I use algorithm, which is explained in
Practical and Robust Shadow Volumes (.pdf) (2153 KB).

Program request hardware accelerated 8 bits stencil buffer.

source code and program – 25kB

Request:
GL_ARB_multitexture, GL_ARB_texture_env_combine a GL_ATI_envmap_bumpmap.

source code and executable – 320kB without jpeglibm.lib

Dot Product 3 Bump Mapping is per-pixel lighitng. Use dot product per-pixel. Standard lighting in OpenGL is computed per-vertex. I use equation:

color = ambient + (N.L)xDifuzeColor + (N.H)^SpecExp x SpecularColor
N is normal vector, this is texture map, created from bump map with Sobel-Prewitt filter.
L is light vector. L = light_pos – vertex_pos
H = HalfVector = normalize[ ( eye_pos-vertex_pos ) + ( light_pos-vertex_pos) ]

Request: GL_ARB_multitexture, GL_ARB_texture_env_combine, GL_ARB_texture_env_dot3.

source code and executable – 430kB without jpeglibm.lib

Request: GL_ARB_texture_cube_map

source code for library jpeglibm.lib – 207kB
source code and executable – 530kB

Terrain is important part of more type games.
I use octree and volumetric fog.

I use detection collision from www.gametutorials.com, there is this field good explained.

Texture projected on objects is interesting effect. This makes it possible do interesting lighting of scene, example uses light through stained glass.

Sphere mapping is technique of environment mapping. This uses a sphere map. A sphere map is a single texture of a perfectly reflecting sphere in the environment where the viewer is infinitely far from the sphere.

Unlike cine-camera where fast moving objest are blurred, each image rendered in OpenGL is sharp. This causes discontinuous motion also above FPS.
