Material and texture of primitives

[tana]

Some fields to specify material and texture of primitive shapes.

• Things to think...
  • Multiple types of materials (PBR, diffuse-specular-ambient, or custom shader?)
  • Multiple texture targets (color, normal map etc.)

It requires careful design.

[tana]

One idea:

• Specify material type (shading model?) using tag or material field
• Use fields to specify parameters of particular material type (e.g. diffuse)

Should create ARGB type in IValue?

Alpha is specified by separate alpha field, rather than ARGB.
