The texture bitmaps produced are comparable to those reproduced with output devices. The "renderer" in 3D software is part of the software. Its function is like shooting a 3D scene through a virtual camera to get some distant relations, light shadows, and texture data about the 3D scene. Then the “replicator†takes a digital “snapshot†of the scene, which is somewhat like the process of imaging the light through the lens of the camera, and by collecting the data of the scene to characterize the texture, light, shadow, and distance relationship of the scene. The more advanced the copying code in the 3D software package, the better the image and animation effects. Some less expensive 3D packages are: POV-Ray (available for download), metaCreations Bryce4, Hash Animation Master7.1, auto-des-sys Form-Z 3, Real3D 3.5, Maxon Cinema 4D/XL5.5, NewTek LightWave 5.6 and Discreet 3D Studio Max 3 use these software to generate more realistic results.
The ability to copy is also divided into several levels, each of which uses a different texture-generating algorithm when processing the data acquired by the virtual camera lens. For example, the Gouraud shading method is sometimes used as a method for previewing the effect of copying. The Phong shading method is a more complicated algorithm. The support for generating a highlight part is added to make the scene look smooth and flashy. The coloring algorithm also has For algorithms that produce metallic luster, the Raytracing algorithm causes the light to refract and reflect on the crystal or water surface, creating a surrealistic feeling.
Radiosity is a better algorithm than raytracer. Radiosity takes into account the color of the light reflected from a colored object, so the color reflected by a red ball is actually a transition from pink to white. This slight change in light makes the image more realistic. Form-Z 3 software is the Radiosity algorithm used, and Animation Master 7.1 simulates the Radiosity algorithm in its Raytracing shader.
Raytracer is currently the most common method of copying, it can explain different parameters and then generate different types of bitmaps. The types of bitmaps produced are: bitmaps with irregular bulges (the height of the bulges can be controlled using information in the images), bitmaps with transparent or opaque effects (controls the degree of transparency of the gradation images, usually White is completely opaque and black is completely transparent), bitmaps of glossy objects (controls how much light the object emits, simulates the effects of neon, flame, and explosion), diffuse or reflective bitmaps, and Image bitmap (allows the user to control the direction of light reflection on the surface of the object). These options can be found in most 3D packages, and they can be used together to achieve the most realistic results.
Texture Generation - Really reproduce the texture of the image with 3D tools
The initial stage of creating a 3D image or animation process is to create a character's attributes using a 3D model, or to set a character's actions in 3D space. Once the 3D models and their action settings have been completed, the designer's attention will focus on the image's texture or the "skin" of the model within the scene. The generation of textures is very simple: just paste a 2D image on the 3D model as skin. In fact, this does not achieve the desired effect - that is, it can not achieve the photo-realistic effect. For example, making a lizard or frog may require a series of texture layers and stickers to achieve more realistic results. Texture production is an art form that can be realistically textured using some powerful and sophisticated software tools.
