I. What is Pre-rendering? Pre-rendering is a process in computer graphics where images or animations are generated in advance, rather than in real-time. This means that the final output is calculated and stored before it is needed, allowing for quicker playback and smoother performance. Pre-rendering is commonly used in special effects for films, video games, … Read more
I. What is Matte Extraction? Matte extraction is a technique used in the field of visual effects to separate elements of a scene based on their color or luminance values. This process allows for the isolation of specific elements within a shot, such as actors or objects, so that they can be manipulated independently from … Read more
What is Rain? Rain is a type of precipitation that falls from clouds in the form of water droplets. In film and television, rain effects are often created using a variety of techniques, such as using sprinklers or hoses to simulate rain falling from the sky. Rain effects can add drama and atmosphere to a … Read more
I. What is Normal Mapping? Normal mapping is a technique used in computer graphics to simulate intricate surface details on 3D models without increasing the polygon count. It involves the use of a texture map called a normal map, which stores information about the direction that each pixel on the surface of the model is … Read more
I. What is Subsurface Scattering? Subsurface scattering is a phenomenon in which light penetrates the surface of a translucent or semi-translucent material, such as skin, wax, or marble, and is scattered beneath the surface before being reflected back out. This effect is responsible for the soft, realistic appearance of these materials when illuminated, as it … Read more
I. What is Front Projection? Front projection is a special effects technique used in film and television production to create realistic backgrounds and environments for scenes. It involves projecting images onto a screen or surface in front of the actors, allowing them to interact with the projected images as if they were real. Front projection … Read more
I. What are Tracking Markers? Tracking markers are physical objects or patterns that are placed on objects or actors during filming to assist in tracking their movement in post-production. These markers are typically small, high-contrast objects that are easily recognizable by tracking software. By tracking the movement of these markers, visual effects artists can accurately … Read more
What is keying in special effects? Keying is a technique used in visual effects and post-production to remove a specific color or range of colors from an image or video footage. This process allows for the insertion of new backgrounds, objects, or characters seamlessly into a scene. Keying is commonly used in film, television, and … Read more
What is a shader? A shader is a computer program that is used to determine the final appearance of a pixel or vertex in computer graphics. Shaders are commonly used in 3D rendering to create realistic lighting, shadows, and textures in video games, movies, and other visual media. Shaders can be written in various programming … Read more
I. What are Reflective Surfaces? Reflective surfaces are materials or objects that have the ability to reflect light and create a mirror-like effect. These surfaces can be found in various forms, such as mirrors, glass, metal, water, and even certain fabrics. When light hits a reflective surface, it bounces off at an angle, allowing us … Read more
