How 3D Game Rendering Works: Lighting and Shadows

The vast majority of visual effects you see in games today depend on the clever use of lighting and shadows -- without them, games would be dull and lifeless. In this fourth part of our deep look at 3D game rendering, we'll focus on what happens to a 3D world alongside processing vertices and applying textures. It once again involves a lot of math and a sound grasp of the fundamentals of optics.

The History of the Modern Graphics Processor

#ThrowBackThursday While 3D graphics turned a fairly dull PC industry into a light and magic show, they owe their existence to generations of innovative endeavour. This is the first installment on a series of four articles that in chronological order, take an extensive look at the history of the GPU. Going from the early days of 3D consumer graphics, to the 3Dfx Voodoo game-changer, the industry's consolidation at the turn of the century, and today's modern GPGPU.

How 3D Game Rendering Works, A Deeper Dive: Rasterization and Ray Tracing

In this second part of our deeper look at 3D game rendering, we'll be focusing what happens to the 3D world after all of the vertex processing has finished. We'll need to dust off our math textbooks again, grapple with the geometry of frustums, and ponder the puzzle of perspectives. We'll also take a quick dive into the physics of ray tracing, lighting and materials -- excellent!
