Introduction : Introduction to Landscape Modeling Welcome to our project on landscape modeling! Today, we will explore how to create a realistic landscape model using both digital tools like Tinkercad and physical materials. Our goal is to recreate a mountain scene with a bridge and river, similar to the image shown. We’ll start by sketching our ideas, then move on to digital modeling in Tinkercad, and finally, build a physical model. This process will help us understand the principles of landscape design and the practical aspects of constructing a model. Marking Rubric for Project 4 : Landscape
