Allegorithmic's Substance 3D Designer software won the Academy Award for Technical Achievement in 2023. [13] [14] Its Substance Painter texturing tool was also used in the Oscar-winning short film Mr Hublot [15] and won an Emmy Award in 2024 in the Engineering, Science & Technology category. [16]
An in-camera effect is any visual effect in a film or video that is created solely by using techniques in and on the camera and/or its parts. The in-camera effect is defined by the fact that the effect exists on the original camera negative or video recording before it is sent to a lab or modified. Effects that modify the original negative at ...
If multiple surfaces face towards the camera, then additional use of methods such as Z-buffering or the Painter's algorithm may be necessary to ensure the correct surface is rendered. Back-face culling is typically quite a cheap test, only requiring a dot product to be calculated, and so it is often used as a step in the graphical pipeline that ...
With a known concentration of a sample, polarimeters may also be applied to determine the specific rotation when characterizing a new substance. The specific rotation [] is a physical property and defined as the optical rotation α at a path length l of 1 dm, a concentration c of 10 g/L, a temperature T (usually 20 °C) and a light wavelength ...
For a pure substance in solution, if the color and path length are fixed and the specific rotation is known, the observed rotation can be used to calculate the concentration. This usage makes a polarimeter a tool of great importance to those trading in or using sugar syrups in bulk.

Propeller of a Bombardier Q400 taken with a digital camera showing the stroboscopic effect Motion-picture cameras conventionally film at 24 frames per second. Although the wheels of a vehicle are not likely to be turning at 24 revolutions per second (as that would be extremely fast), suppose each wheel has 12 spokes and rotates at only two ...
Rotating the image plane (as by adjusting the back or rear standard on a view camera) alters perspective (e.g., the sides of a building converge), but works with a lens that has a smaller image circle. Rotation of the lens or back about a horizontal axis is commonly called tilt, and rotation about a vertical axis is commonly called swing.
