terrain | Create a 3d terrain with WebGL | Game Engine library

One way to determine what section of your terrain should be culled is to use a quadtree (for a heightmap) or an octree (for a voxel map). Basically, you divide your terrain into little chunks that then get divided further accordingly. You can then test if these chunks are in your viewing frustum and cull them if necessary. This technique was already discussed in great detail:

• Efficient (and well explained) implementation of a Quadtree for 2D collision detection
• https://www.rastertek.com/tertut05.html

I saw some websites saying to use GL_DYNAMIC_DRAW instead of GL_STATIC_DRAW, but I did not understand it.

These are usage hints to OpenGL on how the data will be accessed so the implementation has the ability to apply certain optimizations on how to store/use it.

usage is a hint to the GL implementation as to how a buffer object's data store will be accessed. This enables the GL implementation to make more intelligent decisions that may significantly impact buffer object performance. (https://www.khronos.org/registry/OpenGL-Refpages/gl4/html/glBufferData.xhtml)

Please note that these are only indications, no restrictions:

It does not, however, constrain the actual usage of the data store.

Because you will likely update your VBO's and IBO's constantly (see culling) and only want to draw them GL_DYNAMIC_DRAW would be a good choice:

The data store contents will be modified repeatedly (because of culling) and used many times. The data store contents are modified by the application and used as the source for GL drawing and image specification commands.

as I have googled that it can affect the performance of the game

Well, it will cost some performance to cull your terrain but in the end, it will likely gain performance because many vertices (triangles) can be discarded. This performance gain may grow with larger terrains.

Just add reversescale=True as below:

LibGDX is not and game engine so don't expect any "generateTerrain()" method. You need to implement it yourself.

Here you can find general information about how to use libGDX for 3D.

And here you can find actual code that creates a height map.

I have tried something like this

I solved it after finding a reference to THREE.UVMapping in the docs. When sending the geometry to the GPU, textures coordinates need to be a biyection from the vertices coordinates. To achieve this, I defined the following three attributes in my blocks:

That's not going to work, because you don't know what layers to assign to that tree relative to your person sprite. Specifically, if the person is south of the tree, you want it to draw on top of the tree, while when it's north of the tree, you want it to be under the tree.

You will instead have to sort your sprites so that they're draw from the bottom of the screen up.

Figured it out. For those wondering the ordering is -x to +x and z+ to z- . So a for loop such as the following will get you the right ordering. width and height here are in terms of the number of tiles/height values per row/column

The problem is with this line:

cordinates="[" + df["LAT"].astype(str) + "," + df["LON"].astype(str) +"]"

You are generating a string literal and passing that in.

Try replacing that line with:

cordinates = [(lat, lon) for lat, lon in zip(df["LAT"],df["LON"])]

This will generate a list of (lat, lon) tuples, which should work. I also don't think you need to cast them to str

You can add a req check in observe -
