ANSWER. Delete everything that doesn't affect the ray trace view. For example, if you are creating a ray trace of a kitchen on Floor 1, begin by selecting ... Turn off layers that are not seen in the ray trace view. Turn off Soft Shadows (Ray Tracing) for as many lights as possible. Avoid shiny ...
Speeding up Ray-tracing

Ray-scene intersection takes most of the CPU time (Whitted: up to 95%) scene composed of elementary solids –sphere, box, cylinder, cone, triangle, polyhedron, .. –primitive solids in CSG –number of elementary solids .. N naïve algorithm tests every ray (up to the proper recursion depth H) against every elementary solid

Optimisations. • Limit the number of rays • Make the ray test faster. – for shadow rays. • the main drain on resources if there are several lights. – for primary rays – for all rays. Over 90% of the cost of ray tracing is in ray-object intersection tests. Ray Tracing Acceleration.

Use bounding objects to fail fast. Project the scene at a first step (as common graphic cards do) and use raytracing only for light calculations. Parallelize the code.

components (plates, cylinders etc.) off which the ray reflects, diffracts, refracts etc. to get from the antenna to the observer position 2. SHADOW TESTS: determine if the path in 1 is "shadowed" by any components. This is the classic intersection tests in ray-tracing. 3. FIELD FINDING: if the path in step 2 is valid: apply the
12 Tips To Speed Up Your Rendering

1. Turn off Ray-Traced 3D. This is extremely important even though the ray-tracing function is something very innovative. However, if you want a fast render time, make sure you have a classic 3D setup before starting it. This can speed up the process up to two times!

Indirect lighting, the great advantage of ray tracing. Despite continuous improvements in GPU power and programmability over the past two decades, all of them use the same algorithm to render scene scenes, called the rasterization algorithm. This algorithm is good enough if we want to render scenes only with direct lighting, that is, with light ...

Go to: Tools -> Application Options -> Display, and untick "Show Origin 3D Indicator" & "Show Origin XYZ axis labels". then turn them on after render has finished.. Cheers. John. PS This took 7mins to render in window. UCS turned on Ray Tracing Set to High. Report.
