These excerpts appear to be from two parts of a workshop or lecture focused on data structures in design, specifically pixels and voxels. The instructor guides participants through Python code examples illustrating how to create and manipulate pixel and voxel grids, including concepts like connectivity, smoothing, and query operations based on location or data values. The material extends to demonstrating these concepts within Grasshopper 3D software, showing how to visualize and interact with the created grids. Additionally, the sources touch upon image processing techniques and their application in design contexts, highlighting concepts such as color blending, filtering, and spatial analysis using elevation or environmental data. https://namjulee.github.io/njs-lab-public/work?id=2025-introductionToDesignComputation 6z3n20
