Description

Base class for vertex attribute. Describes what kind of data will be present in the attribute. This base class is necessary to have a type independent way to update the GPU meshes.

Constructor & Destructor Documentation

BaseVertexAttribute()

BaseVertexAttribute

(

const nap::rtti::TypeInfo &

elementType

)

Constructor

Parameters

elementType

the vertex buffer element type

Member Function Documentation

getCapacity()

virtual size_t getCapacity ( ) const

pure virtual

Returns

The internally allocated memory size.

Implemented in VertexAttribute< ELEMENTTYPE >.

getCount()

virtual int getCount ( ) const

pure virtual

Returns

Should return amount of element in the buffer.

Implemented in VertexAttribute< ELEMENTTYPE >.

getElementType()

const nap::rtti::TypeInfo& getElementType

(

)

const

Returns

element data type (vec3 etc.)

getFormat()

virtual VkFormat getFormat ( ) const

pure virtual

Returns

Should return GL type of the attribute. This is used during construction of the vertex attributes on the GPU.

Implemented in VertexAttribute< ELEMENTTYPE >.

getRawData()

virtual void* getRawData ( )

pure virtual

Returns

Should return type-less data for the vertex attribute buffer.

Implemented in VertexAttribute< ELEMENTTYPE >, and VertexAttribute< glm::vec3 >.

reserve()

virtual void reserve ( size_t  numElements )

pure virtual

Reserves CPU memory for the buffer.

Implemented in VertexAttribute< ELEMENTTYPE >, and VertexAttribute< glm::vec3 >.
