Rendering is the process of creating an image from a model by means of software. Rendering gives the final appearance to models with visual effects, such as shading, texture mapping, shadows, reflections and motion blurs.
Why renders are important in an architectural project?
Understanding traditional 2-D floor plans and elevations can be difficult.
It helps you avoid paying for work you don’t want.
Design review boards generally respond positively to presentations that include 3-D render.
Understand what the space will look and feel like, which is where 3-D design comes in.
In case you don't have the 3D model, make sure you check the gig extras.
