Researching Photoreal Cardboard and Other Materials Rendering
I have collected a few images below from websites that upload photoreal rendered images. I am mainly concentrating on observing the behaviour of cardboard material after its been rendered in mental ray or vray. The reason I am looking at other matreials is to understand the light information required to provide an effective realistic image. The image below of a kitchen is the perfect combination of different materials that behave differently to each other . It shows how cupboard wood reflects less light than the wood on the floor. A shiny shader is used on the floor to give it the laminated effect and that’s why it reflects more light than the wooden cupboards. Reflection has also been added to the floor to truly acquire the characteristics of a real laminated flooring.
The image below is a sketch of a 3D representation of cardboard boxes. This would assist the artist to visualise what they want to achieve after the boxes have been modelled in 3D.
Below is a carry-case box with it’s lid upside down on top. It seems as though the person who has created this has used the right concept art to the UV maps, so it it can almost be mistaken for a real box. However if I look closely and observe the corner of the lid where the cardboard has supposedly been cut, it can be seen that the details are being slightly stretched. The entire image also looks slightly grainy also making it unrealistic.
I was analysing the images below to understand how different shaders and textures reflect light differently. The material imitated below are a ceramic cup and saucer, coffee, spoon and table. These objects are in focus where as the objects in the background are out of focus; this help the audience to focus on the main objects. I think that is a good technique to present the main object in a photorealistic image.
I think the image below looks real because of the refraction’s added to the spherical onaments on the table to distort the reflection of the objects surrounding the spherical objects. As mentioned reflections have been added to the spherical object to give the illusion of a glass or ceramic like material that reflects its surroundings. Shadows are important because it is one of the elements that help viewers to understand what is realistic and what is not. There is a lot of shadow added to all the objects it seems and this contrasts well with the amount of light applied to the objects to illuminate them. I like the spherical objects most because they have so much detail added to them and they do imitate real spherical objects. In the background I think the wooden stationary boxes and holders work well to contrast against the reflective spherical objects. Especially the pencils, which look assorted and not arranged in any order; this is what provides the illusion that the objects presented in this image are realistic. The curtains look real because of the creases and amount of mixed light and shadows make it difficult to believe this image was produced in a 3D software. Maybe the curtain was added later to the completed image but I can understand how every other object in this image was created in 3D.
