3d bin packing algorithm

first of all budget is 125usd. please click that link: [login to view URL] and then please click demo. this is the work. web user can define container/containers with Id Wdt Hgt Dpt Max. wgt. so each one can be different values. web user also can define box/ boxes with Id Wdt Hgt Dpt Wgt Qty. and it should be "pack" button. i just need results for each boxes. can app put selected box in to container? yes or no? box is rotated? yes or no each box position with x1,y1,z1 and x2,y2,z2 values. each box has order. example: third box is going to put in the first container as a second order line. (second step) i need this details for each box. i need these results details also for container: SpaceConsumed:x%, WeightConsumed:x%. let me show you one example result for one box: BoxID:1 ContainerId:1 ProcessStepNumber:1 TypeID:1 Length:1 Height:1 Width:1 Volume:1 isRotated:False x1:0 y1:0 z1:0 x2:1 y2:1 z2:1 Weight:10 actually, i have already this project: [login to view URL] but weight feature is missing. you need to add max weight for container. and you need to add weight feature for box. you can compare your result with [login to view URL] your result can be better than this web site. but your result cant be worst than this web site. and when you are done i need documentation for this example: you need to show me formula with math details step by step: CASE1 CONTAINER DIMENSIONS: 2X2X2 MAX WEIGHT: 80 KG BOX TYPE A DIMENSIONS 2X2X1 WEIGHT 40 KG PIECE 1 BOX TYPE B DIMENSIONS 1X2X1 WEIGHT 20 KG PIECE 1 BOX TYPE C DIMENSIONS 1X1X2 WEIGHT 30 KG PIECE 1 BOX TYPE D DIMENSIONS 1X1X1 WEIGHT 10 KG PIECE 4 BOX TYPE E (CANT GO IN TO CONTAINER BECAUSE OF THE VOLUME AND LENGTH DIMENSION SIZE) DIMENSIONS 5X1X1 WEIGHT 40 KG PIECE 1 BOX TYPE F (CANT GO IN TO CONTAINER BECAUSE OF THE DEPTH DIMENSION SIZE) DIMENSIONS 2X2X3 WEIGHT 40 KG PIECE 1 if you also add case2(below) in to document i can pay you extra 25usd. here is the case 2 for same problem: EVERYTHING IS SAME. JUST CHANGE WEIGHT OF THE BOX TYPE C LET'S SET IT to 20 KG. IT WAS 30 KG. this is the case2. so case 2 is up to you for documentation. you can add some shapes if it is okay for you. i will be appriciated. thanks. selcuk
