2d Bin Packing Software S
There are a few similar questions on stackoverflow, but none of them seem to provide a tangible answer that someone without a solid understanding of NP-hard problems and algorithms can understand. How does one perform 2D bin packing of rectangular objects? In my case, I'm trying to assemble several images into a single image, for use as a spritesheet, using the smallest amount of space. Each image possibly has wildly different bounds, but there is no set bounds to the container. I was hoping someone with an understanding of bin packing algorithms could explain how this can be achieved programmatically, rather than providing a general overview of the bin packing method.
And this was my first hit: Here's a summary: build a binary tree. Each branch in the tree contains a sprite. Each leaf node represents available space. Initially the tree has just the root node, which represents all available space.
To add a sprite to the tree, search the tree for an unoccupied (leaf) node big enough to hold the sprite. Turn that node from a leaf into a branch by setting the sprite as the node's occupant and giving the node two children. One child represents the remaining space to the right of the sprite; the other represents the remaining space below the sprite and the first child. The article I linked above explains this much more fully, with diagrams and JavaScript code. It also explains how to dynamically grow the sprite sheet rather than choosing a fixed size in advance.
We need a 2d bin packing program. There is.NET code available at url removed, login to view for bin packing.
Software Engineering MCQs. Such as 2D packing, linear packing. Here is source code of the C++ Program to Implement the Bin Packing Algorithm.
3d Bin Packing
I have several enhancements which need to be added to this software. Enhancements - 1) sizes need to go to 4 decimal places and outer rectangle needs to be configurable up to 60x100.
Bin Packing Algorithm
2) there should be a button which loops through all methods to find the best result. I need to be able to configure the procedure which calls those methods so that only certain methods are included so when I'm doing 20 rectangles I don't get stuck with the methods which will take forever. 3) there should be a loop which tries to get a better result by switching the height and width values (same as 90 degree rotation) of every rectangle. If there's 8 rectangles, that's only 64 combinations. 4) ability to log the results 5) ability to print layout ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment-Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment.
