as you can see from TFGuy44 Code, peasyCam is not the only way to have 3D rotation.
He wrote his own rotation based on mouse.

here is an example of mouse rotation without _peasyCam_ based on TFGuy44’s Code
```auto
void setup() {
size(600, 400, P3D);
background(0);
}
void draw() {
background(0);
lights();
// the core idea:
setRotationAccordingToMouse();
// Example shape
drawBoxWithSphere();
}
// -----------------------------------------------------------------
void setRotationAccordingToMouse() {
// rotate and text out the two angles
// calc angles
float xAngle = map(mouseX, 0, width, -PI, PI) ;
float yAngle = -map(mouseY, 0, height, -PI, PI);
// text out the two angles
showAnglesAsText(xAngle, yAngle);
// rotate
translate(width/2, height/2, 0);
// angles swapped!
rotateX(yAngle); // up/down
rotateY(xAngle); // left/right
}//func
void drawBoxWithSphere() {
pushMatrix();
// Box
fill(255, 0, 0); // RED
noStroke();
box(60, 70, 50);
// Sphere
translate(0, -49, 0);
fill(0, 255, 0); // Green
sphere(20);
popMatrix();
} // func
void showAnglesAsText( float xAngle, float yAngle ) {
// text out the two angles
fill(255); // WHITE
text( int(degrees(xAngle))

+"°",
20, 20);

Your design is assuming that your values will be evenly distributed (equal number of lefts and rights, or ups and downs) – but they are not, even if all values are randomly generated. For previous discussion and workarounds / solutions for that general issue, see:
- [Why does it seem the noise() method is negatively biased? - Processing 2.x and 3.x Forum](https://forum.processing.org/two/discussion/comment/109333/#Comment_109333)
In general, don’t accumulate long series of random values – make them independent – and you won’t get tendencies over time that converge in one direction.

Been thinking about how to go 3D in terms of your sketch regarding to #3.
You could distinguish between upper case and lower case letter.
When the new letter is upper case and is smaller than the previous one, turn left by 90 degrees otherwise right 90 degrees. Using rotateY.
Now using rotateX you can use lower case and check if the letter is smaller or bigger and turn the angle UP 90 degrees or DOWN 90 degrees.
Then just draw a straight line with this rotation and store it in your ArrayList.

> The harder part is that at the moment all lines are in one plane. So to look at it in 3D might be boring. To make this interesting we would need a drawing in 3D space instead of in a 2D plane only. This is a bit tricky because for 3D you have at least 2 angles, left/right (like now) and up/down (new). You could for example use all small letters for the 1st angle and all capital letters for the 2nd angle.
When I wrote #3 I was referring to this text section

apologies for the late response.
1. With “If it’s uppercase and **is smaller/bigger than the previous letter…** ”. Do you mean with the “smaller/bigger than” part the value minAngle/maxAngle value?
2. What exactly do I need to rotate to get the desired effect? do i need to rotate the `float x` and `float y` (which are used in a formula like `float x = r * cos(radians(angle+offset)) ;`); or do I rotate the angle?

1.
just if the ascii of the letter is \> or \< than the prev letter.
The approach is a little different, instead of using all angles in the circle we just turn left or right 90 degree
1.
No, it’s a new approach without sin and cos
It’s essentially a 3D Turtle (see LOGO In Wikipedia) or a 3D L-System. I have just hard coded the letters wasdf but you can also do a \< \> check as I described. You could also map the ascii to angles and use in the rotations

You could also use peasycam instead of the mouse function
There also is a rotateX and a rotateY, not the same for letters a and d
There are 6 rotations

Is it possible to change the PeasyCam handling to another button? For example, instead of using the middle-mouse to pan left/right/up/down, can I asign it to like the arrow keys?

hmmmm i ran into something strange.
When I use my PowerShell code to use te powershell as a keylogger, get my .txt from it and save it + use it, for some reason the program won’t properly pick up on ascii values and wont create any turns, but it will act normal when i copy all the button input, open notepad myself, paste it in there and re-save under the same name.
Guess there is soething wrong with the .txt that Powershell makes?

maybe somebody else answers. Do you use loadStrings to load your code?
Meanwhile I have a new 3D demo
- you can use PeasyCam

My very last question, and to repeat myself: Thank you for all the help!
So I do not know if you personally worked with Arduino before, but I want/need to add the rotation of the camera to my Arduino button. I already checked as much of PeasyCam stuff as I could, but I do not think it would be possible.
In the None-peasycam alternative piece of code, I could change mouseX and mouseY to
```auto
float xAngle = map(arduinobutton1, .....);
float yAngle = map(arduinobutton2, .....);
rotateX(xAngle);
rotateY(yAngle);
```
Correct?

Okay… this is really my last question
.
So I am implementing just a simple zoom to the project, basically with ( **This is just the code that is added to the project** ) :
```auto
float zoom = 1;
boolean zoomIn = false;
boolean zoomOut = false;
void draw() {
translate(width, height);
scale(zoom);
zoomCamera();
}
void zoomCamera() {
if (zoomIn) {
zoom += 0.03;
}
if (zoomOut) {
zoom -= 0.03;
}
}
void keyPressed () {
if (key == 'j') {
zoomIn = true;
zoomOut = false;
}
if (key == 'k') {
zoomIn = false;
zoomOut = true;
}
void keyReleased() {
if (key == 'j') {
zoomIn = false;
}
if (key == 'k') {
zoomOut = false;
}
}
```
And the issue is that I cannot get the ‘Translate’ right to show my sketch on my screen AKA I have to zoom in or out to find it. Would you know how to find the proper translate-coordinates or wont it be necessary? (I keep seeing Translate being used with a few videos).
