In this session we're reproducing Christos Stavridis' beautiful Hexagona project but we're using the new Geometry Nodes with its fields system to do it!
I glossed over a lot of the finer points of fields in this session but I will do some more specific videos on them. I thought it would be fun to just jump straight into a project with this!

For anyone having issues with centering the hexagons/There's no tick on the offset; Take the Vector output of your multiply just before your first Set Position and plug it into the Offset of the second Set Position. No idea why it works, it just does.

The position socket is for explicitly defining the position and the offset socket is for adding a vector to the existing position.

Best way is to add another geo nodes modifier and add a Distribute Points on Faces node. Use a Normal node and put it through a Vector math node set to Dot Product and the second vector should be (0,0,1). Use a Compare Floats on the output and where plug the output into the selection socket of the distribute node. The float compare will lot you set how close to your input vector it gets masked.

Height map colour will just go through a subtraction for mid-level, multiply for strength and then that sets the height. The only thing to set up different is the vector input to map the image. Easiest way is to take a position input node into a vector map range. Then use a bounding box node on your whole grid to get the min max for the from min, from max, of the map range. To min/Max will be (0,0,0) and (1,1,1) as a full UV area and then that plugs into your image texture node

This is such a neat tutorial! I have a dumb question though. I am pretty new to geometry nodes (and I am not an experienced blender artist but want to learn more). In your geometry node shader graph some of the nodes connections are done with solid lines and some are done with dashed lines, is this just a change you have made to your settings or do the connections mean something different when the lines are dashed versus solid? Sorry if this was explained in a previous video.

Okay admittingly I was still in the middle of watching when I wrote this question, he doesn't know but if someone else knows that would still be cool to be told!
@Erindale 2 жыл бұрын
So a dashed line has a field in it like Position or Index or Normal etc. Solid lines are constants like on the bounding box node outputs. A field is just different because it gets specifically computed for every mesh element (normally vertices).

Still enjoying playing about with this set up. Been wondering if in 3.1 alpha there might be a way to colourise the instances procedurally? I can grab an 'Object Info' node in the material editor, plug random into a 'ColorRamp' and pass that to the base color and it colourises each instance randomly from the ColorRamp. There are other sockets on the 'Object Info' node but I really can't work out how to pass indexes ordered by height to it or the Attribute node.
@Erindale 2 жыл бұрын
It's a bit of a chore but you can pass an attribute to instances. We should be getting some specific nodes though for doing it in a more streamlined way though!

I think there's a grease pencil thing that lets you trace an image? You'd then be able to convert that to a mesh! Until we get the image texture node I won't be able to do any testing on that in geo nodes

@@Erindale on my off days I plan to go through the stunning art creation on your procedurally node-created bridge. No success with RenderDoc and then I realized I may just have to cough up the courage to model everything after all. Anyway, i know how to use grease pencil and classical modeling over images in the viewport the old school way...but I want to simply my workflow by taking an image, like a tif, into the scene on a uv mapped texture/material and use this to extrude geometry from non transparent pixels, rather than hard modeling so many lines for hours an hours on end, for multiple iterations of a project's lifecycle. Can't we drive the z value with a manual value or extrusion after we get the XY points of non transparency (very low res) hook them to a geo-node for dot products including all points not z and not alpha hooked to an instance which is a vertex group? Connecting the lines would be possible with some python and scripting, but I am feeling like this could already be possible with simple procedural nodes.. Or some other mathy thing. Basically, sampling a texture would not drive many instances like voxels, but rather one instance of verticies which maps the path of the line/faces to the geometry data of the sampled image. Maybe it's not quite possible in blender... Yet. I would think with all the functionality there would be a way to convert line work in a simple two-tone image into verticies that connect simple lines. 🤔

You can make a hexagon of hexagons by starting with a line converted to points for an index as you did, and then instancing a curve circle with six segments scaled to the ID plus 1 all at 0,0,0, so you get a set of concentric hexagons. Then you realise the instances, do a curve to points based on length (for some reason, I've found it necessary for the length to be very slightly longer than the radius, like, 1.001x) and instance hexagons on the points. No need to make a wobbly grid or worry about the 1.73/0.866/0.43 issue or make a mask using the dot product. All those numbers are related, btw. 0.866 is half the square root of three, but it's also the sine of 60 degrees, which is why it and numbers relating to it keep popping up when you're using triangular or hexagonal grids.

@@wanderingturtle1705 Hm. Hard to do without screenshots. Basically, add a curve primitive: line. Convert it to as many points as you want concentric hexagons using the "curve to points" node using the "count" parameter. Then put that into a "set position" node, and plug a vector of 0,0,0 into the "position" socket so all the points are centred. Then create a curve primitive: circle, and make it a hexagon by giving it six sides. Then, do an "instance on points" using the hexagon as the thing being instanced, and plug the "scale" socket into an input: ID and a math node that adds 1 to that value. Now you have a set of concentric hexagons. Now, do another curve to points with that, and this time use the "length" parameter instead of the "count" one, and enter a value of very slightly over 1 into the dialog box. Hey presto. You have a set of points in a tessellating hexagonal pattern that you can us to instance hexagons, or anything else you want in that pattern. Triangles also work, but you have to rotate some of them.

Great video! I have a question. Is it possible to manipulate individual hexagons in this system, like for instance making a "pathway" where the hexagons are the same height in a path so to speak?
@Erindale Жыл бұрын
You certainly could! You can make a selection in several ways, for a path the most logical way would be to use Geometry Proximity and a spline and then you can use a compare node to find hexagons that are less than some distance from the spline and define their heights separately (eg with maths or a switch node)

Loved this tutorial, great to see the new system. I'm having fun playing with the hexagon world. One question, using the 3.0 beta, the bevel modifier only affected the 'sea' hexagon, not the instanced hexagons from the collection. I ended up having to add a bevel modifier to the cylinders themselves. Did I miss something?
@Erindale 2 жыл бұрын
I think this changed the day after I recorded it 😅 You now need to stick a Realise Instances node at the end and you'll be able to bevel. But, like in my case, realising instances makes things run a bit slower. Especially when there were a lot of instances.
