书籍介绍
这不是一本可以从头读到尾的图形学教材，而是一把专门对付几何计算的钥匙。读者反复提到：RTR（实时渲染）啃完后才发现，真正支撑画面的核心公式其实是一堆数学推导，于是回过头来借这本书补几何的窟窿。全书以

精彩摘录
- "subtractive cancellation"
- "M = cos θI + (1 − cos θ )w ˆ ⊗ w ˆ + sin θW"
- "Definition and Properties"
- "Since this is just a function, we know that the minimum occurs exactly when the partial derivatives of D2 with respect to b and m, respectively, are zero."
- "“out of the page""
- "Thus, if Q is not at the origin, then we must translate by the difference between Q and its rotated counterpart."
- "The bottom row is computed as usual by factoring out the above and the point P from Equation 4.34:"
- "T (u)"
