Hi,

 

I've attempted to load an .OBJ file generated from MCOBJ into Processing, but get array out of bound errors. 

 

It could be due to an issue with the format of the file or limitations of the Library or both, but I don't know where to look first.  I've successfully run examples from the library and created very simple OBJ files to load into processing, so I know it works, but I've also managed to load the same OBJ file into Blender, so I know the file isn't corrupted.

 

I'm not sure if I'm trying to do the impossible.  Is there a limit on the OBJ file size imported into Processing?  Alternatively, is there some things the Library is not designed to cope with?

 

Has anyone else tried doing the same?  Any advice appreciated.

 

 

Some example code would be great to allow me to extract & convert a date into a string from these values.

What is the cleanest and most efficient way of determining the number of boolean values set to 1 in an array of objects?

I have an array of objects that have a boolean value which determines whether the object (a node) should be displayed to the screen.  I want to determine the total number of objects that should be displayed. In other words, all the objects with the boolean variable 'display' equal to 1.

1. int total;
2. 
   
3. for (int i = 0; i < node.length; i++) {
4.   if (node[i].display.equals(1)) {
5.     total++;  
6.   }
7. }

Can this be done in one line with an array function rather than using a loop?

I have the following code that's adapted from an online example for rotating text. The code works fine in that it rotates the text to the correct angle, but I would like to know if there is a way to improve the anti-aliasing of the rotated text. On my display it looks as though the rotated text is not anti-aliased despite selecting 'true' when creating the font.

1. String message = "abcdefghijklmnopqrstuvwxyz";
2. float theta, x;
3. 
   
4. void setup() {
5.   size(800, 200);
6.   f = createFont("Arial",20,true);
7. }
8. 
   
9. void draw() { 
10.  // background(255);
11.   fill(0);
12.   textFont(f);    // Set the font
13.   translate(x,height/2);  // Translate to the center
14.   rotate(theta);                // Rotate by theta
15.   textAlign(LEFT);            
16.   text(message,0,0);            
17.   theta += 0.1;                // Increase rotation
18.   x += textWidth(message);
19.   if (x>800){noLoop(); }
20. }
