After watching a turorial recently that used the displacement modifier extensively, I thought I would produce an image that let me understand how much displacement occurred when a grey-scale image produced in GIMP was applied to a plane. GIMP allows the 'Value' parameter to be between 0-100.
Having not used the displacement modifier much I found producing this image useful, I hope others do too.
Thanks for the acknowledgements.
Note the mesh is just a highly subdivided plane. All the differences in height including the numbers, is done through applying a displacement texture.
The plane does have a slight Voronoi Texture bump map applied to give it some roughness.
Thank you for the reference.
Thanks
