3D Rendered Image
This drawing technique is similar to the 3D sketch image as it also utilises a 3D model, but instead of giving the impression of a working proposal, can instigate a more finalized scheme that shows possible materials and colours.
This technique is usually used when a scheme itself is not under discussion, but rather the use of materials that will be visible or might interact with existing buildings.
Another opportunity for a 3D rendered image to be useful is when determining the impact of internal and external artificial and natural light on a scheme. It is important to understand how light and shadows will work with a building, as they can dramatically alter a design from one time of the day to another.
