hi there,
after a year of abstinence i went back to an old project of me.
The reason why is stopped developing stands in the title.
But now iam interessted about whats going on.
Description of the project:
I have a little bit more complex Godot project to test different things. One bigger part of that is a terrain generator (i call it “Surfafe”, it sounds like “surface” spoken from a german when eating a hot potato 
:D).
You can find this part of my project here (100% gdscript):
https://gitlab.com/heroldini/surfafe
(Its a node, but im not sure if its cleanly standalone )
This is roughly how it works:
-
I split the world in “sections”. one section per default is 16x16x16 blocks tall.
Each block is defined by its corners and is generated with marching cubes tables. -
A simpel noise generator generates data for a procedural landscape (very basic)
-
Up to now it generates a predefined number of sections, when the game starts. No generation while playing atm.
-
It has a LOD-system included (disabled per default) which generates each section for lower resolution (but there are still missing the transitions)
The Problem:
Generation works well for me. But when you generate a bigger terrain you get a very low frame rate. But i do not really understand why.
For example i added a 3D-model with about 250,000 vertices made with blender. It runs very smoothly. I can add 10 of them with no problem.
But when i generate a terrain with my generator it has very low performance when it has about 300,000 vertices and i look in its direction.
If i look in another direction (empty space) the fps raise to normal.
Tested in Godot 3.1.1 (then) and now in 3.2.3
Hardware: amd ryzen 7; geforce 1080
I would be happy if someone could explain to me what I am doing wrong
thx
