Physically-Based Path Tracer for a Product Visualization Studio
Overview
What this challenge is about.
Physically-Based Path Tracer for a Product Visualization Studio. Expert-level challenge in code. Writing production code that solves real engineering problem...
The Brief
What you'll do, and what you'll demonstrate.
Build a physically-based CPU path tracer that reproduces a third-party render farm's quality on 4 industrial-product scenes within an art-director-signed-off visible-difference threshold.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Implement a path tracer respecting physically-based rendering math
- Build and traverse a BVH for ray-scene acceleration
- Apply multiple importance sampling correctly
- Validate render quality against reference using objective metrics + human review
