New 3D Biomorphs for LifeDrop

Finally, we have choosen a new 3D design approach for the LifeDrop virtual creatures. Each biomorph is composed of a set of 3D building blocks: segments, head, tail, antenna, eyes, etc. The DNA of a creature includes a structural template thatcan be evolved through mutation, cross-over and natural selection. The set of possible creatures is very big even if not really infinite. As in the previous version of LifeDrop, there are three basic types of creatures: (1) predators haunting any other creatures, and (2) preys eating (3) weeds in the virtual water drop. The software is under development in Java and a realtime 3D engine that will enable to render biomorphs with a higher level of realism compared to the previous versions that were quite minimalistic from this point of view (see preview images). The 3D engine will manage two models for each creature: a "low-polygons" model for the rendering of the ecosystem as a whole, and a "high-polygons" model in a dedicated "magnifying glass" window.

Another goal of this new implementation is to reduce the number of parameters for experiments. This is important in order to have a more precise study of evolution dynamics. With two many parameters, it is quite difficult to analyze which ones are really meaningfull and those which are useless and only add noise in experiments. LifeDrop version 4 is now an on-going project...
