OpenGL Procedural terrain - big map test

trying to improve rendering of bigger terrains inside the Antares OpenGL Engine.
at 1:30 you can see tessellation shaders in action.

map size is 1,2 km x 1,2 km
heightmap size is 2048 x 2048

Textures from: FreePBR.com

List of features currently implemented into the Antares Engine:
. PBR materials
. HDR
. tone mapping
. normal mapping
. parallax occlusion mapping (with self shadowing)
. shadow mapping
. omnidirectional shadow maps
. advanced bloom
. parallax corrected cubemap reflections
. planar reflections
. mesh skinning
. procedural terrain generation
. hydraulic erosion
. procedural planets generation
. instancing
. billboarding
. basic inverse kinematics
. basic water rendering
. camera path interpolation

This inspired me a lot today, I got out of bed went for a walk then came back and fixed my texturing issues on my terrain

Very much looks like an early version of a Skyrim-type game. If your progress keeps up, I think you’ll have something special!

Good work, always enjoy watching your videos.

Looking pretty! :) Good inspiration to pick up my rendering project again.

Nice work, keep this up. I wanna do the same thing and never find the time ! Progress this my friend.

I didn't know OpenGL was capable of that

[AlbertRyanstein]

Very impressed. Not sure if it discouraged me or encourages me. Currently applied some textures the first time last night but since the Y values was 90 it stretched. Should I just get rid of 90 degree terrain for now. I'm using fractal and then fir.

Great Work!! Can you add the foliage from your previous videos, or will it make the game too slow? Also, please make tutorials. You bought the microphone, don't leave it unused.

why opengl when it is deprecated all over the place
