示例1: InverseLookAtMatrix
void Camera::InverseLookAtMatrix( void )
{
Vector rotVec = at-eye;
rotVec = ( ball ? ball->ApplyTrackballMatrix( rotVec ) : rotVec );
Point finalPos = ( eyeMove ? eyeMove->ApplyCurrentFrameMovementMatrix( at-rotVec ) : at-rotVec );
Matrix4x4 m = Matrix4x4::LookAt( finalPos, at, up ).Invert();
glMultMatrixf( m.GetDataPtr() );
}示例2: LightLookAtInverseMatrix
// This multiplies onto the current matrix stack an inverse look-at matrix
// (equivalent to Invert( gluLookAt() ) -- if such an operation were possible)
void Scene::LightLookAtInverseMatrix( int i )
{
Point lightPos( light[i]->GetCurrentPos() );
Vector view = camera->GetAt()-lightPos;
view.Normalize();
Vector perp = abs( view.Dot( Vector::YAxis() ) ) < 0.95 ? view.Cross( Vector::YAxis() ) : view.Cross( Vector::XAxis() );
perp.Normalize();
Vector up = perp.Cross( view );
Matrix4x4 mat = Matrix4x4::LookAt( lightPos, camera->GetAt(), up ).Invert();
glMultMatrixf( mat.GetDataPtr() );
