How are video game graphics created?
Video game graphics are crafted using stunning visuals that form detailed virtual environments. These graphics are composed of millions of vertices and triangles, each with specific colors and textures. The computer's graphics card processes these graphics, which are essentially made up of ones and zeroes. The rendering pipeline for video game graphics involves three main steps: Vertex Shading, Rasterization, and Fragment Shading.
What is the process of Vertex Shading in video game graphics?
Vertex Shading in video game graphics involves transforming objects in 3D space to a 2D view screen using camera perspective. This step is crucial in creating the visual representation of objects in the game world, allowing for accurate positioning and scaling of elements within the virtual environment.
How does Fragment Shading contribute to video game graphics?
Fragment Shading in video game graphics plays a vital role in creating realistic scenes by accurately shading each pixel with appropriate lighting. This process calculates shading based on the direction of light and the surface normal of triangles, ensuring that the visual elements in the game appear lifelike and immersive to the player.

Graphics Rendering Techniques and GPU Innovations
- To achieve smooth shading in graphics, surface normals are calculated for each vertex by averaging the adjacent triangles' normals. Barycentric coordinates are then used to create a gradient of normals across a triangle, resulting in pixel-by-pixel coloring and smooth shading on curved surfaces.
- Ray tracing is utilized in graphics rendering to create detailed scenes with accurate lighting and reflections, commonly seen in TV and movies. DLSS, on the other hand, upscales low-resolution frames to 4K using a convolution neural network after ray tracing, enhancing visual quality in video games.
- The latest GPU generation features distinct computational resources: CUDA cores for graphics rendering, ray tracing cores for detailed scenes, and Tensor cores for DLSS upscaling. Utilizing all cores simultaneously allows for rendering frames in less than 10 milliseconds, significantly faster than relying solely on CUDA cores.
