Company : Techlead Software Engineering Limited, Pune, India
Work Experience: I developed a web page for Techlead and learned the following
2. Virtual Reality Modeling Language (VRML 2.0 and VRML 97)
These languages helped me in writing most production software at EFX and
demonstrating them over the Internet.
B: June 1995 to August 1995:
Company : Prasad Video Digital, Chennai, India
I got broad exposure in film and video making techniques on the SGI platform.
Our team of three programmers developed an artistic explosion system in
C using IRIS GL. During this time we got recognized by the Government
of India for our Research and Development efforts. The Computer Graphics
Department at Prasad Video Digital became EFX, where I am currently employed.

contain behind the scenes accounts, downloadble versions and online demos
of my present and past production software.
A. 3D PROJECTS:
A.1. N U K E :
N U K E enables MAYA Animators to use their Mouse as a
Timing tool. The animator begins by selecting the objects
he wants to retime. The keyframes of these objects are
mapped onto a standard slider in the N U K E UI. When the
animator drags this slider, N U K E notes the time at
which the animator visited the keyframes and re-spaces
them accordingly. Therefore, if the animator drags the
slider fast, the retimed animation is snappy and

A.2. F L I E S :
F L I E S is a system for animating flying insects in
Alias | Wavefronts MAYA. F L I E S is entirely written in
the Maya Embedded Language (MEL). The workflow is very
simple: the animator selects a Fly object and the Box
object in which the flies must fly. F L I E S then
generates unique random flight paths for each fly. Flies
can be lauched in layers, made to fly fast or slow,
jitter or glide smoothly. Everything happens in realtime
-- the user can change any flight parameter and see its
effect on the flies immediately.

Escher is a system for modeling visually rich designs
directly on the geometry of a 3D mesh imported from Alias
Power Animator 8.x. The user defines a pattern as a
collection of triangles and Escher replaces the triangles
of the input mesh with this pattern. An infinite variety
of patterns can be created, applied to the mesh in layers
and thus an infinite variety of designs can be produced.
Escher is written in Java and runs on IRIX and Windows
NT. Download Escher at:
A 2D pure Java demo (that runs on all platforms) and a 3D
VRML + Java demo (that runs on the PC) of Escher is also
available from the above address.
The 3D VRML + Java Demo was selected for
demonstration at the prestigious Web3D RoundUp
at VRML99, Paderborn, Germany.
XS is an interactive explosion system for Alias Power
Animator 8.x. The object that gets exploded comes from an
SDL file. Camera parameters are also read from it and
everything goes into an Open Inventor Scene Graph. This
scene graph is fed into an Examiner Viewer and the user
watches the object explode in real-time. A bomb placed
near the object causes this explosion and the user can
change its position and strength. An editable gravity
vector provides the necessary physical realism. XS
outputs the explosion as a series of SDLs for the Alias
Renderer to render. A static or an animated texture can
be applied to the 3D mesh and XS makes sure that the
exploding pieces take away the right texture chunk with
XS is written in Java and uses Kahlua [a Java wrapper for
the Open Inventor library] for the Open Inventor
interface. With Open Inventor execution environments on
IRIX and NT it runs on both these platforms.
A.5. 3D MESH I|O LIBRARY:
A set of Java classes for reading and writing 3D meshes
in OBJ or SDL format on IRIX and Windows NT. This library
was used for developing Escher and XS.
B. 2D PROJECTS:
B.1 SCRATCH REMOVAL SYSTEM:
Removes vertical and horizontal scratches from an 8-bit
SGI Image Sequence. The user begins by specifying a
window enclosing the scratch and chooses one of the
following methods to remove it:
- Linearly interpolate pixels
on either side of the scratch window to arrive at
a color value for the (scratched) pixel inside
- In the scratched area, the
blue channel is affected the most, followed by
green and red channels. Assuming the red channel
to be pure, map the relationship of red to green
and red to blue pixels on either side of the
scratch window to get a color value for the
(scratched) pixel inside the window.
- According to the
user-defined shape of the needle that may have
caused the scratch, restore the red, green and
Scratch Removal System is written
in Java and runs on IRIX and Windows NT.
B.2 SGI IMAGE PLUGIN:
Reads and Writes 8-bit SGI RGB and RGBA images in Adobe
Photoshop 4 (and above) on Windows 95 | Windows NT. It
can read image data stored verbatim or compressed using
the RLE scheme. However, it writes image data verbatim.
SGI Image Plugin was developed using C and the Adobe
Photoshop Software Development Kit.
Download the SGI Image Plugin at http://members.tripod.com/sjagannathan/sgi_plugin/
Torrent is a script-based, extensible 2D effects system.
It is actually a collection of modifiers. A modifier
takes an 8-bit SGI Image sequence as input, modifies it
in some way and writes an 8-bit SGI image sequence as
output. Thus several modifiers can be layered together
over a timeline to produce a c
