                    <p>
                      As my final degree's thesis I researched how to simulate a laparoscopy,
                      a medical procedure that is used to examine the abdominal area and remove tumors
                      with the use of forceps, scissors and a camera, using the VR set up already done.<br>
                      The objective was to create a first approach of a simulation of this kind
                      of medical procedure since the real operation is also done through a screen
                      and a realistic enough simulation could be used to practice.

                      The main focus of this project, asie from the VR aspect, was to model a
                      physiscs problem: how to simulate a
                      <span style="font-weight: bolder; font-size: medium; color: rgb(179, 73, 84)">
                        soft body object </span>
                      that represents organs.<br>
                      To do that I used Unity components like
                      <span style="font-weight: bolder; font-size: medium; color: rgb(179, 73, 84)">
                        spring joints</span>
                      that stretch and contaract when applying force to them to modify the initial mesh
                      by subdividing the object into small particles that are connected with these joints.<br>
                      The other physics problem to model was how the soft body objects interact with the
                      laparoscopic tools: how the "organs" are cut and pinched by these tools. The tools als had a
                      script to animate their movement in a realistic way. More details of this project can be found in this
