From: http://blog.csdn.net/liu_lin_xm/article/details/4850630 Excerpt from "GPU programming and Cg language primer 1rd edition" Algorithm flow Figure 47 shows the implementation process of Volume Rendering using the ray projection algorithm. First, we need to render the forward and backward surface depth graphs. This is to calculate the maximum distance of Ray traversing and serves as the basis for loop sampling control; then, the vertex position

After using @ interface to declare a class, you can use @ implementation to implement the class. The syntax for class implementation is as follows: @ Implementation class name method implementationCode; @ End; Instance: @ Implementation person-(nsstring *) name {return name;}-(INT) Age {return age;}-(void) s

The so-called RPC is a remote method call, or simply by mq,tcp,http or the network protocol you write to transmit what I want to call the other side of the interface, the other side processing and then return the results to me. That's a simple process.At runtime, a client-to-server RPC call, with an internal operation of roughly 10 steps, is as follows:1 . Calling client handle; executing transfer parameters2. call the Local system kernel to send network messages3. Message delivery to remote hos

Search nearby PHP implementation code and search php implementation code The examples in this article share with you the specific code for implementing PHP search nearby for your reference. The specific content is as follows: Implementation ideas: First, we should think like this: since we know the longitude and latitude of the user's current location and the ran

Recursive Implementation of itoa functions (implementation of second-level pointers) and recursive pointer of itoa FunctionsProblem proposal In C Programming Language, two functions are reserved for recursion. the itoa function is used to convert an integer into a string. There are already versions implemented using loops in the book, but the reverse result is obtained directly. You need to call the reverse

C # For interface implementation, display implementation interface, and inheritance, First, list the code I wrote: Interfaces, abstract classes, and implementation classes 　　public interface IA { void H(); } public interface IB { void H(); } public abstract class D { public abstract void H(); } public class C : D,IA

I will share my examples and ideas with you to learn together. The specific implementation result 1 of the timeline is as follows: Figure 1 Step 1: When we see this graph, the first response we think of is to us

Let's talk about the 2D implementation of the water surface effect (1) and the 2d implementation of the water surface. 0. Introduction I have always wanted to write my own understanding about the 2D implementation of water surface effects. Unfortunately, I have been dragging on for various reasons. Fortunately, some things have come to an end recently, and I have

Two stack implementation queue and two queue implementation stack　　Queuing (queue) FIFO linear table, stack (stack) advanced out of the linear table.Two stacks to implement a queuefa Yi Ideas:S1 is in the stack, S2 is out of the stack. Into the queue: directly pressed into the S1; Out queue: If S2 is not empty, the top element of the S2 is ejected directly, otherwise all the elements of S1 are

Pure PHP Implementation Timer Task (timer), PHP implementation Timers timer Timer tasks, common in Web applications, how to use PHP to implement timer tasks, there are roughly two scenarios: 1. Use the crontab command, write a shell script, invoke the PHP file in the script, and then execute the script on a regular basis, 2) with Ignore_user_abort () and Set_time_limit () to make the script run out of the

After more than three years of accumulation, I implemented addition, deletion, modification, and query based on XML configuration, established a basic system architecture, and used xml configuration (using structured XML documents to configure relevant information) allows you to add, delete, modify, query, and business processes. It allows developers to easily develop and meet customer needs, and supports system implementation and maintenance personne
