3d character modelled in Blender with the plug-in ManuelbastioniLAB 1.5.0. MB-Lab (previously ManuelbastioniLAB) is a free and open-source plug-in for Blender for the parametric 3D modeling of photorealistic humanoid characters.
Real-world subsurface scattering of light in a photograph of a human hand Computer-generated subsurface scattering in Blender. Subsurface scattering (SSS), also known as subsurface light transport (SSLT), [1] is a mechanism of light transport in which light that penetrates the surface of a translucent object is scattered by interacting with the material and exits the surface potentially at a ...
A normal shader (left) and an NPR shader using cel-shading (right). Non-photorealistic rendering (NPR) is an area of computer graphics that focuses on enabling a wide variety of expressive styles for digital art, in contrast to traditional computer graphics, which focuses on photorealism.
LightWave comes with a nodal texture editor that comes with a collection of special-purpose material shaders. Some of the types of surface for which these shaders have been optimized include: general-purpose subsurface scattering materials for materials like wax or plastics; realistic skin, including subsurface scattering and multiple skin layers
Several different, and often specialized, rendering methods have been developed. These range from the distinctly non-realistic wireframe rendering through polygon-based rendering, to more advanced techniques such as: scanline rendering, ray tracing, or radiosity. Rendering may take from fractions of a second to days for a single image/frame.
Bump mapping is a technique in computer graphics to make a rendered surface look more realistic by simulating small displacements of the surface. However, unlike displacement mapping, the surface geometry is not modified. Instead only the surface normal is modified as if the surface had been displaced.
Sophisticated applications allow savvy users to write custom shaders in a shading language such as HLSL or GLSL, though increasingly node-based material editors that allow a graph-based workflow with native support for important concepts such as light position, levels of reflection and emission and metallicity, and a wide range of other math ...
A cel shader is often used to mimic the style of a comic book or cartoon and/or give the render a characteristic paper-like texture. [1] There are similar techniques that can make an image look like a sketch , an oil painting or an ink painting .
