### Existing software/scripts for spiral graphs?

I am looking for existing software or scripts to generate spiral graphs from cyclical (time) data, as presented by Webber and Muller. The graphs shown in the paper look like a great means of ...

### C60 orbital calculation

I am currently trying to reproduce the results published by Hands et al.1 using MATLAB. They calculated the bases of the C60 wave functions of HOMO, LUMO and LUMO+1. I did the following: I ...

### Is there a library which allows for converting 4D implicit surfaces to simplexes?

I have a 4D surface in the form of the spin quadric. I would like to display this surface onto the screen. One of the method which I would like to use to present surface onto the screen is projection. ...

### Developing a meshfree contouring algorithm

I would like to find the contours of a scalar function $u(x,y)$ available as a discrete set of function values $u_i = u(x_i,y_i)$ over a scattered set of points $(x_i,y_i), i=1,...,N$. In my case, the ...

### Piecewise-linear Continuations vs Marching Squares/Cubes

It seems that both piecewise-linear continuation and marching squares are methods to produce iso-contours of a scalar function given the function's values on a grid. It seems that piecwise-linear ...

### Showing date in Paraview's Annotate Time Filter

I have a time dependent data set where each frame corresponds to a certain date. I need to show the time annotation, much like what Annotate Time Filter does, but show the date instead of time as a ...

### Numerical flow visualization in 2D for a moving boundary,

I have a rigid body that moves according to a set of governing ODEs, and I'd like to numerically visualize the vortices that are shed by this object. How could I proceed? I've been reading up on the ...
