This chapter describes coordinates, ratio, ratio-formula, area of a triangle, and locus. If P is a point in the plane of the axes and PL and PM perpendicular to the x -axis and y -axis respectively, then the distances MP and LP are called the coordinates of the point P in regard ...

If the value is negative, then that point is located in empty space (such as air or water). The boundary between positive and negative values—where the density value is zero—is the surface of the terrain. It is along this surface that we wish to construct a polygonal mesh. We use th...
Both orthographic and perspective transforms can be constructed with 4 × 4 matrices (Chapter 4), and after either transform, the models are said to be in clip coordinates. These are in fact homogeneous coordinates, discussed in Chapter 4, and so this occurs before division by w. The GPU’s...
With less chip area dedicated to cache memory and control logic, latency for each shader core is generally considerably higher than what a CPU processor encounters [462]. 举个例子:一个面片被光栅化之后,产生了两千个被片元覆盖的,需要处理的像素;因此一个像素着色器需要调用两千次。想象一下,如果...
Remember their initial values are retrieved from the constant area. Exact initialization processing is development tool specific. main Function When the development tool initialization is complete, control transfers to the user-supplied main function. At this point, the application controls what happens ...

More droughts will occur, the drought-prone area will continue to expand, and droughts will grow more intense. Except for the increased rainfall in the western part of the northwest, the northern and southern part of the northeast could become permanently dry.18 Meanwhile, floods, heavy rainfall...
The area displayed on the map is itsregion, an MKCoordinateRegion. This is a struct comprising a location (a CLLocationCoordinate2D), describing the latitude and longitude of the point at the center of the region (the map’scenterCoordinate), along with a span (an MKCoordinateSpan), descri...
The alert indicates the existence of an area where clients are continually experiencing poor signal coverage, without having a viable access point to which to roam. The controller discriminates between coverage holes that can and cannot be corrected. For coverage holes that can be corrected, ...
