Gdevice - procedural content oriented 3D engine for low-end machines

Gdevice is a 3D graphics engine oriented to procedural content and optimized for low-end machines or embedded systems with OpenGL 1.2.1.

This video shows a few places you can find into the generated world. I wanted to save this video because here the engine is still using a plain OpenGL 1.2.1 fixed function configuration and this will be a comparison term for future improvements (GLSL, GPGPU capabilities..) which will require a refactoring of many parts.

The demonstration also shows gdevice's main features:

1. procedural terrain generation at runtine (while the observer moves).

2. Terrain LOD scheme that enables rendering of huge and dense terrains (here is configured for 16km view distance and 1024 vertices per squared meter).

3. fixed function multitexturing technique.

4. 64KB uncompressed executable with no external dependencies (except for opengl.dll).

Thanks. You know, it's frustrating for me too sometimes. And while you admire my work, I admire the work of others that is way better than mine. However this is an endless source of pleasant learning for me :-)

@gdevice3d Its probably stupid to ask this, but I would love to see how you did this.. a tutorial or something.. I read your blogs.. but it really doesn't explain in detail what all you did here. The LOD is where I am like.. OMG.. hahaha.. pure genius my friend.

@TheEpicureanist I actually use my blog as a notebook to take track of my thoughts about this hobby work. So it is more for myself than for explaining things out or show off or sell. I just sometimes like to come back to old videos to see how the new one compares.

Yes, if you want to render kilometers of view range and yet keep the closest surroundings at a sub-meter detail, then you need to variate the density of points of your mesh (aka level of detail). You need a LOD scheme or whatever :)

I remember it was about 1 million of triangles in that video.

calma, una cosa alla volta.. :)

You sir are my new GOD ! That is brilliant.

Perfect for flight simulators. What is the average polycount drawn each frame?

me too!! :P

Pretty cool, would love to see you further develop this!
