Which advanced graphics technique simulates the physical path of individual light rays to create realistic reflections?
diegoplays Paint glowing light onto flat shapes to learn how shading creates a 3D illusion.
diegoplays Normal mapping uses colored textures to trick light into bouncing off flat surfaces as if they were bumpy.
Who invented the shadow mapping technique in 1978 to calculate where light is blocked?
diegoplays Normal Mapping
Red, green, and blue, tell the light what to do! (Yeah, fake that 3D view!) / A flat purple sheet turns to cobblestone street! (Oh, it tricks you too!)
diegoplays Shadow mapping renders the game world from the light's point of view to find dark spots.
Which shading technique developed in 1971 interpolates light intensity across a polygon to make it look smooth?
Ray tracing history: Real-time ray tracing was so hard that it took nearly 40 years from its invention to run smoothly in games.
In what year did NVIDIA release its first RTX graphics cards, enabling real-time ray tracing in consumer video games?
What color channel data does normal mapping use to store the direction of fake bumps on a flat surface?
