Research & Project
Inverse Kinematics with Skinning
- Tech Stack: C++, OpenGL, Skinning
- Developed a Linear Blend Skinning (LBS) system, computing vertex transformations based on hierarchical joint influences and weighted skinning matrices.
- Engineered an Inverse Kinematics (IK) solver using Tikhonov regularization and Jacobian matrices.
Motion Capture Interpolation
- Tech Stack: C++, OpenGL, Motion Capture (ASF/AMC)
- Implemented four rotation schemes (Linear/Bezier Euler and SLERP/Bezier SLERP Quaternions)
- Reconstructed skeletal motion from reduced keyframes, eliminating gimbal lock rotational singularities
- Conducted testing by superimposing interpolated motions over ground-truth mocap data.
Unity Game Prototypes
- Tech Stack: Vulkan, OpenGL, Computer Animation, GPU Computing
- Created multiple game prototypes in Unity using C# scripting.
- Implemented core gameplay mechanics and UI elements for each prototype.
CPU Ray Tracer and Rasterizer Development
- Built a CPU ray tracing renderer and rasterizer from scratch using C++.
- Simulated GPU pipeline, including primitive assembly, clipping, rasterization, culling, and depth testing.
- Implemented perspective-corrected rasterization. Improved lighting with phong shading.
This is the result of a university course project. Code is not publicly available due to academic policy.
Multi-Filter Image Synthesis
