Simple Aggregation pipeline

This example shows how to create a new AggregationPipeline and how to set basic parameters for Aggregation as well as material baking.

// create a AggregationPipeline object
$aggregationPipeline = `SimplygonPipeline -c "AggregationPipeline"`;

// set DefaultTangentCalculatorType to OrthonormalRightHanded (0)
$bResult = `SimplygonPipeline -ss "GlobalSettings/DefaultTangentCalculatorType" -v 0 $aggregationPipeline`;
$defaultTangentCalculatorType = `SimplygonPipeline -gs "GlobalSettings/DefaultTangentCalculatorType" $aggregationPipeline`;
print ("DefaultTangentCalculatorType: " + $defaultTangentCalculatorType + "\n");

// merge geometries
$bResult = `SimplygonPipeline -ss "AggregationProcessor/AggregationSettings/MergeGeometries" -v true $aggregationPipeline`;
$mergeGeometries = `SimplygonPipeline -gs "AggregationProcessor/AggregationSettings/MergeGeometries" $aggregationPipeline`;
print ("MergeGeometries: " + $mergeGeometries + "\n");

// more settings can be set for the Aggregation pipeline,
// see Pipeline documentation and/or inspect the generated file
// that is saved out by this script!

// set bMaterialBake to true to enable material baking,
// if material baking is enabled Simplygon will generate
// a new material (with textures) shared by all the optimized meshes.
$bMaterialBake = true;
if($bMaterialBake == true)
{
    // enable material baking
    // mapping image is required for material baking
    $bResult = `SimplygonPipeline -ss "AggregationProcessor/MappingImageSettings/GenerateMappingImage" -v true $aggregationPipeline`;
    $generateMappingImage = `SimplygonPipeline -gs "AggregationProcessor/MappingImageSettings/GenerateMappingImage" $aggregationPipeline`;

    // in this case we want to generate texture coordinates (UVs)

    $normalCaster3 = `SimplygonPipeline -gs ("MaterialCaster/" + $casterIndex + "/NormalCasterSettings/MaterialChannel") $aggregationPipeline`;
