Über dieses Buch

When multiple 3D objects overlap on a screen, how does the computer know which object is in front and which is hidden in the back? Early computers tried to solve this by drawing objects from back to front (the Painter's Algorithm), but this failed disastrously when polygons intersected each other. The ultimate, brute-force solution to 3D rendering was the invention of the Z-Buffer. The Z-Buffer is an invisible, mathematical memory array that assigns a specific depth value to every single pixel on the screen. Before the graphics card draws a new pixel, it checks the Z-Buffer. If the new pixel is mathematically further away from the camera than the pixel already recorded in that exact spot, the new pixel is brutally rejected and deleted. This textbook dissects the heavy VRAM cost of this constant depth-checking. We also explore the infuriating visual glitch known as "Z-fighting," where two surfaces occupy the exact same mathematical depth, causing the engine to aggressively and erratically flicker between the two textures. Understand the geometry of perspective. Learn how software engineers conquered the third dimension by violently assigning a strict mathematical depth to every dot of light on your screen.
