RGPV CS603(B) Unit 3 study material covering 3D transformations, parallel and perspective projection, hidden surface elimination, Z-buffer algorithm, Bezier and B-Spline curves, illumination models, Phong shading, Gouraud shading, ray tracing and color models.
Unit 3 explains how three-dimensional objects are represented, transformed, projected and rendered on a two-dimensional screen. This unit is very important for understanding realistic graphics, shading, curves, hidden surface removal and color models.
Learn 3D transformations, projection techniques and hidden surface elimination.
Understand illumination models, Phong shading, Gouraud shading and ray tracing.
Study Bezier curves, B-Spline curves and color models like RGB, CMY, HSV and YIQ.
Complete syllabus-based topics of Computer Graphics & Visualization Unit 3.
Translation, rotation, scaling, reflection and composite transformations applied to three-dimensional objects.
Moving a 3D object from one location to another by changing its x, y and z coordinates.
Rotating an object around x-axis, y-axis or z-axis using transformation matrices.
Increasing or decreasing the size of a 3D object along x, y and z directions.
Projection technique where projection lines are parallel and do not meet at a point.
Projection method that gives realistic depth by making distant objects appear smaller.
Techniques used to remove surfaces that are not visible to the viewer.
Depth-based hidden surface removal technique that stores depth information for each pixel.
Parametric curves controlled by control points and widely used in CAD, graphics and animation.
Smooth curve representation that offers greater flexibility and local control.
Mathematical models that simulate the interaction of light with surfaces.
High-quality shading technique providing realistic highlights and smooth surfaces.
Vertex-based shading technique that interpolates colors across polygon surfaces.
Rendering technique that traces rays of light to generate realistic images.
Additive color model based on Red, Green and Blue components.
Subtractive color model based on Cyan, Magenta and Yellow colors.
Alternative color representation models used in image processing and television systems.
