I have been working as a Python scientific software developer for the past 3 years. My open source contribution to this field has been as a Mayavi Developer. Mayavi is an open source package built on top of VTK for 3D scientific visualization. I upgraded Mayavi to be compatible with the new VTK 6.x pipeline architecture while ensuring backward compatibility upto VTK 5.10.

In the year 2012, I launched a 3D cricket strategy game titled Dial Cricket. I had prototyped that game in Common Lisp, while the actual app shipped to the app store, was developed using Objective-C with GLKit. 

As of now, I am working on a 3D cricket simulation game. This is developed entirely using SceneKit, SpriteKit.

I have also just started a new open source project, which converts files imported with Assimp into SceneKit. https://github.com/dmsurti/AssimpKit. As of now, it imports 3D mesh with materials (colors and textures), lights and cameras. I am working on skeletal animation import. I am working on 2 approaches: one using SceneKit native skinner and the other by doing skeletal animation on the CPU. See the git branches: add-skeleton and add-custom-skinnier.

I have worked at the lower level using raw OpenGL with C-bindings as well as using GLKit and even PyQt to write shaders. One good example that comes to mind is doing ray tracing on the GPU.

Another shader that I am working on is to show a comet like tail for the cricket ball in the cricket simulation game.

I also developed a scene graph from scratch in Common Lisp where I have written both vertex shaders (covering all coordinate systems local, world to device) and fragment shaders (that implement phong and blinn lighting models).

I developed a search tool that would dynamically generate SQL Queries for an Oracle database at runtime based on the input search parameters. This was for the marketing team at one of the top 6 Hollywood movie studio. (SBCL, Lisplets) (http://lisplets.sourceforge.net), this was before Rich Hickey gave us Clojure!

I prototyped an itinerary builder in Common Lisp (SBCL) for Disney theme parks using the TSP algorithm.

I have prototyped an entire scene graph (drawing a lot of design inspiration from SceneKit) with OpenGL 4.x, that supports lights, cameras, colors, textures. https://gitlab.com/cl-3d-graphics/cl-scene. This also has a reference Lispworks 3d implementation for actual rendering, but as I am using a closed source OpenGL binding from LW, I have not been able to open source it.

And I have contributed for minor tests, documentation and integrating Travis for cl-nlp. https://github.com/vseloved/cl-nlp/commits?author=dmsurti
