takes 1 sec to compile any changes I need.
lucky I still had it.
code::blocks is tits.

http://news.povray.org/povray.binaries.utilities/thread/%3Cweb.5dddc62da775b16c9da690110%40news.povray.org%3E/


next it should accept command line params, batch file 50 dems.
and write output text, to height_field.pov

 still thinking on deltaY ... 3 is 1x1 degree - code says.
30 is 10x10 ? so DeltaY might be 30 / 360? ... not sure what deltaY is doing.
but its works now. for Shasta I did ...

-min_elev(different each one.)

ok - not that hard.
// start DEMPOV bigbend.dem bigbend.tga 0 0 15.000000 -442.000000 0.000000
or if you dont know bias, it's auto set, just leave it out
// start DEMPOV bigbend.dem bigbend.tga 0 0 15 0

and now writes this file:

// POV Height_field Example v. 1.0
height_field {
  // spatialResolution 30.000000 30.000000 1.000000
  // verticalScale 15.000000
  // width height 468 356
  tga "bigbend.tga"
  smooth
  translate <-0.5,-0.5,-0.5>
  scale <468,468,468>
}
  // start DEMPOV bigbend.dem bigbend.tga 0 0 15.000000 -442.000000 0.000000

DEMPOV bollibokkamtn.dem bollibokkamtn.tga 0 0 15 0
DEMPOV burney.dem burney.tga 0 0 15 0
DEMPOV chalkmtn.dem chalkmtn.tga 0 0 15 0
DEMPOV goosegap.dem goosegap.tga 0 0 15 0
DEMPOV roaringcreek.dem roaringcreek.tga 0 0 15 0
processing time maybe 1.5 secs

now I can read all the dem headers in a folder and write the batch file.
could read long lat and sort, but, sheesh maybe not today.

next 5
