How to simulate human vision ?

[DeepSOIC]

The simplest (but maybe not optimal) method is probably to directly tamper then restore the global FC parameter with something like

Code: Select all

FreeCAD.ParamGet("User parameter:BaseApp/Preferences/View").SetBool("_PARAM_",_VALUE_)

Yes, but it's only a part of the problem. Navigation style may need to be reapplied to fetch the parameter, otherwise it may not be detected. I'll experiment with it later.

Wouldn't that be good to automate the display parameter change?

Done! Turns out, there is no need to reinstantiate navigation style, it does react immediately.

My real model is an assembly. The image below is just a drastically simplified illustration of a flat dashboard and a steering wheel.

Boolean operations can't resolve the problem, what is required is clearly a projection mechanism. I know almost nothing about rendering technique and never used such a tool (I'm more into pure engineering). Does a rendering tool can fully compute projected shadows and is it possible to disable the diffusion mechanism into a scene, thus having a neat difference between illuminated areas and shadows ?

As I said I'm a total newcomer to this field, but it seems ray-tracing can do the job. I suspect our binocular vision brings some subtle differences but this is probably a very similar problem, and RT can yield an accurate approximation. Concerning the RT workbench, it would be convenient to set the light source(s) directly into the scene (using a point and a vector) with an interactive tool (something like the tool for moving a part.) And also directly edit the parameters using a panel.
