What is 3D animation ? | thespy.co.in

3D animation monitors objects by considering space coordinates and usually involves modeling,render and surface properties highlighting and camera motions.

3D animation takes the entire experience of multimedia to another level.

3D animation is the foundation upon which many multimedia CD games and adventure titles are constructed.

Creating 3D animation is considerably more complex than 2D animation and involves the following steps-

• modeling-it the process of creating 3D objects and scenes from 2D shapes. The most common methods of modeling are lofting and shape along a specific direction is lofting. Lathing involves rotation of 2D shape about an axis to create a 3D object.

 

• Surface texture-It involves imparting realistic appearences to the 3D models by applying textures over the object surface.

• Lighting-It involves placing the lights in the scene by specifying their intensities,direction and colour. The directions of shadows are also considered.

• Camera-Camera placements determine how the scene should seem.Movement of camera can be produce zooming and panning effects.

• Animation-Animating the objects involve creation of key frames and tweening to create intermediate frames. This step involves defining the object motion and how the lighting and views change during the animation.
  
  

• Rendering-This is the final step in creating 3D animation and involves giving attributes like file type,frame size,frame rate, etc.Rendering can take considerable time,depending on the complexity of the animation.

Animation के उपयोग क्या है ? | thespy.co.in

Animation के उपयोग क्या है ?

Animation का सबसे अधिक उपयोग मनोरंजन के क्षेत्र में होता है।आज के समय में Animation का सबसे अधिक उपयोग कंप्यूटर games को Realistic,रोमांचक और आकर्षक बनाने के लिए किया जाता है ।
Animation का उपयोग scientific application को दर्शाने के लिए किया जाता है जो कि practically possible नहीं होते है।

Some important points to know

Animation are largely used in the entertainment industry.

It is also at the heart of most computer games for making the graphics more realistic,interesting,exciting or engaging.

Animation can also be extremely effective in education because it provides an excellent way to explain dynamic processes which cannot be easily captured by video.

A major use of animation is to visualise simulation of scientific phenomena in industrial and scientific applications.

Animation क्या होता है ? | thespy.co.in

आमतौर पर बहुत सी ऐसी गतिविधियां या स्थितियां होती है, जिन्हें हम वीडियो में capture नहीं कर पाते है या वीडियो में capture कर पाना संभव नहीं हो पाता है, तो ऐसी गतिविधियों को दिखाने के लिए Animation एक अच्छी युक्ति साबित होती है ।

Animation एक शक्तिशाली युक्ति है जिसके द्वारा हम अपने विचारो और कल्पनाओं को दर्शा सकते है।

Animation क्या है ?

अब प्रश्न आता है कि  एनिमेशन है क्या ???

तो Animation बहुत सारी images का sequence होती है जिनमे हर image पिछली image से अलग होती है और जब इन images को एक के बाद एक क्रम में लगाकर तेजी से चलाते है तो एक भ्रम प्रतीत होता है जिससे  देखने में ऐसा लगता है कि ये images चल रही हो

Some important points to know

Animation is a powerful tool used to coonvey a range of ideas in multimedia presentations.

Animation provides a convenient way to explain subject matters when capturing video is not practicable.

 Animation is an object actually moving across or into or out of the screen.

Animation are created from a sequence of still images. Each image is slightly different from the privious one.

Then these images are displayed quickly one after another so that the eye is fooled into perceiving continuous motion due to persistence of vision.

Animation के principle (सिद्धांत) क्या हैं ? | thespy.co.in

Animation के principle(सिद्धांत):-

Squash and stretch-

A bouncing ball is a classical example of Squash and stretch and stretch. An animation of bouncing ball that does not change shape as it moves provides a lifeless, mechanical impression. To be more realistic the ball shape should be flattened as it strikes the ground and return to the original shape when it rebounds back into the air. The amount of flattening and the height from which the ball is falling are proportional to each other.

Anticipation-

the motion looks akward and confusing if the audience is not prepared for a sudden a sudden motion. In life, we usually prepare to act before we actually act and the animation should and the animation should make this clear.

Staging-

staging refers to arrange things each frame so that the action is clear and easy to see. If there are many things happening simultaneously at different places, the audience would not know where to see.At give a moment a scene has only a has only a scene has only a has scene has only a has moment a scene has only a has only a scene has only a has scene has only a has only a few main characters.Staging emphasis on those characters and integrate them with the background.

Follow-through and overlapping Action-

follow through and overlapping have to do with clarity. For instance, when you throw a frisbee your arm continuous it's long arc after the frishbee Has left your hand. Including follow through make an action Apparent an action Apparent. Anticipation and follow through combine in overlapping action. It is necessary to bring one action to a complete stop before beginning the next. Overlap contributes to the continuity of a scene.

Slow-in and Slow-out-

slow-in and slow-out means that there are more in between frames immediately before and after each Stop, with fewer frames for faster action action in between two stops. Slow in and slow out contributes to realismbecause in the real world that how the object move.

Arcs-

living thing I rarely move in straight lines. Our joints are hinges,and moving them describes an Arc. The overall movement of characters in an animation should follow an arc as well. This is what your life like and more interesting visually.

Secondary action-

each part of a character might not move at the same speed. For example, a Robe trail behind a running character including secondary action contributes to realism.

Timing-

The speed of an action is an important way to display a character's intent. Timing is also an important way to show weight. Holding an important moment of scene is just as important as getting proper speed. A hold give the audience time to identify what is going on for example a character who walks off a cliff but does not fall until he or she looks down.

Exaggeration-

Exaggerating an action can make it seems real. This is especially true in animation. Exaggerating the important elements makes them stand out and brings them closer to the viewer.

Appeal- 

All the characters in an animation should have appeal. Appeal is visual as well as psychological. Characters that are visually intriguing are more likely to hold an audience attention then characters whose whose whose appearance is mundan or predictable.
