Is there any way to generate reversed taper geometry? In other words: I'd like to generate the geometry you can see in the following picture just by using displacement modifiers or by using nodes:
Q: Is something like this possible by using displacement? The purpose of me thinking that this is nearly impossible is because if having a larger displacement on top, how am I supposed to depict a tapering gradient bellow it visually on a map? You can not show a dim gradient bellow a bright surface on a displacement map right?
Note: This question is not specifically about cones, it is about any type of displacement where I have a bigger surface on top of a smaller surface.
For better illustration consider a plane , Subdivide it 100 times and switch to cycles rendered mode with Displacement type set to Displacement and bump. The if i create the following Node tree , i can get the following result. The node tree is finding the Length of the origin and using a color ramp to manipulate the falloff of the resulting spherical gradient and passing through a displacement map to get the final result , but how can i taper at the bottom and have a bigger surface at the top?
