When true, the geometry is expected to be closed so PerInstanceColorAppearance.renderState has backface culling enabled. Default value - false

When true, the fragment shader flips the surface normal as needed to ensure that the normal faces the viewer to avoid dark spots. This is useful when both sides of a geometry should be shaded like WallGeometry. Default value - !options.closed

When true, flat shading is used in the fragment shader, which means lighting is not taking into account. Default value - false

Optional GLSL fragment shader source to override the default fragment shader.

Optional render state to override the default render state.

When true, the geometry is expected to appear translucent so PerInstanceColorAppearance.renderState has alpha blending enabled. Default value - true
