  1. It looks like but it's no poisson distribution.
    Here I developed a remesh algorithm at first in two dimensions:

    Random points are moved more and more in the middle of their neighbours to avoid bulks of points (vertices) and create a base mesh that can be implemented in 3D to remesh sculpted objects.

    Currently I also work on a 3D example which has not reached the state to post it.

    Which remesher do you use if you work in 3D? And what could be a nice feature to implement in my algorithm?

  2. My #Sega #Dreamcast #programming #book is divided into 4 volumes, each covering a major area of discussion. The first volume is "Foundational knowledge," stuff not strictly about the Dreamcast, but things relevant. I.e. Matrix math, or bits and bytes. So when we're talking later about bitpacking an #FPU register to transform #polygon #vertices, people aren't lost. This was one of the hardest parts of the entire book to write, but it's finally "done" and ready:

    It wound up being 122 pages long.

  8. Hi again, friends of #visual #shaders! This time, we'll finally get to a no less important function, which is responsible for modifying #vertices and subsequently deforming the entire texture that the #shader is applied to. As an example, I chose the implementation of a flag that ripples in the wind. #GodotEngine #Godot #Godot4 #GodotTips

    The basic chaos game uses random vertex selection, perhaps constrained (e.g."don't pick the same vertex twice in a row").

    I experimented w. integer sequences of various sorts, e.g. the Fibonacci, which you take mod the #vertices. If you just use the first N numbers of this sequence repeated, and N < #points, interestingly, you only get N distinct points plotted!

  10. @christianp The number of trees you need for a graph is called its arboricity — see en.wikipedia.org/wiki/Arborici

    It always equals the maximum, over subgraphs, of #edges(subgraph)/(#vertices(subgraph)-1), and can be computed in polynomial time.
