Numerics |
|
|
| 3D texture | An image defined for every point of the 3D space and thus, seeming to be sculpted in a material block | |
A |
|
|
| accuracy | A parameter enabling to define the degree of precision of the rendering quality | |
| area light source | A source of light similar to ordinary light sources and designed to create a soft, and thus more realistic, lighting. Compare light source | |
| attenuation | The action of lessening illumination | |
B |
|
|
| bump mapping | A technique based on a texture and introducing apparent surface deviations from its original shape (such as waves of the sea or pleated leather) | |
C |
|
|
| camera | A rectangular-shaped element with a lens used to specify the chosen viewpoint to take the image | |
| caustics | Light patterns formed on other objects by the reflection or transmission of light striking a reflective or refractive surface | |
D |
|
|
| depth of field | A visual effect making objects that are not in focus appear blurry, thus giving a sense of depth to the image. | |
| diffuse lighting | The intensity of light diffused by the object when lit by light sources | |
| directional light | A light coming from a given direction (like the sun, for instance) generating constant intensity parallel lighting | |
E |
|
|
| environment | A geometrical element, either rectangular, cylindrical or spherical, used to simulate interior as well as exterior scenes | |
F |
|
|
| Final Gathering | A method used to compute light energy on any surfaces surrounding an object in the scene. Synonym: "indirect illumination" | |
G |
|
|
| global illumination | A simulation of indirect illumination of objects by diffuse interreflection of light coming from diffuse surfaces | |
| glow | A visual effect generating a halo around bright pixels of the rendered image. | |
L |
|
|
| light source | A source of light illuminating the object to be rendered | |
M |
|
|
| mapping | A method used to apply an image onto an object in order this object acquires a surface texture | |
| material | An object that can be mapped onto a geometry to simulate visually and physically the components an object is made of (e.g. wood, stone, etc.) | |
P |
|
|
| photon | An energy particle emitted in the scene by a light source | |
| point light | A punctual illumination (like a bulb, for instance) emitting light isotropically, i.e. in all directions | |
R |
|
|
| raytracing | A rendering technique producing photo-realistic images resulting from the calculation of the path of light reaching the product from various angles. Each pixel is created by calculating the behavior of a number of rays from these different points over the area covered by that pixel | |
| reflection | A light wave returned from a surface | |
| reflectivity | The ability to reflect light | |
| refraction | The degree of light passing obliquely through an object | |
| rendering | A photo-realistic drawing of three-dimensional objects | |
S |
|
|
| scene | A reusable configuration enabling to put models on stage using cameras, light sources, environments, turntables | |
| shooting | A set of parameters used to define a rendering | |
| specular lighting | The dullness of an object | |
| spot light | A light source emitting the light isotropically inside a cone of influence determined by the privileged direction of illumination (forming the axis of revolution) and the angle that the edge of the cone forms with this axis. | |
T |
|
|
| texture | An image that can be mapped onto a geometry | |
| transparency | The degree of transparency of an object. The object transparency defines its property of transmitting light so that elements lying beyond are seen | |
