Functionality

The cool thing about these Nodes is that they can be jointly querried. We can find neighbouring nodes way faster by not using the actual data!

import geomapi.tools as tl
tl.select_nodes_k_nearest_neighbors(pcdNode,[meshNode,imgNode,bimNodes],k=1) #selects the k nearest neighbors of a point cloud node from a list of nodes

([<geomapi.nodes.meshnode.MeshNode at 0x1d6ea7c2170>], DoubleVector[2.09905]) # the meshNode is the closest Node 2m away!

GEOMAPI divides functions into three layers.

  1. Utilities: Base functions for point clouds and images that support the Node system

import geomapi.utils as ut
from geomapi.utils import geometryutils as gmu

  1. Nodes: Node specific functions such as projecting rays from an ImageNode in 3D, mutations, surface sampling, etc.

imgNode=ImageNode(xmlPath='../tests/testfiles/img/road.xml', path='../tests/testfiles/img/101_0367_0007.JPG') 
imgNode.create_rays(imagePoints=[[0,0],[0,1],[1,0],[1,1]],depths=25) #creates rays from image points

  1. Tools: Functions that combine nodes for distance calculations, intersections, analyses, etc.

import geomapi.tools as tl
import geomapi.tools.progresstools as pgt
pgt.project_pcd_to_rgbd_images (pointClouds, imgNodes, depth_max=15)

Look at the Function Tutorial notebooks to learn more about how to use the different functions.
