ATMOSPHERIC EFFECTS SIMULATION |
摘要 |
The motion of particles such as snow is simulated in a computer generated image which represents the appearance from a predetermined viewing point of a three-dimensional worldspace through which the particles move. A three-dimensional model is defined which is made up from a regular array of abutting cubes of predetermined dimension. An object is defined which dimensions correspond to the dimensions of each cube, the object having characteristics such that it represents the motion of particles through the volume which it occupies. The three-dimensional model made up of the array of cubes is notionally positioned in worldspace such that the viewing point is located within a region of the model selected such that the field of view of particles from the viewing point is always within the model.
