Hello people!! I built a code on a lamp that goes on and off, the idea was to talk about the frequency in Hertz that a common lamp goes on and off, so I created a “simulation” of it. The draw function as far as I know runs at 60 fps, why even at that frequency we can still observe an Oscillation i…

The maximum frameRate depends on the time needed to process what you are drawing, on your computer processing power, and sometimes on process interference from other not sketch related computer tasks. If you for instance draw just an ellipse on the background it will reach a high frameRate. With th…

Hi @Willian_Xz Let’s assume that the lamp off would have a black color. When switching colors between frames, even at a frameRate of 60, you will see actually a lamp “color on” 30 times a second. (the other frame was black) If you have an Arduino you could test at what range you still would notice…

I find that strange … Even increasing the FPS by the frameRate function, placing it around 100 or more, we can still see an Oscillation between the frames of light on and light off. In theory, just running at 60 fps, we couldn’t see this oscillation, however we could see it even increasing the FPS…

Hello, You are also limited by the refresh rate of the monitor. :)

Really, this frameRate even set above 60, it doesn’t work … Literally it only reaches a maximum of around 60 and this oscillation between 57, 58, 59, 60, 61, makes us able to perceive the flashing light. The problem with frameRate is that even specifying to run only at 60 fps, it can’t … and it ca…

The topic is actually interesting. I believe that the irregularity also comes from the fact that frameRate is given by an average of 10 frames(?). Meaning that there can be long pauses (relatively) between frames. But that’s a guess. Maybe someone with a deeper core knowledge can respond. I also …

This statement is for P5.js: [image] glv: You are also limited by the refresh rate of the monitor. Some testing with my hardware reveals… With p5.js: The frameRate() that you set is capped at the refresh rate of your monitor. Lower values than refresh rate can be set. My monitor has a re…

[image] noel: The topic is actually interesting. It sure is! This may also be of interest: [image] FrameRate hiccups Coding Questions I had some fun visualizing the data available to me. I displayed frameRate data (which averages) to framerate calculated from tim…

Oh, great! I totally missed that one. But now, I also lost my hope for a solution. :frowning_face:

p5.js has deltaTime to easily inspect inter-frame delay without averaging. Here is an interesting detailed over view and tutorial on inspecting browser frame rate. It is specifically about using Mozilla Firefox browser developer tools, but it gets at some of the key ideas for rendering with JavaScr…

I still was thinking of that and I remembered that some years ago It was very hard for me to fall asleep. So I made a device that really helped me. I used some old glasses where I build some LEDs in, and an Arduino, which started flickering at the highest brainwave frequency Beta (35 Hz) down to Al…

It sure is!

This may also be of interest:

I may try this with P5.js sometime…
