nice video.but in an exam time is limited,i need a FAST SOLUTION and here it is: provided that we have a linear system as the video suggests, step1=> (t=20) - (t=15) = 5, so five steps from 15 up to 20 step2=> (100%)/5=20% , yes it is number 5 from step one step3=> v(16)=362.78+20%(517.35-362.78)=393,69. BAM! so fast! the secret behind step 3: from number 362.78 move up by 20%. WHY 517.35-362.78? Because, 517.35-362.78=154.57 which corresponds to 100% increase from 362.78,but i want only 20%.

Just use linear newtons' divided difference polynomial. Given (x1,y1) and (x2,y2) as two data pairs, the straight line equation is y=(y2-y1)/(x2-x1)*(x-x1)+y1

@Doctorwhorage The linear direct method is to setup the basis for doing direct method interpolation using higher order polynomials. You should look at the Newton Divided Difference polynomial method playlist at the numericalmethodsguy channel for your approach!

An excellent resource for demystifying the general fog around especially "cubic (Hermite) curve interpolation" is this one by "Nils Pipenbrinck" which comes up right away in any Google search and consists of about 2, mostly blank, pages. But here it is anyway: cubic.org/docs/hermite.htm . From Hermite curve interpolation between two points he constructs a semi-generalized cubic spline algorithm that any school child should be able to understand. The famed "Catmull-Rom" spline being a special case said splines.

@DaruiAkaBlackNinja It is a straight line in this case, but let's not confuse regression with interpolation.

@YoZZgAtLiii66 Solve the two equations and two unknowns. You could use Gaussian elimination method. Go to numericalmethods(dot)eng(dot)usf(dot)edu and click on Keyword> Gaussian Elimination > Textbook chapter.

Oh ya instead of doin ur method we can just use slop formula y2-y1=m(x2-x1) solving for m then choosing the neart point and substitutin in this Eq. y2=m(x2-x1)+K where K is the wanted value am i right ?? :D

Does anyone know how this applies to alpha blending with lerp?
@MiljanBojovic10 жыл бұрын
Alpha is usually a float value from 0 to 1 in blending functions. So Alpha is basically the position between A and B. Let's say you have: A=50 and B=100. if your alpha is 0.5, then you'll get 75, because 0.5 is half of Alpha value which leads to a result that is the value that stands in middle of A to B. I hope this helped. I guess you are blending textures, so Alpha value will make the pixel at a certain position of both texture to find a middle value... still if your Alpha is 0.5. if Texture A is white and B is Black, then the Alpha of 0.5 will give you a grey pixel. :)
