Abstract

Obtaining physical model data for CAD model generation with a process that includes: receiving a first acceleration-based path data set including acceleration data for an accelerometer device as it was traced over a first path along the surface of a physical object, converting the first acceleration-based path data set to a first position-based data set including position data for the accelerometer as it was traced over the first path along the surface of the physical object, and generating a three dimensional object model data set based, at least in part on the position data of the first position-based data set.

First claim

What is claimed is:

1 . A method for obtaining physical model data for CAD model generation, the method comprising:
receiving a first acceleration-based path data set including acceleration data for an accelerometer device as it was traced over a first path along the surface of a physical object; converting the first acceleration-based path data set to a first position-based data set including position data for the accelerometer as it was traced over the first path along the surface of the physical object; and generating a three dimensional object model data set based, at least in part on the position data of the first position-based data set.

2 . The method of claim 1 further comprising:
tracing the accelerometer device over the first path along the surface of the physical object.

3 . The method of claim 2 wherein tracing is performed by a trackball in electronic communication with the accelerometer device.

4 . The method of claim 1 wherein the first acceleration-based path data set further comprises reference position data.

5 . The method of claim 4 wherein the reference position data comprises a start point of the first path.

6 . The method of claim 1 wherein the accelerometer device is a smart phone.

7 . A computer program product for obtaining physical model data for CAD model generation, the computer program product comprising software stored on a software storage device, the software comprising:
first program instructions programmed to receive a first acceleration-based path data set including acceleration data for an accelerometer device as it was traced over a first path along the surface of a physical object; second program instructions programmed to convert the first acceleration-based path data set to a first position-based data set including position data for the accelerometer as it was traced over the first path along the surface of the physical object; and third program instructions programmed to generate a three dimensional object model data set based, at least in part on the position data of the first position-based data set; wherein: the software is stored on a software storage device in a manner less transitory than a signal in transit.

8 . The computer program product of claim 7 further comprising:
fourth program instructions programmed to, responsive to an acceleration data input from the accelerometer device, generate the first acceleration-based path data set.

9 . The computer program product of claim 8 wherein the acceleration data input is communicated by a trackball in electronic communication with the accelerometer device.

10 . The computer program product of claim 7 wherein the first acceleration-based path data set further comprises reference position data.

11 . The computer program product of claim 10 wherein the reference position data comprises a start point of the first path.

12 . The computer program product of claim 7 wherein the accelerometer device is a smart phone.

13 . A computer system for obtaining physical model data for CAD model generation, the computer system comprising:
a processor(s) set; and a software storage device; wherein: the processor set is structured, located, connected and/or programmed to run software stored on the software storage device; and the software comprises:
first program instructions programmed to receive a first acceleration-based path data set including acceleration data for an accelerometer device as it was traced over a first path along the surface of a physical object;
second program instructions programmed to convert the first acceleration-based path data set to a first position-based data set including position data for the accelerometer as it was traced over the first path along the surface of the physical object; and
third program instructions programmed to generate a three dimensional object model data set based, at least in part on the position data of the first position-based data set.

14 . The computer system of claim 13 wherein the software further comprises:
fourth program instructions programmed to, responsive to an acceleration data input from the accelerometer device, generate the first acceleration-based path data set.

15 . The computer system of claim 14 wherein the acceleration data input is communicated by a trackball in electronic communication with the accelerometer device.

16 . The computer system of claim 13 wherein the first acceleration-based path data set further comprises reference position data.

17 . The computer system of claim 16 wherein the reference position data comprises a start point of the first path.

18 . The computer system of claim 13 wherein the accelerometer device is a smart phone.
