Picture Ray Tracing Picture Ray Tracing

For achieving an even higher image quality or generating high resolution images of your model, MOSES supports exporting to a ray-tracing program. Ray tracing calculates the path of every beam of light in your scene, making it a very computationally intensive process, but one that can handle reflections, refraction, and transparency correctly, as opposed to the approximations we make in the normal 3D display in order to give users a smooth, interactive experience.

To export a scene for ray-tracing, it is recommended (but not required) that users first visualize the scene in MOSES's 3D viewer. Once the scene is positioned correctly, issuing the command:

     &PICTURE -RENDER RAYTRACE -SAVE

will generate a file in the .ans directory called povxxxxx.pov which can be loaded and run by POV-Ray by double-clicking on it. If double-clicking on the file does not open POV-Ray, you need to download and install it from here The downloads are about half-way down the page.

Once you have it installed, double-clicking the .pov file should open it. Hit the Run button in POV-Ray to begin the render. For better quality, we recommend going to the menu and selecting "Render->Edit Settings/Render" and selecting the last option under "Section:" [1280x1024, AA 0.3].

For those looking for an even more realistic rendering, you can use the &PICTURE option



     -W_FANCY, YES/NO

This option with YES/NO of YES will render realistic small waves when there is no sea specified.

After installing POV-Ray, command line users can directly operate on the pov00001.pov file by executing something like the following:

     povray -ipov00001.pov -w1024 -h768

This would take input file pov00001.pov and render it at 1024x768. For further options, see the POV-Ray documentation.
