New Renderer (OpenGL 3.3)

I am not sure I understand the question. In the pictures there is no normal mapping yet. Just standard normals, which are 32bit per dimension. I was surprised how good it looked without it (hence the pictures). Guess it is the lighting model I choose, which is not Phong (obviously). I experimented a lot with such models some time ago.

And yes, of course it works with OpenGL (wine runs it too, like many other games), the problem is getting there. For which you have to know your stuff, even looked at the wine sources for some things so that I don’t reinvent the wheel.

I found some papers and implemented some of their solutions. Basically it is a mixture of different models. There even is a color shift of the reflection depending on the viewing angle. If you read up on it you can quite easily mix the equations and build one to your liking. There are also papers which compare different lighting models. And as always I am not quite satisfied with the results yet

There also is still a problem with dark spots in combination with compression artifacts and the resulting reflective color. So it is not finished yet. The shader is taken from my own 3d engine.

The next step is getting the name of the texture which is currently active. Lets hope I somehow get it Without it it gets quite hard to do more.

Depends on how good your math understanding is. It’s nothing too complicated, although you should be able to read/understand the formulas and convert them to shader code.

P.S.: I got the texture names now, so that is out of the way.

Some corrections + normal- and parallaxmapping. Still WIP.

What do you guys think? This site could still use better image handling (so right click on the image and select “view image” or smth like that)

Yeah, the base textures are not easy to work with, also the heightmaps are not ideal. I don’t have the time for proper textures

Also the material settings matter a lot and maybe I will change the lighting model again. Here is an example how easily 2 values change the look:

I think it looks better than before, though.

Plastic I can do

Note: Plastic doesn’t have a reflectance with the own material color. It’s usual plane white.

The problem mostly is, that gray still results in a white reflectance color. Maybe that is an issue of the lighting model. An issue I will have to look at later.

Hehe, that is a decision of the texture artist, not mine. I just choose vanilla textures as an example, because everybody knows them.

P.S.: It is not an engine, just a wrapper from d3d8 to OpenGL plus some changes. I plan to release it for everyone as soon as I think it is polished enough (which will take some time, since as always I have other projects in parallel + university stuff).

P.P.S.: I am not finished implementing rendering techniques. Parallax mapping etc was just the start
