Hace algún tiempo me llegó este interesante vídeo didáctico que estructura lo que es el videomapping 3D de forma muy amena. At other times we talked about the “Projection mapping“, defining a first approximation: Projection Mapping es el arte de utilizar proyecciones de imágenes que se adaptan a la forma de los objetos que se usan como… (leer más)
When we generate synthetic images and these have “defects” calling attention visible degrading the level of realism or say image perfection that have occurred “artifacts”.
Among the most basic devices are the so-called “Aliasing” that produce a feeling sawtooth on straight lines, due to the discrete character of the images.
LuxRender is a rendering engine based on the physical properties of light.
Has recently been made available to end users a new stable version, labeled 1.0, available on Windows platforms, Mac the Lynux.
LuxRender can generate realistic images, as we can see by visiting his gallery
The NASA official pages offer 3D models gallery free use, que pueden ser utilizados en nuestras animaciones. Los modelos se encuentran en diferentes formatos y grado de detalle: Blender, 3DS, OBJ. La lectura de estos ficheros de geometría 3D desde nuestras aplicaciones, You can assume the loss of detail in the… (leer más)
Lighting in Cycles is one of the aspects that differ with respect to the classical shading based on raytracing or raycast.
Point lights, contributing harsh shadows reducing the realism of the images, have given way to a model that approximates the actual light comportmiento a much more measured.
With the new model, Any object can be emissive and therefore act as a source of illumination in the scene.
A fluid animation (chocolate) of great artistic beauty with an interesting picture and sound installation that reveals the model used to create photorealistic images.
Like chocolate?
Interesting combination OvniVFX study in which simple is effective.
A test fluid realizable only by experts, desirable from the technical and visual.
The textures in Blender, with the rendering engine “Cycles”, may incorporate a channel named “Displacement” which provides a surface roughness.
There are two different techniques:
“Bump mapping” Mapped the topological
“Displacement mapping” or displacement mapping.
Image of a neuron, VCH-cobalt, of a bumblebee (“Blowfly”) female, situated in its visual lobe, that has been treated with visualization software to segment neuron model based on various parameters.
In this case, the neuron is colored highlighting varying the diameter of the filiform elements that compose (axon and dendrites).
In addition to the basic set of “shaders” incorporating “Blender” in “Cycles”, There is a special element that can combine two of them: “Mix Shader”.
The definition of a material, normally, will be conducted using two or more shaders on the same object. The main difficulty is to determine the properties needed to create the desired effect that simulates the behavior of the material to light.
Another “shaders” incorporating “Cycles” one Blender es “Glass”. Simulate glass and crystals, and other transparent surfaces,
The crystal is a medium that allows the passage of light (translucent) modifying its trajectory. It also reflects the light creating high gloss specular effects.
The lighting of a scene primarily used diffusion and reflection effects.
We have seen the basic shader using Cycles, called "diffuse", which is based on the model of Lambert or Oren-Nayar, based on the value that is used for the parameter "Roughness" ( 0 = Lambertian). This calculation model simulates the dispersion or diffusion of light on the material, but does not consider the effects of specular reflection that are associated with the model called “Glossy”.
