I'm trying to model a following scene:
It's a project of a simple DIY projector:
- on the left, there's a smartphone or just something with a light-emitting display (LCD, AMOLED). Just to clarify the model: it can display various images, not just emit plain white light,
- in the middle, there's a lens which has a certain factor or refraction,
- on the right, there's just some matte (like a wall) surface where the image from the LCD should be visible after passing through the lens.
I'm a beginner in 3ds max when comes to raytracing stuff. I know how to model the placement of the elements, but I'm not sure how to configure the whole raytracing thing in order to make it work like this. Please give me some general pointers, e.g. what kind of surface I have to set to make it emit light (in fact, it should be a light-emitting texture? not sure) and also what kind of material/surface to choose for "receiving" light.
