So, I have been working on some code with a group of people/organisations etc. and I've hit a small bump in the road that I thought someone on here may be able to help me with I have developed some code that draws 3D towers to represent the amount energy particular objects have, thus creating a sort of graph. I am currently using a very basic linear scaling algorithm but I wish to use a logarithmic method of scaling. Currently my algorithm does the following: NB: I only scale in x, y as z is the height and represents a completely different thing. 1: Calculates the centre point of the object 2: Calculates the distance between the centre and each corner 3: Divides this by the data collections maximum/highest energy 4: Multiplies this by the current objects energy 5: Adds this final value to the centre point e.g. corners.x = centre[0] + ( ( ( corners.x - centre[0] ) / max ) * energy ); corners.y = centre[1] + ( ( ( corners.y - centre[1] ) / max ) * energy ); In effect this scales the objects in proportion to the maximum recorded energy for a given data collection (a sort of percentage). I wish to use a logarithmic scaling method to do the same thing but I am not sure how I would do this. I am not all that great when it comes to Maths but particularly when it comes to logarithmic scaling in C++.....I would appreciate if someone could give me a hand with this. In particular coding examples in C++ would be very useful Thanks in advance
