The site is https://convert.leiapix.com/upload Very simple to…

  • Example 4: What is a Dot Product?

    A dot product is another piece of math that you’ll find invaluable for game dev. It allows you to get a value between 1.0f and -1.0f that tells you the angle between two vectors and their relative orientation. This example shows the scale of the spheres on the end of the lines being set to…

  • Example 3: How to Move Objects in a Circular Motion in Unity
