rasterisation

rendering 2d image step 4

fragment processing

vertex processing step 1

compute attributes of vertices

vertex processing step 2

perform coordinate transformations

vertex processing step 3

calculate projection of the scene

rasterisation

the process of converting grouped vertices into fragments

fragment

a 3d projection of a pixel potentially visible in the image

what information does a fragment carry?

colour, location, distance from camera

fragment processing step 1

eliminate hidden surfaces

fragment processing step 2

alter colour of fragments

fragment processing step 3

blend pixel colours (translucency)

vertex

a 3d point in world coordinates

primitive

a point, line, or triangle built from vertices
