These constants are used for describing the contents of a vertex buffer.
| Constant | Description |
|---|---|
| vertex_type_float1 | Single floating point attribute |
| vertex_type_float2 | Attribute comprised of a two floating point values |
| vertex_type_float3 | Attribute comprised of a three floating point values |
| vertex_type_float4 | Attribute comprised of a four floating point values |
| vertex_type_colour | Attribute comprised of four unsigned byte values |
| vertex_type_ubyte4 | Attribute comprised of four unsigned byte values |
The following constants are used to describe the usage of the vertex attributes.

| vertex_usage_normal | Normal attribute (nx,ny,nz) |
| vertex_usage_textcoord | Texture coordinates (u,v) |
| vertex_usage_blendweight | Blendweight of the input matrix (used for skeletal animation) |
| vertex_usage_blendindices | Indices of the matrices to use (used for skeletal animation) |
| vertex_usage_depth | Depth attribute |
| vertex_usage_tangent | Tangent attribute |
| vertex_usage_binormal | Binormal attribute |
| vertex_usage_fog | Fog attribute |
| vertex_usage_sample | Sample index |
