Detailed Description

A list of vertex attributes.

Used by shaders and meshes. The attributes of a mesh determine what data it stores in its vertices. The attributes of a shader describe which attributes it reads as inputs.

Note

This class also stores additional information including the offsets of each attribute. These are computed automatically by the constructors taking lists. To compute these manually, call computeAttributeOffsets().

Constructor & Destructor Documentation

AttributeSet::AttributeSet

(

)

Constructs an empty attribute set.

AttributeSet::AttributeSet ( std::initializer_list< Attribute >  list )

explicit

Constructs an attribute set from an initializer list.

This constructor calls computeAttributeOffsets() to compute this object's metadata.

Parameters

list	Initializer list containing attributes to add to this set

AttributeSet::AttributeSet ( const std::vector< Attribute > &  list )

explicit

Constructs an attribute set from a vector of attributes.

This constructor calls computeAttributeOffsets() to compute this object's metadata.

Parameters

list	List of attributes to add to this set

Member Function Documentation

void AttributeSet::computeAttributeOffsets

(

)

Computes and fills in this attribute set's attribute offsets and vertex stride.

Member Data Documentation

std::vector<int> AttributeSet::attributeOffsets

Number of bytes from the beginning of a vertex for each attribute.

This is computed by computeAttributeOffsets().

std::vector<Attribute> AttributeSet::attributes

List of attribute definitions.

int AttributeSet::vertexStride = 0

Number of bytes between vertices.

This is computed by computeAttributeOffsets().
