GL_EYE_LINEAR

テクスチャー座標自動生成には２つのオプションがあります。GL_EYE_LINEARをセットすると、テクスチャーの位置がカメラに固定されます。図形が動くと模様が変わります。例えば、スライド上映中にスクリーンの前を横切った人のようなものです。あるいは、通り過ぎる鏡面仕上げの車に映るあなたの姿のようなものです。ただあまり大きなテクスチャーは大きな負荷になるそうですので、用途は限られそうです。
glTexGeni(GL_S, GL_TEXTURE_GEN_MODE, GL_EYE_LINEAR)
glTexGeni(GL_T, GL_TEXTURE_GEN_MODE, GL_EYE_LINEAR)

一方、GL_OBJECT_LINEARを指定すると、図形と一緒に模様が動きます。テクスチャー柄の洋服を着た人が動き回るようなものです。これは普通にテクスチャですね。
glTexGeni(GL_S, GL_TEXTURE_GEN_MODE, GL_OBJECT_LINEAR)
glTexGeni(GL_T, GL_TEXTURE_GEN_MODE, GL_OBJECT_LINEAR)

Automatic texture coordinate generation has two options. GL_EYE_LINEAR fixes relative position of texture and camera. This is something like you walk across a projection screen during slide show.
glTexGeni(GL_S, GL_TEXTURE_GEN_MODE, GL_EYE_LINEAR)
glTexGeni(GL_T, GL_TEXTURE_GEN_MODE, GL_EYE_LINEAR)

GL_OBJECT_LINEAR fixed texture potition to the object. When object moves, texture moves as a skin of the object.
glTexGeni(GL_S, GL_TEXTURE_GEN_MODE, GL_OBJECT_LINEAR)
glTexGeni(GL_T, GL_TEXTURE_GEN_MODE, GL_OBJECT_LINEAR)
