English: Terms and partial sums of 1 − 2 + 3 − 4 + · · · going out to the horizon.
  • The terms are indicated as black lines executing displacements to the camera's right, plus a constant displacement away from the camera.
  • The partial sums are where the terms end; they are indicated as black circles.
  • The action takes place on an infinite horizontal plane. The integers are located on the gray lines. The horizon is picked out by a bluish sky.
  • The camera type is rectangular perspective. Of course, it is placed over x equal 1/4 for symmetry.
Português: Termos e somas parciais de 1 − 2 + 3 − 4 + · · · dirigem-se para o horizonte.
  • Os termos são indicados por linhas pretas executando deslocamentos à direita da câmara, mais um deslocamento constante para longe da câmara.
  • As somas parciais estão onde os termos terminam; elas estão indicadas por círculos pretos.
  • A ação ocorre sobre um plano horizontal infinito. Os números inteiros estão localizados sobre as linhas cinzas. O horizonte é reconhecido por um céu azulado.
  • O tipo da câmara é de perspectiva retangular. Claro que, é colocado sobre x igual a 1/4 para a simetria.
