Transformation of a 3D object based on specified words

in Programming Questions • 2 years ago

Hello,

I am new to processing and I really need some help. I would highly appreciate it if you could give me a clue on which direction I need to take or which is the best way to implement my idea.

I want to start with a 3D object (let's say a cube) and have the program change the values/parameters (width of base, width of top, height, orientation, new points/curves along the surfaces) based on the word content of a loaded text file. I want the program to detect specified in the code words.

If (the word “more” is used within the text) {
Increase the width of the cube}
if (the word “time” is used within the text) {
Rotate the object 20 degrees to the left}
If (the word “smooth” is used within the text) {
Flatten the edges of the shape by 1}
…and more
Basically, I want to have the cube transform into any another object (cylinder, cone, conical frustum etc) based on the presence of specified words in the text file.

I tried the following way: put a random text in a txt file and loaded the file in Processing

lines = loadStrings("story.txt");
…
for (int i = 0; i < lines.length; i++) {
if (lines[i].equals("love")==true) {

println("love");
fill(255, 0, 0);
rect(width/4, height/4, width/2, height/2);
}

However, I had to separate each word into a line in order for the program to read every word. I need the program to consider all the words without me having to separate them into lines.

Thank you so much for your help!!

Most people use a certain character to separate individual items, such as " ," or " ;". If you separate the words like so:

blah;blah;blah;more blah;
etc.;blah;more!;more!

using the " ;" separator, you can then use split() to split each line into the words separated by the semicolons.
You then concatenate all of the arrays formed by the lines into one and then do your for loop.

If you want the text file to read more like English, you could use splitTokens() (which takes an array of tokens) and pass an array of, say, " ", " \n", " .", " ,", etc.

Also, in line if (lines[i].equals("love")==true) {,
you just need if (lines[i].equals("love")) { - the == is unnecessary.

Hi,

And thank you for taking the time to answer my question! Unfortunately, the program still does not tell me "Yes, I found the word you are looking for and it appears x times within the text"

I tried the splitTokens() function:

String[] lines = splitTokens(" ");

void setup() {

size(400, 400);
background(255);
lines = loadStrings("story.txt");
}

void draw() {

noLoop();

for (int i = 0; i < lines.length; i++) {
   if (lines[i].equals("love")) {
       println("love");
      fill(255, 0, 0);
      rect(width/4, height/4, width/2, height/2);
    }
}
}

The text file will be always a rather long text of a story and it may be difficult to go through it and separate all the words with ";"

There is no way the program can go through a chunk of 1000 words text and tell me: "I found the word "love" appears 5 times"?

Thanks so much for your help!

You are assigning lines to the split of " ", which is just "" and then reassigning it to the loaded text file.
