Hello everyone, I present my implementation of a terrain for the Playcanvas.
Great! Any plans for texturing?
Yes, I’m already developing it.
Looking great so far 
Upgrade: Add support texture painter, support 8 channels. Save to special file format or png.
Upgrade:
Example: terrain 16x16km.
WebGL2
WebGPU (use baseVertex)
Terrain: 1x1km width scale 8 = 8x8km.
@Wagner - feel free to create a PR for the baseVertex on WebGPU.
The video shows a map with the original size of gta 5.
Improved algorithm and optimized memory usage for webgl. Map size 16x16 uses 34 MB for indexes and 269 MB for vertices.
So is this a plane with a bunch of premade subdivisions or is it a regular plane that is subdividing itself on the fly as needed?
Also were you planning on making this code publicly available or sharing it in any way?
The algorithm is based on geomipmapping.
I have been doing research for a long time which algorithm is better to use quadtree, voxel, geomipmapping.
Optimizing the structure to use video memory, etc.
Some approaches cannot be used due to limitations of WebGL2 or WebGPU.
Might i ask what specs are required to run something like this?
For browser development I use MSI GE 60 laptop,
You should clearly understand that this type of landscape is suitable exclusively for games with a huge open world, like DayZ, WarZ. Because if you use less landscape, it will be cheaper to use a baked model.
Example: Terrain Generation from Heightmap | PlayCanvas Developer Site
Is the subdividing based on rounding various values or just by location? What I mean is a scenario where point 1 has a height of 0, point 1.25 has a height of 5, point 1.5 has a height of 30, point 1.75 has a height of 5, and point 2 has a height of 0. Would the height of 30 be used in some calculation or just overwritten with a flat plane from 1 to 2?
The division occurs at the level of x, z coordinates.
Height is of secondary importance.
Read more about geomip mapping / quadtree.
So if there was a really tall spike in between two coordinates it would just get ignored.
Sorry if my questions are annoying, this is just quite new to me. Would it be possible to have overhangs?
Are you talking about the accuracy of the height map? The whole map is made up of LODs, so when you are in a LOD square, you don’t lose any height.
No, overhangs and caves are not supported with this method.
Is there any system like this that would allow for overhangs?
