2 comments for “Using Height Field Images for Creating Urban Grids”
This tutorial is incorrect and will not create correct models. This has nothing to do with paracloud, but with the conversion of a heightfield image to a rgb greyscale image. If it were as easy as this you could use the generated greyscale image as a displacement driver in any sophisticated 3d application then freeze the displaced geo. but you cannot do so as a multicoloured heightfield map once converted will not generate the deep blues as a low point. In the tutorial shows, it is shown as a high point in the resulting geometry.
We skipped a few processes - and will add it to the tutorial. If you use each color channel seperately you can create 3 heightfield images (for R,G and B channels) and then drive it based on each channel separately.
