I am new to Rhino and the Rhinoceros Forums, but I could not find an answer to this particular question, pertaining to interior sun studies, or how light enters through windows.
I am attempting to study light in a single bedroom apartment, and have not been able to find a strategy online. My reasoning is to create a ceiling that is both transparent to the viewport, and which also casts shadows, but enabling any of these properties either in the materials, layers, or object properties (that being transparency and casting shadows) will give me an object that either lets all light in (thus, the visualisation is that of a room with no roof) or which is opaque and doesn’t let the viewfinder see into it - whether it casts shadows or not does not affect transparent materials. To get camera views of the interior light from different angles does not interest me, and I’m enquiring how to accomplish an interior sun study in plan view.
@Stefano_Dodaro this is currently not possible using Rhino render. Vray for Rhino does have this feature, so I thought to mention that, in case you have access to that.
I’ve added this as a feature request: RH-75825 Clipping plane should allow to affect geometry but not lighting
If it is your wish to do this type of work in rendered view, then I’ll write up another YT for that.
If you need it for an analysis you can try setting it up with Grasshopper and Ladybug. It’s a little complicated, but there are online tutorials to show how to set it up.
@arcus - Ladybug tools is a plugin which I was introduced to in school but have not yet used. I will dive into it eventually, but this project was bit too schematic. Thank you for posting the tutorial
@Gijs - Very informative. My graphics card is not quite to Rhino 7 spec, but I will try that. - This is the first time I’ve heard of Youtrack, so, I’ll look into that so we can be in the same frame of reference.
