T-Splines software must be used at some point in your model creation.
  2. Render(s): Include a final render of the model. You may optionally include up to five renders.
    • To ensure unbiased judging, design files should not have your name or any indication of identity visible.
    • If you want credits on your images, please attach a separate file with your signature displayed on the lower right corner of the image.
  3. Explanation: Write up an explanation of how you modeled your design, explaining the software used to model and render your design and why T-Splines was useful in the process. 700 words maximum.

*Each design entered will need to fill out a separate submission.
