1 SE Mock Online Retest 2-CG * Required 1. address * 2. Name Of Student * 3. Roll No * 4. Password * Untitled Section A transformation that slants the shape of objects is called the? shear transformation translation reflection both a and b Every segment has its own attributes like Size, visibility Start position Image transformation All of these A process of changing the position of an object in a straight line path from one coordinates location to another is called? Translation Rotation Motion Both B and C 1/7

2 Which is the Computer Animation Guideline? Slow in slow out Staging Exaggeration All of the Above A scaling transformation changes the of an object? size location Shape Both A and B CMYK model are used for Computer display Printing Painting The subcategories of orthographic projection are? cavalier, cabinet, isometric cavalier, cabinet isometric, dimetric, trimetric isometric, cavalier, trimetric A composite transformation matrix can be made by determining the of matrix of the individual transformation Addition Subtraction Product 2/7

3 When visible attribute of a segment is 0. It is not included in the active segment list and display file interpreter skips this segment. is known as segment. Posted Unposted Regular None of the above The additive color models use the concept of Printing ink Light to display color Printing line Color apparent in subtractive model are the result of Amount of Reflected light Transmission of light Flow of light Color apparent in additive model are the result of Reflected light Transmission of light Flow of light Find the incorrect statement A perspective projection produces realistic views A perspective projection preserves realistic dimensions A parallel projection gives realistic representation of 3-D objects Both B and C above 3/7

4 If a polygon with co-ordinates A(2,5), B(7,10) and C(10,2) is translated 3 units in x direction and 4 units in y direction, then the resultant co-ordinates of a polygon are A (5,9), B (10,14),C (13,6) A (2,5), B (7,10),C (10,2) A (9,5), B (14,10),C (6,13) A (-1,1), B (4,6),C (7,-2) Three dimensional transformation matrix for scaling with homogeneous co-ordinates is given as Option 1 Option 2 Option 3 Option Minimum how many frames are required to create animation? /7

5 The transformation in which an object can be rotated about origin as well as any arbitrary pivot point are called Translation Scaling Rotation All of these The subtractive color model use the concept of Printing ink Light to display color Printing line The intersection of three primary RGB color produces White color Black color Magenta color Blue color Grey scale images have a maximum color depth of 8 bit 16 bit 32 bit 64 bit The initial size of segment wills be A two-dimensional array contain the details of all the segment are called Segmentation table Segment name Operation 5/7

6 Oblique projection with an angle of 45 deg to the horizontal plane is called as? Cabinet projection Isometric projection Cavalier projection Transformation matrix for reflection about Y-axix is Option 1 Option 2 Option 3 Option Apart from the basic transformation, are also used Shearing Reflection Both a & b 6/7

7 A shearing transformation changes the of an object? Size Location Shape Both A and B The point at which a set of projected parallel lines appear to coverage is called as a? convergence point vanishing point point of illusion point of delusion Which operation we can perform on segment Rename of segments Deletion of segments Closing the segment All of the above The color code 000 is for in RGB White color Black color Magenta color Blue color The transformation that produces a parallel mirror image of an object are called Reflection Shear Rotation Scaling Powered by 7/7
