What is the meaning of axis-aligned?

In geometry, an axis-aligned object (axis-parallel, axis-oriented) is an object in n-dimensional space whose shape is aligned with the coordinate axes of the space. Examples are axis-aligned rectangles (or hyperrectangles), the ones with edges parallel to the coordinate axes.

How do I change the mesh size in unity?

2 Answers

1. Open up a separate application (Blender, 3ds Max, Maya for 3d models) and create a mesh you want. This is probably the solution that you want.
2. Create a script that will change Mesh object in runtime.
3. Use one of third-party packages that bring 3d modelling capabilities to Unity, such as ProBuilder.

How does an axis aligned bounding box work?

Axis Aligned Bounding Box means the box itself is always on the same orientation. To update the AABB you will need to recreate it each time the model rotates, and move it if the models positions changes. The box will change shape and size depending on the rotation and the model you use.

Which is the minimum bounding box for a point set?

The axis-aligned minimum bounding box (or AABB) for a given point set is its minimum bounding box subject to the constraint that the edges of the box are parallel to the (Cartesian) coordinate axes.

Which is a better fit of a bounding box?

(b) However, if the triangle’s vertices are first transformed from object space to world space and then bounded, the fit of the bounding box can be much better. An axis-aligned bounding box (AABB) is simply a rectangular parallelepiped whose faces are each perpendicular to one of the basis vectors.

When to use an aligned bounding box in ray tracing?

Such bounding boxes arise frequently in spatial subdivision problems, such as in ray tracing or collision detection. One common way to specify such a box is to provide two points Pmin = [ xmin ymin zmin] and Pmax = [ xmax ymax zmax ], as shown in Figure 11.61.
