Learn how Java next-generation languages reduce boilerplate code and reduce complexity
The limitations faced by the Java programming language at birth are different from those faced by today's developers. Specifically, there are primitive types in the Java language due to the performance and memory limitations of hardware in the middle of the 90 's. Since then, the Java language has evolved, with automatic boxing (Autobox) eliminates a lot of hassle, and the next language (Groovy, Scala, and Cl
stream-out is easier than gs so, and has some pretty useful applications by itself (e.g. caching skinned vertices ).
So here's how it's done in d3d10 and 11: You simply pass vertex shader bytecode (instead of GS bytecode) to creategeometryshaderwithstreamoutput. yes, the docs mention something about "Size of the compiled geometry shader" here-Ignore it. what you get back is a geometry shader object that you can then pass to gssetshader. this is, in effect, a null geometry shader-it doesn't act

Apple officially released the beta OS X 10.8.4 system, but did not elaborate on what updates and new features the new beta system contains.
According to people familiar with the matter, the current OS X 10.8.4 beta version number is 12E27, and the previous OS X 10.8.3 official version just two weeks ago, the version number is 12d78. The beta system is currently open only to Appleseed Test members and is not expected to be formally released to all dev

Pulldown and Pullup Primitives
There are three types of digital circuits: high, low, and higher impedance. Some applications do not want a high-impedance state, which can be stabilized by a pull-up resistor or a pull-down resistor, as shown in th
primitive language. Although, there are many different layers throughout the system, the communication between tiers is very similar. For example, PHY, Mac, and NWK layer both provide data services for their upper level, and the mechanism of requesting data Service is similar: the high level requests the transfer to the subordinate through D-SAP, and the subordinate transmission succeeds and returns the state to the superior. It is precisely this similarity that makes the "service primitive"

Coordinate system and basic elements (1)
Direct3d Basic Elements
Primitives is a basic graphic representation defined in direct3d. It is a set of vertices that constitute a single object. The simplest element is a set of multiple vertices in a three-dimensional coordinate system. It is called a point list ). A polygon is a polygon. A polygon is a closed graph composed of at least three edges. The simplest polygon is a triangle. direct3d uses a triangl
Welcome back! This time, we'll look into what is perhaps the "poster boy" feature introduced with the d3d11/shader 5.x hardware generation: tessellation. this one is interesting both because it's a fun topic, and because it marks the first time in a long while that a significant user-visible component has been added to the graphics pipeline that's not programmable.Unlike geometry shaders, which are conceptually quite easy (it's just a shader that sees whole

access this critical section after one thread has entered will be suspended and continue until the thread entering the critical section leaves. When the critical section is released, other threads can continue to preempt, and in this way achieve the purpose of atomic manipulation of shared resources. The critical section contains two operations primitives: EnterCriticalSection () enters the critical section leavecriticalsection () leaves the critical
to the "Read-Modify-write" operation, atomic operations can also be performed on an atomic basis based on other more flexible mechanisms to create critical zones.
3. Optimization and memory barrier
(1) After the source code is converted to assembly, the Assembly command will be re-ordered. If an error occurs before the commands after the synchronization primitive are scheduled to the synchronization primitive, a barrier is introduced.
