I am familiar with BSP, KD-tree and BVH for the general ray-primitive intersection finding problem. Are there any more efficient algorithms and data s ...
I should show a set of markers on map to indicate nearby points of interest. These markers will open public chat rooms by click and therefore I think ...
I'm facing a problem regarding "partitioning"/subsetting polygons into regions (bigger polygons) so that each region should have disjoint meaningful e ...
I have a point cloud of N points in D-dimensional space with periodic boundary conditions, where N can range from 500 to 10^8 and D can range from 1 t ...
I'm currently trying to implement quadtrees to partition a map. I have done research for the past week and wasn't to successful. I am trying to divide ...
I am currently working in an efficient calculation engine for particle simulation both in CPU and GPU. I have been working lately in octrees and I man ...
There seems to be a similar question here, but I was satisfied with neither the clarity of the answer, nor its practicality. I was asked in a recent i ...
I have many points (+100,000) in 3 dimensional space. I need to use nearest neighbor and range queries. Firstly I used kdtree (k=3) but each point has ...
Having dealt with converting the Bezier Patches into triangles, I need to do a Binary Space Partition in order to draw the projected triangles using t ...
I'm performing some MD simulations involving systems of millions of atoms. I have written some code to generate a file which is just a listing of XYZ ...
I have a 3d volume given by a binary space partition tree. Usually these are made from polygon models, and the splitted polygons already stored inside ...
I read about R-Tree, kd-tree, bounding interval hierarchy etc for space-partitioning. I found that these data structures are useful for spatial queryi ...
I'm writing an app that looks up points in two-dimensional space using a k-d tree. It would be nice, during development, to be able to "see" the neare ...
I have a 2D map which wraps at the edges. So if you move off the right edge you will reappear at the left side of the map. Likewise with the three oth ...
I have a region of space, 2 dimensions, from (0,0) to (MAX_X, MAX_Y). Inside this region of space, I draw some lines, they intersect the perimeter of ...
I've been trying to implement a spatial partitioning algorithm in my game, but both spatial hashes and quadtrees aren't what I'm looking for. My leve ...
I need algorithm which splits big static sized rectangle to small ones. A perfect implementation for me look like this: So I need algorithm for Get ...
I'm trying to store the data in a binary space partitioning tree in a relational database. The tricky part about this data structure is it has two dif ...
I have a set of points which are contained within the rectangle. I'd like to split the rectangles into subrectangles based on point density (giving a ...
