C++ :: 3D Graphics With Quaternion Data
Jul 7, 2014
So I've got a sensor (contains a gyroscope, accelerometer, and magnetometer) that outputs quaternion data. I'm looking to take that data and use it to display the rotation of my sensor in the form of some object on the screen. I've seen instances where programs use a cube, but I'm hoping to figure out a way to have a little more control over what the object I'm rendering is.
how to get started? Are there any software packages that might be able to accomplish this?

Just bought a new ST Micro iNEMO-M1 system, and am looking to have my code visually show me the rotation information. I've got a working C++ code which actively acquires data from the sensor, and I'm looking to extend that into some visual interface which will show me on-screen the position of the sensor.
I figure using rotation information in the form of quaternion data is the most useful (want to avoid the gimbal lock problems associated with Roll/Pitch/Yaw).
What would be the best method to visualize the rotation of my sensor in real-time?

I try to use quaternion to rotate one(and later more!) 3d-vectors in a general manner.
i read in wikipedia, that the general calculation goes with:
vector_rot = quaternion * vector * quaternion_compl.conj.
I used the class of irrlicht [URL] .... to do the calculations.
there is no premade function in this class to rotate vectors through this quaternions, so i just tried to it this way:
irr::core::vector3df v1(1,0,0);
irr::core::quaternion a1(2,3,4,6);
a1.normalize();
irr::core::vector3df result2(a1.X*v1.X*(-a1.X),a1.Y*v1.Y*(- a1.Y),a1.Z*v1.Z*(-a1.Z));
result2 should then be the rotated vector, but it does not work. i dont know how to explicitely write down the rotation specification in this topic.

I have a 3d Point in space. From this point I have vertices defind by(scale). I have a Quaternion representing the rotation of the object (lets say a block). So...
(1) I know the point in local and world space and can translate.
(2) I know the scale of the object and it's starting vertices intersections at zero rotation.
(3) I have the quaternion which represents the 3d rotation and can translate that to degrees and Eulers.
How do i find the exact points of the vertices after the rotation. (what I'm attempting to do is plot points from vertice to vertice all along the sides/top/bottom of the object.)I have looked at Matrix4 transformations and Quaternions and still do not understand how to find the vertices after rotation.

I use visual studio 2012. When I asked what I should use in order to put graphics into my program, I was told by the community that SFML works well. My only problem is that now I have SFML, where and how do I unpack it?

I'm new to c++ So I have a project to make. I need to make a cursor like an arrow that will move when inputs are given. e.g if input is given 500 spaces UP it will move up and so on. it should rotate as well like 45 degrees and so on. how to make this arrow WITHOUT USING GRAPHICS.

I have been learning Direct3D for a while now (DX11), and I ran into a bit of a dead end. I have Frank Luna's book on D3D programming, but I feel like I could find a better tutorial out there. I am at the point of writing the vertex shader (the first one he goes over)
Currently, I am using .fx files to write the shaders. Is that right?

I am new to grpahics progamming in/under Borland C. I have included the "graphics.h" header file but i am unable to take input on the screen. If I try to move my cursor to a specified position using gotoxy() function the pointer doesnt moves to the specified location and starts taking input at (1,1) coordinate.

I am trying to produce a image using GD graphics library. I can succesfully display my image, however I cant display this image along with a printf function too?
Code:
#include <stdio.h>
#include <gd.h>
int display_picture()
{
gdImagePtr gdImage = gdImageCreate( 50, 50 );
FILE *jpgFile = NULL;
[Code] ....
The picture displays but not hello.

Ive been experimenting with 3d graphics by using SDL only and lines to draw 3d shapes (no OpenGL or extension libraries, just pure math),
Ive used this page mainly to guide me on perspective projection but i have no luck [URL] ....
Ive been trying to draw a cube, but instead it gives me a mirrored dual triangular pyramids
This code here rotates the object as seen from the equations in this link: [URL] ....
double aX, aY, aZ;
for ( i = 0; i < model->qLength; i++ ) {
for ( j = 0; j < 4; j++ ) {
aX = model->quadArr[i].pointArr[j].x;
aY = model->quadArr[i].pointArr[j].y;
aZ = model->quadArr[i].pointArr[j].z;
[Code] .....
generally, i project it onto a 2d plane using: [URL] .....
double dx, dy, dz, dX, dY, dZ;
int bx, by, bX, bY;
for ( i = 0; i < model->qLength; i++ ) {
for ( j = 0; j < 4; j++ ) {
[Code] .....
I understand that my code is very messy and unoptimized, but im just concentrating on getting the core concepts to work with my code

I'm trying to create a GUI with Open graphics Libraries.I have made a basic GUI that exits the program or shows the instructions if a option/Polygon is marked (A bigger one is behind them)But what I'm trying to do now is the following:
0. Start the direct access on the desktop
1. Screen: Press any key to continue
2. Select one option
2.1 Option one: Go to the circuit selection menu
2.1 Option two: View the instructions (Cleared)
2.1 Option three: Exit the game (Cleared)
3. Select a circuit
4. Go to the car selection menu
5. Select a car and start the race
6. Pause menu if Spacebar has been pressed
From the pause menu:
6.1. Go to the main menu
6.2. Restart the race
6.3. Exit
I know that it is OpenGL, but what i'm looking for is C++.How I could do that? What I have cleared is with IF but I'm looking for better alternatives.

I'm trying to find the errors in my emulation of VGA VRAM concerning graphics modes.
(I'm testing it by doing plotting of all colors from x=0 to x=xsize-1 (where the color is relative, so 0=0 and xsize-1=maxcolor (in the case of 16 colors it's 15, etc.)))
VRAM Graphics management:
#include "headers/types.h" //Basic type support!
#include "headers/hardware/ports.h" //Basic PORT compatibility!
#include "headers/hardware/vga.h" //VGA data!
#include "headers/mmu/mmu.h" //For CPU passtrough!
#include "headers/hardware/vga_screen/vga_displaygeneration_crtcontroller.h" //For virtual width in bytes within VRAM!
[Code] .....

I have a college project which is a car racing game using C++ and the old-school graphics library BGI. After I draw the map and placed the objects(Car,obstacles,road's borders etc..)I added Sleep(); function to the function named Obstacles(); but the problem is, I can't move the car with the right&left arrows.a
Another problem,If I added a cleardevice(); command all objects disappears only the obstacles function keeps working. the Code is here:
char c;
do{
c = (char)getch();
if (c == KEY_LEFT) {
x = x - 10, x1 = x1 - 10;
} if (c == KEY_RIGHT) {
x = x + 10, x1 = x1 + 10;
[code].....
note: this is not the whole code, it's only a small portion of it, not a debugging question only need a hint how to fix it.

What i'm trying to do is load an image from my database create some graphics to it. probably just some lines and marks and save it back to my database. here's so far what I got.
for creating graphics:
} private void pictureBox3_MouseDown(object sender, MouseEventArgs e) {
draw = true;
} private void pictureBox3_MouseMove(object sender, MouseEventArgs e) {
if (draw) {
Graphics g = Graphics.FromImage(pictureBox3.Image);
[Code] ....
but the saving part doesnt work :( I think it only saves the image loaded to the picturebox but not the graphics created to it. how to merge it? i've tried to google it and found some sort of same cases but fails to make it work, something like converting it to bitmap.

In this project I need to develop few functions to work with graphics card. I work in minix and this is pretty rubbish.
I'm having an hard time to read a pixel map, or atleast to print it on my main function.
I have a read_xpm function, which is given, therefore, working.
Code:
char *read_xpm(char *map[], int *wd, int *ht)
Then I have a pixmap.h file which gives some examples of pixmap images that I can use as example:
Code:
static char *pic1[] = {
"32 13 4",
". 0",
"x 2",
"o 14",
"+ 4",
[Code] ....
The doubt is. I have a test_xpm function and I need to call this char array but this is so many pointers that I can't even figure out where I'm pointed to (?)
Code: int test_xpm(unsigned short xi, unsigned short yi, char *xpm[])
I tried something like read_xpm(xi, yi, *xpm[0]); but I'm guessing I need to index that array and run all those chars in order to show them.

How would you create a video game in c++? I'm not sure really how to display the graphics and set properties and do all that stuff. I don't have money to buy a book about so how do you?

How do you calculate the inverse view matrix?
Is that really just the inverse of the view/camera matrix?
Or is that something else?
I have seen articles online on the overall mathematical theory behind it but I am using the GLM math library and it has this nifty glm::inverse() function.
I was just curious if I can do a glm::inverse(ViewMatrix) and that would be correct.
