Here is simple software renderer. It means, that it doesn't use OpenGL or DirectX to perform rendering. All that it use is WinAPI functions to put image block on a screen.
Why software rendering?
Just educatonal and kind of research goals.
Now it supports:
- Loading some graphics files with mesh data(.obj). Also it can load bmp files via CImg library.
- Lighting (ambient, directional and point).
- Constant, wireframe, flat and gouraud shading.
- Simple material support.
- Z buffer.
- Bilinear filtering for texture mapping.
- Mathematical operations with scene nodes like scaling, translating and rotation.
- Perspective correct texture mapping.
- Customizable camera.
- Configuration files (you can tune lights (intensity, position, etc) or add objects, that will appear in a scene). Also you can setup position of objects through the scene config file.
Check out this to get compiled example. Use wasd to perform camera movement, mouse + left mouse button - cam control.
This renderer supports only Windows. In order to compile it you should use Visual Studio 2012 (the project uses C++11).
The main directory is organized as follows:
- client/ - project for library testing.
- renderer/ - main part: renderer code, that compiles into static library.
- resources/ - some mesh data and renderer config files (with .json extention).
- www/ - images for future wiki.
- README.md - this file.
- df3d.sln - MSVS2012 solution file.
Is here. There you can see some screenshots.
