[static] float QSSGModelHelpers:: getGlobalOpacity (const QSSGFrameData & frameData , QSSGNodeId model )

Returns Returns the global opacity for the model .

frameData

[static] float QSSGModelHelpers:: getGlobalOpacity (const QSSGFrameData & frameData , QSSGNodeId model , QSSGPrepContextId prepId )

Returns Returns the global opacity for the model in context of the prepId . By default the prep context argument is QSSGPrepContextId::Uninitialized which returns the model's original global opacity.

frameData

[static] QMatrix4x4 QSSGModelHelpers:: getGlobalTransform (const QSSGFrameData & frameData , QSSGNodeId model , QSSGPrepContextId prepId = {})

Returns Returns the global transform for the model in context of the prepId . By default the prep context argument is QSSGPrepContextId::Uninitialized which returns the model's original global transform.

[static] float QSSGModelHelpers:: getLocalOpacity (const QSSGFrameData & frameData , QSSGNodeId model )

Returns Returns the local opacity for the model .

frameData

[static] QMatrix4x4 QSSGModelHelpers:: getLocalTransform (const QSSGFrameData & frameData , QSSGNodeId model )

Returns Returns the local transform for the model .

frameData

[static] void QSSGModelHelpers:: setGlobalOpacity (const QSSGFrameData & frameData , QSSGRenderablesId renderablesId , QSSGNodeId model , float opacity )

Sets the global opacity for model in the context of the renderablesId .

frameData , opacity

[static] void QSSGModelHelpers:: setGlobalTransform (const QSSGFrameData & frameData , QSSGRenderablesId renderablesId , QSSGNodeId model , const QMatrix4x4 & transform )

Sets the global transform for model in the context of the renderablesId .

frameData , transform

[static] void QSSGModelHelpers:: setModelMaterials (const QSSGFrameData & frameData , QSSGRenderablesId renderablesId , QSSGNodeId model , QSSGModelHelpers::MaterialList materials )

设置 materials to be used on model .

注意： 就像 materials 在 model item, materials are applied in the same manner.

The sub-mesh uses a material from the materials list, corresponding to its index. If the number of materials is less than the sub-meshes, the last material in the list is used for subsequent sub-meshes.

frameData renderablesId

[static] void QSSGModelHelpers:: setModelMaterials (const QSSGFrameData & frameData , QSSGRenderablesId renderablesId , QSSGModelHelpers::MaterialList materials )

Convenience function to apply materials to all models in the renderablesId set.

frameData , renderablesId
