How are Computer Graphics (CG) Rendered?

Oscar de la Hera Gomez
A flower that represents spatial computing with the text "How Computer Graphics<br />(CG) are Rendered" beneath it.

An overview of how computer graphics are rendered in augmented reality (A/R), virtual reality (V/R), mixed reality (M/R) and spatial computing.

A diagram of a render pipeline with 6 stages: input, vertex shader, primitive assembly, rasterization, fragment shader and frame buffer.

An example of a render pipeline.

A computer renders environments, scenes and objects (i.e. geometries or models) through software that passes information through a render pipeline that:

  • Takes in vertices (i.e. the input).
  • Assembles and projects the vertices into space through a vertex shader.
  • Converts the vertices into a series of dots and lines (i.e. primitive assembly)
  • Converts the primitive assembly into a series of pixels (i.e. rasterization).
  • Applies color and styling to the pixels, dots and lines through a fragment shader.
  • Presents the visual on a screen through a frame buffer.

An image that shows how vertices become edges, which define faces, which create polygons that have surfaces and combined, produce a model or a geometry.

How models, geometries are constructed.
