这是渲染引擎的自然输出，RGB通道表示朝向观察者的光线的量，也表示有多少从背景来的光被阻塞。OpenEXR的文件格式使用这种alpha类型。因此，用于渲染和合成的中间文件通常存储为预乘alpha。

• （直通型/预乘型）Alpha转换
• 两种 alpha 类型之间转换不是一个简单的操作，并且可能涉及到数据的丢失，因为两种alpha类型都可以表示对方无法表达的数据，尽管其中的差异很微妙。

可以将直通型alpha当作是一张带有单独透明遮罩的RGB颜色图像。在该遮罩完全透明的区域中，RGB通道也可能有颜色。转换为预乘型alpha后，这个遮罩被应用，这些区域的颜色变成黑色，造成数据丢失。

另一方面，预乘型alpha可以同时表示自发光与来自背景中透射光的渲染。例如，一个透明的火的渲染可能会发光，但也让来自它其背后物体的光线穿过。当转换为直通型alpha后，这种效果将消失。

• Display Referenced
• Refers to an image whose Luminance channel is limited to a certain range of values (usually 0-1).The reason it is called display referenced is because a display cannot display an infinite range of values.So, the term Scene Referenced must go through a transfer function to be convertedfrom one to the other.

• Manifold meshes, also called water-tight meshes, define a closed non-self-intersecting volume(see also non-manifold). A manifold mesh is a mesh in which the structure of the connectedfaces in a closed volume will always point the normals (and there surfaces) to the outsideor to the inside of the mesh without any overlaps. If you recalculate those normals,they will always point at a predictable direction (To the outside or to the inside of the volume).When working with non-closed volumes, a manifold mesh is a mesh in whichthe normals will always define two different and non-consecutive surfaces.A manifold mesh will always define an even number of non-overlapped surfaces.

• 'MIP' is an acronym of the Latin phrase 'multum in parvo', meaning 'much in little'.Mip-maps are progressively lower resolution representations of an image,generally reduced by half squared interpolations using anti-aliasing.Mip-mapping is the process used to calculate lower resolutions ofthe same image, reducing memory usage to help speed visualization, but increasingmemory usage for calculations and allocation. Mip-mapping is also a processused to create small anti-aliased samples of an image used for texturing.The mip-mapping calculations are made by CPUs, but modern graphic processorscan be selected for this task and are way faster.

• Non-Manifold meshes essentially define geometry which cannot exist in the real world.This kind of geometry is not suitable for several types of operations,especially those where knowing the volume (inside/outside) of the object is important(refraction, fluids, booleans, or 3D printing, to name a few).A non-manifold mesh is a mesh in which the structure ofa non-overlapped surface (based on its connected faces) will not determinethe inside or the outside of a volume based on its normals, defininga single surface for both sides, but ended with flipped normals.When working with non-closed volumes, a non-manifold mesh will alwaysdetermine at least one discontinuity in the normal directions, eitherby an inversion of a connected loop, or by an odd number of surfaces.A non-manifold mesh will always define an odd number of surfaces.

  • A perspective view is geometrically constructed by taking a scene in 3D and placing an observerat point O. The 2D perspective scene is built by placing a plane (e.g. a sheet of paper)where the 2D scene is to be drawn in front of point O, perpendicular to the viewing direction.For each point P in the 3D scene a PO line is drawn, passing by O and P.The intersection point S between this PO line and the plane is the perspective projectionof that point. By projecting all points P of the scene you get a perspective view.
  • 正交
