Noise Functions
In a Nutshell Noise functions are used to add variation. It is useful for making procedural oceans, terrains, forests & vegetations and so on. 1. White noise 2. Value noise 3. Perlin noise 4. Voronoi (Worley) 5. Fractal Brownian Motion White Noise White noise is one of the simplest of the noises, made up of…

3D Procedural World Generation
I was making my bird game & the player should be able to fly tens of kilometers to any direction, above the rich forests & deserts. There should be different species of birds flying in beautiful patterns and should interact with the world in a good way. I knew that the answer is procedural generation,…

3D Boat Physics
In a Nutshell When an object is submerged in a fluid, it displaces the surrounding fluid. This displacement results in the elevation of the fluid around the object. As the fluid is lifted against gravity, it gains potential energy. The source of this potential energy is the work done by the object in displacing the…

3D Airplane Physics
In this post, I’ll discuss simple 3D aerodynamics which can be used in video games & simple simulations. Forces on a Plane There are four important forces acting on an airplane. Weight This acts on airplane’s center of gravity, downward towards the center of the earth. It is constantly acting on a body. So with…
