Getting started

 
 

Introduction

There is no getting around it, creating blipps is a complicated process. You need markers and many different aspects that all need to be brought together and uploaded onto the Blippar server for use.

The typical requirements for a blipp are:

  • Marker image(s)
  • 3D models
  • Textures
  • Sound files
  • JavaScript code

These different files require different applications to create and edit them.


 
 

Using image editors to create markers and textures

 
 
Typically people will use an image editor such as Abobe Photoshop to generate their markers and textures.
 
 

Creating a Marker

The marker is the most important part of your blipp. A poor choice of marker will make the blipp hard to detect or undetectable at all, it could also make the blipp jitter, or perform poorly as the tracked object is moved around.

  • A marker should have the following characteristics:
  • A jpeg (.jpg) image
  • High contrast, with as many sharp crisp edges and corners in the image as possible.
  • A good spread of features across the whole marker. A marker with all the detail at the bottom and none at the top may not track well.
  • A size measured in 100s of pixels. A good size is around 800 x 600 for a page-based marker. Do not create markers of huge resolution. Larger sizes will not improve tracking and will slow down server uploads.

Tip: Changes in colour are not the same as high contrast. Convert your marker to greyscale and see if has good characteristics as listed above.


 
 

Creating Textures

Textures used on 3D objects by blippar must have the following characteristics:

  • jpeg (.jpg) or PNG (.png 32, 24 or 8) images
  • Width and height that are multiples of 2. I.e any of the following: 8, 16, 32, 64, 128, 256, 512, 1024, 2048. Non-multiples of 2 are allowed, but the App will scale up images to the nearest power of two.
  • Not smaller than 8 pixels in width or height
