I do this because I want to transform the .x format into xml... The "frame" data structure can contain other frames, and a name for the frame and a transformation. For example:
I know the above won't compile. But am I on the right track to implement data structures this way using linked lists? about directx, I'd like to ask is the .x format implemented with a tree structure rather than linked lists.
I am because I don't know what to use OpenGL or DirectX? I heard some people saying I can use both. How is this? What is better for online games? And when I choose I will need some tutorials too ....
So a long time ago I messed around with DirectX but I don't remember where it gets placed by default. I want to just get rid of the SDK and get the up to date version of it.
I have a problem with implementing Shadow Mapping into a project I am working on. I am very much new to shaders and I have been given a Shadow Mapping shader to implement and understand. I have mostly got my head round the concept and the code but I can't figure out why its not working.
As I understand it the main steps to follow are;
1) Render the scene from the POV of the light - this is done in ShadowMap::SetUpDepthRender where the view and projection matrices are passed to the shader.
2) Render all objects in the scene - this creates a shadowmap (depth map) via the shader.
3) Reset the view and projection matrices to that of the camera - done in ShadowMap::SetUpSceneRender.
4) Render the scene objects once more appling the depth map to them via the second pass of the shader.
The problem Im having is that I have a stripe of light running diagonally across the screen. It passes through the point of the spotlight that I am mapping for. I believe this is the shadowmap being applied to the scene however I could be wrong?
Below is the code in the ShadowMap class used for setting the fx file.
For a 2d platform game. As title says. I want to see the bounding box that I have created to work with de-bugging, I have the bounding box set to the edges of my sprites to use with collision. How do I show the outline of the bounding box?
I found that the program works when using these values for the rows and columns:
Rows = 2; Cols = 2;
Using any other value gives the error mentioned above. It displays a small flat surface where I want it to, but I am trying to have a large enough surface to use as a ground (like 100 x 100).
I am working on a project in which we capture a video using DirectShow samples. I want to know whether it is possible to capture a video with No noise, No interference etc. in other words, we want to capture High Quality (HD) video using DirectShow.
Is there any sample defined in DirectShow using which we can capture HD video.
I'm trying to learn how to implement vectorization. Lets say I have this an array like this.
Code: int Array[10] = { 3,4,5,3,4,5,6,7,8,9};
If I traverse through the array and preform some simple calculation like adding numbers, how would I go about vectorizing this feat? For example if I want to add numbers, .
An example, add element at index 5,6,7 to element with index 1.
I have to make a prgrama using the C programming language that is able to read several lines of commands entered by the user and interpret it as a command to run.
I have to implement the following command:
a) Command generic - program should be able to read any one command and execute the same command on the operating system through primitives for implementing generic processes (eg "ls-l/etc").
for (int i=0;i<number;i++){ printf("enter %d th string::",i+1); scanf("%s",str[i]); }
Above, I have a little snippet of a code that I'm trying to figure out. I don't really understand how to implement 2d arrays in C that well. But, I mostly want to know is how and where the strings are being stored, especially with the code below.
Code: for (int i=0;i<number;i++){ printf("enter %d th string::",i+1); scanf("%s",str[i]); }
I know that it's asking the user to enter strings, which will be stored into the 2d array. I just don't understand how it's being stored. Will it be placed in the 1st column or 2nd row or something?
I'm trying to implement the flocking algorithm in C++. I've tried to implement it myself by making all the particles 'home-in' on the player. When 2 particles then collide within their larger bounding boxes they home-in to each other. And when the 2 particles are actually touching they repel each other until they are outside of their bounding boxes and find another particle to home-into.when I run my application the particles all home into the player and come to a stand still along the Y-axis above the player.
All the particles in question are stored in a Vector, with a pos and velocity.
for(int i = 0; i < swarm.size(); i++) { for (int j = 0; j < swarm.size(); j++) { if (swarm.at(i)->getParticleModel()->getPosition().x < gameObjects.front()->getParticleModel()->getPosition().x) { if (swarm.at(i)->getParticleModel()->getTouching() == false)
Ok so i am coding in WPF i was coding just fine and im trying to implement a browserDialog
Here is the class
The issue i am having is in the DialogResult.Cancel This is the issue i receive 'System.Nullable<bool>' does not contain a definition for 'Cancel' and no extension method 'Cancel' accepting a first argument of type 'System.Nullable<bool>' could be found (are you missing a using directive or an assembly reference.
I'm trying to implement the Merge-Sort algorithm. I only had the pseudocode for it and have some problems coding this into C.
I have only covered pointers recently and I tried using them, which did not work. I started with the code for the merge algorithm and only used a 10 element array, which was already divided into two sorted subarrays:
Code: #include <stdio.h>#include <stdlib.h> int main() { int a[5]={1,5,6,10,13}, b[5]={4,8,9,10,14},c[10], *i,*j,k;
[Code].....
This is the result that I get:
Code: 1 4 5 6 8 9 10 10 13 0
So I think the problem occurs because in the second to last loop i is incremented again, but the end of the array is already reached, and the compiler has no element a[6] to compare with *j in the last run of the loop. Is there generally a better way to implement Merge?
I am starting to use contiki and learn c programming for my summer internship. I have to calculate the mean of the ongoing process of refrigerator power. I made the code like this
Code:
#include <stdlib.h> #include <stdio.h> #include <homadeus/processes/fridge_process.h> #include <homadeus/devices/78M6610.h> #include <homadeus/utils/utils.h> float global_variable; int current_state = 0; //down =0, up =1
[Code]....
How it gets the value of power is handled already. Every one second, it will display the power consumed (get_instant_power()). I don't know how to start and end the sample numbre. If I start by 1 then how should it be until? Also, is it possible if I store the power in array to accumulate?
I'm attempting to write the maximal clique algorithm for use with an adjacency matrix.I'm following a video which explains how to code and implement the algorithm using python. I want to write it for c++. URL....I'm currently trying to code the powerset function at 2 minutes into the video. I'm not sure if I should be using arrays or not.
So far I have coded the below but I dont know how to return an empty array inside an empty array (when the elts list is of size 0). I wrote an isEmpty function for the array since I cant use len(elts) like in python.
The code should use either an array/list/vector that we call 'elts' (short for elements). Then firstly, it should add the empty list [], then the rest of the power set (all shown in the video).So for example, in the case that elts = [1,2,3,4], my code should return:[ [],[4],[3],[4,3],[2],[4,2],[3,2],[4,3,2],[1],[4,1],[3,1],[4,3,1],[2,1],[4,2,1],[3,2,1],[4,3,2,1] ]
I have problems when implementing the IDIV Instruction in gcc assembler, the program has compiled ok, but when executing function that imparts the asm codes which contained the IDIV instruction the error box immediately appeared announcing that it should terminates the program quickly.
The following is the complete listing of the program that I just been working on it:
#include <iostream> #include <cstdio> #include <cstdlib> using namespace std; signed long divider(signed long num, signed long divisor); int main(int argc, char* argv[]) { signed long dn0,dn1,dn2;

I compiled it with DevCpp 4.9.9.2, and I had tried on CodeBlocks, in CodeBlocks I made used the int64_t type but still it could not works more..
Design a C++ Program to implement the following functions:
a.)the function for bubble sorting : int bubblesort(int*a,int size). b.)the function for merge sorting : int mergesort(int*a,int size). c.)the function for generating array of random elements: int generate(int*a,int size) which calls the function rand() in c++. d.)Test both bubble sorting and merge sorting with 10,100,1000,10000,100000 and 1000000,4000000 integers.
The integers are from the array generated by part c).calculate the time spent in calling each sorting.you may use a function in <time.h>to get the current time. Draw curves to compare the speed performance between the two functions. The merge sorting algorithm implementation must use recursion. you are expected to define a global array for holding result from merging two arrays.otherwise,it may cause a lot extra money in recursion.
Hint 1:use the following format to calculate the time cost for bubble sort.
{…….. Time1=Get the current time(call a function in <time.h>); Bbblesort(….) Tme2=Get the current time(call a function in <time.h>); Time_cost=the difference between time 1 and tim2; ……. } Print your program and test results
