A3DETessellationLevelOfDetail

enum A3DETessellationLevelOfDetail

Structure to specify the level of detail of the tessellation.

See:c:struct:~A3DRWParamsTessellationDataparameters. When a level is given, the Chord Height Ratio (A3DRWParamsTessellationData::m_dChordHeightRatio) and Wireframe Chord Angle (A3DRWParamsTessellationData::m_dAngleToleranceDeg) change to preset values for the selected level.

enumerator kA3DTessLODExtraLow

kA3DTessLODExtraLow

Extra Low level: when selected, these members are automatically defined with the following values:

• A3DRWParamsTessellationData::m_dChordHeightRatio= 50,
• A3DRWParamsTessellationData::m_dAngleToleranceDeg= 40.

enumerator kA3DTessLODLow

kA3DTessLODLow

Low level: when selected, these members are automatically defined with the following values:

• A3DRWParamsTessellationData::m_dChordHeightRatio= 600,
• A3DRWParamsTessellationData::m_dAngleToleranceDeg= 40.

enumerator kA3DTessLODMedium

kA3DTessLODMedium

Medium level: when selected, these members are automatically defined with the following values:

• A3DRWParamsTessellationData::m_dChordHeightRatio= 2000,
• A3DRWParamsTessellationData::m_dAngleToleranceDeg= 40.

enumerator kA3DTessLODHigh

kA3DTessLODHigh

High level: when selected, these members are automatically defined with the following values:

• A3DRWParamsTessellationData::m_dChordHeightRatio= 5000,
• A3DRWParamsTessellationData::m_dAngleToleranceDeg= 30.

enumerator kA3DTessLODExtraHigh

kA3DTessLODExtraHigh

Extra High level: when selected, these members are automatically defined with the following values:

• A3DRWParamsTessellationData::m_dChordHeightRatio= 10000,
• A3DRWParamsTessellationData::m_dAngleToleranceDeg= 20.

enumerator kA3DTessLODUserDefined

kA3DTessLODUserDefined

User Defined level: when selected, these members should be defined:

• A3DRWParamsTessellationData::m_dChordHeightRatioif:c:member:A3DRWParamsTessellationData::m_bUseHeightInsteadOfRatio <A3DRWParamsTessellationData.m_bUseHeightInsteadOfRatio>is set to false,
• A3DRWParamsTessellationData::m_dMaxChordHeightif:c:member:A3DRWParamsTessellationData::m_bUseHeightInsteadOfRatio <A3DRWParamsTessellationData.m_bUseHeightInsteadOfRatio>is set to true,
• A3DRWParamsTessellationData::m_dAngleToleranceDeg. Be very careful when using:c:member:A3DRWParamsTessellationData::m_dMaxChordHeight <A3DRWParamsTessellationData.m_dMaxChordHeight>because a too small value would generate a huge tessellation.
