octree

Each octree node has either eight children or no children.

An octree is a tree data structure in which each internal node has exactly eight children.

"At the heart of the machine is a parallel computer with octree architecture.

Most of the rendering tools (see below) use an octree file as input.

Before a scene can be used, it must be compiled into an octree file ('.

One technique is to use a sparse voxel octree.

A quadtree is simply a 2D octree.

Each node in an octree subdivides the space it represents into eight octants.

It uses ray tracing to perform all lighting calculations, accelerated by the use of an octree data structure.

In addition, the octree datastructure permits smoothing of the underlying data, to help with antialiasing.

Each cube-shaped node in the octree represents a renderable volume, simply referred to as a cube.

In an MX octree, the subdivision point is implicitly the center of the space the node represents.

That is, all the nodes of the octree can be generated from the list of its leaf nodes.

Red Eclipse utilizes the Cube 2 engine, which uses a 6-directional heightfield (or octree) world model.

The name is formed from oct + tree, but note that it is normally written "octree" with only one "t".

It works by raycasting the geometry represented by voxels (instead of triangles) stored in an octree.

Functions for serialization and deserialization enable to efficiently encode the octree structure into a binary format.

The sequential traversal of the narrow band is optimal and storage efficiency is further improved over the octree level set.

Cube 2: Sauerbraten shares most of its design goals and philosophy with its predecessor, but using a new 6-directional heightfield (or octree) world model.

An octree in Red Eclipse is a cube that can be split into eight smaller cubes that can then be done the same to.

As soon as any kind of hierarchical sorting or clustering scheme is applied, then it becomes something else (one example being an octree, a subdivided cube).

These algorithms arrange all particles in a tree, a quadtree in the two-dimensional case and an octree in the three-dimensional case.

A prototype 3D video animation package for the Amiga Computer led to the incorporation of Octree Software in 1986.

In 1993 Octree Software moved from New York to California and became known as Caligari Corporation.

The bottom level of the octree consists of leaf nodes that accrue color data not represented in the tree; these nodes initially contain single bits.
