Grasshopper 101: Data Filtering | #05 Filter Mesh Vertices | EXERCISE

EXERCISE: In this tutorial, we practice using Conditional and Logical Operators for Data Filtering. We learn how to create a mesh surface, based on the NURBS surface, and revise the concepts of data construction and deconstruction in Grasshopper This video is an introductory tutorial for beginners. CHAPTERS: 00:00 Intro 00:45 Creating NURBS surface from corner points 01:00 Create Free-Form NURBS surface using Control Point modeling. 01:37 Reference the NURBS surface from Rhino to Grasshopper. 02:05 Create Mesh Surface from NURBS surface. 03:03 UV inputs to control mesh surface topology. 03:18 Mesh Surface from Trimmed NURBS Surface | the Overhang input 04:03 Equalize Mesh Surface edges | the Equalize input 05:10 Deconstruct Mesh to extract its vertices. 06:00 Deconstruct mesh vertices to extract their coordinates. 06:19 Comparing values with Conditional Operators | Smaller Than 06:50 Finding the Bounds of numerical values. 07:50 Filter mesh vertices using Cull Pattern component. 08:12 Assigning custom preview colors to filtered lists. 08:25 Comparing values with Conditional Operators | Larger Than 09:25 Comparing values with Conditional Operators | Smaller Than 09:53 Combine boolean results with the Gate And logical operator. 11:30 Organizing Grasshopper definition on the Canvas. 12:06 Closing COMPONENTS: Mesh Surface Deconstruct Mesh Deconstruct (Point) Bounds Smaller Than Larger Than Gate And Cull Pattern PREREQUISITE TUTORIALS: EXERCISE 01.A Mesh Color | https://youtu.be/F-OTuaRHBxc LINKS: Add-ons: https://www.food4rhino.com/ Forum: https://discourse.mcneel.com/ Grasshopper component library: http://grasshopperdocs.com/ CONTACT US AT: https://www.learn-visual-programming.com Narrated by: Lina Vestarte _ Click LIKE, if you find the tutorial useful.
