Thermally processed material is usually totally amorphous, [7] and as a result is highly transparent to visible light, with better light transmission than many kinds of glass. Polycarbonate has a glass transition temperature of about 147 °C (297 °F), [8] so it softens gradually above this point and flows above about 155 °C (311 °F). [9]
Glass-filled polymer (or glass-filled plastic), is a mouldable composite material. It comprises short glass fibers in a matrix of a polymer material. It is used to manufacture a wide range of structural components by injection or compression moulding. [1] It is an ideal glass alternative that offers flexibility in the part, chemical resistance ...
V-Ray rendering of a kitchen using SketchUp Folded paper: SketchUp drawing rendered using V-Ray, demonstrating shading and global illumination Render created using V-Ray for Rhinoceros 3D, demonstrating the advanced effects V-Ray is capable of, such as reflection, depth of field, and the shape of the aperture (in this case, a hexagon)
Although single layer polycarbonate sheeting is more flexible than polycarbonate in twinwall configuration, it still retains significant advantages over alternative materials, including glass. A typical 6mm sheet has a density of 0.72 g/cm^2 [ 6 ] and a thermal insulation R value of 0.3 m^2°C/W, while allowing 80% of visible light pass through ...
VRay is promoted for use in the architectural visualization field used in conjunction with 3ds Max and SketchUp. It is also commonly used with Maya and Rhino. Vue is a tool for creating, animating and rendering natural 3D environments. It was most recently used to create the background jungle environments in the 2nd and 3rd Pirates of the ...
For other materials, one generally has to use importance sampling, i.e. probabilistically select a new ray according to the BRDF's distribution. For instance, a perfectly specular (mirror) material would not work with the method above, as the probability of the new ray being the correct reflected ray – which is the only ray through which any ...
Expanded polystyrene, used for building insulation, packaging, and cups, is invented by Dow Chemical. [1] 1957: The Italian firm Montecatini begins large-scale commercial production of isotactic polypropylene. 1960s: High-density polyethylene bottles are introduced; they will replace glass bottles in most applications. [11] 1965
The first commercial use of CR-39 monomer (ADC) was to help create glass-reinforced plastic fuel tanks for the B-17 bomber aircraft in World War II, reducing the weight and increasing the range of the bomber. After the war, the Armorlite Lens Company in California is credited with manufacturing the first CR-39 eyeglass lenses in 1947.
