For 3D animation Bézier curves are often used to define 3D paths as well as 2D curves for keyframe interpolation.

For example, subjects who stare continuously at a Necker Cube usually report that they experience it " flipping " between two 3D configurations, even though the stimulus itself remains the same.

For 3D animations, objects ( models ) are built on the computer monitor ( modeled ) and 3D figures are rigged with a virtual skeleton.

For 3D animations, all frames must be rendered after modeling is complete.

For 3D deconvolution, one typically provides a series of images derived from different focal planes ( called a Z-stack ) plus the knowledge of the PSF, which can be derived either experimentally or theoretically from knowing all contributing parameters of the microscope.

For sufficiently capable combinations of hardware and operating systems, X. Org plans to access the video hardware only via the Direct Rendering Infrastructure ( DRI ), using the 3D hardware.

For hardware accelerated 3D and 2D acceleration on Linux, Mac OS X and DOS, AllegroGL and OpenLayer are available.

For example, if a certain protein is implicated in a disease, its 3D structure provides the information to design drugs to interfere with the action of the protein.

For instance, the missiles in Total Annihilation travel in real-time in simulated 3D space, and they can miss their target by passing over or under it.

* For 3D Studio Max: PaxRendus by Archonus ( discontinued )

For example, one can zoom in and out of GUI-buttons in the same way one zooms in and out in the 3D viewport.

For example Nissan ( 2008 LA Auto Show ), Best Buy ( 2009 ), and others used webcam based AR to connect 3D models with printed materials.

For example, if software programmed using Direct3D requires pixel shaders and the video card on the user's computer does not support that feature, Direct3D will not emulate it, although it will compute and render the polygons and textures of the 3D models, albeit at a usually degraded quality and performance compared to the hardware equivalent.

For example, video cards with 3D accelerators ( most, ) have two voltage and clock rate settings, one for 2D and one for 3D, but were designed to operate with three voltage stages, the third being somewhere between the aforementioned two, serving as a fallback when the card overheats or as a middle-stage when going from 2D to 3D operation mode.

For example, a teapot is listed as a primitive in 3D Studio Max.

For the price of a second Voodoo2 board, users could easily improve 3D throughput.

For games published by Apogee Software Ltd., see 3D Realms.

For example if you are being told about a chair it is clear to you that the chair is in space, that it is 3D.

For 3D displacement fields it is expressed as derivatives of displacement functions in terms of a second order tensor ( with 6 independent elements ).

For the 1998 title Grim Fandango, LucasArts retired the SCUMM engine in favor of a new 3D engine.

For example, 3D logos, chrome versions and so forth.

For example, one study on volunteerism found that feeling overwhelmed by others ' demands had an even stronger negative effect on mental health than helping had a positive one ( although positive effects were still significant ).

For more information on the harmful effects of abiotic stress, see the sections below on plants and animals.

For example, anticholinergics are often used to alleviate the motor side effects of antipsychotics.

For almost the next 1, 000 years, these states, their relations with each other, and their effects on the peoples who lived in stateless societies along their peripheries dominated Chad's political history.

For example, the effects on the character of the agent or any other people involved in an action may be regarded as a relevant consequence.

For lower frequencies of EMR up to those of visible light ( i. e., radio, microwave, infrared ), the damage done to cells and also to many ordinary materials under such conditions is determined mainly by heating effects, and thus by the radiation power.

For low-frequency radiation ( radio waves to visible light ) the best-understood effects are those due to radiation power alone, acting through the effect of simple heating when the radiation is absorbed by the cell.

For these thermal effects, the frequency of the radiation is important only as it affects radiation penetration into the organism ( for example microwaves penetrate better than infrared ).

For a reduction in narcotic effects trimix or heliox, gases which also contain helium, are generally used by divers.

For instance, an individual or group may choose to focus on the benefits of high levels of production and consumption, rather than on its harmful effects on the environment.

For this reason, the term is often applied to films and plays of a stylised nature with heightened acting, melodrama and theatrical effects such as Sweeney Todd, Sleepy Hollow, Quills, and the Hammer Horror films that went before them.

For British Catholics its effects were disastrous both socially and politically: Catholics were denied the right to vote and sit in the Westminster Parliament for over a century ; they were also denied commissions in the army, and the monarch was forbidden to be Catholic or to marry a Catholic, a prohibition still in force.

For this reason, however, ' narcotic ' has come to mean any illegally used drug, but it is useful as a shorthand for referring to a controlled drug in a context where its legal status is more important than its physiological effects.

For example, in 1994, Irving Kirsch characterized hypnosis as a " nondeceptive placebo ," i. e., a method that openly makes use of suggestion and employs methods to amplify its effects.

For this reason, most implantation is carried out a few degrees off-axis, where tiny alignment errors will have more predictable effects.

For example, the tobacco industry has used the term " junk science " to describe research demonstrating the harmful effects of smoking and second-hand smoke, through the vehicle of various " astroturf groups ".

For high speed aircraft moving at transonic speeds the effects of incompressibility can't be neglected.

There are several hypotheses about how tolerance develops, including opioid receptor phosphorylation ( which would change the receptor conformation ), functional decoupling of receptors from G-proteins ( leading to receptor desensitization ), μ-opioid receptor internalization and / or receptor down-regulation ( reducing the number of available receptors for morphine to act on ), and upregulation of the cAMP pathway ( a counterregulatory mechanism to opioid effects ) ( For a review of these processes, see Koch and Hollt.

For other neurotransmitters, such as GABA, the most important receptors all have inhibitory effects ( although there is evidence that GABA is excitatory during early brain development ).

For example, a good displays local network effects when rather than being influenced by an increase in the size of a product's user base in general, each consumer is influenced directly by the decisions of only a typically small subset of other consumers, for instance those he or she is " connected " to via an underlying social or business network.

For example, concurrent use of NSAIDs and quinolones may increase the risk of quinolones ' adverse central nervous system effects, including seizure.

For example, ketoprofen's effects have been studied in horses more than in ruminants but, due to controversy over its use in racehorses, veterinarians who treat livestock in the United States more commonly prescribe flunixin meglumine, which, while labeled for use in such animals, is not indicated for post-operative pain.

For very small, dense features (< 125 or so nm ), lower resist thicknesses (< 0. 5 micrometres ) are needed to overcome collapse effects at high aspect ratios ; typical aspect ratios are < 4: 1.

For example, since we often see effects as " like " their causes, one way to invent an argument ( about a future effect ) is by discussing the cause ( which it will be " like ").

For example, a combination of depressant drugs that affect the central nervous system ( CNS ), such as alcohol and Valium, can cause a greater reaction than simply the sum of the individual effects of each drug if they were used separately.
