[Grasshopper Tutorial] 0114 Origami Fold using Kangaroo 2 (Slow ver.)

all right this is the first time voice-altering two grasshopper and tutorials so but I'm not sure how it's gonna be mmm I might just gonna shut up at some point when I concentrate I'll try to do my best so this time I would like to make a horror gummy structures using grasshoppers okay let's drop that so first off let's make a square grid and let's make the the number of x and y to be 5 and the size to be 1 for now and let's have let's explode this rectangle curve to 4 edges and take the middle point of the edges all right and then all the polyline close it and shift the list of shift ass groupid latin it dispatch move the the odd number one or the even number one the x-direction oh wait I think I might need to flip the matrix here yep and the x-direction half the size of the grid and group this purchase one simplify things and merge together and let's group this all right I don't need to show the plane okay now exploding [Music] [Music] and remove duplicate lines okay no I don't need the girl on the edge that's outside a rectangle or should I say a paper plane to fold so let's get the middle point for these one okay and make the rectangle multiply to get a X&Y that's like a bounding rectangle and point in corrupt the check right and if the number of two bits inside so I only need the one inside and this patch is to have all the line all right [Music] Expo DS and let's split this plane using split surface right now I got these let's compare two simple mesh join the mesh alright okay let's set a timer here then now what I need first is of course the geometry to show let's get given merge here and another one I need always it's a love this one the links a spring and I can get the edges using the mesh edges get the nega-chin the inner edge competitive spring okay and we'll begin okay and I also want the floor and some gravity for all the points in the mesh so I need to to the Z direction okay that's a ball most importantly I need to give a folding force which I could use could be ID angle or a hinge I guess this hinge could work so I need one two three four five six parameters huh and the thing I need to fold is the line I need to fold this DS these curves so the thing I need is the mesh that shares this line I mean this edge on this mesh so if this is the line and this is it's the mesh that I need to mesh that which shares the e this edge so I need to search it for so for each edges take a craft and there's the mesh here and whole geometry whole point hmm might not be a good idea Koval this mesh call this point does a kid let's try these are let's get the center point of th and the mesh B and I get the point here vocational mesh close to the search point ah so if it's smaller than wait a minute um what would happen if I is mass multiplication here pretty fast and everything is 0 it is smaller than 2001 and all the charm tree alright and join the mesh weld it and get the edge join the outside curve control get a control point no think is you don't know whether if it's you know if the curve is curves point order is clockwise or counter clockwise so I want to make it consistent meaning I could make a consistent using a simple trick make a really small offset curve and get the area or each curve compare those together [Music] maybe this is too small I'll make it yeah I think some of the curves are going in inside so I'm going outside when we offset it so I'm sure some of the point water is not consistent so and I can see that see that by making an offset yeah some archers are false okay that's dispatch flip it and wash it okay right now get control points without duplicate point alright and okay let's dispatch it and make finally I use this one that wanted to old start all dead and the rest angle to be okay right here right huh it weird not sure what's happening okay all right I don't have so I have 450 okay I think I need to remove the duplicate here all right okay let's raise up the plane a little bit upward still not sure laughing okay maybe I can [Music] make the strength of the ball a little bit weaker or stronger 400 and and disable these and it's not changing anything obviously that's because I'm just picking up one all right if I change this 200 change this may be the floor is too strong let me change this to 1 yeah but the other side is better I think let me preview it with a color I don't want to make it the other side I think I need to give it negative value here all right all right it's working good it's good it's good now let's make it a little bit bigger something like I know 15 would it be too slow to calculate it oh yeah maybe a bit slow oh oh it's tons of calculations oh she was using multi threat no offense um anyway let's try all right you Oh broken up let's make it ten okay well going well
