1. Interest in algorithm design and coding for Competitive Programming.

This involves solving problem sets from the annual . A list of the problem sets can be found at http://acm.uva.es/problemset. See the following web address for my set of solutions to some of the problems: http://www.rendezvouswithdestiny.net/Online_Judge/

2. Demo coding and the Demo Scene.

Demos are executable which produce, in, engaging computer graphics and music. Programming, Art, and music Composition skills are stressed. Demos are similar in some ways (but are not equivalent) to music videos or short films. See http://www.scheib.net/play/demos/what/hugi/index.html for a short introduction of the demo scene. See http://www.rendezvouswithdestiny.net/demoscene.htm for some of my works in demo coding.

My passion for Computer Graphics began many years back in my college days when I happened to chance upon the PC demo 2nd Reality by Future Crew, which was listed by Slashdot.org as Top 10 Hacks of all time. Since then I spent quite a large part of my time (about 8 yrs beginning from ’97) on learning about realtime graphics programming and coding various effects that were popularly used in various demos back then. Since graphics accelerators were non-existent during that time, everything has to be from the ground up. Major work includes a 3d software engine coded from the ground up without the use of hardware acceleration and API libraries, since these are practically non-existent back then in 1997. The 3D engine features software guoraud shading with software Z-buffering. Other misc. routines are also implemented such as bresemham’s line routines in C with hand optimized inline assembly. I have also coded a bunch of other old school demo effects such as fire, water ripples, lens effect, particle morph and motion blur using palette rotation.

Hence I have a good familiarity with the graphics pipeline and a good grasp of fundamental issues and optimization aspects of coding realtime graphics. Most codes were developed in C with inline Assembly and I am able to appreciate how handcoded assembly instructions can outperform compiler generated codes. A portfolio of various 3d and 2d effects is available on request. Thru my university days and in graduate school I continue to take an interest in graphics and later on computational geometry when I was in graduate school.

3. Language Proficiency and API Knowledge

I am fluent in C, C++ (ard 7 yrs coding exp since Junior College), Assembly and also C with inline Assembly, since those are the predominantly used languages in demo coding. Other languages known include Java and Perl as well as application development using MFC.

Practical Experience with Opengl, Nvidia Cg Shaders, CGAL(Computational Geometry Algorithms Library) in both Windows and Linux Platform.

Experience also with multithreaded application programming used for multithreaded data prefetch in terrain rendering system used in conference paper.

4. Collaboration work with Dept of Architecture NUS.

My Masters thesis (manuscript for this work is pending publication) was on a collaboration project with the Dept. of Architecture in NUS on the topic of automatic generation of building forms. This research features the use of Nvidia fragment and vertex shaders for intelligent architectural form computation as well as an interactive user interface for form manipulation. It also presents novel data structures and algorithms for form generation. Through this collaboration, it has widened my perspective on the use of computer graphics techniques in cross discipline projects.

5. Skill set summary.

C, C++, Boost C++ Library, Assembly (and also C with inline Assembly), Java, Perl,

Opengl, Glut(GL Utility Toolkit), Nvidia Cg Shaders, CGAL (Computational Geometry Algorithms Library) in both Windows and Linux Platform, Linux development environment (gcc, emacs, vim), MFC programming, Bash Shell scripting, 3ds MaxScript, Win32 threading.

Familiar with C++ coding standards outlined in classics books ( Effective/ More Effective C++ by Scott Myers) as well as software architecture principles from the book on Design Patterns . These are advocated Autodesk-wide and weekly discussions/presentations are held on topics covered in these texts. Also trained in ObjectARX development which is used for developing sub-apps running on top of the AutoCAD application.

Software Engineer with Autodesk Vault Team

64-Bit Porting of Autodesk Vault codebase.

Responsible for the porting effort of the Vault codebase to the 64-bit Windows OS (x64) on the Amd64 hardware platform. The porting effort involves major planning and collaboration with Autodesk-wide dev-teams due to the dependencies between each of the Autodesk suite of products and Vault, as well as Vault’s dependency on other Third-party utils.

Major issues include:Handling the mixed codebase of C++, managed C++ and C# code and the implications and issues when moving to the 64-bit platform. Resolving issues concerning the use of P/Invoke in C# and its implications on 64-bit migration.Use of polymorphic datatypes in Win64 API in porting effort.Maintaining one single codestream that cross-compiles to Win32 and Win64 target platforms.Understanding, identifying, resolving the following throughout the entire codebase, Size of primitive data types between 32-bit and 64-bit platformPointer truncation and sign extension issues on various datatypesIndentifying and fixing C++ struct packing issuesConverting existing inline Assembly language routines to C++ equivalent since Win64 no longer support inline asm.Dll dependencies – 64-bit processes cannot load 32-bit dlls and vice versaEnforcing typesafe C# code.

Software Specifications Drafting Experience

Worked on spec for part of AutoCAD’s UI revamp for upcoming release (AutoCAD 2009) for Windows Vista Developed code for the above as part of new Vista UI initiatives for AutoCAD functionality related to Vault.

Development of various new features in Vault Addin for Autocad.

Vault addin for AutoCAD is an ObjectARX application which integrates with AutoCAD to allow the check-in of AutoCAD DWG files from the AutoCAD application. This similar to a CVS for CAD files and the following are the features worked on to date,

Integration issues with Autocad application. DWF publishing when checking in DWG files with Vault Addin Attach/Open from Vault files in AutoCAD.

Development/maintained various features in product Autodesk Autoloader This is a bulk upload utility to upload entire customer Dwg data to Vault servers.

Header dependency tracing for AutoCAD

This project stems from the need to identify the set confidential AutoCAD header files from the set of ObjectARX header files (which are released to the public) that is included for use by the Vault Addin for AutoCAD.

Developed custom solution to the problem when off-the-shelf tools are unavailable. Investigated to use of special g++ commandline options to that will be able to solve the problem together with some ‘hacks’ involving the pre-preprocessing of vault source files.Installed linux environment on home PC so as to use gcc for tracing the header dependency tree. Investigated sed, perl and bash scripting to preprocess vault source files before they can be used with g++. Preprocessing issues solved by the scripts include, Stripping all header files clean of WIN32 preprocessor directives since they will pose problems on the g++ platform. All files processed so that #pragma once is insert in every header and all .cpp and .h files only contains #include statements.Lowercasing all #include statements, batch converting all directory names and file names to lowercase. This is important since unix filenames are case sensitive.Bash scripting for invoking g++ with –MM option on each .cpp file to generate the list of files in its header dependency tree.Post processing each generated list above to remove duplicates.Subsequently created similar scripts for processing on windows platform used in conjuction with visual c++ compiler’s generate preprocessor output file output.

All the efforts contributed towards to ability to remove all dependency of vault code on private and confidential acad headers. This allows greater productivity by leveraging on the outsourced development efforts that will no longer need to access private acad headers.

Visual Studio Addin development

Developed in my free time a dependency management tool addin using the Visual Studio Extensibility API that presents visually the various dependencies such as header, include files, library files, include paths, library paths and in which projects they were used. This is helpful due to the large number of projects (50 C++/ C#) in the solution module that we are working on. See below for screen shot. DevExpress widget API knowledge is used in the creation of this addin.

B.Eng Dissertation (HYP) : An Adaptive Pre-fetch Algorithm for Out-of-Core Visual

Simulation

[Supervisors: Dr Tan Tiow Seng, SoC, NUS / Dr Ong Sim Heng, ECE, NUS]

Developed formalism for the analysis of the prefetch problem in out-of-core visual

simulation. Implemented an adaptive prefetch algorithm for large scale walkthroughs that dynamically adapts prefetch requests to the density of data in the vicinity of the viewer while ensuring low page fault rates. The performance of the prefetch algorithm is supported by theoretical results derived from the formalism proposed. Results from this work was subsequently presented in a paper in the proceedings of the Computer Graphics International 2005.
