I provides GTU paper solution of Advance computer Graphics (ACG) NOvember 2013.I solve manually all the question which are given below:
Explain
axonometric projection. Derive the transformation matrix for diametric and
trimetric projection.
Write
the advantages of B-spline curve over Bezier curves. Prove that C2 continuity
is inherent in B-spline.
Explain aliasing and its effect. Also explain
anti-aliasing methods.
Explain Z-buffer algorithm for
visible surface detection.
Explain
Ray tracing algorithm.
Explain Warnock’s
area subdivision algorithm with example. Compare it with
Weiler-Atherton’salgorithm.
“BSP tree
algorithm is useful for applications in which the viewpoint changes but the
objects do not” justify the statement.
Explain the effects
of multiple knots and multiple control points for B-spline curves with diagram.
Compare image based
rendering with geometry based rendering with applications of it.
Explain
global illumination and recursive ray-tracing algorithm.
Explain gamma correction. Why it is required?
Explain
halftone approximation with its application.
Explain color model with CIE chromaticity
diagram.
Define
polyhedra. What is the necessary and sufficient condition for object to be
a polyhedron? Mention the advantages of Winged-edge
representation over other boundary representation methods.
Explain three methods for polygon mesh
representation. Also represent the object shown in Fig.1 using all three
methods.
Why half-toning technique is required? How it
can be achieved?
How do we find dominant wavelength and
excitation purity of any color using CIE diagram?
Give
applications of YIQ color model. Why we prefer YIQ model rather then RGB in
color image processing?
