rlm@73 9 * Intro
rlm@73 10 So far, I've made the following senses --
rlm@73 11 - Vision
rlm@73 12 - Hearing
rlm@73 13 - Touch
rlm@73 14 - Proprioception
rlm@73 15
rlm@73 16 And one effector:
rlm@73 17 - Movement
rlm@73 18
rlm@73 19 However, the code so far has only enabled these senses, but has not
rlm@73 20 actually implemented them. For example, there is still a lot of work
rlm@73 21 to be done for vision. I need to be able to create an /eyeball/ in
rlm@73 22 simulation that can be moved around and see the world from different
rlm@73 23 angles. I also need to determine weather to use log-polar or cartesian
rlm@73 24 for the visual input, and I need to determine how/wether to
rlm@73 25 disceritise the visual input.
rlm@73 26
rlm@73 27 I also want to be able to visualize both the sensors and the
rlm@73 28 effectors in pretty pictures. This semi-retarted creature will by my
rlm@73 29 first attempt at bringing everything together.
rlm@73 30
rlm@73 31 * The creature's body
rlm@73 32
rlm@73 33 Still going to do an eve-like body in blender, but due to problems
rlm@73 34 importing the joints, etc into jMonkeyEngine3, I',m going to do all
rlm@73 35 the connecting here in clojure code, using the names of the individual
rlm@73 36 components and trial and error. Later, I'll maybe make some sort of
rlm@73 37 creature-building modifications to blender that support whatever
rlm@73 38 discreitized senses I'm going to make.
