changes made to the deformation and reformation

for the past week i have been working on getting my deformation and reformation to real more realistically at the start of the week i was able to get the reformation working the way it should without took much hassle. only a few values used in the program needed to be changed to get the reformation working more realitsically

the defomration though caused alot of troubles. i originally intended to use the equations of an ellipsoid but this caused a problem with the deformation with the values throughout the whole surface being effected making the surface slanted and when made to deform cause the surface to stretch but not deform the way its suppose to do. With some thought the method has been changed to use the circle algorithm used to produce terrain. This works exceedingly well although it needs some teaks to get it working properly.

The ray intersecting has yet to be properly implemented and this needs to be seriously considered in the comming days and gotten to work as it is inputted.

update

right first update in a month. from the previous update the deformation has been placed in but hasn't been changed and reformation has been also placed in. this at first only worked as an inverse of the deformation but has later been changed to work with the bottom part of the reformation returning first and it slowly receding back to the start of the surface. ray/triangle intersection has also been implemented in but hasn't been properly introduced to work and run with the program.

I at the moment am working on getting the insecting traingles work to run and do what it suppose to on the program by allowing the user to select where the deformation taken place using a mouse. I am also looking into changing the deformation to a more realistic shape. this most likely would be a ellipsoid shape. After this i plan to work on the limitations of the deformation by making it dependent on the amount of kinetic eneergy placed on the surface and the tension of the surface working against the deformation of itself.
