2.6.2 Eliminating Normal Maps It should be possible to directly compute normals in the pixel shader by accessing four filtered samples of the elevation map. At present, vertex texture lookups require that the elevation maps be stored in 32-bit floating-point images, which do not s...
Because characters in the distance take up fewer pixels on the screen, there is no need for them to be as highly tessellated as characters closer to the camera. In addition, distant characters do not need to sample from the normal map, or calculate complex lighting. Thus we implement an ...
We've already had a deeper look into most of what happens in this piece of code: how the iface<Mather, Adder> interface gets created, how it's laid out in the final exectutable, and how it ends up being loaded by the runtime. There's only one thing left for us to look at, ...
For example, the following command instructs the link-editor to create a dynamic executable that is named a.out using only the input file test.o.$ ld test.o Typically, a dynamic executable requires specialized startup code and exit processing code. This code can be language or operating ...
Example 2–1 Looking Up a Connection Factory // Create the environment for constructing the initial JNDI // naming context. Hashtable env = new Hashtable(); // Store the environment attributes that tell JNDI which initial context // factory to use and where to find the provider.// ...
Done? OK, now add up all the time you have spent doing battle with idiotic internal threats. Enough said?When I consider the things that really pose a threat to an enterprise's users' or owners' interests, I usually end up with a roadmap that looks something like this:Fault tolerance ...
If a bit is set in the bitmap, it signals that the corresponding character must be escaped before it is transmitted across the link. To tell your peer that it doesn't have to escape all control characters, but only a few of them, you can specify an async map to pppd using the ...
When you AND this with status, only the FlagBits::Ready bit in status will be set to 0; all other bits in status will be left at their original setting.Note that the op= operators are not defined for enum values so you cannot write:...
but with Windows supporting fast user switching this is no longer a driving factor. When multiple profiles are set up, Outlook is typically configured to prompt at boot to allow the user to select which profile Outlook should load. Currently most users have only one single profile and add all...
but if you choose to use a different flavor of spool directories, for example, Taylor UUCP, you might have to write your own. If you don't care about the number of spool files (because you're the only person using your computer and you don't write articles by the megabyte), you may...
