A lot have been improved in the 3D Analyst 10 including the ability to export large scenes as large 2D images. However, some problems still exist one of which is:
When I export a scene that contains a very large TIN the resulting image appears to have some triangles shaded darker which causes a "spotty" appearance. It's almost as if some "faces - triangles" were shaded incorrectly, or reversed?
My current graphics card is NVIDIA Quadro 4000. (Used to have the NVIDIA Quadro FX 1700 which caused similar issues with the 9.3 version of 3D Analyst) I should also mention that it does not matter what type of image i export, compressed or not the result it more less the same.
Does anyone have any ideas as to how to rectify this?
It seems that this is only happening when the TIN is exaggerated, in this case 5x
If I drape imagery over the terrain and turn the IN off, there are no issues. This problem pertains only to the display of a TIN.
