About

This is a tool that converts 3D objects into stylised 2D spritesheets. The user can load in a 3D model and apply a number of custom shaders to the model, and take snapshots of the model from different angles to create a spritesheet. The program currently supports the .glb and .gltf models, with texture and animation support. There is currently a pixelation and cel shader implemented. The project was made in C# with OpenTK, an OpenGL wrapper, and the source code can be viewed and downloaded from the links above.

Core Program Workflow

1. The user imports a 3D model
2. The user positions the camera around the model
3. The user applies post-processing effects to the model
4. The user creates snapshots manually or through automatic generation
5. The user exports the result into a spritesheet

Object Rendering

Supports importing .glb and .gltf models. Error handling based on Khronos glTF Validator.

Post-Processing Effects

Post-processing effects are applied to the model. Currently supports pixelation and cel shading.

Implementation Example

As proof of concept, I built a simple 2D fighting game in Unity in less than a day using the spritesheets generated from the program.
