Abstract

Claims (90)

1. A method comprising:

analyzing a data file representing a three dimensional object to automatically identify a plurality of views of interest based on at least one observable characteristic of the three dimensional object;

automatically eliminating views with an information content below a threshold; and

defining an access mechanism to permit the plurality of views to be accessed.

2. The method of claim 1 wherein defining comprises:

automatically creating an adjusted scale representation of each view of interest; and

associating the adjusted scale representation with an actuatable control.

3. The method of claim 1 further comprising:

rendering a representation of the three dimensional object from the data file; and

automatically translating the object to a corresponding view of interest responsive to an actuation of a control associated with a corresponding representation.

4. The method of claim 1 wherein the plurality of views includes all six orthogonal views.

5. The method of claim 1 wherein the information content is determined relative to other views.

6. The method of claim 1 further comprising:

automatically creating a sequence for presenting the plurality of views in a prescribed manner.

7. The method of claim 6 further comprising:

automatically presenting the sequence responsive to an event.

8. The method of claim 1 wherein the characteristic is one of:

shape of the object, texture map of the object, indicia of the object, local detail of the object, and color of the object.

9. The method of claim 1 further comprising:

displaying a representation of the three dimensional object in a viewing window; and

automatically providing a scale indicator that relates to an actual dimension of the three-dimensional object.

10. The method of claim 9 wherein the scale indicator is one of dimension lines, coordinates, a grid, and a reference object.

11. The method of claim 1 further comprising:

displaying a representation of the three dimensional object in a viewing window; and

automatically providing a color reference to allow for calibration of color of a display device.

12. The method of claim 1 further comprising:

displaying a representation of the three dimensional object in a viewing window; and

automatically selecting a display background based on at least one characteristic of the object.

at least one stock criterion;

at least one user-specified criterion; and

a combination of user specified and stock criteria.

20. The method of claim 18 wherein the definition includes at least one of:

geometrical shape of the object, surface texture of the object, indicia of the object, and local detail of the object.
