Reverse Time Migration

Title: “Reverse Time Migration”

This work of art is based on my diploma work in option to the title of Geophysical Engineer. Surely when reading this they would think… what relationship can exist between Earth Sciences and generative art??? So here is the explanation:

This work seeks to artistically represent an algorithm used in Geophysics to obtain 2D images of the subsoil. I will make the explanation as simple as possible :) . The reverse time migration (RTM from now on) carries out a propagation of the wave field forward in time and at the end a backward propagation is carried out, that is, you temporarily retrace your steps. This is really just one part of the algorithm as it is too robust to fully render, but I remember it was the most fun part because of the images I got. Therefore, in this artistic version, the movement of waves forwards and backwards in time is parodied.

Based on the above, RTM (artistic version) has several ✳️PARAMETERS✳️ that you can modify to obtain unique results, as follows:

✅ [ seed ] : it is the classic seed present in all the projects without parameters, modify it and you will obtain new distributions of the objects conditioned by it randomly.

✅ [ Theme ] : select between two themes for the image:
-full wave: shows the trace of the wave when moving forward
-front wave: only shows the front of the wave erasing the trace

✅ [ Number-waves ]: controls the number of “waves” to be drawn

✅ [ Wave-weight ]: controls the thickness of the wave edge

✅ [ Initial-size ]: controls the initial size with which the waves will begin to form at the instant t=0

✅ [ Expansion time]: it is not an average of time, it is just a counter that controls how long the expansion lasts and therefore the contraction of the waves

✅ [ Border-width ]: controls the width of the border of the full image frame

✅ [ Border-color]: controls the color of the image frame

✅ [ Background-color] : controls the background color of the image

✅ [ Use palettes ] : if this box is active, the colors will automatically be governed by the palette you select. Therefore, all other parameters related to color will stop working. It has 54 color palettes formed with every intention of achieving a good harmony :)
