Just a Dot on the Screen, is it Normal?

[AnonymoZ]

All controls work, but each attractor shows me only a dot:

Is this normal?

To make the code work on Code::Blocks I made a few adjustments:

• #include "stdafx.h" → //#include "stdafx.h"
• sf::color::color(38, 142, 234, 76) → sf::color(38, 142, 234, 76)
• LorentsAttractor.run(window) →

  LorenzAttractor rf;
  rf.run(window);

Made the same changes and having the same issue as Anonymoz.

If you write float speed = 2.f; in LorenzAttractor.h and set unsigned num_points = 1000; for instance, it will work!

Ah! We've figured it out! Beautiful things to look at! In addition to all above changes, in LorenzAttractor.h, change unsigned trail_length = 50; → unsigned trail_length = 500; This will make the trails appear longer and more beautiful!

Next, here are the instructions on how to use the software once it is executed and you can see the name of the attractor on a black screen:

• You will first see just a dot. Press “Page Up” to begin the animation.
• Move to the next attractor with “H” and to the previous attractor with “G”.
• Press “Page Up” and “Page Down” now to control the speed of the motion.
• Use the Arrow Keys, “W, A, S, D” and also “LShift and Space” to move the camera. The Arrow Keys will only tilt the camera angle, while “LShift”, “Space”, “A” and “D” move “↑”, “↓”, “←”, “→” respectively. And finally “W” and “S” zoom in and out of the canvas.
• Press “Esc” to exit the program.
• Change to fullscreen or not with “F”.

Overall the program is cool, but here are room for improvement:

• Add more dots—the more the merrier.
• For long trails we'd like smooth not polygonal movement.
• Some attractors appear to diverge out of the screen. There seem no way to bring them back.

Hello, thanks for the extra infos!
