How do you create a triangle pattern in a plane?

Question

I want to create this picture, except going on for the entire plane, and just the geometry, not with multiple shapes. Is there a way to do this? (not with the going over lines)

Hello :). Do you mean a triangulated plane or a texture? What have you tried so far? — jachym michal, Mar 24 '21 at 21:28
I meant the geometry of the plane, so if I moved a vert and had proportional editing on, the surface would be a lot of triangles like a hill — Clobro, Mar 24 '21 at 21:33
Perhaps related: How do I stack triangles into a bigger triangle with array modifier? — jachym michal, Mar 24 '21 at 21:41
no, like the triangles are in the plane without anything changing — Clobro, Mar 24 '21 at 21:56

The fastest way I can think of is to divide a plane into 2 triangles first (e.g. select opposite corner vertices and press J), then select both and subdivide.

You can also use Subdivision Surface + Triangulate modifiers:

This is probably the closest you will get to triangles. In the picture you shared, a square is impossible, so it will never fit the mesh right. – Relevred Mar 24 '21 at 21:47
What about a hexagon plane? – Clobro Mar 24 '21 at 21:57
@Clobro I don't have time for a full answer but: add a circle with 6 sides, in edit mode, extrude but don't move vertices. scale to 0 and weld, you now have one hexagon. Use the array modifier to make as many as you need. – Ron Jensen Mar 24 '21 at 22:07

Just to add to Markus von Broady's answer:

Shear the result by -0,5
Scale by √75 (0,8660254...)
Done

Tadaa...

Might've missed something, but the triangles come equilateral at my end :). – jachym michal Mar 24 '21 at 23:06
can i have the blend please :) – Clobro Mar 24 '21 at 23:08

Or you could rotate an edge 60°, make a face and subdivide that :) https://i.imgur.com/JHHxkpW.gif – Markus von Broady Mar 24 '21 at 23:31

@Markus Now that's just stupidly simple. Or add a circle with 3 sides. Aaargh... :D – jachym michal Mar 24 '21 at 23:34
oh i am so bad at blender – Clobro Mar 24 '21 at 23:57

Instead of typing 0.8660254 into the y-scale filed, just type sqrt(0.75). Blender will evaluate simple Python expressions like that for you :) – maddin45 Mar 25 '21 at 12:05
@maddin45 Thanks, i'll edit it in :). Tried it with the √ symbol before, but Blender got confused :). – jachym michal Mar 25 '21 at 12:35
