Graphics: Marching Squares - Javascript implementation

Last post of this series dedicated to Contoured Lines with the whole Javascript implementation of the Marching Squares algorithm described here [Link] and there [Link]...

Graphics: Marching Squares - Rendering with Blender

In the previous post, we wrote a Javascript program to compute the contour lines of an object of interest and save the results - a set of (X,Y) coordinates - in a Wavefront OBJ file.
The last step is to render this geometry in Blender [Link] - a very powerful and popular 3D software...

Learning Tomography: Data Collection

Even though this blog is not focused on the experimental devices, it is interesting to have some ideas about the experimental data collection. I created videos to explain the various strategies used in science...

Graphics: Isocontoured Lines

In this series dedicated to 3D rendering, this is a preliminary post describing how to extract vectorial isocontoured lines from an image. One of the most popular algorithm is the Marching Squares algorithm.
The next step will be the computation of isosurfaces...

Fourier: Convolution and Deconvolution

Convolution is not an operation only specific of real space filters. You can use it in frequency space. Its counterpart - the deconvolution - is also very popular to enhance images.

Fourier Series: Several functions

Second post dedicated to the Fourier series [Link] with several examples of classical periodic functions.
