Member Typedef Documentation

typedef VertexAttribsInfo<Sphere> oglplus::shapes::Sphere::VertexAttribs

Vertex attribute information for this shape builder.

Sphere provides build functions for the following named vertex attributes:

• "Position" the vertex positions (Positions)
• "Normal" the vertex normal vectors (Normals)
• "Tangent" the vertex tangent vector (Tangents)
• "Bitangents" the vertex bi-tangent vector (Bitangents)
• "TexCoord" the ST texture coordinates (TexCoordinates)
