A |
|
|
| accuracy | A parameter enabling to define the degree of precision of the rendering quality | |
| ambient lighting | The intensity of light emitted by any light source | |
| animation | A rendering of successive positions of a product recorded in a simulation | |
| anti-aliasing | A graphic design technique that involves adding colored pixels to smooth the jagged edges of a graphic | |
| 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 | |
C |
|
|
| camera | A rectangular-shaped element with a lens used to specify the chosen viewpoint to take the image | |
| cylinder area light | An area light source with a cylinder shape used to simulate neons, for instance | |
D |
|
|
| 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 | |
| disk area light | An area light source with a disk shape used to simulate spot lights | |
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" | |
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 |
|
|
| part | A 3D entity obtained by combining different features | |
| photo-realistic | An image with a quality quite similar to a real image or a picture | |
| point light | A punctual illumination (like a bulb, for instance) emitting light isotropically, i.e. in all directions | |
| product | A 3D entity containing several components | |
| property | The attribute or characteristic of an object that defines its state, appearance or value | |
R |
|
|
| raytracing | A photo-realistic image 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 | |
| rectangle area light | An area light source with a rectangular shape used to simulate a rectangular spot light | |
| 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 | |
| roughness | The dullness of an object (it represents the size of the reflecting zone) | |
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 | |
| specification tree | An area of the document window reserved for viewing the design specifcations of a part, presented in the form of a tree structure | |
| specular lighting | The dullness of an object | |
| sphere area light | An area light source with a sphere shape used to simulate a light bulb, but in a softer and more realistic way than the point light does | |
| 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. | |
| sticker | An image that can be mapped onto a face of a product | |
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 | |
| turntable | A revolvable platform enabling to generate a sequence of images representing the model rotation around a user-defined axis | |
