    Coordinate Space Transformations

    You are right. The matrix goes first. But the api i use needs the vector first.

    Coordinate Space Transformations

    Hi, Afters many hours of analyzing and proving, i finally i got the formula and logic behind. I consulted many books but the only one i found it talks explicity about this is "3d math primer" , but even they do not explain the whole process. First, for transforming from object space relative...

    Coordinate Space Transformations

    Ok thinking a bit more of the problem, it seems that the real operation is that they use the transpose of the rotationYmatrix So the equation seems to be like this: resultingPoint = (RotationMatrixAroundY(angle) * ObjectA ) + (RotationMatrixAroundYTransposed(angle) * ObjectBPoint) It...

    Coordinate Space Transformations

    Hi Chiro, thank your for your welcome. I understand matrix operations. But this specific process isn't clear to me. Also I don't need code, only the math. In the example i posted, for converting the objectB point position transformed into objectA object space, its seems that objectB is first...

    Coordinate Space Transformations

    Hi, I hope this is the right forum to post. My question is, which is the math implied for transforming an objectA local space, to anothers objects local space, and then transforming it to world space? For example, Lets say we want to know if objectA is infront of objectB, So the...
