Language: C++ with MFC Here's a mathematical question you can ask yourselves: can you scale an object without using multiplication? I have an object (coordinate plane kept at standard Windows with (0,0) as the upper left corner, and the y axis inverted) that I'd like to resize. Because the resizing will be very small and gradual in amount, and important number changes would be lost to rounding, I'm wondering if it's possible to scale it up using addition and subtraction of the points....or would multiplication be easier? ______________ Next, I keep hearing about pixel-testing for collision detection. I get the concept, but how is it done quickly, accurately and w/o errors? I don't understand how pixel by pixel testing works or how to make it work. thanks
