Simulation of a Rotating Propeller

Simulated Motion Blur

part I

Objects: "sphere", "cylinder".
Methods: "#declare", "#macro", "#while", "#if",
                    "union", "intersection", "difference", "texture_map"


This sample shows the simulation of the motion blur of a rotating propeller by a disc with a partial transparent radial texture. It is possible to activate or deactivate this by a #if statement. It also shows how to make the rotation angle variable (i.e. for animations). The number of propeller blades and their length are freely to decide because of a consequent use of #macro statements.

The Construction in details:

The construction is shown by the following steps:

Step 1: How to make a propeller with a variable number of blades and a variable rotation angle.
Step 2: How to simulate the motion blur of rotating blades.
Step 3: How to build a simple casing for the engine and putting this all together.
