Working with Microsoft's MRCS to encode & decode custom holograms streams/mp4. My primary focus is on the native playback plugin that can be used through Unity & Unreal engine. 

Technologies involved/used - Windows media foundation (for windows) / AVFoundation (for ios/mac) / Andriod Media framework for native video decoding. OpenGL/DirectX/Metal for rendering meshes & texture data.

Technologies:
C++, Media frameworks, Andriod NDK, Video encoding/decoding, OpenGL, DirectX

Working for Matlab core graphics rendering engine, works revolves around using OpenGL, Open Scene Graph, WebGL and things related to the graphics pipeline. Implemented various algorithms such as
* FXAA
* Depth Peeling for Transparency
* Compute outer boundary for a given mesh for better vector graphics 
* Implemented performant shaders for drawing Line with width > 1.0 pixels
* Encoding/decoding floats stored in OpenGL Texture to calculate object to pick and it's corresponding depth.

Technologies:
C++, Qt, OpenGL, WebGL, Emscripten, Javascript

Member of Simulink & Stateflow Unified Editor team. 
My work mainly revolves around adding new enhancements to Canvas of Simulink & Stateflow unified Editors using 2D/3D graphics API.

Technologies:
C++, Qt, Graphics/View Framework, Meta modelling, Simulink/Stateflow, a bit of javascript :)

Project:
Allegro PCB Designer - Allegro PCB Designer quickly takes simple or complex designs from concept to production in a constraint-driven design system. It’s scalable based plus options model allows designers to cost-effectively match the technological and methodological needs of small to large companies and projects.

Technologies:
C++, Qt, Graphics/View Framework, QML, Linux

Creating various components using QGraphicsView framework of Qt.
Refactoring code to create intuitive UI using MVC paradigm
Saving and loading of state using QXml component
Using QML for creating UI components
Extensive use of Qt Graphics View framework to display graphics electronics circuits.

Project:
Cranial 2.0 – Neuro Apps - The Stryker Cranial Navigation Software offers a comprehensive solution to integrate innovative image-guided surgery into current conventional neurosurgical practices. Cranial provides support for various medical images – CT, MR, fMRI, DTI, PET.  It allows various registration modes – Fiducial & Landmark based point registration, Surface matching and Mask registration.

Technologies:
C++, Qt, OpenGL, VGL, Linux/Windows

DTI/fMRI Concept - Implement down sampling of image sets for functional overlays.
STL model importer. Created support for importing of STL model
Improvement made to User view for better support of Sagittal, Coronal, Axial images.
Implemented changes required to migrate stp coordinate system (Stryker old coordinate system) to use DICOM definition of coordinate system. stp coordinate system followed – X axis from left to right, Y from posterior to anterior, Z from feet to head, Origin is chosen to be in center of imported image slices. All this was changed to follow Dicom coordinate system i.e. – X axis from right to left, Y axis from anterior to posterior, Z axis from feet to head and Slice position is taken as provided by imaging device.

Worked on some core projects which included working on multi technologies - C++/.NET/C#/Java Applet.

Implemented design lab's rendering infrastructure for CustomInk (specifically https://www.customink.com/ndx/#/ad/gate)
