Hi Martin, Hi Jesse, last week I've spent most of the time by fixing the bugs in my code. I've wrote a test for checking that source points fits to target points after transformation and it took my some time before I get expected results. One thing that makes my happy was experiments with larger datasets. Transformation of 80MB tiff (using approximately 20 MappedPositions that generated grid 500*500 ) takes just few seconds!
I've also disjoint the WarpGridBuilder and the calculation of WarpGrid by IDW interpolation into the abstract class WarpGridBuilder and IDWGridBuilder so all is prepared for another algorithm. I've also added general method for generating inverse transformation. Yesterday I've started to study the TPS algorithm – it looks very interesting but also quit complicated (when I'll want to implement some optimized algorithm). Finally few questions: It seems to me quit usable to add methods to MappedPosition that returns me the differences in both dimensions. Would you mind if I commit this minor change to trunk? In my demo I'm using raster file form my machine. Is there a way how to use some files from repo so that it will works right after checkout and mvn install? (I guess that committing another raster to repo is not best idea). Thanks in advance. Regards, Jan. P.S. I've wrote an abstract to FOSS4G about GSoC – hope that it will be accepted :) ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
