12th June

I reached the TCC hall at time when all my friends were marked absent for being late. I started my work in LibreCAD v3. In the evening, there was a presentation on inverse square root by Kaushal. This concept is used in 3D games when we are targeting someone in game and the distance can be easily calculated by this method. First of all we got familiar with what is distance, displacement and square root. Then he introduced about the “MAGIC NUMBER”.
