A terrain is similar to a bumpy plane that is infinite in two dimensions and defines an elevation along the third. First we create a matrix containing all the possible values of the coordinates of the mesh. The coordinates have x, y, z values.Then we build a mesh using the matrix values. Next we use createterrain () and createdesc () methods to create the terrain out of the mesh we have created.  Read More…

RAYCASTING is the use of ray-surface intersection tests to solve a variety of problems in computer graphics. It solves the general problem of determining the first object intersected by a ray or all the objects coming in the direction of a ray. It is an image order algorithms used in computer graphics to render three dimensional scenes to two dimensional screens by following rays of light from the eye of the observer to a light source. The high speed of calculation made ray casting a handy method for the rendering in early real-time 3D video games. The idea behind ray casting is to shoot rays from the eye, one per pixel, and find the closest object blocking the path of that ray - think of an image as a screen-door, with each square in the screen being a pixel. This is then the object the eye normally sees through that pixel. Read more…
