Use ExportString for obtaining the output file as a String inside of Mathematica, then you can manipulate that string the way you want: prepend another string with StringJoin, change the string with StringReplace etc. Finally you can simply Export that string as "Text" into a file with any extension you like.
How do i do ray tracing in mathematica? : Mathematica
https://www.reddit.com/r/Mathematica/comments/3qurnf/how_do_i_do_ray_tracing_in_mathematica/
I implemented a ray tracer in Mathematica using the OpenCL framework. The 3D models weren't imported - they were coded by hand. As u/sandwichsaregood pointed out, you may find it more efficient to use a 3rd party tool. If you must implement the ray tracer yourself then I suggest you get reading. 2 level 2 MSZH Op · 6y
Why is raytracing so slow? - Mathematica Stack Exchange
https://mathematica.stackexchange.com/questions/219629/why-is-raytracing-so-slow
The ray-tracing task in general is just searching for reflection angles and corresponding interaction points. As it was pointed out by @MassDefect, the faster way is making these calculations as it is without any Region 's.
Ray Tracing for Points in a Polygon - Wolfram ...
https://demonstrations.wolfram.com/RayTracingForPointsInAPolygon/
In computational geometry, there is a classical problem of partitioning a set of points in 2D into those enclosed by a polygon and those outside. Currently, the best known way is a ray-tracing method, in which a ray is drawn from a candidate point in the positive direction and the number of intersections with the polygon is counted.
Mohammad Alaggan: Ray tracing with Mathematica ;)
https://mohnabil.blogspot.com/2010/02/ray-tracing-with-mathematica.html
The road to success is full of bumps. The more bumps you hit, the closer you are to your goal. The more bumps you get in a short interval of time, that faster you are heading to you goal. Abstraction is one way of escaping your problems by assuming someone have solved them for you. Computer scientists are those people who knew why computer ...
Lens Lab--A Demonstration of Lens Ray-Tracing with ...
https://library.wolfram.com/infocenter/MathSource/655/
Description This notebook is an example of using Mathematica for doing geometric ray-tracing. LensLab defines a set of functions for designing optical systems, including lenses, mirrors, prisms, and other elements. The notebook can compute ray paths through the elements and plot the results in two and three dimensions.

Optical ray tracing can be sequential or non-sequential. The ray-tracing engine can even perform traces with arbitrary precision, beyond standard machine precision. Here is just a bit of what you'll find in Optica's vast library of predefined elements: 122 optical components 38 lenses 23 mirrors 22 prisms 12 light sources 22 high-level functions
