Hi all, I'm testing the a colour tracker based more or less on Paul Smith's video, but instead of testing the colour difference I'm currently evaluating 4 vectors that hits the red ( North, South, West, East ) and get the average position to keep the particle in the center
Two things I do not understand: 1. The tree is more or less like this (a grid and an emitter which create the point cloud ) Get grid > raycast > plug point position on the "Position" port of the Raycast > plug a 3d vector on the "Direction" port > Get Texture Map > Color to RGBA > scalar to 3D vector > Set Data ( temporary value called "X plus" ) This tree is repeated in total 4 times, to get the N S W E values that I need If I put a random value on the "Direction" port of the Raycast and I play the animation, I can see the particle move around, and if I show visually the vectors I can see them firing around from the point But if I put a 3d vector into the "Direction", say I put X=5 and Y= -1 and I play the animation, I see the particle moving, but the vector that fires from the point do not follow my particle, but stays in the same position, so I'm not sure if its doing what it should be doing or not 2. If I fire 3 different rays from the particle its working properly ( I can clearly see 3 rays pointing downward the grid, each one on its different direction ), but if I fire 4 rays ( sp N S E W ) somehow the vectors are pointing almost straight down on the grid ( ignoring the "Y= -1" ) and the axis are not oriented properly There is something that I'm not setting properly and something that definitively I don't understand about the Ice tree that I created, and I would like to know what it is Could you give me an advice? Later this afternoon I'll try to post the Ice Tree to show better whats going on Cheers
