Gradient triangulation, prepared libraries for JavaScript?

You need to be quick to solve the problem of two-dimensional visualization — specified set of points in Euclidean space (x,y in the set limits), in the further their quantity will increase (filling the local area or expanding, it is not important) initially randomly uniformly distributed. Each point has a weight (maybe more...

How easy it is to break the face of the figure on the polygons (triangulation)?

Good afternoon. The task is to draw a three-dimensional figure (a cube, for example), using a polygon model. What is the easiest way to break the face into polygons (triangles)? I would like to use the number of polygons can be changed. Assume that after splitting, you will need to have access to each individual polygon col...

3D triangulation?

Hi! Don't know how to solve the problem with a 3D triangulation. Don't send me immediately to Google, I was already there, but still have questions. Let me first describe my task. As input I get "skeleton" of a 3D object consisting of lines. I need to triangulate this volume. Sounds simple, but the solution I found. Let's s...

Triangulation of the surface and its smoothing. How competently to implement?

In General the surface is set by the height map, namely two-dimensional matrix a[n][m] (a[i][j] = z, i = x, j = y). It is clear that the points are ordered so:1. Triangulation. The surface is divided into triangles like this: Or, in some cases: The right thing to do? Does it not like?2. Smoothing. Actually, the main questio...

What is the accuracy of navigation using a 360°camera and beacons?

I want to make a guard robot on a plot of 50 acres (170*300 m.), drove the same route. Camera 360° (with a more or less high resolution, but to 20,000 R. fit). I think the positioning to organize the IR beacons in the lights (they benefit perimeter every 10m. and 7 pieces in the middle of the plot). Would that give me a pre...

How to find the coordinates of a point on distance to reference points (triangulation)?

The crux of the matter, there are a few random reference points on the ground (their coordinates are known in latitude and longitude). Known distances from each of the sample points to the desired point. How to find the coordinates of the required point (latitude and longitude)? If there are ready-made algorithms or librari...

Triangulation point cloud in C++?

Looked CGAL, PCL, they are well up to the task of generating meshes from the point cloud, but their big disadvantage - they are bulky and have multiple dependencies, because of this their use in the client application because the same features will be unjustified. Well there Desktop, but need to port under the Web, where fi...

What are the positioning systems?

According to the study it is necessary to consider the system of precise positioning. But somehow the information, except for satellite, GSM and radar, cannot find. What are some other types of precise positioning? Share sources if possible, please. Thanks in advance for your answers.
