Thank you for your participation!
We are looking to hire a part-time developer to maintain and enhance an existing project. The project is built as a jQuery widget that uses jQuery UI and incorporates Three.js for rendering an overlay image on top of a background image (typically a product image such as a bottle, T-shirt, baseball cap, USB memory, etc.). The overlay image is usually a logotype.

Various built-in effects are used to make the logotype rendering more realistic. These effects are achieved using GLSL shader code.
Effect examples:
- Emboss
- Cylinder (wraps overlay around a cylinder)
- Lightning map
- Displacement map
- Texture blending
- Drop shadow
- Masking (masking out portion of the image)
Example (cap with emboss and texture)

What We Need Help With
The ideal candidate will initially make small, manageable changes to familiarize themselves with the codebase. In the future, the role may involve upgrading Three.js to its latest version, enhancing GLSL shader code, and optimizing the overall project.
Note:
The code is written in Coffeescript, which is largely obsolete. However, it has already been partially converted to JavaScript, and further conversion to JavaScript/TypeScript can be automated with a tool like decaffeinate.
If this opportunity sounds interesting, please contact me for more information.

I notice you've shared a job posting that appears to be closed. While this isn't directly a question about Three.js, I can provide some relevant information about the Three.js features that would be involved in such a project.
The job description mentions several effects implemented with GLSL shaders in Three.js, including:
- Emboss effects - These can be created using custom shaders that manipulate normal maps
- Cylinder mapping - Three.js provides utilities for mapping textures onto cylindrical surfaces
- Lightning maps - Likely referring to light maps for realistic lighting effects
- Displacement maps - Three.js supports displacement mapping for adding surface detail
- Texture blending - Combining multiple textures for realistic material effects
- Drop shadows - Can be implemented using shadow mapping techniques
- Masking - Using alpha channels or stencil buffers to mask portions of rendered content
If you're interested in learning more about implementing these effects, Three.js provides several addons and utilities that might be helpful:
- For shader development: WebGLProgram documentation
- For texture manipulation: Various loaders like TextureLoader
- For geometry manipulation: BufferGeometryUtils
- For post-processing effects: EffectComposer
Would you like more specific information about any of these Three.js features or techniques?
