摘要： 设总体\(X\thicksim N(\mu,\sigma^2)\)，\(\sigma^2\)为已知，\(\mu\)为未知的，设\(X_{1},X_{2}...X_{n}\)为总体\(X\)的样本，则求\(\mu\)的置信区间。 知道\(\overline{X}是无偏估计\)，且有 \[\frac{X 阅读全文

摘要： 随机试验: 可以在相同条件下重复进行 多种可能 在实验前不确定是那种结果 样本空间: 随机现象的一切可能基本结果组成的集合称为样本空间 样本点: 样本空间中的一个元素 样本空间中的元素可以是数也可以不是数. 样本空间至少有两个样本点，含两个样本点的样本空间是最简单的样本空间. 从样本空间含有样本点的 阅读全文

摘要： Rendering Equation Hemispherical Formulation Let us assume that \(L_{e}(x \rightarrow \theta)\) represents theradiance emitted by the surface at x and 阅读全文

摘要： Brief History Models of Light The models of light used in simulations try to capture the different behaviors of light that arise from its dual nature: 阅读全文

摘要： OVERVIEW OF THE ENGINE The physics engine we have built has four distinct parts: The force generators (and torque generators) examine the current stat 阅读全文

摘要： Vector Quantization Quantization(量化) Definition: a process of representing a large–possibly infinite – set of values with a much smaller set. Widely U 阅读全文

摘要： We I have a set of contact data from the collision detector, and have the rigid-body equations of motion, including torques and forces. We are now rea 阅读全文

摘要： Many collision detection systems perform this check for each pair and return a single point of maximum interpenetration if the objects are in contact. 阅读全文

摘要： COLLISION DETECTION PIPELINE Collision detection can be a very time-consuming process. Fortunately there is plenty of room for improvement. The two ke 阅读全文

摘要： our physics engine is now capable of simulating full rigid bodies in full 3D.The spring forces and other force generators will work with this approach 阅读全文
