Abstract

Implementations of dynamic shape approximation are described. In one technique described herein, a feature of interest in a first coordinate reference system is accessed and at least a portion of the feature is identified and converted to a second coordinate reference system. In one implementation, the size of the portion is chosen such that the portion can be represented in the second coordinate reference system with an acceptable amount of error.

Claims

1. A method of processing data from a location described by a coordinate reference system comprising:

accessing a feature of interest in a first coordinate reference system;

identifying at least a portion of the feature of interest; and

converting the at least a portion of the feature of interest using dynamic linearization into a second coordinate reference system.

2. The method of claim 1, wherein accessing includes receiving user instructions regarding the feature of interest.

3. The method of claim 1, wherein identifying includes limiting a size of the at least a portion of the feature of interest to a size which will result in a conversion error at or below an acceptable level when the at least a portion of the feature of interest is converted from the first coordinate reference system to the second coordinate reference system.

4. The method of claim 3, wherein limiting includes choosing a size of the portion of the feature of interest such that the conversion error will not be visible given a resolution of a monitor on which the portion of the feature of interest will be displayed.

5. The method of claim 3, wherein limiting includes choosing a size of the portion of the feature of interest such that the conversion error will be less than a preset value.

6. The method of claim 1, wherein the method is performed dynamically as a user views the feature.

7. The method of claim 1, further including:

caching one or more data points associated with the at least a portion of the feature of interest converted into terms of the second coordinate reference system, such that the one or more data points can be later accessed.

8. A computer-readable medium having a set of computer-readable instructions residing thereon that, when executed, direct a processor to initiate acts comprising:

dynamically representing a portion of a feature of interest stored in a reservoir model in a first coordinate reference system in terms of a second coordinate reference system;

wherein the portion is determined based on an acceptable conversion error.

9. The computer-readable medium of claim 8 having a set of computer-readable instructions that, when executed, perform acts further comprising receiving a user input indicating the feature of interest.

10. The computer-readable medium of claim 9 having a set of computer-readable instructions that, when executed, perform acts further comprising:

determining the portion, such that conversion error in representing the portion will not be discernable by a human eye given a resolution of a monitor being employed to view the portion.

11. The computer-readable medium of claim 10 having a set of computer-readable instructions that, when executed, perform acts further comprising:

receiving a user generated instruction to alter the resolution of the monitor to a new resolution; and

selecting a new portion of the feature of interest, which can be represented as large as possible in terms of the second coordinate reference system without conversion error being discernable by a human eye given the new resolution of the monitor.

12. The computer-readable medium of claim 8 having a set of computer-readable instructions that, when executed, perform acts further comprising allowing a user to set the acceptable conversion error.

13. The computer-readable medium of claim 8 having a set of computer-readable instructions that, when executed, perform acts further comprising dynamically linearizing the portion of the feature of interest.

14. The computer-readable medium of claim 13 having a set of computer-readable instructions that, when executed, perform acts further comprising selecting linear lengths to be used to form a linearized portion of the feature of interest, such that each length has an acceptable conversion error when represented in terms of the second coordinate reference system.

15. The computer-readable medium of claim 8 having a set of computer-readable instructions that, when executed, perform acts further comprising caching endpoints of the linear lengths expressed in terms of the second coordinate reference system.

16. A method comprising:

accessing a request to access a section of interest stored in a model in a first coordinate reference system;

linearly representing at least a portion of the section of interest in terms of a second coordinate reference system; and

determining a size of the at least a portion of the section of interest based on an acceptable conversion error.

17. The method of claim 16, wherein accessing includes receiving a user generated request.

18. The method of claim 16, wherein linearly representing includes determining a size of the at least a portion of the section, such that a conversion error in representing the at least a portion is at or below an acceptable error.

19. The method of claim 18, wherein determining includes ascertaining a size at which conversion error is not discernable by a human eye given a resolution of a monitor being employed to view the at least a portion of the section.

20. The method of claim 16, wherein determining includes representing the entire section as a series of linear lines such that the entire section can be displayed in the second coordinate reference system without exceeding the acceptable conversion error.
