Fields

veSource :: Int

The source vertex buffer, as bound to an index using VertexBufferBinding

veOffset :: Int

The offset in the buffer that this element starts at

veType :: VertexElementType

The type of element

veSemantic :: VertexElementSemantic

The meaning of the element

veIndex :: Int

Index of the item, only applicable for some elements like texture coords

Instances

Eq VertexElement

Ord VertexElement

Show VertexElement

getTypeSize :: VertexElementType -> Int

Utility method for helping to calculate offsets

getTypeCount :: VertexElementType -> Int

Utility method which returns the count of values in a given type

multiplyTypeCount :: VertexElementType -> Int -> VertexElementType

Simple converter function which will turn a single-value type into a multi-value type based on a parameter.

getBaseType :: VertexElementType -> VertexElementType

Simple converter function which will convert a type into its single-value equivalent to make switches on type easier.
