Hi! I was the founder and software architect at
[Solid Angle](https://web.archive.org/web/20180309005909/http://www.solidangle.com/about/)
(now part of [Autodesk](https://www.autodesk.com)) where I led the development of the
[Arnold Global Illumination Renderer](https://www.arnoldrenderer.com) and, along with my
awesome team, published a few papers on ray tracing and sampling.

Short Bio
===================================================

 Marcos is the founder of Solid Angle (now part of Autodesk, Inc) where he led the development of the Arnold path tracing renderer
which he has worked on for 23 years. Prior to that, he was a visiting Software Architect at Sony Pictures Imageworks, a visiting
researcher at USC's Institute for Creative Technologies under the supervision of Dr. Paul Debevec, and also consulted at various CG
studios around the world. He has co-produced audiovisual projects such as the short film "La Noria". In 2017 Marcos and his team
received an AMPAS Scientific and Engineering Academy Award for their work on Arnold, and in 2021 he received an Emmy Award. He is a
frequent speaker at SIGGRAPH, FMX and EGSR. His favorite sushi is Hokkaido uni.

 **En Espa&ntilde;ol:** Marcos Fajardo, ex-alumno de la Universidad de M&aacute;laga, es el fundador de Solid Angle SL (ahora parte
de Autodesk, Inc.) donde dirigi&oacute; el desarrollo de Arnold, un software de trazado de rayos para la renderizaci&oacute;n de
imagenes 3D en cine y TV. Arnold se ha usado en proyectos como *Gravity*, *Blade Runner 2049*, *Juego de Tronos*, *Pocoy&oacute;*,
y en multitud de pel&iacute;culas del universo cinematogr&aacute;fico de Marvel como *The Avengers*, *Iron Man 3*, o *Doctor Strange*.
Anteriormente, fue arquitecto de software en Sony Pictures Imageworks, investigador asociado en el Institute for Creative Technologies
de la Universidad del Sur de California junto al Dr. Paul Debevec, y consultor en varios estudios de producci&oacute;n 3D. En 2017,
Marcos y su equipo recibieron el Oscar de la Academia de Hollywood en la categor&iacute;a Cient&iacute;fica y de Ingenier&iacute;a por
su trabajo en Arnold, y en 2021 recibi&oacute; el premio Emmy de ingenieria de la Academia de Televisi&oacute;n. Mas recientemente,
Marcos ha coproducido proyectos audiovisuales como el cortometraje de animaci&oacute;n *La Noria*.

Old Projects
===================================================

* ![ ](images/raidovercoin-icon.jpeg width="96")[Raid Over Co&iacute;n](https://replit.com/@MarcosFajardo/Raid-Over-Coin?v=1): MSX-Basic videogame I coded back in 1987 running on an emulator via Replit (thanks to [LuisAFK](https://replit.com/@LuisAFK)).
<br>

* ![ ](images/povafx10-icon.jpg width="96")[POVAFX](https://web.archive.org/web/20011109205701/http://www.geocities.com/TimesSquare/2143/povafx10.html): POV-Ray with (simple) Atmospheric Effects, 1996. While POV-Ray 3.0 adds many similar effects, its point lights are fast and alias free (because of analytical as opposed to numerical sampling).  
<br>

* ![ ](images/skylight-icon.jpg width="96")[Monte Carlo ray tracing experiments](http://www.3dluvr.com/marcosss/indexb.html): Some of my first path tracing results which I shared in 1999. This code then evolved into [RenderAPI](http://www.3dluvr.com/marcosss/canada.html) which later became [Arnold](http://www.3dluvr.com/marcosss/index.html).
