How to scale sprites with perspective shift?

Question

3D

Here, let's say

float centerX, centerY;
float offsetX, offsetY;
for (float i=0; i<10; i++){
scaleX=scaleY=i/10;
putSpr(centerY+offsetX*i, centerY+offsetY*i, scaleX, scaleY);
}

How in this case to make a more natural imitation of perspective? Not linear scaling, but exponential.

Answer 1

I would draw a top view on a piece of paper and in this 2D projection I would indicate not the center of the sprite and its width, but also the camera point at the bottom of the piece of paper. There, already in geometry, you can write a formula.
