200+ FPS (on an simple laptop) about particle-life HOT 12 OPEN

Great job looking forward to it 👍 👍 💯

yes. I'll try to make something mergeable with the main project, and independent of oneAPI.

it took me a while. the code is unfortunately much slower on MSVC than on intel compiler. But still faster than the previous version of course.

i also removed the dependency to intel TBB so no 200FPS (it can still be seen in commented code however)

Hi! I want to set different particle sizes depending on their type. For example, red should be 1.0 pixels, green 1.2 pixels, blue 1.4 pixels, and so on. I saw in the code that a size is defined for all particles in ofApp.h. How could I condition this particle size with an "if"?
I'm referring to this piece of code:
void draw() const
{
ofSetColor(r, g, b, 100); //set particle color + some alpha
ofDrawCircle(x, y, 1.5F); //draws a point at x,y coordinates, the size of a 1.5 pixel circle
}
My colors are defined by generic names:
void ofApp::restart()
{
if (numberSliderα > 0) { alpha = CreatePoints(numberSliderα, 0, 0, ofRandom(64, 255)); }
if (numberSliderβ > 0) { betha = CreatePoints(numberSliderβ, 0, ofRandom(64, 255), 0); }
if (numberSliderγ > 0) { gamma = CreatePoints(numberSliderγ, ofRandom(64, 255), 0, 0); }
if (numberSliderδ > 0) { elta = CreatePoints(numberSliderδ, ofRandom(64, 255), ofRandom(64, 255), 0); }
if (numberSliderε > 0) { epsilon = CreatePoints(numberSliderε, ofRandom(64, 255), 0, ofRandom(64, 255)); }
if (numberSliderζ > 0) { zeta = CreatePoints(numberSliderζ, 0, ofRandom(64, 255), ofRandom(64, 255)); }
if (numberSliderη > 0) { eta = CreatePoints(numberSliderη, ofRandom(64, 255), ofRandom(64, 255), ofRandom(64, 255)); }
if (numberSliderθ > 0) { teta = CreatePoints(numberSliderθ, 0, 0, 0); }
}

I would like to define something like:
void draw() const
{
ofSetColor(r, g, b, 100); //set particle color + some alpha
if (numberSliderα > 0)
{
ofDrawCircle(x, y, 1.0F); //draw a point at x,y coordinates, the size of a 1.0 pixels
}
if (numberSliderβ > 0)
{
ofDrawCircle(x, y, 1.2F); //draw a point at x,y coordinates, the size of a 1.2 pixels
}
if (numberSliderγ > 0)
{
ofDrawCircle(x, y, 1.4F); //draw a point at x,y coordinates, the size of a 1.4 pixels
}
if (numberSliderδ > 0)
{
ofDrawCircle(x, y, 1.6F); //draw a point at x,y coordinates, the size of a 1.6 pixels
}
if (numberSliderε > 0)
{
ofDrawCircle(x, y, 1.8F); //draw a point at x,y coordinates, the size of a 1.8 pixels
}
if (numberSliderζ > 0)
{
ofDrawCircle(x, y, 2.0F); //draw a point at x,y coordinates, the size of a 2.0 pixels
}
if (numberSliderη > 0)
{
ofDrawCircle(x, y, 2.2F); //draw a point at x,y coordinates, the size of a 2.2 pixels
}
if (numberSliderθ > 0)
{
ofDrawCircle(x, y, 2.4F); //draw a point at x,y coordinates, the size of a 2.4 pixels
}
But Visual Studio gives me errors because these sliders are not defined here (they are defined in the GUI, class ofApp final : public ofBaseApp).
Please help me!

i assume your are referring to old codebase. Can you post a link to your code ?

the easiest way to do this would be to add a radius property to the point struct. and then you would just ofDrawCircle(x, y, radius)

Here is my last version of the code.

I tried the new code, but it works extremely hard. I couldn't get more than 8 fps at 8 colors of 1000 particles each. Then, another shortcoming of the new code is that the particles look extremely small, like little dots where you can't really distinguish the color shades. The structures formed don't look good at all because of this.

I also tried to insert a fullscreen button but it didn't work. I used ofToggleFullscreen(), but the screen kept blinking without showing anything.
I'm also trying to figure out how to introduce the 3D vision function (with 3D glasses).
Also, I don't know how to save the color palette generated before saving the model. The particle colors are generated when pressing the buttons that trigger the restart. But when I save the model, the existing colour palette is not saved so that I can load it later. Do you have any idea how I could save this color palette?

I'll take a look at your code, and also patch my code to allow drawing circle.
my code shouldn't be slower. this is weird. are you using openmp in your code ? I might have forgot to reenable it.

I'll check the fullscreen problem as well.

I took your exact code and just added more colors and those extra buttons. And after compiling, the code worked extremely hard. I had to set a small number of particles (under 1000 of each color) to go at 10 fps.

Here is your code with my additions in it in old way, that works fine with 17313 big particles at 61 fps:
src 1.7.6.5.zip

Here is a proof screenshot:

Here is your code with my additions in it but in new way, that works slow and particles are very very small (near dots) with 9600 particles at 4 fps:
