Rasterizer: what does it do?

Game Engine Game Engine Support and Discussion

OK, in the profile of a game, there’s a section called “Rasterizer”. What does this encompass? I’ve noticed that in my chess game (the related topic should be around here) it flies up to 45%. What does the rasterizer do?

it does the work with the screen, i.e. mouse functions(Rasterizer.showMouse, for example) and things to get window size…

…i think…

i’m pretty sure this is right, but i may be wrong on some things

rasterizer is the graphics renderer, it rasterizes (=draws) the triangles.

5

so it’s the drawer

6

So a higher rasterizer % means there’s more polys in the scene?

7

Rasterizer handels all of the rendering of a scene, so too many polys, too high res textures, and those kinda things are what slow down the rasterizer, and if the rasterizer is having a hard time rendering the scene fast enough, then your framerate slows.

orge intagration will bring that value way down like bullet did for physics

This are percentages!
It only shows the balance of the game. A rasterizer of 45% means the engine spends 45% of time for the rasterizer. That does not necessarily mean it is to much.

If your framerate drops you can use these numbers to determine where a bottleneck could be and concentrate on this. Keep in mind everything slows done, but removing big gaps makes more sence then little gaps.

Also the values can change on different hardware.
