+# CMU 15-462 : COMPUTER GRAPHICS
+
+## Descriptions
+
+- Offered by: CMU
+- Prerequisites: Basic vector calculus and linear algebra , basic C/C++ programming skills.
+- Programming Languages: C/C++
+- Difficulty: 🌟🌟🌟🌟
+- Class Hour: 100 hours
+
+This course provides a comprehensive introduction to computer graphics. It focuses on fundamental concepts and techniques, and their cross-cutting relationship to multiple problem domains in graphics (rendering, animation, geometry, imaging). Topics include: sampling, aliasing, interpolation, rasterization, geometric transformations, parameterization, visibility, compositing, filtering, convolution, curves & surfaces, geometric data structures, subdivision, meshing, spatial hierarchies, ray tracing, radiometry, reflectance, light fields, geometric optics, Monte Carlo rendering, importance sampling, camera models, high-performance ray tracing, differential equations, time integration, numerical differentiation, physically-based animation, optimization, numerical linear algebra, inverse kinematics, Fourier methods, data fitting, example-based synthesis.
