Hi Thomas, sorry to disturb you again. I was trying to use the 30⁰ rule for a river but it is loosing shape while extruding.  Lot --> extrude(world.up, dist) comp(f) {front: Slope } Slope --> rotate(abs,scope,90-angle,0,0) extrude(world.up,0.1) Visualisation Visualisation --> color(0,1,0) set(material.opacity,Transparent) I am not able to figure out how to solve this. Thanks in advance. ... View more

Thanks Thomas, it works perfectly now. ... View more

Hi Thomas, I tried using the code you have provided. But doesn't generates like you have shown in screenshots. Does occlusion works in same parcel/footprint . Code Used  Code_1.cga :-  version "2016.1" @Range(0,1,2) attr LOD = 1 attr maxFloors = 50 attr floorheight = 4 @StartRule Lot-->      offset(-3)      comp(f) { inside: Initial }       Initial-->      extrude(maxFloors*floorheight)      FloorSplit FloorSplit-->      case overlaps(inter):           split(y){~1:FloorSplit | floorheight: Outside}      else:           case LOD < 1: Mass           else: split(y){~1:FloorSplit | floorheight:  Floor} Mass--> color("#0000ff") Floor--> color("#00ff00") Outside--> color("#ff0000") // or NIL Code_2.cga :- version "2016.1" @Range(1,89) attr angle = 30 @Range(50,1000) attr dist = 500 @StartRule Lot -->      offset(dist)      comp(f) { border: Slope }       Slope-->      rotate(abs,scope,-angle,0,0)      extrude(world.up,1)      comp(f){bottom:     Visualisation}       Visualisation--> set(material.opacity,0.3) ...

Hi,  I have tried using recursion to check the floors generated, but somehow its not generating exactly the total number of floors. I have attached the cga script bellow , can you help me where I am going wrong. Thanks in advance ... View more

Thanks Thomas, your code was really helpful to understand various ways to use functions. I tried this code and works perfectly, but since my plots are getting divided base on the plot dimension say, 30*40, so I am not able to figure out how to incorporate this code. Basically I split my parcels in grids using split function and generate give 30% probability to cover 30% ground cover for buildings and then randomize heights between max floors and min floors. Since I am working with FAR concepts now I have total number of floors fixed. I hope we can incorporate your code in mine. Here is my code getHeight(row_ind, nRows, col_ind, nCols) = GfHeight + nFloors(row_ind, nRows, col_ind, nCols)*UfHeight nFloors(row_ind, nRows, col_ind, nCols) = case Variation_Mode == "None" || (nRows*nCols) < 2 : Floor_Max case Variation_Mode == "Increasing" : Floor_Min + (rint((Floor_Max-Floor_Min)*((row_ind*nCols+col_ind)/((nRows*nCols)-1)))) case Variation_Mode == "Decreasing" : Floor_Min + rint((Floor_Max-Floor_Min)*(1-(row_ind*nCols+col_ind)/((nRows*nCols)-1))) case Variation_Mode == "Alternating" : Floor_Min + rint((Floor_Max-Floor_Min)*((row_ind*nCols+col_ind)%2)) case Variation_Mode == "Plot_Increasing" : Floor_Min + (rint((Floor_Max-Floor_Min)*(col_ind/(nCols-1)))) # case Variation_Mode == "Plot_Decreasing" : Floor_Min + (rint((Floor_Max-Floor_Min)*((1-(col_ind))/(nCols-1)))) ///// Not Working case Variation_Mode == "Plot_Alternative" : Floor_Min + (rint((Floor_Max-Floor_Min)*(col_ind%2))) else : rint(rand(Floor_Min-0.49,Floor_Max+0.49)) @StartRule Lot -->    set(Plot_Area, geometry.area)    report("Plot Area", Plot_Area)    Lot2 Lot2 -->    split(x) { Width: Col(split.index, split.total)}* Col(col_ind, nCols) -->    split(z) { Length: Cell(split.index, split.total, col_ind, nCols)}* Cell(row_ind, nRows, col_ind, nCols) -->    print("total cels " + (nRows*nCols))    print("row_ind " + (row_ind*nCols+col_ind))    DevelopLot(row_ind, nRows, col_ind, nCols) DevelopLot(row_ind, nRows, col_ind, nCols) -->    case p(BuildPer/100) : ExtrudeBuild(row_ind, nRows, col_ind, nCols)    case p(OpenSpacePer/100) : Openspace    case p(GreenspacePer/100) : Greenspace    else : Greenspace ExtrudeBuild(row_ind, nRows, col_ind, nCols) -->    extrude(world.y, getHeight(row_ind, nRows, col_ind, nCols))    split(y){GfHeight : Done. | ~1 : UpperFloors} UpperFloors -->    split (y){~UfHeight : Done.}* ...

Its been quite some time for this post. Thanks Cherly, I have used most of the expression suggested by you.  I have some query regarding this, Since we can achieve total number of floors from ((FAR*SiteArea)/SiteArea). Can this be applied with a given Minimum and Maximum floors per lot. So that all the buildings in the plot will not cross total number of floors given and can be randomize the heights between maximum floors and minimum floors. I hope this make sense, I able to find the logic but its difficult to put in CGA Script. Regards Abhishek ... View more

My best guess is, you can try SplitArea function, lets say BCA is 0.5 (50% of ground cover) splitArea(x) {(geometry.area*(1-BCA)) : GreenSpace | ~1 : Extrude_Building} I hope this helps you. Regards Abhishek ... View more

Hi,  GFA & FAR Calculations with CityEngine - YouTube, I hope this tutorial will help you to figure out FAR. Regards Abhishek ... View more

Thanks for the Tutorial, helped me a lot to understand more ways to write my code. But I am not sure how to put a handle in my code since it is generated from  GFHeight + nFloors*UFHeight Here is my complete code Lot -->    split(x) { Width: Col(split.index, split.total)}* Col(col_ind, nCols) -->    split(z) { Length: Cell(split.index, split.total, col_ind, nCols)}* Cell(row_ind, nRows, col_ind, nCols) -->     extrude(getHeight(row_ind, nRows, col_ind, nCols) ) ////////////////////////// getHeight(row_ind, nRows, col_ind, nCols) = GfHeight + nFloors(row_ind, nRows, col_ind, nCols)*UfHeight nFloors(row_ind, nRows, col_ind, nCols) =     case Variation_Mode == "None" || (nRows*nCols) < 2 : Floor_Max     case Variation_Mode == "Increasing" : (Floor_Min) + (rint((Floor_Max-Floor_Min)*((row_ind*nCols+col_ind)/((nRows*nCols)-1))))    case Variation_Mode == "Decreasing" : Floor_Min + rint((Floor_Max-Floor_Min)*(1-(row_ind*nCols+col_ind)/((nRows*nCols)-1)))    case Variation_Mode == "Alternating" : Floor_Min + rint((Floor_Max-Floor_Min)*((row_ind*nCols+col_ind)%2))    else : rint(rand(Floor_Min-0.49,Floor_Max+0.49))     //////////// Random Height Function I can't put handle on both GFHeight and UFHeight in the attribute because both will be constant from the attribute. I saw the seedian shape attribute in help link but didn't get it properly how to apply in the code. It will be great if you can provide some example on using "seedian shape attribute" Thanks  ...

Does @Handels works on 2015.2 advance version? My height function is not defined in attribute, it from the GF_Height and UF_Height, getHeight(row_ind, nRows, col_ind, nCols) = GfHeight + nFloors(row_ind, nRows, col_ind, nCols)*UfHeight nFloors(row_ind, nRows, col_ind, nCols) =    case Variation_Mode == "None" || (nRows*nCols) < 2 : Floor_Max    case Variation_Mode == "Increasing" : (Floor_Min) + (rint((Floor_Max-Floor_Min)*((row_ind*nCols+col_ind)/((nRows*nCols)-1))))    case Variation_Mode == "Decreasing" : Floor_Min + rint((Floor_Max-Floor_Min)*(1-(row_ind*nCols+col_ind)/((nRows*nCols)-1)))    case Variation_Mode == "Alternating" : Floor_Min + rint((Floor_Max-Floor_Min)*((row_ind*nCols+col_ind)%2))    else Lot -->    extrude(getHeight(row_ind, nRows, col_ind, nCols) ) I am looking for a seed function like in block division shape parameters. Is it possible to have such function in the code. ... View more
