A skybox is a method of creating backgrounds to make a video game level appear larger than it really is. [1] When a skybox is used, the level is enclosed in a cuboid.The sky, distant mountains, distant buildings, and other unreachable objects are projected onto the cube's faces (using a technique called cube mapping), thus creating the illusion of distant three-dimensional surroundings.
Physically based rendering (PBR) is a computer graphics approach that seeks to render images in a way that models the lights and surfaces with optics in the real world. It is often referred to as "Physically Based Lighting" or "Physically Based Shading". Many PBR pipelines aim to achieve photorealism.
For instance, Chaos Corona 8 (2022) includes Cosmos (a library of curated render-ready models with comprehensive materials, such as furniture, trees, cars, and people, as well as HDR sky images); materials library and materials editor; [9] conversion tools that simplify import of scenes, lights, objects, and materials from V-Ray, Mental Ray ...
The ambient occlusion map (middle image) for this scene darkens only the innermost angles of corners. In 3D computer graphics, modeling, and animation, ambient occlusion is a shading and rendering technique used to calculate how exposed each point in a scene is to ambient lighting. For example, the interior of a tube is typically more occluded ...
Version 7.0 brought Multi-Layer Rendering, Image-Based Lighting, Raytrace Sky Maps and Rigid Body Dynamics. The version, 8.0, added Photon Mapping, Fast soft shadows, area light, Quadratic light drop-off, EXR and 16bit image input support, Displacement Sea Level, new Weight maps tools, much workflow enhancement and Renderama improvements.
A distinction is made between real-time rendering, in which images are generated and displayed immediately (ideally fast enough to give the impression of motion or animation), and offline rendering (sometimes called pre-rendering) in which images, or film or video frames, are generated for later viewing. Offline rendering can use a slower and ...
Current generation gaming systems are able to render 3D graphics using floating-point frame buffers, in order to produce HDR images. To produce the bloom effect, the linear HDRR image in the frame buffer is convolved with a convolution kernel in a post-processing step, before converting to RGB space. The convolution step usually requires the ...
Environment maps can be used to render 3D objects and virtual panoramic scenes. Many personal weather station online cameras around the world upload fisheye images of the current local sky conditions as well as a previous day time-lapse sequence with climate conditions such as temperature, humidity, wind and rainfall amounts.
