Reader options
Readers can provide option that can be set using the -D/--define command line option. eg: -DVDB.downsampling_factor=0.5.
Values are parsed as doubles. For booleans, 0 means false, not 0 means true.
vdb-VDB.downsampling_factor: Control the level of downsampling when reading a volume, default is 0.1.occt-STEP.linear_deflection: Control the distance between a curve and the resulting tessellation, default is 0.1.occt-STEP.angular_deflection: Control the angle between two subsequent segments, default is 0.5.occt-STEP.relative_deflection: Control if the deflection values are relative to object size, default is false.occt-STEP.read_wire: Control if lines should be read, default is true.occt-IGES.linear_deflection: Control the distance between a curve and the resulting tessellation, default is 0.1.occt-IGES.angular_deflection: Control the angle between two subsequent segments, default is 0.5.occt-IGES.relative_deflection: Control if the deflection values are relative to object size, default is false.occt-IGES.read_wire: Control if lines should be read, default is true.occt-BREP.linear_deflection: Control the distance between a curve and the resulting tessellation, default is 0.1.occt-BREP.angular_deflection: Control the angle between two subsequent segments, default is 0.5.occt-BREP.relative_deflection: Control if the deflection values are relative to object size, default is false.occt-BREP.read_wire: Control if lines should be read, default is true.occt-XBF.linear_deflection: Control the distance between a curve and the resulting tessellation, default is 0.1.occt-XBF.angular_deflection: Control the angle between two subsequent segments, default is 0.5.occt-XBF.relative_deflection: Control if the deflection values are relative to object size, default is false.occt-XBF.read_wire: Control if lines should be read, default is true.
Format details
QuakeMDL
- Models texture are loaded with a simple PBR lighting (diffuse color only, no specular, index of refraction set to 1.0).
- Selecting
skinis not supported. - Loading
groupskinis not supported. - Animation frames are split based on their names, eg:
stand1,stand2,stand3,run1,run2,run3.
