• Helical Interpolation Programming Examples

Well I took it upon myself to read about linear interpolation today, since I found some 'lerp' code in the Irrlicht engine and realised how useful it is in the domain of computer graphics.I almost completely understand it tooAnyway, I read wikipedia's article on bilinear interpolation and sort of understood that too. But what can you use it for in computer graphics? Can you use it in computer graphics? There's a pretty picture in the article.I googled 'bilinear interpolation in computer graphics'. What the hell is a 'pyramid filter'? Wikipedia has no answers and the google results for that confuse me. The subject of interpolation (in any form) in computer graphics is huge, so I'll try to give a general overview and if you want to know something specific, feel free to ask.In general, interpolation helps us to find the value of a data set or a function, between two points, using those points as indicators.

Helical Interpolation Programming Examples

In the case of linear interpolation, if you have two points (x1, y1) and (x2, y2), you can calculate the interpolation coefficient alpha which varies between 0 and 1. If the coefficient is 0, you are at the starting point, if the coefficient is 1, you are at the ending point.Let's try to find a very basic example for linear interpolation (although the result would be horrific with the linear approach): you want to move an object in 2D along a predefined path, that you can't or don't want to describe at a function. So you go ahead and define a limited number of points, each point has additionally to its coordinates a time value (to see where the object is at what time.If you are running your program and the animation begins, each cycle of the loop you'll increment the time value by the time that passed since the last frame and you'll try to calculate the position of the object from there. Let's say we have the following:Point1: x1,y1 and t1Point2: x2,y2 and t2Now during your animation cycle you end up with a time value t, with t1.
