The document discusses Daroko blog, which provides tutorials and information on various IT topics such as computer graphics, networking, programming, and more. It encourages readers to not just learn the concepts but to apply them in real business contexts. The blog can be found by searching "Daroko blog" or visiting its website at professionalbloggertricks.com. The document then discusses computer graphics and describes some of its major subfields: geometry, which studies the representation of 3D objects; animation, which looks at representing and manipulating motion; and rendering, which converts models into images through light transport simulation or other styles.

3. Computer graphics
Computer graphics is a sub-field of computer science
that is concerned with digitally synthesizing and
manipulating visual content..
A broad classification of major subfields in computer
graphics might be:
Geometry: studies ways to represent and process
surfaces
Animation: studies with ways to represent and
manipulate motion
Rendering: studies algorithms to reproduce light
transport
Imaging: studies image acquisition or image editing

4. • Computer graphics broadly studies the
manipulation of visual and geometric
information using computational techniques.
Computer graphics as an academic discipline
focuses on the mathematical and
computational foundations of image
generation and processing rather than purely
aesthetic issues.

5. 1. Geometry
The subfield of geometry studies the
representation of three-dimensional objects
in a discrete digital setting. Because the
appearance of an object depends largely on
the exterior of the object, boundary
representations are most common in
computer graphics.

6. 2. Animation
• The subfield of animation studies descriptions
for surfaces (and other phenomena) that
move or deform over time.

7. 3. Rendering
• Rendering converts a model into an image either by
simulating light transport to get physically-based
photorealistic images, or by applying some kind of
style as in non-photorealistic rendering.
• The two basic operations in realistic rendering are
transport (how much light gets from one place to
another) and scattering (how surfaces interact with
light).
