 | Open the model you created in Part 2 of this Tutorial or click here to
download the sample model.
Double click the object to open it in the Surface Tool. |

 |
 | We will now be working on the full dinosaur head so we will need to use an uncropped
version of the image.
Click here
to download the full image.
Click on
the main toolbar to select the uncropped image of the dinosaur.
Alt-Select the head. This will select all of the surfaces that make up the head. |
|
 |
 | Scale and move the head so that is positioned over the image. |
|
 |
 | Add the sails. These are simply surfaces added and deformed in the same way as in the
previous tutorials.
These surfaces should bet linked to each other, but should not be linked to the main
object in any way. |
|
 |
 | Add the horns. Again, these are just surfaces added and deformed in the same way as in
the previous tutorials. To make the tips of the the horns simply place all four edge
control points in a single location.
The horns should not be linked to each other, the sails, or the main object.
Add depth to the horns. Also add a very small amount of depth the the sails. |
|
 |
 | We have now completed the modeling phase. |
|
 |
 | When we divided surfaces, we created uneven sized surfaces.
If you wish you can divide further surfaces to ensure a more equal distribution of points
on the final model. |
|
 |
 | We can now start merging surfaces.
Merging surfaces is not required, but will result in a smoother model with much fewer
creasing problems.
We'll start with the sails. Click on a surface, click , and then click the neighboring
surface. This will merge the surfaces. |
|
 |
 | Surfaces can be merged vertically as well as horizontally. As long as they share an edge
and their control points are linked, they can be merged. |
|
 |
 | Merge the surfaces of the head horizontally first. |
|
 |
 | Now merge the surfaces vertically until there is a single surface.
Do not merge horns or sails with each other. Only surfaces that make up what could be
considered a single unit should be merged. |
|
 |
 | Mirror by clicking .
Click on the right side of the face and then merge with the left side of the face. This
will smooth the nose and create a contiguous surface for the head. Note that these two
surfaces were actually linked to each other on all four edges. In the case where surfaces
meet on more than one edge, 3D Canvas prioritizes based on which surface is clicked first
during the merge. If you are not happy with where the merge occurred, simply undo and
merge in the opposite order.
Merge the left and right sides of the horns also. Do not do this for the sails as this
will result in unacceptable results.
In this example, I vertically divided the head surface and re-merged in order to even out
the size of the surfaces which were too wide.
Close the Surface Tool. |

 |
 | Here is our completed dinosaur head.
As a final step, I scaled the head since it was a little too narrow. I also applied the
Crease
operation to adjust the creasing of the head.
