modify single pixel(s)

[fsteff]

Hi,
I´m actually working on a simple voxel raycasting engine.
I need to set every single pixel seperate.
I actually use SDL for this, but it is much too slow for this -.-
Is there a possibility in SFML to do this faster? I need about 30 fps in full hd.
If not, can you tell me how to do this?

The fastest solution is to work on your own array of pixels in system memory, and then upload it to the graphics card with sf::Texture::update and draw it with a sprite.
