Web Reference: Wolfenstein 3D Game Engine implemented in java using only standard libraries (Java2D, AWT, Swing and Java Sound API), so no external libraries is required. The current version supports only the Shareware version. Given a point and a polygon, check if the point is inside or outside the polygon using the ray-casting algorithm. A pseudocode can be simply: Where the function ray_intersects_segment return true if the horizontal ray starting from the point P intersects the side (segment), false otherwise. To find the first wall that a ray encounters on its way, you have to let it start at the player's position, and then all the time, check whether or not the ray is inside a wall. If it's inside a wall (hit), then the loop can stop, calculate the distance, and draw the wall with the correct height.
