Not all morph target animation has to be done by actually editing vertex positions. It is also possible to take vertex positions found in skeletal animation and then use those rendered as morph target animation. An animation composed in one 3D application suite sometimes needs to be transferred to another, as for rendering.
In 3D computer graphics software, vertex painting refers to interactive editing tools for modifying vertex attributes directly on a 3D polygon mesh, using painting tools similar to any digital painting application but working in a 3D viewport on a perspective view of a rotated model.
Blender 4.3 splash screen. Blender is a free and open-source 3D computer graphics software tool set that runs on Windows, macOS, BSD, Haiku, IRIX and Linux. It is used for creating animated films, visual effects, art, 3D-printed models, motion graphics, interactive 3D applications, and virtual reality. It is also used in creating video games.
The vertices of triangles are associated not only with spatial position but also with other values used to render the object correctly. Most attributes of a vertex represent vectors in the space to be rendered. These vectors are typically 1 (x), 2 (x, y), or 3 (x, y, z) dimensional and can include a fourth homogeneous coordinate (w).
When a group of vertices (normally 3, to form a triangle) come through the vertex shader, their output position is interpolated to form pixels within its area; this process is known as rasterization. Optionally, an application using a Direct3D 10/11/12 interface and Direct3D 10/11/12 hardware may also specify a geometry shader.
A renderer can simulate a wide range of light brightness and color, but current displays – movie screen, computer monitor, etc. – cannot handle so much, and something must be discarded or compressed. Human perception also has limits, and so does not need to be given large-range images to create realism.
In shading, a diffuse component of light is the light reflected from the surface uniformly into all directions. This component depends on the surface normal and direction to the light source but not on the viewer's position. Direct3D Microsoft Windows 3D API, with similar architecture to OpenGL. Displacement mapping
Z-buffering is a technique used in almost all contemporary computers, laptops, and mobile phones for generating 3D computer graphics.The primary use now is for video games, which require fast and accurate processing of 3D scenes.
