Easy, we have nothing to do with Hawking or Radiation. We will try to mimic black hole simulation we saw in the movie Interstellar. Now, actually there is no simulation, it's a simple, cheap trick, an illusion. But! After I reveal the trick, don't be ungrateful!!!Those are what we will do, give it or take. It doesn't depend on any specific 3D software or render engine. Applicable in every 3D platform.Now step by step :1 - Throw a sphere at the center of the scene. The material is black, no refle

In this subject, we will try to explain an advanced and complex topic. If you like to watch pictures, paint kids books and easily get bored from reading I recommend you to leave quietly.Today, it is impossible to imitate the exact behavior of light in nature, in terms of processing power. Many behaviors and attributes such as Reflection, Refraction, IOR, TIR, SSS, energy transfers (radiance) that we mentioned before can be physically programmed in a way that is close to nature. But in such a cas

In this article, we will try to explain the main features of the camera and especially the lenses, and the lens selections according to the conditions by explaining the commonly used terms.A modern camera is a digital image recorder working via the lens focusing scattered rays to the sensor and in the sensor a filter called Bayer seperates colors and sends photons to photosites in sensor then those photons are converted to digital data.Video cameras are devices that can record images at certain

Translucency is the superset of Transparency and Subsurface Scattering.With that in mind, in order to eliminate some conceptual confusion, it is necessary to include Opacity into the equation. Opacity (mass density of matter) is also inclusive on Translucency. So it goes like Opacity>Translucency>Transparency...There is an inverted relationship between Opaticy and Translucency/Transparency and Opacity is the dominant one here. We need to decrease the Opacity in order to achieve Transparency. Vic

In this article, we try to explain the interactions of light with various type of objects and the outcomes.In our previous article, we tried to explain the forming and qualities of light and colors with a bit of physics-based theory.Now we will dive a bit deep and try to explain some of observable qualities of light.When light interacts with an object, the most important factor of the outcome is the structure of the object. Light shows different interactions with air, water, soil, wood etc.. Obj

In this post, we will explain some of the basic theories of the generation and behavior of light and colors. We 3D Artists love every 3D software no doubt. As we ricochet from 3DS Max to Maya, Houdini, Unreal with our monkey appetite, we discover both similarities and differences of those softwares.However, some basic information is fixed in all software relied on physics. There are many constants such as light, color, reflection, refraction, opacity, transparency, sss etc. We will first try to
