And no fast renderer can fake scattering well.Įven unbiased renderers aren’t perfect simulations, as they don’t model diffraction (with very specific exceptions).Įxploring A New Frontier: Desktop EDM Is Coming 24 Comments Standard renderers can fake some of that (with tricks like ambient occlusion), but you have to tell them how the image should come out, rather than the software telling you. So if you’re an architect or interior designer, you can see what it would *actually* look like to have a space lit by, say, an Erco 30 degree halogen spot plus indirect sunlight bounced off plaster walls. The common technique that comes closest is ray tracing, which asks “what paths can light take from the light source(s) to this pixel?”, but in reality, the question is “where do the photons from the light sources end up?” For nearly all photons, the answer to that question is “not at the image plane”, which means unbiased rendering spends most of its time on calculations that don’t end up directly affecting the image.īut the advantage is you can model scattered light, and quantitatively calculate the contribution from different sources. I say unbiased renderers “really do” simulate light, because most renderers don’t. This idea is not at all new – “unbiased rendering” systems like Maxwell, which really do simulate light, include detailed simulations of real optics and film stock, and give fantastic results at the cost of unbelievably long rendering times. Posted in digital cameras hacks Tagged blender, film camera, simulation Post navigation We love this video, take a look at it below the break. We can’t say all of them remove the feel of a rendered image, but they certainly do an extremely effective job of simulating a film photograph. It’s an absurd level of detail but it serves as both a quick run-down of how a film camera and its film work, and how Blender simulates the behaviour of light.įinally we see the camera itself, modeled to look like a chunky medium format Instamatic, and some of its virtual photos. The development of the camera mirrors that of the progress of real cameras over the 20th century, simulating the film with its three colour-sensitive layers and even the antihalation layer, right down to their differing placements in the focal plane. Starting with a simple pinhole camera he moves on to a meniscus lens, and then creates a compound lens to correct for its imperfections. The point of a rendering package is that it simulates light, so it shouldn’t be such a far-fetched idea that it could simulate the behaviour of light in a camera. Instead, he’s simulating a colour film camera in extraordinary levels of detail within Blender itself. But not by taking a picture of your monitor with a camera. So just how do you make a perfectly rendered scene look a little more realistic? If you’re, you take a photograph. Blender is a professional-grade 3D-rendering platform and much more, but it suffers sometimes from the just-too-perfect images that rendering produces.
