Orientation Dependence - Modeling and Rendering
The outcomes of interpolated-shading models are dependent of the projected polygon's orientation. Because values are interpolated among vertices and across horizontal scan lines, the results may be different when the polygon is rotated. This consequence is mainly obvious when the orientation modifies slowly among successive frames of an animation. A same problem cab also happens in visible-surface determination while the z value at each point is interpolated by the z values allocated to each vertex. Both issues can be resolved through decomposing polygons into triangles. Instead, the solution is rotation- independent, although expensive, interpolation methods which solve problem without the requirement for decomposition.
Types of Graphic Images: Graphic images have been processed through a computer can generally be divided in two distinct categories. That image is either bitmap files or vecto
Q. Describe different types of parallel and perspective projection used in computer graphics.
What is reflection? The reflection is actually the transformation that produces a mirror image of an object. For this use some angles and lines of reflection.
Question 1: (a) How can you select and manipulate individual objects in a group? (b) How do you resize an object? Explain how you determine the point from which the object r
What is seed fill? One way to fill a polygon is to begin from a given point (seed) known to be inside the polygon and highlight outward from this point i.e. neighboring pixel
