Irrlicht Engine

Hi,

I want to rotate an object about a pivot point.
Basically I want to set a point based on which the object needs to be rotated.

But,
node->setRotation rotates an object which is not expected.

Please let me know how to do it.

regards,
Kguru

Thanks. I ll put my code in tag in future.

I calibrate the position of the IR dots to the screen co-ordinates.
My screen co-ordinates X: -15 to 15 ; Y : -10 to 10 and Z: -18 to +18.

Normally Raw X and Raw Y range from (0.0 - 1.0) and I calculate the depth using 1/(xL - xR) ; xL - position seen by the left wiimote and xR - position seen by ...

Edited the code section.

Is there a way in Irrlicht to find the rotation using 2 3D points.

I am using wiimote for my project and I calculate the 3D position of 2 IR led dots.

I use these 2 dots to find the rotations in 3D. Is there an easy way in Irrlicht to do this? (quaternions or sth ...

I try to set the position of objects in the scene.

Its not the same if I try to render it with DirectX shader. My hardware supports directx shader.

Hi,

I use to program in my lab PC.

But I tried to run the same program in my laptop using GLSL shader.
It says GLSL shader not available.

Should I install any software for this or is it a hardware issue?
Also the alignment in the scene is changed. Please let me know what to do?

I did the comparison like this and it works. Thanks all for the help.

stringw login = guienv->getRootGUIElement()->getElementFromId(GUI::GUI_LOGIN_BOX, true)->getText();
stringw pwd = guienv->getRootGUIElement()->getElementFromId(GUI::GUI_PW_BOX, true)->getText();

if(login == L"loginname ...

Thanks a lot. The event is being caught it works perfectly.

But still I could not evaluate the text in the login and password box.

I tried to print what getText() returns and it always returns
loginname = 049BF9D0 and the check fails.

I entered "loginname" and "pw" in the login and password ...

Hi,

I created a login form and added login and password edit boxes.

I have a couple of issues.

1. I have to check the user name and password on the editbox when I click "LOGIN" button. I dont know how to do the event receiver.

I tried this,

switch(event.GUIEvent.EventType)
{

case EGET ...

Hi,

Is it possible to add a login dialog for the game using Irrlicht GUI.

Please help me out.

Hi,

I have created a new font.

But how to apply that font to the text displayed in GUI Menu and Messge Box. I am not able to change its default font.

I tried guienv->getFont(<My File>);

<My File> - I tried giving the bmp file and the xml file. But both didnt work.

Thanks devsh.

I saw your Ninja Project. Looks interesting. I am using IrrNewton in my code.

Please let me know if I can join you in the code.

// Projection Transformation

glMatrixMode(GL_PROJECTION);
glLoadIdentity();


glFrustum( (-H_SCREENEDGE-my_camera.eye_pos[COORD_X]) * nearplane/my_camera.eye_pos[COORD_Z] * 0.3, // left

Hi andytheb,
Please let me know what is the value of d_perp.

The example code uses OpenCV. Is there a code that uses Nintendo Wiimotes for headtracking.
I am having hard time setting up the projection matrix while using Irrlicht.
I have a working code in OpenGL.

Thanks,
