Detailed Description

Associates stream views (vertex buffer views and an index buffer view) with material data. A ModelLodAsset::Mesh can have many Streams but only one material id.

Member Function Documentation

◆ GetIndexBufferTyped()

template<class T >
AZStd::span< const T > AZ::RPI::ModelLodAsset::Mesh::GetIndexBufferTyped ( ) const

A helper method for returning this mesh's index buffer using a specific type for the elements.

Note
It's the caller's responsibility to choose the right type for the buffer.

◆ GetMaterialSlotId()

ModelMaterialSlot::StableId AZ::RPI::ModelLodAsset::Mesh::GetMaterialSlotId ( ) const

Returns the ID of the material slot used by this mesh. This maps into the ModelAsset's material slot list.

◆ GetSemanticBufferAssetView()

const BufferAssetView * AZ::RPI::ModelLodAsset::Mesh::GetSemanticBufferAssetView ( const AZ::Name &  semantic) const

A helper method for returning a specific buffer asset view. It will return nullptr if the semantic buffer is not found. For example, to get a position buffer for a mesh with AZ::Name("POSITION"). In perf loop, re-use AZ::Name instance.

◆ GetSemanticBufferTyped()

template<class T >
AZStd::span< const T > AZ::RPI::ModelLodAsset::Mesh::GetSemanticBufferTyped ( const AZ::Name &  semantic) const

A helper method for returning this mesh's buffer using a specific type for the elements. For example, to get a position buffer for a mesh with AZ::Name("POSITION") and T=float. In perf loop, re-use AZ::Name instance.

Note
It's the caller's responsibility to choose the right type for the buffer.
