The Lumion workflow environment provides architects with a real-time preview of your visualisation scene.
Simple, easy to learn, focused on the task and not clutered with deep menus and deep features that takes months to learn.
The Difference Between Real-time and Traditional Raytraced Systems:
Uses the high performance of the GPU with massive parrallel processing to render.
Alternative methods to simulate light, shadows and global ilumination.
Rapid scene creation and rendering in a dynamic, real-time, interactive environment.
A quality image can be rendered in less than a minute.
By the time someone has used a raytraced method to produce 1 or 2 images, someone else has not only produced 4 quality images, but also a 2 to 3 minute expansive video animation for the client.
Uses the CPU with limited processors compared to the GPU.
Raycasting to generate images is very time intensive, but produces a higher quality result than current real-time implementations.
The quality can be made to look 'photo-realistic'. If that's the essential feature, that's fine.
It can take anywhere from 15 minutes to 4 hours to generate a single photo.
The quality of a scene is determined first by the skills and abilities of the designer to meet client ideas. Then by the interpretation of those in to a 'story' that provides the visualisation message needed by the client. Technology is the tool, not the designer.
