The objective of this step is to create a dense geometric surface representation of the scene. The output of this node is a high-poly mesh, which can be used for any further processing in Houdini.

## Parameters

## Main

Cook

Start the cooking process for this step.

Manual Mode

This toggle controls if the node should automatically recook if any dependencies have changed.

Use Log

This toggle controls if the status of the current node should be printed to the console. This is useful for getting a quick overview of the progress.

## Meshing

Max Input Points

Max input points loaded from depth map images.

Max Points

Max points at the end of the depth maps fusion.

Max Points per Voxel

Max points per voxel.

Min Step

The step used to load depth values from depth maps is computed from maxInputPts. Here we define the minimal value for this step, so on small datasets we will not spend too much time at the beginning loading all depth values.

Vertex Colors

Whether to colorize output dense point cloud and mesh.

Partitioning

Enable Partitioning.

Repartition

Enable Repartitioning.

Angle Factor

AngleFactor.

Sim Factor

Sim Factor.

pixSizeMarginInitCoef

pixSizeMarginInitCoef.

pixSizeMarginFinalCoef

pixSizeMarginFinalCoef.

voteMarginFactor

voteMarginFactor.

contributeMarginFactor

contributeMarginFactor.

simGaussianSizeInit

simGaussianSizeInit.

simGaussianSize

simGaussianSize.

minAngleThreshold

minAngleThreshold.

Refine Fuse

Refine depth map fusion with the new pixels size defined by angle and similarity scores.

Estimate Space From SfM

Estimate the 3d space from the SfM.

Min Observations For SfM Space Estimation

Minimum number of observations for SfM space estimation.

Min Observations Angle For SfM Space Estimation

Minimum angle between two observations for SfM space estimation.

Add Landmarks To The Dense Point Cloud

Add SfM Landmarks to the dense point cloud.

## Mesh Filter

Filter Large Triangles Factor

Remove all large triangles. We consider a triangle as large if one edge is bigger than N times the average edge length. Put zero to disable it.

Keep Only the Largest Mesh

Keep only the largest connected triangles group.

Num of Iterations

Number of smoothing iterations.

Lambda

Lambda.

## Environment

Environment

The environment used for launching the AliceVision utilities commandline. Note that this is a python expression and should be modified only through “Edit Expression”.

## Outputs

AV Depth Map

This plugs into AV Texturing, and holds the generated mesh.

Pointcloud

This is the pointcloud generated by the meshing step.
