- Dynamic shadows and reflections
- HDR rendering workflows

- Create advanced GLSL shaders for materials such as metals, glass, fabrics, transparency, and procedural surfaces

- Implement post-processing effects including Bloom, Ambient Occlusion, Depth of Field, Tone Mapping, and Color Grading

- Build interactive 3D configurators and visualization tools

Graphics Performance Engineering:

- Deliver smooth 60 FPS rendering across desktop and mobile devices
- Optimize GPU memory usage, shader execution, draw calls, and rendering performance
- Implement:
- Level of Detail (LOD) systems
- Frustum and Occlusion Culling
- Instancing and Geometry Batching
- Resource Streaming and Asset Caching





- Optimize loading performance for large and complex 3D assets

- Work with compression technologies including Draco, meshoptimizer, and KTX2/Basis

Graphics Architecture & Systems:

- Design and build scalable rendering architectures and scene management systems
- Develop reusable shader libraries, material systems, and rendering modules
- Build graphics APIs and rendering abstractions for frontend integration
- Create scalable systems capable of handling large 3D asset catalogs

3D Asset Pipeline:

- Work with formats including:
- glTF 2.0
- USDZ
- FBX
- OBJ
- Collada

- Implement asset optimization techniques including:
- UV workflows

- Texture atlasing

- Mesh decimation

- Tangent generation

- Progressive loading and streaming

- Build debugging and visualization tools for asset inspection and performance analysis

Interactive 3D & XR Experiences:

- Develop advanced camera controls, interaction systems, and mobile gestures
- Build:
- 360° product viewers
- Interactive hotspots and annotations
- Measurement tools and view presets

- Implement browser-based AR/VR experiences using WebXR

- Build cross-platform AR experiences for iOS and Android

- Integrate technologies such as AR Quick Look, AR.js, and modern WebXR frameworks
