That feeling when you're fine, but actually you're not, because what you actually are is hollow and it's like every time you talk to people, your words are just the surface of a shell around an empty desperation, and you're not sure which self is more true. #micropoetry
![A screenshot of the "Scripting" workspace in Blender 5.2.0, showing the interactive Python Console, where the following two lines of code were just run:
for vertex in bpy.data.objects['Grid'].data.vertices:
vertex.co.z = sin(vertex.co.x)
Note: You can also combine functions and/or use different coordinates (multiplying the sin of the x coordinates by the cos of the y coordinates, for example). Have fun and experiment!
Below the Console is a 3D Viewport where the mesh grid now resembles a sine wave; to the right is the Text Editor, displaying the following text and code examples:
# Don't forget to 'import bpy' and any other necessary modules (like math) if running scripts from Blender's Text Editor or when using Blender from the command line. If using its interactive Python Console, the bpy module is already available.
# Also, because of the Console's "Convenience Variables" for bpy's context and data hierarchies, the code to the left could also be written there as follows:
for vertex in D.objects['Grid'].data.vertices:
vertex.co.z = sin(vertex.co.x)
# Again, keep in mind that the 'C' and 'D' variables are just shortcuts. If you want to use them in scripts outside of Blender's Python Console, you have to define them yourself.
# Extra Credit:
# An object is not the same as its mesh. A mesh technically lives in its own branch of the bpy.data hierarchy; each mesh can be linked to one or more objects. In this case, the 'Grid' object and the 'Grid' mesh happen to share the same name, but they don't necessarily have to.
# In the code example(s) shown here, the '.data' of the 'Grid' object refers to the mesh data that it's linked to (different object types have different kinds of data), and the vertices belong to the mesh. We could therefore also have written the code this way instead, addressing the mesh directly:
for vertex in bpy.data.meshes['Grid'].vertices:
vertex.co.z = sin(vertex.co.x)](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:kpbtlvjduvli2tl62zyinhex/bafkreif5csh4vtqwhfvinhzpkju6eij4k7nobitiaejogjbxrtjrpiyuaa)
