Re: Is it possible to alter a texture in real time on a pixel basis?
You can also use the Irrlicht functions directly. Bascially - create an IImage and ITexture with same sizes and format. Work with the setPixel functions of IImage. Then as above use lock() on ITexture and lock() or getData on the IImage. Then copy the IImage data over to the texture. While that is ...

Is it possible to alter a texture in real time on a pixel basis?
I want to obtain the effect of a virtual screen on which I can draw pixel by pixel while the program is running. At first, I tried following this naive approach:
// The virtual screen is created, one pixel at a time
for (x=0; x<VIRTUAL_SCREEN_WIDTH; x++)
{
for (y=0; y<VIRTUAL_SCREEN_HEIGHT; y ...
// The virtual screen is created, one pixel at a time
for (x=0; x<VIRTUAL_SCREEN_WIDTH; x++)
{
for (y=0; y<VIRTUAL_SCREEN_HEIGHT; y ...

Where do I find an example where it's used?

How do I make objects attached to the camera never change their apparent size when I change the FOV?
I'm making a HUD for a space game. I'm taking inspiration from The Last Starfighter (see https://youtu.be/hafnDoApzpY?t=36 ), so the radar and attitude of the spaceship are represented by 3D spheres, attached to the camera node as children, which match the rotation of the camera.
