I am attempting to create an extended material which will allow me to change the height of vertices in a plane. That part works, but thee is an unexpected side effect. It appears that the object center is somehow displaced. Here is a pen which illustrates this problem. On the bottom are 4 adjacen…

One last question that was difficult to spot and did not appear until I started moving the planes. It turns out that, even though the planes are moving, the waves are not moving along with them. I think it has to do with the use of modelMatrix, which appears as part of the computation of normals: …

I’m still curious, why do you want to move those planes at all, when you can simply simulate movement, moving just waves of ocean, using a single plane for that? As a ref to what I mean: Endless way II (single plane) Or don’t move the plane at all.

Here is a first effort to create random ocean waves using the sum of several sine waves plus a main Gerstner wave. This includes variations in color plus random whitecaps. I have resized this to my standard small grid size of 1/2 mile. The primary waves are about 4 meters tall (12 feet) and - bas…

I like the demo. It helps that you are at ground level where your maximum visibility flat plane visibility is around 1 mile or so. You can test this by creating an object 6 feet tall and testing to find the distance where the top of the object merges into the ground. The curvature of the earth wo…

One last post on this topic. I have been trying to create random waves by piling on waves from different directions and have had some success. However, the main problem is that all these changes are “smoothed out” and you don’t see a random texture. Instead you get more of a cartoon effect. I ha…

Cool, I made something quite similar. Fly Earth (sbcode.net) [image]

Great minds must think alike! Just today, I started experimenting with MeshToonMaterial and I think it may actually help solve some of the problems I have been wrestling with. To compare: Here is the original diorama . Here is the revised diorama using MeshToonMaterial. (The characters on the sh…

That is amazing. I was not aware that you had already worked on something I was going to work on in the future - i.e. applying what I have learned about displacement of oceans to the displacement of land. In the grid system I was using, the basic unit is 1/2 mile square. As it turns out, by divid…

The boat looks good. I researched but failed to find a workable solution to have flapping sails that could be extended to produced realistic lift, and drag. Also, I’m not sure if using WebGLRenderTarget is the best solution for this. I was just experimenting. It does however mean I don’t need to h…

Your discussion with @seanwasere on Animated Ocean Waves, inspired me to make this small sketch about flight over waves https://codepen.io/prisoner849/full/PoaZjWJ
