Simple Reduction pipeline

This example shows how to create a new QuadReductionPipeline and how to set basic parameters for reduction and material baking.

-- create a QuadReductionPipeline object
quadReductionPipeline = sgsdk_CreatePipeline "QuadReductionPipeline"

-- set DefaultTangentCalculatorType to Autodesk3dsMax (1)
bResult = sgsdk_SetSetting quadReductionPipeline "GlobalSettings/DefaultTangentCalculatorType" 1
defaultTangentCalculatorType = sgsdk_GetSetting quadReductionPipeline "GlobalSettings/DefaultTangentCalculatorType"
print ("DefaultTangentCalculatorType: " + defaultTangentCalculatorType as string + "\n")

-- set the triangle ratio to 50%
bResult = sgsdk_SetSetting quadReductionPipeline "QuadReductionProcessor/QuadReductionSettings/ReductionTargetPolygonRatio" 0.5
reductionTargetPolygonRatio = sgsdk_GetSetting quadReductionPipeline "QuadReductionProcessor/QuadReductionSettings/ReductionTargetPolygonRatio"
print ("ReductionTargetPolygonRatio: " + reductionTargetPolygonRatio as string + "\n")

-- set the reduction target to triangle ratio
bResult = sgsdk_SetSetting quadReductionPipeline "QuadReductionProcessor/QuadReductionSettings/ReductionTargetPolygonRatioEnabled" true
reductionTargetPolygonRatioEnabled = sgsdk_GetSetting quadReductionPipeline "QuadReductionProcessor/QuadReductionSettings/ReductionTargetPolygonRatioEnabled"
print ("ReductionTargetPolygonRatioEnabled: " + reductionTargetPolygonRatioEnabled as string + "\n")

-- disable triangle count reduction target
bResult = sgsdk_SetSetting quadReductionPipeline "QuadReductionProcessor/QuadReductionSettings/ReductionTargetPolygonCountEnabled" false
reductionTargetPolygonCountEnabled = sgsdk_GetSetting quadReductionPipeline "QuadReductionProcessor/QuadReductionSettings/ReductionTargetPolygonCountEnabled"
print ("ReductionTargetPolygonCountEnabled: " + reductionTargetPolygonCountEnabled as string + "\n")

-- disable max deviation reduction target
bResult = sgsdk_SetSetting quadReductionPipeline "QuadReductionProcessor/QuadReductionSettings/ReductionTargetMaxDeviationEnabled" false
reductionTargetMaxDeviationEnabled = sgsdk_GetSetting quadReductionPipeline "QuadReductionProcessor/QuadReductionSettings/ReductionTargetMaxDeviationEnabled"
print ("ReductionTargetMaxDeviationEnabled: " + reductionTargetMaxDeviationEnabled as string + "\n")

-- disable onscreensize reduction target
bResult = sgsdk_SetSetting quadReductionPipeline "QuadReductionProcessor/QuadReductionSettings/ReductionTargetOnScreenSizeEnabled" false
reductionTargetOnScreenSizeEnabled = sgsdk_GetSetting quadReductionPipeline "QuadReductionProcessor/QuadReductionSettings/ReductionTargetOnScreenSizeEnabled"
print ("ReductionTargetOnScreenSizeEnabled: " + reductionTargetOnScreenSizeEnabled as string + "\n")

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

-- save the generated Pipeline object to file for later use
bResult = sgsdk_SavePipeline quadReductionPipeline "D:/Pipelines/QuadReduction.json"

-- clear all pipelines
sgsdk_ClearPipelines()
