Abstract
The present invention relates to a method of generating implicit terrain data and an electronic apparatus for performing the method, and more particularly to a method of generating implicit terrain data and an electronic apparatus which are capable of minimizing a size of data while maintaining geographical quality of original terrain data.
Claims20
A method of generating implicit terrain data, the method comprising:
- constructing implicit terrain data from original terrain data;
- performing lossless compression on the implicit terrain data;
- reconstructing the losslessly compressed implicit terrain data;
- and
- performing lossy compression on the reconstructed implicit terrain data.
2 more elements
An electronic apparatus which generates implicit terrain data, the electronic apparatus comprising:
- a processor,
- wherein the processor conducts
- generating implicit terrain data using a height value of nodes forming original terrain data;
- performing lossless compression using nodes of the implicit terrain data;
- reconstructing the losslessly compressed implicit terrain data;
- and
- performing lossy compression on the reconstructed implicit terrain data using the original terrain data and the implicit terrain data.
