This page provides a list of 3D rendering software, the dedicated engines used for rendering computer-generated imagery.This is not the same as 3D modeling software, which involves the creation of 3D models, for which the software listed below can produce realistically rendered visualisations.
A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture.They may be stored in common image file formats, referenced by 3D model formats or material definitions, and assembled into resource bundles.
Polygon Cruncher simplifies meshes and retains most details even while reducing polygons by as much as 95%. [2] Texture information, vertex colors, and specified normals are taken into account during optimization, as well as many others settings. For example, it is possible to define a symmetry axis in order to produce symmetrical low ...
A polygon mesh of a dolphin In 3D computer graphics , polygonal modeling is an approach for modeling objects by representing or approximating their surfaces using polygon meshes . Polygonal modeling is well suited to scanline rendering and is therefore the method of choice for real-time computer graphics .
The vast majority of 3D models today are built as textured polygonal models, because they are flexible, because computers can render them so quickly. However, polygons are planar and can only approximate curved surfaces using many polygons. Curve modeling – Surfaces are defined by curves, which are influenced by weighted control points. The ...
For example, Super Mario 64 would be considered low poly today, but was considered a stunning achievement when it was released in 1996. Similarly, in 2018, using hundreds of polygons on a leaf in the background of a scene would be considered high poly, but using that many polygons on the main character would be considered low poly.
An aggregation process combines all geometry and materials in a scene into one single object. Impostor. An imposter model maps all geometric details as textures and can be used if a model will be viewed from a distance and a certain direction. Occlusion mesh
Typically the geometry provides a normal and tangent. The tangent is part of the tangent plane and can be transformed simply with the linear part of the matrix (the upper 3x3). However, the normal needs to be transformed by the inverse transpose. Most applications will want bitangent to match the transformed geometry (and associated UVs).
