Hi Group,
Please notice --> https://www.dropbox.com/s/79gqsywr66j3ftp/issue.PNG?dl=0
Context:
1).Both DSM and texture image's arrays were obtained by reading tiff files (yup I've rotated the tiff image accordingly[using ROTATE()], no issues with that)
2).Also tried scaling the texture image using BYTSCL (no use!)
3) I Did play with Z range
I require :
* A 3D surface that looks like the left image(refer URL)
* An output of 300X300 is sufficient !! The large sized, high resolution graphic is very slow. Would someone happen to know how to bring down the resolution
Please let me know your thoughts on this.
Regards,
Puneeth

Hi,
I think your experiencing an error that I've seen, but I couldn't pin down. It appears as if the left side of the surface window is obstructed by something white. If you move your surface around, you should be able to move it behind this white region.
In my case this happens even with the standard example from surface:
; Read in a 2D array of surface heights
dir = FILEPATH('',SUBDIR=['examples', 'data'])
z = READ_BINARY(dir+'elevbin.dat', DATA_DIMS=[64,64])
; Read in a texture image to overlay
READ_JPEG, dir+'elev_t.jpg', image
s = SURFACE(z, TEXTURE_IMAGE=image, YSTYLE=1)
If I try this, I get a surface cut along the middle vertical line. The right side is visible and the left side is hidden...
If I move the surface to the right, I can view all of it.
I had this error come and go, and I have no idea at the moment how to make it go...
But at least you could try to make a rectangular window, something like:
w = window(dimensions=[1200,400])
then plot with
s = SURFACE(z, TEXTURE_IMAGE=image, YSTYLE=1, current=w)
and then move the surface with this command:
s.position = [0.75,0.5]
That should make it visible...
It's not a solution, but I can't come up with nothing better at the moment. Please let me know if you have a "real" solution.
Cheers,
Helder
