7. Objectives, learning outcomes and obtained knowledge Introduction to visual informatics, including modeling, rendering, visualization, and programming on GPUs
8. Synopsis
1. Analytic geometry. Geometries in general: euclidean, projective, fractal. Analytic geometry of the euclidean space: point, vector, coordinate systems. Vector operations, meaning and implementation in  C++. Combination of points: line segment, line, circle parametric equations. Distance: implicit equations of the plane, sphere.
2. Geometric modeling. Curves with implicit and parametric equations. Free form curves: Lagrange and Hermite interpolation, Bezier approximation, Catmull-Rom spline. Parametric surfaces. Catmull-Clark subdivision surface. Poligon modeling with Euler operators.
3. Transformations: Projective space and homogeneous coordinates. Affine transformations (translation, scaling, rotation). Perspective. Wrap-around problem.
4. 2D rendering: Vectorization. Decomposition of polygons to triangles. Modeling transformation. View and projection transformations. Clipping. Line rasterization. Polygon filling.
5. GLUT/OpenGL 3: Syntax. Interfacing the windowing system. Window definition and event handlers. Retained mode rendering: Vertex array object. Vertex and fragment shaders in 2D rendering.
6. Optics fundamentals of 3D rendering: radiance, BRDF. Smooth materials, geometric optics, refraction, Fresnel equations. Rough surfaces: diffuse and glossy reflection. Colors.
7. Ray tracing: visibility problem. Surface normals. Shadows. Recursive ray tracing: mirrors and refractive surfaces.
8. Incremental 3D rendering: surface tessellation, modeling transform. Camera definition and perspective transformation. Clipping in homogeneous coordinates. Visibility algorithms: back-face culling and z-buffer algorithm. Gouraud and Phong árnyalás. Texture mapping. OpenGL/GLSL programming.
9. Animation: motion definition. Key-frame animation. Dynamics. Discrete event simulation. Collision detection and response. Character animation.
10. Games: virtual reality and game architecture. Avatar. Game engines. Billboards and particle systems. Terrain modeling. Character animation. AI.
