  Heightfield problem (Message 1 to 2 of 2)  
From: gemelli david
Subject: Heightfield problem

When I try rendering the scene below using slow.ini, there's a CW error.

When the upper border of the heightfield is reached, POV crashes.

I tried a lot of things but I didn't manage to correct it. Could someone

explain me what's wrong or what I have to do to render my scene
correctly ?
(now, I put the camera lower so the border is out of the view)

    Thanks.

// the scene
#include "colors.inc"

#declare Camera_M =
camera {
     orthographic

     location <0,5,0>
     sky <0,0,1>
     direction <0,-1,0>

     up <0,0,.5>
     right <.5,0,0>
}

camera {
     Camera_M
     translate <.25,0,1.80>        // when <.25,0,1.25> no error
}

light_source {
     <-10,10,-10>
     color White
}

#declare Paysage =
height_field {
     gif "ground.hgt"
     smooth
     texture {
          pigment {
               image_map{
                    gif "ground.map"
                    interpolate 2
               }
          }
          finish {
               ambient 0.3
               crand 0.2
          }
          rotate x*90
     }
     scale<2,.1,2>
}

object {Paysage}
// end of the scene

// the CW.ERR file (useful ??)

Try a slight x or z axis offset yet?
That might do it.
'location <0.01,5,0.01>' and maybe even a 'look_at <0.01,0,0.01>'.
