Rules :
1. Any type of paper can be used.
2. Participants are allowed to paint and glue models if it
would not prevent identification of all elements of the
model ( including pre-creased lines defining the
assembly process). This rule does not apply to the
participant’s own design.
3. Only photos never published before the olympiad are
allowed.
4. Each model should be photographed from at least three
angles to clearly display all the details. Low quality
photos will not be considered, but total size of the
resulting message should not exceed 10 Mb.
Recommended size of pictures is from 480x480 to
1500x1500 pixels.
5. Minimal editing of the pictures is allowed as long as it
doesn't affect the appearance of the model. E.g. you can
crop photos, reduce the noise, change color balance
but you must not add, erase or change any details.
6. Participants should not upload photos of their models
to the Internet before the end of the Olympiad.
7. Send your results before 15.11.2014 to
