Normal mapping. Normal mapping used to re-detail simplified meshes. Normal map (a) is baked from 78,642 triangle model (b) onto 768 triangle model (c). This results in a render of the 768 triangle model, (d). In 3D computer graphics, normal mapping, or Dot3 bump mapping, is a texture mapping technique used for faking the lighting of bumps and ...
On the other hand, script-based primitive modeling is not always a practical method to create certain objects, such as realistic characters or complex man-made artifacts like cars. Those objects can be created first in mesh-based modeling applications such as Wings 3D and Blender, and then they can be converted to POV-Ray's own mesh format.
Blender is a free and open-source 3D computer graphics software tool set that runs on Windows, MacOS, BSD, Haiku, and Linux. It is used for creating animated films, visual effects, art, 3D-printed models, motion graphics, interactive 3D applications, virtual reality, and, formerly, video games.
Texture mapping. Mapping a two-dimensional texture onto a 3D model. 1: 3D model without textures 2: Same model with textures. Texture mapping[ 1 ][ 2 ][ 3 ] is a method for mapping a texture on a computer-generated graphic. "Texture" in this context can be high frequency detail, surface texture, or color.
UV mapping. The application of a texture in the UV space related to the effect in 3D. A representation of the UV mapping of a cube. The flattened cube net may then be textured to texture the cube. UV mapping is the 3D modeling process of projecting a 3D model's surface to a 2D image for texture mapping. The letters "U" and "V" denote the axes ...
Materials and textures are properties that the render engine uses to render the model. One can give the model materials to tell the render engine how to treat light when it hits the surface. Textures are used to give the material color using a color or albedo map, or give the surface features using a bump map or normal map.
The Utah teapot (1975) has a "hole" in it so it has a genus greater than zero. The Cornell box (1985) tests lighting and rendering. A 3D-printed reproduction of Stanford dragon (1996) physical model, made through rapid prototyping. Suzanne (2002) with wireframe. Spot (2012) shown homeomorphic to a sphere.
In the field of 3D computer graphics, Multiple Render Targets, or MRT, is a feature of modern graphics processing units (GPUs) that allows the programmable rendering pipeline to render images to multiple render target textures at once. These textures can then be used as inputs to other shaders or as texture maps applied to 3D models. Introduced ...
