CG SET case studies
CG SET · Put your knowledge to work in context.
The Computer Graphics Society of Educators and Trainers (CG SET) Certification Examination is a professional credential for people who teach, train, or assess computer graphics and for practitioners who want to demonstrate breadth across the field. It is aimed at instructors in degree programs, bootcamps, and corporate training, as well as technical artists and engineers moving into education. The CG SET case studies are 5 cases and about 4,594 words.
1Wing Mirrors Vibrating 31 km From the Origin
A studio is porting its racing engine to an 80 km × 80 km open world. World-space positions are stored and uploaded as 32-bit floats; the CPU camera transform is computed in double precision, but the view matrix is cast to float before upload.

A forward renderer uses a 24-bit fixed-point depth buffer with near = 0.1 m and far = 20,000 m. Road decals (lane markings, authored 2 mm above the asphalt) flicker between 1.5 km and 4 km; cockpit geometry at 0.3–1 m is rock solid; distant terrain is clean because it is drawn in a separate far pass with near = 50 m.

An outdoor scene uses a 4096² foliage atlas: 64 leaf-card clusters, each in a 512² tile with an 8-pixel gutter filled by RGB dilation. Textures are stored as sRGB with straight alpha, and the engine generates a full 13-level mip chain with a box filter that averages R, G, B, and A independently, on the sRGB-encoded values.

A 1080p title targets 60 Hz on a mid-range desktop GPU. A 300-frame capture reports: frame time 21.4 ms (P99 27 ms), GPU busy 17.2 ms, CPU main thread 19.8 ms, render thread 14.1 ms.

An instructor teaching a 38-student computer graphics course assigns a BVH-accelerated ray tracer worth 15% of the grade. The syllabus says only "discuss ideas freely, but write your own code" without defining shared code, tutorials, or AI assistance.
