    • ???
  • Opera 12.1+ (tested)
    • Not functionnal
    • WebGL: perhaps requires activation in the browser settings (opera:config)
    • No unload event
    • No FileSaver API
  • Take 3 pictures: front / right / left
    • Choose a facial expression and keep it for all pictures
    • Also keep constant your digital camera settings (this is important for modeler correpondance)
      • Use the same zoom level
      • Use the same shooting distance
      • Use the same focus
    • Take care of the light:
      • Prefer daylight rather than artificial light
      • This is not the subject that rotates but the camera that moves !
      • Light from the front rather than the back to avoid shadows
  • Open the online picture-based head modeler
  • Set each picture
    • From an image file or webcam capture
    • Orientate and crop to keep only the useful part as shown in pictogram
  • Model
    • Global mode: adjust and position global model or subsets
    • Vertex mode: deform model
    • Right-click to adjust brightness between pictures
  • Get the 3D puzzle
    • Simply click on '3D puzzle' button
    • or save your project and open it in 3D puzzle

Animated avatar

  • You can get animated avatar from the online head modeler or any external filebeta (.dae/.zip/.kmz)
  • Once opened, orient, zoom the model as it should be on the first frame of animation
  • Fill the GIF parameters form, mainly the desired avatar size
  • Right-click and save your GIF image

External 3D model

You can use .dae, .zip or .kmz files (collada format).
Here is some interesting links:

Embedding viewer HTML

  • Right-click any 3D viewer and select 'export HTML'
  • For a quick integration just paste the viewer code in the BODY section of your site or blog page
  • May be you could split HTML HEAD and BODY part for a clean integration
  • The code use jquery library and the '$' as jQuery alias. If you have another library that use the '$' you should see and use jQuery.noConflict method

Getting a 3D puzzle

  • Load your model in 3D puzzle
  • Check carefully that its rendering is ok: unfortunately, most 3D modeling tools, in particular CAD tools, pay little attention to consistent normal orientation and thus black faces can appear. You should use your favorite model editor to correct that before continuing
  • Select your favorite working unit
  • Adjust the scale factor to get the expected paper model size: see bounding box information which gives a good idea of the size you will obtain
  • If needed, reduce mesh complexity to enhance the following points
    • Small edges are difficult to handle with big fingers
    • Too many triangles leads to many working hours
  • Force 'no texture' option if you want to get a 'blank' model that you will be able to paint and personnalize
  • Set your printer output paper format
  • Give your address email to receive your PDF file
  • Once again, before submitting your order, check if:
    • The paper model size (see bounding box) is the one you expect or adjust the scale factor
    • The number of triangles is reasonable or reduce it using mesh simplification
    • The size of parts is not too small to be easily handled (see smallest edge length)

Printing

  • Just use your own home printer
  • Paper density should not be lower than 80g/m² for having a good rigidity
  • Notice the default margins inserted in the PDF file are (top:10, right:8, bottom:10, left:8 in millimeters) which will be ok for the majority of printers. Take care to override those in your printer parameters if needed
  • For better quality or a bigger format you can use online printers

Cutting

  • Needed equipments
    • (comfortable) scissors
    • A light source (optional)
  • Be patient, accurate and applied, carefully cut all the pieces
  • Tips
    • A perpendicular light can help to clearly see the cutting area

Folding

  • Needed equipments
    • A rigid ruler
    • Tweezers
    • A light source (optional)
  • Once again be patient, accurate and applied, carefully fold
  • Using the ruler, mark the folds according to the dashed lines:
    • Long dashed lines must be fold as a hill (the ruler behind the paper)
    • Short dashed lines must be fold as a valley (the ruler in front of the paper)
  • All tabs must be fold as a 90° hill
  • Fold using the finger
  • Permanently mark the folds with the nail or tweezers
  • Tips
    • Use a light to see by transparency through the paper and position the ruler

Assembling

  • Needed equipments
    • Some glue (a stick is convenient)
    • A small stapler
    • Tweezers
  • Once again be patient, accurate and applied, carefully assemble the parts
  • Each index must be assembled with its double
  • Start with the smallest pieces and edges (eg the eyes and the nose for a head)
  • Stick tabs together: use tweezers to ensure accuracy
  • Staple if needed
  • Tips
    • Start to assemble the smallest tabs
    • Glue is mandatory to obtain a rigid object from classic paper
    • Plan to finish by the most accessible and largest pieces

3D printing

  • Open a 3D model
  • Check and adjust carefully the scale factor (keep in mind that 3D printing is still not cheap and the cost is proportional to the model volume, so prefer small sizes, they are more affordable)
  • Export to a 3D printer generating a collada file
  • If you do not have your own device, go on an online 3D printer, for example:
  • Load your collada file
    • Choose 'meter' as unit
    • Choose a material
      • Note that most materials give solid color
      • Use 'full color sandstone' for textured models
    • Place your order !
