Cedrick Wiley: Laser engraving

The way that laser cutting or engraving is done is by assigning colors in certain file formats. This provides a different intensities causing for a lighter or darker lines on the surface of what ever material it may be.

I used my illustration also my logo. Then I entered it into Adobe Illustrator. To separate layers by manipulating the layers and image trace setting. To make the lines coincide with the desired illusion of depth by using the lasers intensity levels. The red lines emit a shallow line. The green lines emit a higher intensity than the red so it would qualify as the mid-tone or medium value line. The yellow line emits the most intense line or value meaning it cuts the deepest in to the surface plane.

I was instructed by the technician that are over the laser engraver. That the complexity of the illustration would cause the laser to take 5 to 6 hours to complete the task. So they advised me to use different values of black as a substitute for the value change that is done by the laser recognizing the differences. Not what I was hoping for but due to time restraints I followed there instructions.

Here is a better example of the separation of line and value. Concerning how lasers separate and define the intensity below.

Here is the results through the process. You can see how the lines are defined differently with the addition to color separation.

Cedrick Wiley: Hand modeling to 3d modeling process

Hand sculpted a humanoid figure. With modeling clay the dots are for preparation for the 3d scan. The registration dots are to align during the 3d scanning and editing process because of the multiple scan.

The next image is of the scanned sculpture. The program it was placed in was for altering and correcting any issue the 3d scanner may have missed.

The following image is in preparation Pepakura. It is necessary to lower polygon count in the 3d software. The image is less complex and flatter intentionally to make the use of Pepakura effective.

I was not pleased with the resolution and dimensions. I was becoming more familiar with the 3d software so I was confident enough that I could get a better structure and still take advantage of Pepakura's software.

I was more comfortable spending time constructing a model without a scan. Hoping for a better result.I was pleased with the direction the model was going in for preparation for Pepakura I attempted to lower the polygons. I was unsuccessful the model did not allow me to lower the polygonal faces. Which didnt allow me to use it in Pepakura.

I attempted a few other models. Due to time restraints I used the Pepakura model for the original model scan. Below this is the proper way and what a Pepakura flattening of a 3d file looks like.
