Parametric Design Grasshopper Tutorial 2 | Class 2 | Creating a Wavy Surface with Image Sampler 

In this tutorial, you'll learn how to use the "Image Sampler" component in Grasshopper to interpolate a wavy surface based on image data. Import an image into the Image Sampler and extract its grayscale or color values, using these as control points for the Z-axis displacement. The sampled values will dynamically influence the surface, creating a wavy, undulating form that reflects the tonal variations of the image. By leveraging this technique, you can create complex, organic surfaces driven by visual data, adding a new level of responsiveness to your parametric designs.
