rlm@99 9 * objectives
rlm@103 10 - [X] get an overall bitmap-like image for touch
rlm@103 11 - [X] write code to visuliaze this bitmap
rlm@99 12 - [ ] directly change the UV-pixels to show touch sensor activation
rlm@99 13 - [ ] write an explination for why b&w bitmaps for senses is appropiate
rlm@99 14 - [ ] clean up touch code and write visulazation test
rlm@99 15 - [ ] do the same for eyes
rlm@99 16
rlm@73 17 * Intro
rlm@73 18 So far, I've made the following senses --
rlm@73 19 - Vision
rlm@73 20 - Hearing
rlm@73 21 - Touch
rlm@73 22 - Proprioception
rlm@73 23
rlm@73 24 And one effector:
rlm@73 25 - Movement
rlm@73 26
rlm@73 27 However, the code so far has only enabled these senses, but has not
rlm@73 28 actually implemented them. For example, there is still a lot of work
rlm@73 29 to be done for vision. I need to be able to create an /eyeball/ in
rlm@73 30 simulation that can be moved around and see the world from different
rlm@73 31 angles. I also need to determine weather to use log-polar or cartesian
rlm@73 32 for the visual input, and I need to determine how/wether to
rlm@73 33 disceritise the visual input.
rlm@73 34
rlm@73 35 I also want to be able to visualize both the sensors and the
rlm@104 36 effectors in pretty pictures. This semi-retarted creature will be my
rlm@73 37 first attempt at bringing everything together.
rlm@73 38
rlm@73 39 * The creature's body
rlm@73 40
rlm@73 41 Still going to do an eve-like body in blender, but due to problems
rlm@104 42 importing the joints, etc into jMonkeyEngine3, I'm going to do all
rlm@73 43 the connecting here in clojure code, using the names of the individual
rlm@73 44 components and trial and error. Later, I'll maybe make some sort of
rlm@73 45 creature-building modifications to blender that support whatever
rlm@73 46 discreitized senses I'm going to make.
