how to make a curved plane in threejs

I am projected a video into 3d geometry using threejs. The footage is from a gopro, so it's got a field of view of maybe 120degrees, so what I want is to be looking as if the footage were wrapped such that it bent a little at the sides, top and…

The fastest way to find the greatest possible area of triangle

Let's imagine that we have a set of points in the plane, each described by pair of integer coordinates. Is there a way to find the triangle with vertices on this points with the greatest possible area faster than by O(n^3) algorithm?

Camera Frustum Planes in Unity 3D

I understand that CalculateFrustumPlanes() in Unity3D returns an array of Plane objects, each representing a different frustum plane, but I can't find any documentation to suggest which element is which? for example [0] = Front [1] = Back etc. I…

algorithm for optimal subdivision (i.e. tessellation / partitioning) of 2d polygons into smaller polygons?

I've got some 2D polygons, each as a list of clockwise coordinates. The polygons are simple (i.e. they may be concave but they don't intersect themselves) and they don't overlap eachother. I need to subdivide these polygons into smaller polygons to…

Avoid distortion when inserting a rectangle into a point cloud using plane equation

I have a set of different point clouds, from each of which I find the plane with the largest supponrt and get the plane equation (ax + by + cz + d = 0) Using the plane equation, I am trying to insert a plane into each of the point clouds, which I…

Path that gets within given distance of each point in order

I have an ordered list of points in a 2D plane. I'd like to find the shortest route such that it gets at least within distance X (or closer) from each point, in the given order. How do I find this route? I realize that the points that will determine…

How to plot a 2D plane of set area, using a point on a plane and a normal vector, in 3D space, using plotly and dash?

I would like to plot a 2d plane of a set area (e.g. 10x10 square or 5dia cicle) in 3D space using plotly so I can include it in my dash app. I would also like to be able to rotate and position the plane in 3D space using a point on the plane (in the…

In a Unicode string, how are planes indicated (or are they not)?

I have read the article by Joel and have done a lot of searching. Every site and article on Unicode talks about how there are 16 bits per code point, but Unicode supports more than 2^16 code points with Unicode planes. But none explain how a Unicode…

Detect when 2 moving objects in 2d plane are close

Imagine we have a 2D sky (10000x10000 coordinates). Anywhere on this sky we can have an aircraft, identified by its position (x, y). Any aircraft can start moving to another coordinates (in straight line). There is a single component that manages…
