Creating complex environments and properties whilst enabling a high level of interaction within this environment requires a little sprinkle of magic.  

Real-time rendering takes first place when it comes to interactivity between the user and the virtual property while its pre-rendered partner has a decent gap lead-in graphic quality. 

Pre-rendered content is not interactive! Instead, it is the process in which static or video content is previously rendered on different equipment to the hardware that is outputting the playback of the content.  The greatest advantage of pre-rendered is the incredible quality of imagery in the end product.  Advancements in pre-rendering technologies now produce incredible graphic quality often seen in movies or TV shows.

The level of realism in pre-rendered content can be jaw-droppingly astonishing allowing accurate replications of existing or planned buildings.  But pre-rendered content has limitations as rendering these images can take considerable time and allow for zero interactivity.

Now, imagine you are virtually viewing your property and can change floor material.  Sample different oak flooring, change the time of day, explore how shadows reflect across your new oak flooring whilst the sun sets and as the sun rises.  Maybe you’d like to understand what a corner lounge would like in your living room, maybe it’s a new TV with surround sound units, maybe a new dining table.  Being able to customise a property and see those changes virtualised immediately requires real-time rendering.   

Like so many things in life, there is a trade-off when it comes to rendering images but what exactly do, we set out to achieve when adopting real-time rendering? 

The primary objective is to achieve the highest possible degree of photorealism at an acceptable minimum rendering speed.  This is usually 24 frames per second. That is the minimum a human eye needs to create the illusion of movement. 

Whilst there is a small trade-off in diminished realism when employing real-time rendering the advantages can be huge.  Users can plan, furnish and decorate their new homes – boosting buyer engagement.  Whilst real-time rendering is an emerging application in property marketing it is already proven in driving sales.

Deciding which rendering software can be tricky as both have inherent strengths and weaknesses.  Possibly a strategy employing both is the most beneficial.  The adoption of real-time rendering in property marketing is continuing to grow and fortunately, the gap between pre-rendering and real-time rendering is closing.  In time, real-time rendering will be able to very closely approximate the realism we see with pre-rendering.
