After determining the main idea, the first step in design process is to build the initial product model by drawing lines and connection points. This process is modeling. “see in Persian”
After this step, the raw structure of the design is visible and each component will be refine and prepare for their own properties.
Now it is time to adjust the physical properties of the components. For instance a glossy objects other than their original color or texture, their reflectance. Or in the case of liquids, their density and viscosity, along with other variables, are important. Usually a product or part of it may have light transmission properties. So these characteristics should be considered in design process.
Now the shape and appearance of the products is ready. It is time to implement the main ideas and achieve the images. During this process, like a photography studio, lighting and camera settings become important. Everything about the effects of light sources and how to capture it in the real life, works here.
