Back in 2020 I wrote a blog post Renderman24 Will Support Blender,at the end of which I documented my intention to purchase a commercial version of Renderman. after more than a year, I realized my idea, configured myself with an image workstation, purchased a commercially copyrighted Renderman, and most importantly, I also purchased a set of EIZO CG319x monitors for myself. The initial reason for preparing all this was mainly because of the rise of web 3.0. I envisioned a one-person freelance career, because the film industry is created through a very large group of people, and it is very time-consuming for one person to complete a live-action film or an animated feature film, or even a short film, independently, because there are many technical as well as artistic stumbling blocks in front of you, and you have to overcome them little by little to complete every detail of the film. Then I thought about the possibility of using the machine’s algorithm to set up the characters’ environment, to generate life and environment in the computer’s world, which is called modeling and animation and scene production in conventional film production. Dare to imagine if the computer can complete these creative processes, such as animal jumping and running, model materials, keying, human walking, we are no longer through the drawing of key frames, debugging materials, manual green screen keying, but through the computer’s learning of the real world to actively explore these key frames, to achieve the simulation of real-world object materials, the precise keying of the characters in the picture, then it seems that a person It is no problem to create a wonderful movie. Of course, this is just an idea, and the technology is not yet so sci-fi. ...

Reference Renderman 24 For Blender Doc Cameras in Blender Depth of Field in Blender Depth of Field (DOF) is a photographic technique used to convey scale (size) and areas of interest in a composition. Clever usage can lead a viewer to certain parts of your image and increase photorealism by correctly mimicking a real-world lens. RenderMan provides controls for realistic and compelling images with depth of field. There are also options that are non-physical but great for creating art-directed imagery. ...

Reference Renderman 24 For Blender Doc Rendering in Blender Integrators in Blender Integrators take the camera rays and return results to the renderer. For the main integrators these are estimates of the light energy (radiance) from the surfaces seen from the outside along the rays. These main integrators are responsible for computing the overall light transport, that is, light that travels from a light source through your scene from object to object (or through objects and volumes) to reach the camera. Interior integrators assist in specialized cases by handling the light within surfaces or volumes. We provide three main production quality integrators, though users can substitute their own. ...
