This function is not supported in earlier versions. |
Attaches a vertex attribute from a different Mesh onto this Mesh, for use when drawing. This can be used to share vertex attribute data between several different Meshes.
Function
Synopsis
Mesh:attachAttribute( name, mesh )
Arguments
string name
- The name of the vertex attribute to attach.
Mesh mesh
- The Mesh to get the vertex attribute from.
Returns
Nothing.
Notes
If a Mesh wasn't created with a custom vertex format, it will have 3 vertex attributes named VertexPosition
, VertexTexCoord
, and VertexColor
.
Custom named attributes can be accessed in a vertex shader by declaring them as attribute vec4 MyCustomAttribute;
at the top-level of the vertex shader code. The name must match what was specified in the vertex format and in the name
argument to Mesh:attachAttribute.
