Endless Flight Loop with Geometry Nodes - Blender Tutorial

[@tiagotiagot]

To keep the elevation lines at a more constant thickness, you can do it like this: Less-Than-Threshold = ColorInvert( Desired-Threshold ) * ColorInvert( DotProduct( Normal, ) )

[@rbettsx]

I think one of the answers to Blender Stack Exchange ( search 211883) gives a more exact contour-thickness? Basically arccos of the same ... for constant angle on the spherical approximation of the surface (Dot 0,0,1 is just N.z.. N is normalized)

Loved to do this tutorial...(and others from ErinDoes) because I learned a lot and enjoyed the style he used... but the best is the way how he explains maths translated to nodes and then in graphs.... I can now say to my maths teachers that I understood all the stuff they tried in the past. Nothing like a graph to understand most of maths in a visual way. Difficult to synthetize that and translate in a 3D world. You are amazing!

[@TommyLikeTom]

instead of ray casting to get the ship's height you could just use the same noise setup with less detail and offset it by a little bit. Works great. Honestly the limitation of the node based system just makes me want to code. The lack of access to previous frames, the lack of loops. It is nice to learn though

[@Erindale]

You could! Even clamping it or squeezing in with a float curve to make it just rise for the peaks

[@TommyLikeTom]

It's easy to create pitch controls. Just duplicate the altitude raycast, move it back, subtract from the original, and angle the craft along the Y axis using it. I also made the plane slow down and speed up. It's actually a lot of fun to change the landscape to see how the plane reacts. Great game.

Love and learnt a lot from your tutorials. Wouldn't it be a bit easier to compare the z-value of the position > 0 the get the height only on the top of the cube instead of normal dot product?

[@Erindale]

In this case yes but the dot product method will work for any vectors you choose to compare so much more flexible to know! Eg you can use the edge vertices node subtract the verts from each other, normalise, then dot product, then absolute and you're now able to select by edge direction 👌

[@BlenderFun_]

@@Erindale yeah, you are absolutely right

[@KDawg5000]

For the angle of the plane, I think you had your subtract swapped, because the wing would raise in the direction it moved sideways, which is backwards. However, in your clip at the very end it seems you had corrected it. Also, when I used an object input for my plane vs. the cube, the Vector Rotate didn't work. I ended up plugging the rotate value right into the Rotation spot on the Transform node and it worked well. I'll post my results on Twitter & here once I render it. Thanks for the great tutorial!

[@Erindale]

Yeah you're right. In the video I added some text to say sample in a positive direction and that's what fixes the banking for me. It also allows you to bank and then move into the turn which feels more natural. Strange the vector rotate didn't work for you but glad you got a workaround!

The capture node now works a bit easier. Just select the domain you want to capture on and plug in whatever values you want to capture at that point. Now you can capture multiple attributes at the same time as long as you want them on the same geometry domain.

If you’re replacing the terrain, then you’ll just need to make sure that that is the object that you are raycasting at.

[@pshermanart]

This is amazing. So much to absorb. My main interest is seamless offsets. How can I make it look like it's not moving from one direction to the other - have the texture move on the Z axis? I tried changing the initial axis to Z, and shuffling the sine/cos, but didn't get good results.

[@Erindale]

A bit of a weird solution but if you plug your multiply (scene time, divide, multiply) into the Z instead of the X channel and then just before you combine your xyz vector before the noises, you add the previously unused Z channel to the Z channel we generate. So where you have that Sine coming from Y, add the Z to that before it goes into the CombineXYZ before the noise textures

[@pshermanart]

@@Erindale I think this is what you're saying. kzbin.info/www/bejne/p6fGoHimp7GDpa8 Unfortunately, the way I have this set up, doesn't loop. I would be happy to join your Patreon to get some help with this.

[@Rocklaz]

[@John0Phillips]

Would there be a good way to add random instances that track with the terrain? I have been try to add some trees. Instances on the object surface of course just move up and down. I tried instancing based on noise with the same vector as the terrain and it tracks properly but adds only dense clumps of trees.

[@DoctorRobotronic]

Have you found a solution for this? I'm working on the same problem and the best I've managed is getting the trees to move along one axis but they don't follow the height of the terrain and I don't generate new ones as the scene plays out. If you ever figure this out I'd love to hear about it.

[@John0Phillips]

@@DoctorRobotronic I haven't made much progress yet. I'll check back in if I figure it out.

[@DoctorRobotronic]

@@John0Phillips I got as far as getting the trees to follow the speed of the land mass and not move up and down, but they aren't placed vertically correctly and it doesn't seem to be able to be solved by using a math node to just change the height by a flat amount. What I did was I distributed the trees on the original cube, not the displaced one, and then I made a node group from the displacement and replaced the scene time with just a value of 1 representing where the trees are at frame 1. This is the best results I've gotten so far but I'm nearing the point of giving up and just moving on to a new project as I'm not sure it'll be worth the effort, since I won't be able to make the trees loop anyway.

[@Erindale]

Not sure if this works but maybe try mixing in some of MaxEdge's leaf spline tutorial

[@aaronvdw]

I've got this working. What I did was distribute points on the top of the terrain cube. I got those tracking along the x coordinate by taking the x value from the Combine XYZ node used early on in Erin's tree (before he manipulates it with the sin/cos). To get them to sit on the terrain as it moves, I used another Raycast node acting on each of those points. Using the points as the source position for the Raycast, you can then get the hit position that the points are supposed to 'snap' to. Provide that position to another Set Position node for your points. There may be a more elegant way, but this works pretty well for me. OH. One last important bit. You need _another_ set position on those points to reset their x position when they arrive at the edge of the terrain (otherwise they'll just keep going away from the scene). For that I used a Compare node. If less than -0.5, reset it to 0.5 so it can begin its journey again. When I'm done I'll drop a screenshot of the node tree somwhere.

[@post-monk671]

How can I color the surface to whatever I want? can I add my own image/or color ramp to the surface color? It won't seem o register each time I try and connect something

[@Erindale]

Make sure you've assigned the material in geometry nodes. Your own images should work fine although you won't have any UV maps so you'll have to set it to box mapping and maybe use the Position socket of the Geometry input node in shaders. Beyond that, hard to say without seeing your nodes. Maybe ask with a screenshot on my discord server!

[@Erindale]

Nothing actually moves sideways in the scene so you would need to come up with a way to do that without it looking obviously different. You could try creating a patch of points on a grid that is as long as one noise wavelength. Then array a few of those so you have enough for the cycle to repeat as you translate it past the ground. You can then raycast it down so the points land on the mesh and delete any that miss.

[@bzikarius]

hmm… I can`t understand why do you use raycast at 1st stage, if you already have height of displacement and even you can average it (with Attribute statistics) Also why do you use another raycast for steering, if you can get averaged normals?

[@Erindale]

Finding the average displacement wouldn't tell me which direction or how far to move and just using the normal direction doesn't always steer you away from obstacles depending on the ground. Give it a go though! Testing is the best way to understand what you can do with the nodes

Anyone know why in the 'set up displacement section' putting a subtract changes the midlevel and the multiply becomes the strength I don't understand why?

Best way to understand it is just to draw it out on paper. Subtract moves the graph down which moves where the y=0 line is. That 0 position is the mid-level so you're defining where it sits. Multiply is strength because you're literally multiplying the values bigger or smaller. Multiplication always scales away from 0, hense doing mid-level first
