摘要:
object/local/modeling space -----> world space : Modeling Transformation (glTranslate3d,glScale3d,glrotated)world space-----> view/eye/camera space: View Tansformation (gluLookAt)以上两步在OpenGL中通过一步实现,ModelView Transformation,代码是glMatrixMode( GL_MODELVIEW),实现从局部空间(local space)到观察空间(view space)的变换 阅读全文
