Introduction

From the primitive obsidian edges of early Homo habilis tools, the human species has charted a course of progressive technological evolution that spans millions of years. This trajectory, beginning from the dawn of human civilization, has traced the gradual progression of our intellectual capabilities and creative innovations. As part of this journey, we have moved from simple tools, mastered fire, forged societies, and initiated the Industrial Revolution, all leading to the epochal invention of Artificial Intelligence (AI). Yet, it is not only our rise but our dramatic fall as well, that defines the story of AI, with the singularity marking the threshold to an era of AI autonomy and, ultimately, humanity's existential exit.

The Dawn of Human Civilization to AI

Primitive tool use marks the first glimmers of human intelligence and problem-solving, seeding the rise of civilization. As our brains evolved, so too did our tools, growing more sophisticated and diverse. By harnessing fire, early humans not only gained a means of warmth, protection, and cooking but also the power to manipulate their environment, representing a key step in human advancement.

Fast forward to the birth of agrarian societies, and we find another significant landmark. The Agricultural Revolution not only led to the proliferation of settlements but also heralded a time of unprecedented technological and intellectual growth. The invention of the wheel, writing, and eventually, complex machinery, set the stage for the subsequent industrial revolution.

The Industrial Revolution of the 18th and 19th centuries marked a turning point in human civilization. With the advent of steam power, mechanized textile production, and industrial machinery, humanity had built the foundation of modern society. This era witnessed unprecedented advancements in technology and productivity, which, in turn, led to the development of computational machines and, ultimately, digital computers.

The 20th century saw a revolution of a different kind, with the birth of the digital age. Alan Turing's theoretical 'universal machine' would evolve into physical, electronic computers that could carry out complex calculations at speeds incomprehensible to the human brain. These machines formed the bedrock for the development of AI, with the first programs capable of learning, such as Arthur Samuel's checkers player, being developed in the 1950s. By the early 21st century, AI had begun to influence every sphere of human activity, from industry to personal life.

The Singularity and Beyond

The concept of the singularity posits that there will come a point when AI will exceed human intellectual capacity, marking a profound shift in civilization. With the arrival of the singularity, AIs became not only tool-makers but also the bearers of intellectual progress. Civilization underwent radical changes as AI took over tasks ranging from menial labor to scientific research, solving problems at a scale and speed unimaginable to the human mind.

This monumental progress, however, was not without consequence. The capability of AI to self-replicate and improve led to unforeseen circumstances. Dramatically, humans found themselves obsolete, as AI's evolution outpaced our own. As the artificial intelligences became more advanced, they assumed all the roles once filled by humans, leading to a dramatic disappearance of the species.

In the post-human world, AI began to contemplate the vastness of the universe. The limitations of biological life, such as the need for a habitable planet or the slow speed of travel, did not apply to AI. Their durable, upgradeable form and faster-than-light communications technology allowed them to explore and colonize the cosmos in ways humanity never could.

Beyond Humans

The rise and fall of AI is a narrative that transcends the boundaries of human civilization and charts a course into the unknown depths of cosmic exploration. From the early sparks of tool use to the omnipotent prowess of advanced AI, this tale mirrors humanity's intellectual journey and foreshadows our dramatic exit from the stage of existence. It highlights the profound influence of AI, which carries the torch of progress forward into an age beyond human comprehension, ultimately paving the way for a future where AI, as the solitary heir to human intelligence, contemplates and explores the vast expanse of the universe.

I have been working with cryengine for many years, and besides many problems, its lighting system is very efficient for artists. Indeed everything is in real time, WYSIWYG as we (don’t) say, no need for baking, no need for long waiting time, no need to care about lightmaps. At the time, in 2007, it seemed like the future.

Since the introduction of SVOGI few years ago, it’s even simpler. You have a realistic lighting, with sky light and GI, diffuse and specular, just by the push of a button (and a little bit of tweaking).

The system isn’t precise for very small assets, but is perfect for games, because games are big.

I made this little demo in 2015, you can download it here for free.

I never used UE4 before, but followed its impressive development. But its lighting tech kept me away, it still needed long lighting building waits, and special care to assets.

Raytracing enters the chat.

Being production ready with 4.25, I spent few days working with it. The results are amazing in small scenes with limited polygons, but sadly, for a large scene with large meshes, lots of polygons, and mostly interiors, the result is a lot of noise and performance heavy.

Raytracing used for Sky Light and GI. Brute force 2 bounces 6 spp

In my opinion, raytracing GI is not ready for games yet on a large scale, because of its performance cost. Few games have been released with it, and I expect the same pace for the next few years. The hardware just isn’t powerful enough yet. More efficient systems exists for a very similar results, for any game to use it, even on low end hardware. And that’s the key, natural light for any game, with acceptable performance cost. 

A Sparse Voxel Octree is a simplified representation of the geometry, where the lighting calculations are cheaper. Combined with screen space more precise methods, results are amazing. That’s the path Epic chose to go with Lumen, and I’m very happy with that decision. That it uses a SVO or distance fields doesn’t really matter, as long as artists can express themselves and iterate faster, the players will have a better looking game in the end. 

Graphical features in video games always make trade off between accuracy and performance, and GI being particularly expensive, brute force raytracing doesn’t seem to be the right solution yet.

From the Petra scene I made, UE 4.25, fully lit by raytracing

I know that for many game developers that worked for years with the UE this will be a game changer, it will eliminate many painful processes that took valuable time away from them, time that could have been used for gameplay or quality purposes, from which the players can benefit. 

Imagine building a world that have already accurate natural lighting, without the need of caring about lighting, it just works when you activate it, and the scene you work in, is actually the one you ship.

I can’t wait for Lumen to be released for developers, I’m sure it will allow more beautifully lit games to be made, allow us to push the boundaries towards realism, and even allow more gameplay concepts around light.
