ostrich

ostrich is a 3D engine and custom language interprer I created for December Adventure 2023. It is inspired by moogle and pinhole, and features:

• 3D rotation and translation
• Variable focal length
• Back-face culling
• Frustum clipping
• Frustum culling
• Hidden-line removal (slow)
• Image export
• Model generation using a custom scripting language
