Cel-FI (Cellular Fluorescence Imaging) for NCCS.This is the real-time 3D volume rendering application that was developed for the visualization of LSCEM datasets for National Cancer Center Singapore (NCCS). Previously, the scanning machine would just visualize the z depth scans and so the doctors would not be able to see the other dimensions (for e.g. the cross sectional view). To enable this, we developed a real-time 3D volume rendering application that would visualize the dataset across a network instantly. Thus, the operator would grab a scan on one end and the 3D volume will be visualized instantly on the other end. The whole visualization system was built in house without using any third party libraries. OpenCloth.I am the author of the open source cloth simulation library (OpenCloth: http://code.google.com/p/opencloth) that is specifically geared towards beginners and researchers. It implements all of the basic cloth simulation algorithms in as simple a manner as possible so that beginners know exactly what goes underneath a cloth simulation package or a physics engine. Rather than wrapping the code into a lot of classes, all of the codes are written in just a single file. The package is not just limited to cloth simulation, it also shows how to do basic soft bodies using co-rotated linear FEM.

The algorithms implemented include 2D and 3D texture slicing, shear warp, cell projection, marching cubes and marching tetrahedra, ray casting and splatting. All of these were implemented on the GPU. GPU-VDF (GPU based volume deformation).This is the current work I am working on. I am now trying to develop innovative deformation pipeline using the GPU for simultaneous visualization and deformation of volume datasets. For this work, I am using GLSL and CUDA. This work is using the features exposed in the modern OpenGL namely the transform feedback mechanism to achieve fast deformations of volumetric datasets.GPU-RAPT (GPU based ray and path tracing).Since the start of my undergraduate studies, I had been amazed by both raytracing and path tracing. I had plenty of hands on experience to build my own raytracer and path tracer on the GPU. In addition, I also had a deep look into OptiX engine as well as CUDA for ray tracing.
