He said that the city resembles other Maya cities from the same period, but there are “certain peculiar features.” Šprajc and his team found three plazas complete with large buildings and a ball game field. Maya civilization is best known for its pyramid temples and impressive stone structures that have been found across southern Mexico, Guatemala, Belize, Honduras and El Salvador. “When we got there we saw that the buildings were truly massive,” he said. Unused tracks and roads that got them fairly close to the site, but the researchers had to hack their way through thick jungle, using machetes and chainsaws to cut down trees and slash through other vegetation to reach what Šprajc describes as a “major site.” While LiDAR revealed the location of structures, archaeologist Ivan Šprajc - a researcher at the Slovenian Academy of Sciences and Arts (ZRC SAZU) - still faced an enormous hurdle when he and his team went to survey the area. “When we see the (LiDAR) images, we can see that there’s something amazing the real discovery happens after a lot of investigation and exploration,” said Fernandez-Diaz, who is also the co-Investigator at the National Center for Airborne Laser Mapping. Juan Fernandez-Diaz examines maps on his computer. ![]() It was all in a day’s work for Juan Carlos Fernandez-Diaz, an assistant professor in civil engineering at the University of Houston, who spotted the city in March during an airborne archaeological survey of the area.įor the past decade, he’s been a trailblazer in the archaeological application of LiDAR, airborne light detection and ranging equipment that can find structures obscured by dense tree canopies and other vegetation - relics that in some cases reveal traces left by a lost civilization.Īrchaeologists subsequently surveyed the site, which they’ve named Ocomtun, for six weeks in May and June and found 50-foot-tall (15.2-meter-tall) structures resembling pyramids, pottery and engravings that they believe date back to between 600 and 900 AD - known as the Late Classic Period in the Maya Civilization. You might now need to re-adjust your light intensities and temperatures, along with any Dome Light settings to re-compensate for the adjustment of moving to the ACES color space.Three four-hour flights high above the jungles of Campeche on Mexico’s Yucatan Peninsula exposed a hidden gem on the ground below: a lost city that was likely abandoned more than 1,000 years ago.Once pressed, the Texture Manager will now go ahead and convert all your color maps (diffuse, albedo, etc) into the ACES color space. Open RenderMan's Texture Manager from either the RenderMan shelf or menu and next to the Parse Scene button, you will now see a new Refresh all Textures and Re-Parse the scene icon.With your project loaded in Maya, select the ACES1.2 config from the OpenColorIO parameter in the Features tab within the Render Settings.If you wish to pick up an older Maya project and re-render it using ACES, here are some guidelines. Whether you render within IT, Maya's viewport, or Maya's RenderView, you are now rendering within the ACES color space.Ĭonverting an older Linear Maya project to ACES.You are now working with ACES-calibrated light temperatures and intensities, so feel free to increase the values higher to see one of the main visual benefits of ACES.Based on the rules defined, the Texture Manager handles all the conversions for you. This is also the same for when you insert an HDRI map into the PxrDomeLight or when working with Normal or Bump maps.For instance, if you insert a Diffuse or Albedo color linear sRGB map into the Diffuse parameter of a PxrSurface, the Texture Manager will not only convert it to RenderMan's preferred file format (.tex) but will also automatically handle the color conversion to the ACES color space at the same time. When working with textures, RenderMan will handle all the conversions needed to get your textures into the ACES color space.If you are rendering within Maya's viewport, you simply need to restart your interactive render session. If RenderMan's Image Tool is already open from a previous Linear project, you have to close and re-open IT, to ensure you are now rendering within the new ACES color space.When starting a new project, you'll need to select the ACES1.2 config from the OpenColorIO parameter in the Features tab within the Render Settings.When starting a fresh new project, there are a number of steps you need to do to get up and rendering with ACES within RenderMan. ![]()
