hi

having trawled through Discourse + tried to make sense of the libraries documentation.

How do I make an L shaped shape - & not by simply placing some boxes together.

These will be parts of a bitmap style typeface being extruded into 3D.

By hacking the Picking example supplied with the shape3d library I can create a grid of 'box pixels', but I'd like to end up with the actual shapes of the letterforms.

Any help here much appreciated

You might also look at these 2 examples.

Since you are using a bitmap font then putting boxes together might be a solution the following code shows how it might be done quite 'neatly'
Code:

import shapes3d.utils.*;
import shapes3d.animation.*;
import shapes3d.*;

import peasy.*;

Anchor letterL;
Box sL1, sL2;

PeasyCam pcam;

void setup(){
  size(300,300,P3D);

  letterL = createLetterL();

  pcam =new PeasyCam(this,200);
}

void draw(){
  background(0);

  letterL.draw();
}

Anchor createLetterL(){
  Anchor anc;
  Box sL1, sL2;

  anc = new Anchor(this);
  sL1 = new Box(this, 20,100,16);
  sL1.shapeOrientation( null,
    new PVector(sL1.getWidth()/2, -sL1.getHeight()/2,0));

  sL2 = new Box(this, 50,20,16);
  sL2.shapeOrientation( null,
    new PVector(sL1.getWidth()+sL2.getWidth()/2, -sL2.getHeight()/2,0));
  anc.addShape(sL1);
  anc.addShape(sL2);

  return anc;
}

great stuff

I started working with the shapes3d library cause it looked the easiest

I've now got a 3D boxes version working

while its quite nice in a way to go from pixels to boxes

I'm still after extruding the letterforms

--

exported cube from blender into Processing via FluidForms lib

will experiment some more

and thanks for all the help

hi

cool


status

I have 3D text made out of boxes via shapes3d library

generated from the arrays I put together for the 2D prototype

this uses peasycam so 3D text object can be moved about by user

then adding the fluidforms lib 3D object becomes very hard to get hold of & the generated STL file isnt getting any results in Blender.


Exported a STL from the non extruded custom shapes sketch I started with

this imports into Blender but shapes are all screwy  - as in the + of a letter t has the corners replaced with diagonals
and letters like 'o' which I made out of 2 seperate shapes just turns into solid shape

so some way still to go...


& thanks again to everyone for pionters to resources etc
