The card may chop that down to something less precise from there, but it will have been as accurate as it's going to get at that point.Renansehttp://www.blogger.com/profile/15896461050886104953noreply@blogger.comtag:blogger.com,1999:blog-8790183.post-90418138983011386552008-12-30T01:49:00.000-06:002008-12-30T01:49:00.000-06:00Hi Renanse,<br><br>do you compute the transforms w...Hi Renanse,<BR/><BR/>do you compute the transforms with double precision on the video card? If yes, did you have a chance to test the precision of different cards? Is a java-fallback for computing transformations necessary?<BR/><BR/>Best regards,<BR/>IrrisorIrrisorhttp://www.blogger.com/profile/16829880893816767120noreply@blogger.com
