Plant structure study

I have created this software process that generates random organic structures with vegetal appearance.

Nature and biology always inspire me. That is why I have been taking photos of flowers for so many years.

Vegetal structures look very interesting to me. I like to analyse them from a mathematical point of view so I can regenerate them in the computer. Also I wanted to provide a clean, ethereal look to these. I want them to bring you harmony and peace. In the final result I am not looking for replicating hundred percent the reality. Instead I use these structures as inspiration in order to build something I appreciate as beautiful. I like that the maths can be observed in the final piece.

I want to encourage anyone seeing my works to appreciate the beauty of nature and maths when they coexist.

In order to create them, I made extensive use of trigonometry and vectors.

The output is resolution independent resulting in great flexibility.

Made with Processing and Photoshop.

How to call to a static method passing a function so it is executed?

Hello all:

I have a static class with a static method that I want to pass a function to (similar to javascript way) but Java doesn't allow this.

How would you go about it?

Caller function (in my main file):
1. void keyPressed() {
2. //how do I pass create here?
3. StartManager.startOnKeyPress(this);
4. }
The function I want to call to is also in the main file, something like....
1. void create() {
2. background(0);
4. //do other cool stuff here
5. //....
6. }
And here is the callee class. I don't know how tell it "ey, call the create function of the main file":
1. static class StartManager {
3. static void startOnKeyPress(PApplet context) {
4. if (context.keyCode==69) {
5. //here is where I don't know how to call to create of the main file
6. create();
7. }
8. }
9. }
I have found in stackoverflow that you can use something like a Callable interface, but I don't know how to apply this here; example:
1. ```
dansMethod(100, new Callable<Integer>() { public Integer call() { return methodToPass(); } });
```
Many thanks in advance for your help.

creating vectorial masks without geomerative?

Hello all:

I want to make a very simple thing. Create a square and rotate it 45 degrees and then mask it with another square.. .

I don't want to do it using PImages or raster images in general; I want it to be purely vectorial (for PDF export not containing images), and only using rect()

How can I do this? I have seen a way to do it with the geomerative library but the result is broken when you magnify it.

The toxi library apparently has also something (SutherlandHodgemanClipper). Does processing include something natively to do this kind of tasks? In actionscript 3 was super easy to create advanced masks not only with bitmaps!

Couldn't find it here in the forum or in the processing documentation!

Thanks a lot

clearing the screen without calling to background() for PDF export

Hello all:

I always use background(value) to clear the screen before generating a new execution of my algorithm, animation, etc.

The problem is that I don't know how to clear the screen without using background(value) and I couldn't find any way to do it in this forum or google.

The reason why I want to avoid using background(value) is that I want to export several PDF files with transparent background.

When I don't call to background(value) this happens: the PDF gets exported without background (as I want).

Any advice?

Thanks in advance for your reply.

Hi!

I couldn't find an answer to this.

Let's suppose I want to do always the same things inside of my keyPressed handler and, therefore, I want to share the code inside of the handler among sketches:

void keyPressed() {

if (keyCode==32) {

//do always same stuff

}

}

what would be the best way do do this? create a class with a static method an put it inside of the libraries folder?

thanks a lot in advance!

exporting to tif format with layers

Hello; I´ve been trying to find a solution for this question before asking.

I have a couple of interesting algoritms and I want to print them out. Everything is fine, I can currently export png with transparency, which is really nice.

But I was wondering if is possible to export a tiff file with layers, so I can open it in photoshop.

The idea is to say, layer 1 = PImage1, layer2 = PImage2 and so on.

Thanks a lot!
