Re: [FreeWRL-develop] VRML1 - do we want to support this still?

Ian;

What the "VRML1 to VRML97 translator" does is, it puts some special nodes in the VRML97 scene graph.

So, it does run the same way, but there's just a bunch of non-standard nodes.

VRML1_AsciiText
VRML1_Cone
VRML1_Cube
VRML1_Cylinder
VRML1_IndexedFaceSet
VRML1_IndexedLineSet
VRML1_PointSet
VRML1_Sphere
VRML1_Coordinate3
VRML1_FontStyle
VRML1_Info
VRML1_Material
VRML1_MaterialBinding
VRML1_Normal
VRML1_NormalBinding
VRML1_Texture2
VRML1_Texture2Transform
VRML1_TextureCoordinate2
VRML1_ShapeHints
VRML1_MatrixTransform
VRML1_Rotation
VRML1_Scale
VRML1_Transform
VRML1_Translation
VRML1_Separator
VRML1_Switch
VRML1_WWWAnchor
VRML1_LOD
VRML1_OrthographicCamera
VRML1_PerspectiveCamera
VRML1_DirectionalLight
VRML1_PointLight
VRML1_SpotLight
VRML1_WWWInline

You can write (well, could, shader code not written) a VRML97-style VRML/X3D file, and include the above nodes, and it would work.

The translator took the VRML1 and put it into a VRML97 syntax, and called most of these nodes.

Some of the nodes map directly into VRML97 nodes, some really don't.
