### Schwarz–Christoffel-like mapping on differentiable simple cubic spline boundary

For a concept of a computer game I have in mind I came to need that. I have a 2D pond, which has a boundary that is a simple differentiable cubic spline. There are ducks floating around, looking at ...

### Calculate base and coefficient for power curve through 3 non-linear points

I have a formula that takes a 0-based bounded single dimensional input and transforms it to a specific power curve. EDIT This is single dimensional. There is no $y$. In the image, I'm showing how ...

### Level set of 2D gaussians

I'm looking for a numerical method to rapidly find the level set $\{x,y\} | f(x,y)=h$, where $f(x,y)$ is a sum of a 2d gaussians (forming a mixture model), and $h$ a constant. Here's an example ...

### Formula for intersection of “power” curve and parabola.

EDIT I have edited this question to make it more clear. I have spent quite some time trying to find this on Google, but haven't succeeded. I need the formula(s) to determine the intersection ...

### Cutting of the Delaunay triangulation

I am working on terrain rendering tool currently. I have to cut a piece from a given Delaunay triangulation. Suppose following triangulation is given: The red square depicts area to cut from the ...

### Computing a volume (area) of intersections

The task should be very common, what are the best and easiest to implement algorithms to compute the volume of union/intersection of given bodies? Or union/intersection area for 2D figures. I don't ...
We know that Cox-de Boor recursion formula can be used to compute the B-spline basis function.  N_l^n(u)=\frac{u-u_{l-1}}{u_{l+n-1}-u_{l-1}}N^{n-1}_l(u)+ ...
