Module attr 

Vertex and instance attribute types.

This module defines the DataType trait (implemented for all primitive numeric types and their fixed-size arrays), the ATTRInfo / ATTRName descriptors, and a set of concrete attribute containers:

• Pos3DATTR, Pos2DATTR — position
• ColATTR — colour (RGBA)
• UVMATTR — UV / texture coordinates
• NrmATTR — normal vectors
• IndATTR — index buffer
• Rot3DATTR, Rot2DATTR — rotation (quaternion / angle)
• Scale3DATTR, Scale2DATTR — scale
• CustomATTR — user-defined arbitrary attribute data

Structs

ATTRInfo

Describes a single vertex or instance attribute: name, GL type, byte size, element count.

ColATTR

CustomATTR

User-defined vertex or instance attribute with arbitrary byte data.

IndATTR

NrmATTR

Pos2DATTR

Pos3DATTR

Rot2DATTR

Rot3DATTR

Scale2DATTR

Scale3DATTR

UVMATTR

Enums

ATTRName

Discriminated name for a vertex or instance attribute.

Traits

DataType

Trait for types that can be used as vertex or instance attribute data.
