Spline mode approximates a smooth animation curve, aligning the handles accordingly. Play back the ball's animation again to get a sense of how this differs from linear mode. While splined tangents work well most of the time, they can also have some potentially undesired side effects. The most common is that Maya will overshoot attribute values in order to make a smooth curve. In this example, the lowest key values represent the bouncing ball hitting the ground. The spline causes the ball to go through the ground - an effect most noticeable after the second keyframe.

Currently the tangents are set to "stepped" mode and cannot be edited conventionally. To change this we will convert them to "linear" mode, another preset tangent type. First isolate and frame the Translate Y curve. When changing tangent types, the keys of all displayed animation curves will receive tangent changes. However, if there are keys selected only those will have their tangents changed. For now we want to affect the entire curve so make sure no key is selected.

Stereoscopy, sometimes called stereoscopic imaging, is a technique used to enable a three-dimensional effect, adding an illusion of depth to a flat image. Stereopsis, commonly (if imprecisely) known as depth perception, is the visual perception of differential distances among objects in ones line of sight. There are a number of visual cues that help us to see things that way. If one object partially hides another, for example, we understand the one in front to be closer. Objects and patterns grow smaller as they recede and vertical lines converge; objects in the distance are hazier and less deeply colored, with a shift towards the blue end of the spectrum. The perspective difference between objects seen through the left and right eyes (binocular disparity) and our accommodation through focusing completes stereopsis for normal viewing. 3-D TV (and movies as well) typically work by presenting two separate images? One for the right eye and one for the left? That is incorporated through the use of specialized glasses. Another technology, known as auto stereoscopic imaging (auto 3-D), is screen-based and does not require viewers to wear special glasses. There are two classes of auto stereoscopic displays. One type tracks the viewers head position to ensure that each eye is presented with a different view. The other type of display uses multiple perspectives of each frame presented simultaneously so that, within a given range, a viewer will see separate perspectives with each eye.

New Year is something that we all look forward to. It marks the beginning of a year and the end to another year. Everybody looks forward to begin a new year with great fun and enjoyment and wish that the year ahead brings them in, all goods. Once the year is welcome, the fun does not stop. People enjoy the entire day, taking rest and welcoming the year with all high spirits and enjoyment. Everybody hopes and wishes that the year ahead would give them peace, harmony, happiness and wealth, not only for them but to mankind across the globe. On this special occasion MAAC Preet Vihar organized a Dj party for students. Students had lots of fun, dance and masti.
We wish you all a very happy new year.

In very basic terms, ISO is the level of sensitivity of your camera to available light. The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. The component within your camera that can change sensitivity is called “image sensor” or simply “sensor”. It is the most important (and most expensive) part of a camera and it is responsible for gathering light and transforming it into an image. With increased sensitivity, your camera sensor can capture images in low-light environments without having to use a flash. But higher sensitivity comes at an expense – it adds grain or “noise” to the pictures. Every camera has something called “Base ISO“, which is typically the lowest ISO number of the sensor that can produce the highest image quality, without adding noise to the picture. On most of the new Nikon cameras such as Nikon D5100, the base ISO is typically 200, while most Canon digital cameras have the base ISO of 100. So, optimally, you should always try to stick to the base ISO to get the highest image quality. However, it is not always possible to do so, especially when working in low-light conditions. Typically, ISO numbers start from 100-200 (Base ISO) and increment in value in geometric progression (power of two). So, the ISO sequence is: 100, 200, 400, 800, 1600, 3200, 6400 and etc. The important thing to understand is that each step between the numbers effectively doubles the sensitivity of the sensor. So, ISO 200 is twice more sensitive than ISO 100, while ISO 400 is twice more sensitive than ISO 200. This makes ISO 400 four times more sensitive to light than ISO 100, and ISO 1600 sixteen times more sensitive to light than ISO 100, so on and so forth. What does it mean when a sensor is sixteen times more sensitive to light? It means that it needs sixteen times less time to capture an image!

The positions of certain kinds of layers in the layer stacking order in the Timeline panel prevent groups of 3D layers from being processed together to determine intersections and shadows.
A shadow cast by a 3D layer does not affect a 2D layer or any layer that is on the other side of the 2D layer in the layer stacking order. Similarly, a 3D layer does not intersect with a 2D layer or any layer that is on the other side of the 2D layer in the layer stacking order. No such restriction exists for lights. Just like 2D layers, other types of layers also prevent 3D layers on either side from intersecting or casting shadows on one another:
· An adjustment layer
· A 3D layer with a layer style applied
· A 3D precomposition layer to which an effect, closed mask (with mask mode other than None), or track matte has been appliedA 3D precomposition layer without collapsed transformations

In the midst of today's busy lifestyle, Diwali gives an opportunity to pause and be grateful for what we have, to make special memories with family and friends, to laugh and enjoy what life offers us. Though the festival of Dipavali has undergone some changes, in due course of time, yet it has continued to be celebrated since the time immemorial. Every year, the festive season of Diwali comes back with all the excitement and merriment. Times may have undergone a sea change but customs and traditions remain the same. Diwali is one of the most colorful, sacred and loveliest festivals of the Hindus. It is celebrated every year with great joy and enthusiasm throughout the length and breadth of the country. It is a festival of lights and festivities. It comes off about twenty days after Dussehra and shows the advent of winter. It is to the Hindus what Christmas is to the Christians. It lends charms and delight to our life.
On this Special occasion Maac Preet Vihar organized Dance, Singing and best dressing competition. More than 100 students had participated in this competition and awarded as 3rd runner up, 2nd runner up and 1st prize.
Wishing you all a very happy Diwali.
