복사꽃 무더기로 피더이다

멀고 먼 인생길, 어찌 평탄한 길만 있겠습니까. 때로는 오르막, 또 때로는 내리막. 더러는 주막집 문전걸식에 더러는 잔칫집 진수성찬. 눈보라 몰아치는 엄동설한 지겹도록 길더니, 걷다 보니 어느새 화창한 봄. 걸음마다 복사꽃도 무더기로 피더이다.


아...멋지다.

Galactic coordinate system

Galactic coordinate system

멋지다.

The galactic coordinate system (GCS) is a celestial coordinate system which is centered on the Sun and is aligned with the apparent center of the Milky Way galaxy. The "equator" is aligned to the galactic plane. Similar to geographic coordinates, positions in the galactic coordinate system have latitudes and longitudes. The northern galactic pole is located in the constellation of Coma Berenices while the southern pole lies in Sculptor.

Manipulatory and ambulatory space

Lederman, Klatzkey, Collins, Wardell (1987)  made a distinction between manipulatory and ambulatory space, the former within reach of the hands and the latter requiring exploration by movements of the body.

Perspective correct barycentric coordinate

Perspective effect가 있으면, projected space에서 barycentric 계산 틀려짐.
아래는 nvidia 어디에선가 가져온 자료.

그냥 Object space에서 해결.

시간나면 다른 방법으로도 풀어봐야겠다.

cursor위치에서 vertex normal을 이용하여 normal vector interpolation을 하기 위함

Perspective-correct barycentric coordinate for picking:


     float b0 = _area[0];
     float b1 = _area[1];
     float b2 = _area[2];

     float w0 = p_rot_face[0].z;
     float w1 = p_rot_face[1].z;
     float w2 = p_rot_face[2].z;

     w_= b0/w0 + b1/w1 + b2/w2;

     w_ = 1.0/w_;

     _area[0] = _area[0] / w0 * w_;
     _area[1] = _area[1] / w1 * w_;
     _area[2] = _area[2] / w2 * w_;
