Engineering Project

Vulkan Graphics Framework 

Jun, 2023 - Present

• Created Clustered Shading using Compute Shader, which helps optimize a scene with a large number of lights

• Utilized Vulkan synchronization allows GPU to render and present separately to reduce wait time on the host

• Created a GPU particle system that computes millions of particles synchronously with the graphics pass

• Implemented Parallax Occlusion using pyramidal displacement to improve depth illusion on the flat surface

• Added real-time raytracing mode using the Monte Carlo method to accumulate light data along the path

• Improved the raytracing result by Denoising with De Boor’s algorithm to mitigate artifacts from randomness

• Added Deferred Shading Pipeline to support a tremendous amount local lights with maximum efficiency
  
  

Animation Framework

    Aug 2023 - Present

• Created a keyframe-based Animation framework using Vulkan to display the 3D models with debugging joints

• Utilizing VQS (Vector, Quaternion, Scale) to reduce the calculation of the transformation concatenating from matrix multiplication

• Added the motion control that supports ease-in/out along the Catmull-Rom curve for realistic animation

• Implemented Inverse-kinematic (IK) using a FABRIK approach and Slerp to create natural movement

Night Owl Engine -- Custom 3D/2D Game Engine using C++

Aug, 2022 - Present

• Implemented the hybrid particle system that offloads the position calculation of each particle to the GPU

• Created Material Serializer, which reads the uniform layout from GLSL shaders and creates Material Object

• Added Debug Rendering System that uses geometry shader to show polygon mode with surface normal vectors, making debugging easier.

Vana Engine -- Custom 2D Game Engine

Aug, 2022 - Nov, 2022

• Added Scene Graph in the rendering system which helps organize the GameObjects and their relationship.

• Created a GameObject System using Component Pattern which helps decoupling and organizing.

• Added GameObject Factory to deserialize the scene from JSON files to improve the scene creation process.

• Integrate ImGui and implement easy to use custom DebugUIWindow to help users in debugging. 

• Implemented 2D OBB Collision Detection using separating axis theorem and broadcast to Event System.

• Optimized the Collision Detection by separating colliders into layers which remove unnecessary computation.

Professional Experience

Freelance Unity Game Developer (Simu Cafe Match 3 Game)

Library Group, Phuket Thailand

May, 2022 - July, 2022

• Implemented a system to handle interaction between states in match 3 game using gamestate pattern

• Created algorithm to check dead-end for level generator using decision tree.

• Optimized core matching mechanic to support any match pattern with less intensive calculation.

• Created Auto Tile Generator using rule-based  to help designers create any tile map from spreadsheet.

• Integrated the network script to communicate with the server using the event system.

Contract Unity Shader Engineer (Reliquary - Nintendo Switch)

Jade Ember Studio, Boulder, CO  

Oct, 2021 - April, 2022

• Created 5 PBR triplanar shaders using Amplify to map texture on irregular terrain, with highly customizable.

• Improved each shader using Amplify to support vertex painting which blended textures with height maps.

• Implemented custom normal map calculation based on world coordinates to support triplanar shader.

• Optimized shaders to support Nintendo Switch by reducing the calculation while achieving the same visual.

• Implemented custom normal map calculation based on world coordinates to support triplanar shader.

Godot Game Developer (Project ICHR - IOS)

Cubic Creative Co.,Ltd., Bangkok Thailand

Mar, 2018 - Oct, 2021

• Led the developing team implementing 2D Game using Godot Game Engine.

• Created custom 2D lighting map for character and its shader to achieve comic like lighting.

• Created Flashing fill shader to help emphasize the player feedback using GLSL.

• Created procedural 2D lightning effect for lightning weapon type.

• Designed the bullet pattern generation system to help designers to test the enemy behavior design.
