How does transvoxel algorithm work and how can I implement It?
The transvoxel paper is a fairly in-depth work, discussing a variety of topics on how to create an entire voxel terrain system, including an overview of marching cubes, how to fix the ambiguity ...

How does transvoxel algorithm work and how can I implement It?
The first thing I didn't understood was if transvoxel is a modified
marching cubes or a second layer that modifies the work of the marching
cubes.
My reading of the paper is that Transvoxel's ...

How to make texture look sharper and more detailed, when you look closer?
This is usually solved using detail maps. (See e.g. Unity's documentation about the technique here)
For this you make a tiling texture with fine-scale detail, either as an albedo (surface colour) or ...

Octree Terrain Destruction and LODs
The primary goal of LOD is to reduce the cost of drawing by not drawing unnecessarily fine detail. It is not usually about discarding information from RAM. In fact, in a conventional polygonal-model ...

How can I blend grass LOD's smoothly in unity, similar to the method in BOTW?
One often-overlooked visual aspect of stuff like grass or hair (ie. tufts of stuff sprouting out of a surface) is how the normals affect lighting. Specifically, because the default normals stick ...

Level of detail for the map of stars
One obvious error in your current implementation is that you should combine nodes based on their total area, and not total radius. Otherwise you're overstating the visual effect by a squared factor - ...

How can I efficiently render a large, zoomable world map?
The search term you are looking for is "Level of Detail" or "LOD". It basically means that you adjust the level of detail of the map depending on the zoom factor.
You can have a really high level of ...

Zooming in on procedural generated 2D terrain? (LOD)
Lets define your noise function for terrain generation as f(x,y).
f(x / 2, y) will set the zoom on the X axis to 200%

When should I make different LODs?
Different LOD levels are only useful for your game when two conditions are true:
You show the objects from many different distances, so the different LOD levels will actually be used in practice.
You ...

Using octrees as LOD system
As Kromster alludes, this apparent problem occurs because of the small scale of your example. Usually when we reach for sparse octrees, we have more than two levels of subdivision.
Here's your same 2D ...

HLSL mipmapping not working
You don't.
Unfortunately some online resources don't make this explicit, but the code you've given is actually not HLSL; instead it's part of the old (and deprecated) effects framework. What ...

Performance problem with chunked LOD
A few things you can try...
Share your vertices
You mention you have 16x16 grids of 1024 vertices. But 16x16 is only 256 cells. So it sounds like you're rendering 4 separate vertices for each square ...

Imposters in Unity - How to set which color is used as 'transparent' in the RenderTexture?
So the solution turned out to be quite simple. After doing all the steps I mentioned in the question, you will need to make sure the camera that you use to generate the RenderTexture has it's Clear ...

Creating a Full Stadium of People, Ready as a Game Asset (ie. not too CPU intensive)

Which Terrain LOD algorithm should I use for super large terrain?
Forget about ROAM. That's the pre-3DFX era of SW rasterizers. I mean, if you're bored, it's a fun exercise, but it's useless in today's era of thousands of shaders units...

No, there is nothing that can be done at that point.
