Physical Incarnations

Data flows “downstream” from stage to stage.

Most operations in the application/scene stage and the early geometry stage of the pipeline are done per vertex​.

Culling and clipping is done per triangle​.

Rendering operations are done per pixel​ .

Space

Model Space where each model is in its own coordinate system, whose origin is some point on the mode

World Space where models are placed in the actual 3D world, in a unified world coordinate system​ (OpenGL API doesn’t have)

View Space (Camera Space) in this space, the view camera is positioned by the application (through the graphics API) at some point in the 3D world coordinate system, if it is being used

*View Frustum & View Volume​ 

Clip Space similar to View Space, but the frustum is now “squished” into a unit cube, with the x and y coordinates normalized to a range between –1 and 1,
and z is between 0 and 1, which simplifies clipping calculations (x, y and z coordinates by a special w value)

*w value: a scaling factor

Screen Space where the 3D image is converted into x and y 2D screen coordinates for 2D displa​y (z and w coordinates are still retained by the graphics systems for depth/Z-buffering and back-face culling before the final render​)

Example Several pieces of Lego. Snap them together and make some object. Individual pieces of Lego as the object’s edges. (Vertices exist where the Legos interconnect.) The origin of the model space coordinates could be the lower left near corner of the object, and all other model coordinates would be measured from there. Move this object around a room. The Lego pieces’ positions relative to one another remain constant (model space), although their coordinates change in relation to the room (world or view spaces).

+) it’s better to write “for n in range(1000):” in line 3-5 cause it’s just keep putting new cubes to the array
