I have to study how to sort points because in this simple way I'm drawing hidden points over visible points  :(
Nicely done :t

looks great :t
but maybe a simple way with blending would be an option:
pixel=(newpixel+oldpixel)/2
or if you use many different colors, do this for each Red,green,blue channel

That could be better than now, but it's not the solution. Thanks.

Good point, Héctor. Here is my version, just a starting point, I have to improved it. No zbuffer, etc. When finished, if anyone interested, I may release the source code. Nacho división :eusa_boohoo:

Fantastic  :t

We will be waiting source code  :biggrin:.

No more time working on it, so here are the source codes. A lot of improvements can be done.

Just a few news:
- A brighter color for the points
- Zbuffer applied. Points in the background should be in the background now.

The program takes a little while to initiate. After that, if you wait for a few minutes you will see all its attractive as all the points start to displace rotating visibly

Great caballero  :t
Wouldn't it be possible to use stars instead of points and scale it in one axis to 15% so you get a milky way kinda galaxy?

Regarding this subject. I have been trying to simulate a star by code, drawing it. But the results are not very realistic. I left here a program in the first stage.

The principle is:
  - Drawing four larger light rays on the main axes of the plane
  - Other shorter four oblique to the previous ones
  - A central circle diffusing as it moves away from the center
 
As it has not convinced me too much, if you press the "1" button, this box will be blurred. Then four different quadrants appear, it would be interesting to know the opinion of which could be more realistic, if any

Maybe the first stage is not so bad after all.

Thank you.

Hhhhhmmm Maybe another idea is, defining some directions on random for example and diffusing it as going further from the center.
