Physically Based Rendering: From Theory to Implementation by Matt Pharr PDF

Книга является отличным справочным пособием для всех кого интересует photorealistic rendering. В книге рассмотрено большое количество новых алгоритмов с реализацией на мета-языке (например дается subsurface scattering). Стоит отметить что Matt Pharr является редактором серии GPU gemstones от NVIDIA!

P. S. Спешу предупредить, что данный файл является рабочим вариантом книги и здесь текст (. .. а рисунки тем паче) представлен в начальном редакционном виде (общее число страниц не совпадает финальным вариантом, ИМХО за счет отсутствия части рисунков и более плотной верстки).

P. P. S. Данный файл был любезно предоставлен мне из торрентовской сети Dimitry N. за что ему огромное спасибо. Ежели кто найдет полную версию книги - сообщите, также ищу полные версии GPU gemstones 1,2.

Fundamental Vector3D operations. double precision as explained in Chapter 5. 1 We use meters for units in Cartesian coordinates and for height in geodetic coordinates, which is common in virtual globes. Let’s turn our attention to ellipsoids, which will allow us to more precisely define geographic coordinates, and ultimately discuss one of the most common operations in virtual globes: conversion between geographic and WGS84 coordinates.

The set of points r units away from c define the sphere’s surface. For convenience, the sphere is commonly centered at the origin, making its implicit equation: x2s + ys2 + zs2 = r2 . 1) is on the sphere’s surface. We use the subscript s to denote that the point is on the surface, as opposed to an arbitrary point (x, y, z), which may or may not be on the surface. In some cases, it is reasonable to model a globe as a sphere, but as we shall see in the next section, an ellipsoid provides more precision and flexibility.

3. Partial Ellipsoid implementation. The WGS84 ellipsoid is widely used; we use it in STK and Insight3D, as do many virtual globes. Even some games use it, such as Microsoft’s Flight Simulator [163]. The most flexible approach for handling globe shapes in code is to use a generic ellipsoid class constructed with user-defined radii. This allows code that supports the WGS84 ellipsoid and also supports other ellipsoids, such as those for the Moon, Mars, etc. 3). 2 Ellipsoid Surface Normals Computing the outward-pointing surface normal for a point on the surface of an ellipsoid has many uses, including shading calculations and precisely defining height in geographic coordinates.
