I just updated my processing to 3.5 and I saw that they added circle () and square()  
Does anyone know the syntax and parameters of these functions? I think it’s exciting to have these new features.

```auto
circle(int x, int y, int diameter);

```

prints a circle at location `x`, `y` with a diameter of `diameter`

```auto
square(int x, int y, int wh);

```

prints a square at location `x`, `y` with a width and height of `wh`

By the way, did you know that processing has code suggestions if you enable them in preferences and press ctrl+space while typing? It’s very useful.

The actual documentation will probably be updated within a day or so.

you see this already?

( as the above reference states ) can not test on Raspberry Pi RASPBIAN linux until available, but on win 7 64bit and right int diam=200; // used for eclipse and mandatory at rev 3.5 ??? void settings() { size(200,200); } void setup() { // …

and pls. use

Radius? Function **ellipse()** uses diameter by default for both its _width_ & _height_! 😶

You’re right. My bad. Edited my original post.

For completeness’ sake, we can make **ellipse()** (possibly **circle()** as well since I haven’t installed 3.5.1 yet to confirm it) use radius in place of diameter for both its _width_ & _height_ by calling `ellipseMode(RADIUS);`: 🔘

**A small warning:** if we intend to have our Java Mode sketch to automatically transpile to JS via Pjs, we should avoid both **circle()** & **square()** completely! 😿

Circle and square have been added to the reference.

- [https://processing.org/reference/square\_.html](https://processing.org/reference/square_.html)
- [https://processing.org/reference/circle\_.html](https://processing.org/reference/circle_.html)

…and yes, it looks like the arguments / render style for circle and square are controlled by ellipseMode() and rectMode(), just as with ellipse and rect.
