Скачать или смотреть Java Perspective 3D Rendering - first test

Small program I made for rendering 3D objects. Based on SWING. The 3D to 2D mapping is simple perspective projection, i.e. projection of point in space, in specified direction, towards a specified plane (the camera plane). The coordinates of the projected point in the plane is the coordinates of the projection point on the screen. The specified direction is a direction towards a point behind the camera plane. The direction is thus not the same for every point in the space, and the transformation is non-linear.


Lines can be drawn by associating two points with each other. When these have been mapped to the camera plane a line can simply be drawn between them on the screen. This is what is seen in the video.
