displayed.
Negative space exploration is don e by selecting an empty starting point at the edge of the model's cartesian space, frequently at (0, 0, 0) [x, y, z coordinate].
Each adjacent coordinate is added to an exploration list provided that the coordinate does not satisfy the search parameter, for example a minimum colour value threshold.
When a point is met which satisfied the search parameter, it is added to the objects perimeter array, and in the case of depths greater than one coordinate the depth counter for the angle is decremented.
Coordinates satisfying the search parameter are not added to the search list.
