Does scale affect the Ray-detection?

Code Select Expand


mRoad.scale(5);
SimpleVector d = new SimpleVector(0, -1, 0);
float frontHeight = mRoad.calcMinDistance(front, d, 100 * 30);
mRoad.setScale(1);

SimpleVector d = new SimpleVector(0, -1, 0);
float frontHeight = mRoad.calcMinDistance(front, d, 100 * 30);


Are the 2 codes above equal or not?  What's the situation when invoking mRoad.enableLazyTransformations()?

No, they are not equivalent. The result might be the same if the scale doesn't change the height of the road but in any other cases, the scale will affect the outcome.
Lazy transformations don't change the outcome.
