Generating Ground from Measured Points and Adding Gradation Color/Contour Lines
[Measured Points of Ground]
Measured points have no overhang.
Points are changed to TINs. TIN program controls threshold angle/length of TIN MBR>in order not to generate unnecessary TINs.
A color gradation texture is mapped side of the ground.
NfDesign rendering function makes it possible to generate contour lines on the ground.
