| Yerm said: gonna need to deconstruct that a bit. so you want a game to run at 30fps - for specifically talking about the GPU, it first has to render the environment. first the geometry is loaded, then the textures, then the shadows, and finally post-processing and anti-aliasing are added on top of the final image. but from then on, its done. when your character moves through a 3D environment, the only things that need to be updated are the Player Character and the camera, which is usually derivative of the player. the post-processing and anti-aliasing are the only things that need to be updated every frame, because they act as a filtering layer on top of the graphics |
That doesn't sound right.... or am I missing something?
This makes it sound like after the first frame is created the GPU doesn't have much else to do for all subsequent frames. So what so what happens when there is an expolsion? a building collapses? some NPCs r even the player (if third person) appears on screen.... with every new frame not only are all of these things in a new position, but animation means that they may also look different.
Doesnt that mean that the entire scene is redrawn with every frame?
I know there are things that deosnt have t be drawn from scratch every frame but.......
