Position:

Responsibilities: |
Developing the Hair&Fur plug-in (a part of 3ds Max 7.5 and
better), developing the LipService (was LBrush) sculpting and
animation plug-in for 3ds Max and Maya. |
Hair&Fur 3ds Max's
plug-in.
I am
maintaining and hooking new features in Hair&Fur bridge for 3ds Max 9,
2008, 2009, 2010. The most significant of them were: hair styling inside the 3ds
Max's viewports (hair was styled in GUI window in prior versions),
connection to new mr shaders, assigning shaders to hair primitives,
volumetric reflections etc..
Developed V-Ray Hair
geometry primitive shaders.
LipService (was
LBrush) plug-in for 3ds Max.
LipService w/LBrush was designed to be a fast and effective tool for
creating facial animation and target sculpts. 15 Sculpting Tools, Loop
and Catmul-Clark sub-divisions, ability to paint vertex color and use it
as stencils, advanced morphing allows to create animation just in few
clicks, multi-track animation, baking to texture normals, displacement,
vertex color. I have developed this stuff from a scratch
LipService (was
LBrush) plug-in for 3ds Maya.
Maya version
LipService will have the same set of features as 3ds Max's one. v 3.0 is
under developing now.
GLSL Hair Shaders.
I developed a prototype of hair shaders to
work with Shave Engine. Hair shape is generated by vertex shader.

Dec 2004 - Jan 2006 |
|
I was free
for a couple of months so did some stuff for myself. |
|
|
The contract with my
employer ended so I had a bit of time to make
some own small project - the
Deformation Texmap (DTX_Deformation) that blends tree Colors/Sub-Texmaps
due to Model's deformation. I was going to make a series of DTX (Dynamic
Textures) but got another job. Hope I'll give the 'second breath' to
this stuff at some moment.

Position:
|
Software
Engineer |
|
Responsibilities: |
Developing the Particle Flow Tools Box3 ( 'Data View' and 'Data
Sub-Operators' ),I was involved in developing Particle Flow Tools
Box2 (Speed Spine Operator and PHammer Modifier ), developing
some utility stuff. |
|
|
Particle
Flow Tools Box3
I
implemented the schematic editor ('Data View') for 'Data Operator'
which is a part Particle Flow Tools Box3. All items can be dragged,
wired, resized, flipped, renamed, grouped etc. Sub-Operators can be also
stacked into blocks. Particle Flow Studio has a similar editor (Particle
View), it was implemented using ActiveX, while 'Data View' uses MFC
stuff.
I also implemented data
processing of many Sub-Operators here like 'Geometry' (particles and
geometry interaction), 'Particles' (particles and particles interaction)
and others. More details about PF Tools Box3 you can find on Orbaz Technologies site:
www.orbaz.com
Particle
Flow Tools Box2
I
implemented the 'Speed Spline' Operator which is a part of Particle Flow
Tools Box2. It creates force-field around selected shapes. Below there
are
screenshots of force-field gizmo. As a part of Box2 developing I
was involved into creating the
PHammer , a
mesh fracture Modifier.
But only initial coding was performed at that moment.

Developing motion capture utility plug-in. |

I developed
a pretty simple plug-in from capturing the motion from 'P5
Glove' device

It was really the
first own rendering project (RaySys). After more than a year of
hard work I had a good ray-tracer which has the speed
approximately as VRay and Mental have. And I started to
implement the Area Lights. But indeed it was a too big project for
me to compete alone with other products. So it is frozen now.
But I got really good experience working on it :). |

Reflection and Refractions were implemented.
The
work over area lights was only started and I have frozen this project.
