I'm having trouble understanding things in directx for vb. Whats a renderloop and a device exactly? A device is a way the software communicates with the video card?? I'm kinda confused.

Quote:Whats a renderloop

Let’s say you have a 3D interactive game. It’s not like you have a photo that looks the same 10 years for now. Whatever is being shown on the screen needs to be constantly updated for changes. This repetition is done in a loop. The act of taking the items in the game and showing them as an image on screen is called rendering. Hence a renderloop, where the screen is repeatedly drawn as necessary over and over.

More like an API abstraction that represents some capability of hardware like graphics or audio or input. Instead of worrying about the specific hardware in the computer, you simply rely on a device to deal with the details. It manages the hardware, you just use it to do what you want.
