Eric Haines

Eric Haines is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Eric Haines rather than just read about it. In short: Eric Haines is an American software engineer and expert in computer graphics, specifically image rendering. He was last employed with NVIDIA Corporation as a Distinguished Engineer, retiring in June 2026.

Key takeaways

Eric Haines belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Eric Haines to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Eric Haines from memory before moving on to harder problems.

Reference excerpt

Eric Haines is an American software engineer and expert in computer graphics, specifically image rendering. He was last employed with NVIDIA Corporation as a Distinguished Engineer, retiring in June 2026. He is a co-author of the book Real-Time Rendering, currently in its fourth edition. He also coauthored the book An Introduction to Ray Tracing and co-edited the book Ray Tracing Gems. Eric Haines earned an M.S. in 1986 from Cornell University. His thesis was The Light Buffer: A Ray Tracer Shadow Testing Accelerator. An image created by software based on the thesis was used on the September 1986 cover of the IEEE Computer Graphics and Applications journal. He created the Massive open online course Interactive 3D Graphics in 2013 with Udacity. As of July 2013 it had 30,000 enrolled, with 1300-1700 students active over a given week. He authored a chapter in the book An Introduction to Ray Tracing by Andrew Glassner (ed), 1989. He published a number articles in computer graphics, some of which are included in the Graphics Gems series. He also maintains the Graphics Gems code repository. Haines was on the editorial board of the Journal of Graphics Tools until 2012, at which time he helped found the Journal of Computer Graphics Techniques (JCGT). He was the Editor-in-Chief of JCGT from November 2024 through July 2025. He was the editor of the online forum of experts in ray tracing, Ray Tracing News (1988-2010) During that time, he coined the term surface acne for the spotty artifacts caused by numerical errors when a small surface area seems to be shadowing itself. He has pursued multiple personal projects including the Minecraft world mapper and exporter called Mineways.

Worked examples

Example 1 — a first encounter with Eric Haines

Start with the simplest possible case. Write down what Eric Haines claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Eric Haines before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Eric Haines ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Eric Haines

In research: Eric Haines appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Eric Haines in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Eric Haines is common in secondary-school and first-year university syllabi. It links to neighbouring topics American computer programmers, Computer graphics professionals, Cornell University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Eric Haines outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
