GAMES101-01 Introduction

what

The use of computers to synthesize and manipulate visual information.

it applied in vidio Games, Movies, Animations, cad/cam/cae Desigh, visualization, virtual reality, digital lllustration, simulation, gui, Typography.etc

why

Fundamental Intellectual Challenges

• Creates and interacts with realistic virtual world
• Requires understanding of all aspects of physical world
• New computing methods, displays, technologies

Technical Challenges

• Math of (perspective) projections, curves, surfaces
• Physics of lighting and shading
• Representing / operating shapes in 3D
• Animation / simulation

Topics

Rasterization

• Project geometry primitives (3D triangles / polygons) onto the screen
• Break projected primitives into fragments (pixels)
• Gold standard in Video Games (Real-time Applications)

Curves and Meshes

How to represent geometry in Computer Graphics

Ray Tracing

• Shoot rays from the camera though each pixel
  • Calculate intersection and shading
  • Continue to bounce the rays till they hit light sources
• Gold standard in Animations / Movies (Offline Applications)

Animation/Simulation

Not about

• not about OpenGL/DirectX/Vulkan
• not about shaders
• not about 3d modeling. suach as mata/blender
• not about cv/deep learning
