# 6DoF - Flat AR Capabilities

# Method Definition

6DoF - Planar AR capabilities, providing basic AR capabilities, providing 6 degrees of freedom of positioning for rotation and translation.

IncludingV1andV2are two algorithms for different scenarios, and the two flat AR capabilities have advantages and disadvantages. The user can determine the type of interface to call according to the applicable scenario and product requirements, as follows:

1. V1 plane interface, suitable for users in a plane scene, such as desktop, ground, pan-plane scene, place virtual objects, do not provide real world distance. When the user places an object, the phone camera tilts down to the target plane and clicks on it, which is supported by a wide range of models.
2. V2 plane interface, provide real physical distance AR positioning function, provide plane recognition function, the user click on the plane to place the function of virtual objects, with limited support models.

# Capacity expansion

On theV2plane, a variety of extensions can be configured to enable, such as:

1. Marker recognition ability, that is, the recognition of multiple different recognition targets in plane space.
2. The ability to mask reality, that is, the ability to block the interaction between virtual objects and the real world.

For more details on the effects and switch configuration, see Flat AR capability expansion .

# How to open V1 or V2

The initial implementation is determined by VKSession configuration version.

const session = wx.createVKSession({
  track: {
    plane: {
        mode: 1
    },
  },
  version: 'v2' // 在满足设备条件时开启，否则会使用 v1
  // version: "v1" 强制开启v1
})

For the complete VKSession configuration, see VKSession configuration reference .

V2 Flat Demo

V2 plane + virtual and real occlusion demo

# Program Examples

1. You can view the sample code on the V1 plane page.
2. You can view the sample code on the V2 plane page.
3. Can be in V2 plane + virtual and real occlusion The page looks at the sample code and experiences it in **Interface - VisionKit Vision Capabilities - horizontal AR-v2-false mask]] in [[TAG-1END]] in the Weixin Mini Program example.
