Landscape v8

[pf shadoko]

Hi coders,

the v8 of my "Landscape" demo
many improvements in this version !

I want to provide a lib (c backend) with a doc to use it in your games
if someone can help me, I don't know anything in this field

(to download copy the link in a new tab (I think it's related to the fact that it's not https))

Sorry just for Windows64 for now

PS : some shaders may be messed up, if you see some weird stuff, tell me about it

Just crazy

Whah, really impressive, thanks pf shadoko !
Really smooth in 1920x1080.
Tried all five terrains, no problems with a "small" 4 cores / 4 threads Celeron N5105@2Ghz with integrated Intel UHD Graphics.
Very nice grass texture.

Very nice! Smoother and with more detail than some commercial games I've seen.

I always admire your work.

gorgeous!

I really love your demos...
But, is there a chance to change the LOD? sometimes the background and farther aways things looking terrible.

@Cyllceaux
can you clarify things
if it seems to be a display bug can you post a screenshot

[Cyllceaux]

I tried. But it is always a black picture
But I mean, the LOD "jumps" hardly. In the wireframe-view there are mountains and trees shows from a single triangle to a complex object. I count 5 "jumps".

[pf shadoko]

ah yes, impossible to make a screenshot (due to the screen mode)
yes, the changes of lod are a bit brutal, especially visible with the cliffs

in v9, it's better, the terrain mesh is finer (25cm instead of 1m in v8)

[idle]

looks really good. I'm guessing its using a quad tree to page in the LOD can you make a wider field of view not the actual view or increase the depth, which is perhaps what you've done going to 0.25m vs 1m that might rid of the abrupt LOD transitions. It's only seems to do it when you turn around or views obscured by cliff.
I like the details of the plants and water looks great.

@idle:
no, in v9, i just divided by 2 the width of the terrain grid (for all lods), and add a close lod, it decreases clearly the transition between lods. it doesn't require a lot of resource more.

I tested it on a machine more powerful than mine (amd ryzen 7) and the performance was very bad (about 10 fps)
if someone had this problem, thank you to report it to me, I will do some test code to find the origin of the problem

[jacdelad]

I just tried it and it's amazing (also the size!). Worsk great in 4K on my Ryzen 5800X with a 12 years old midrange graphics card.

So...how can we exploit you and make use of it?
