The Art of Innovation When we talk about Renderman, we also have to mention Pixar, the studio that makes animated films. Let’s take a look at the history of the studio, which was born out of the need to create real images in the digital world.
The history of Pixar shows that science and art go hand in hand in the world of film creation, so let’s find out what exactly Renderman is a tool for. Just like painting, the painter remembers the color, light and shadow of the objects he sees in his brain through constant observation of the things around him, and then relies on his hands to present the objects of the three-dimensional world on the canvas of the two latitudes, Renderman is such a set of tools, we tell him what objects are in the three-dimensional space, where the light source is, the position of the camera and the angle of observation of this space is. Rendering a picture is of course not enough, we need to make the viewer feel that the picture was taken with a real camera, then we need to simulate real world light and color in the computer world, and that’s what Renderman needs to do. After the model is built, we can output a scene description file that is compatible with the Renderman program, input this description file into Renderman, and we get a photo with real texture. Renderman is actually the specification and implementation of a series of external interfaces that take Rendering out of modeling for independent development, then any 3D modeling program that can communicate with Renderman through these interfaces can deliver the scene description to a renderer with a Renderman interface implementation to render the image.
