Unit

X3DNodes

Declaration

type TMaterialNode = class(TAbstractOneSidedMaterialNode)

Description

Material determines how the geometry looks on the screen, by providing parameters to the lighting equations. This is the material responsible for the Phong lighting model.

It specifies how light affects one side of the surface.

Note: Whether the shape is visible from both sides depends on the geometry TAbstractGeometryNode.Solid field, and is independent of whether you use this node or TTwoSidedMaterialNode.

Public destructor Destroy; override;

This item has no description.

Public class function ForVRMLVersion(const Version: TX3DVersion): boolean; override;

This item has no description. Showing description inherited from TX3DNode.ForVRMLVersion.

Some nodes are present only in specific VRML/X3D version. This functions decides it.

For example some nodes can only work in VRML < 2.0, some others only in VRML >= 2.0. There are even some pairs of nodes: for example TConeNode_1 works with VRML < 2.0, TConeNode works with VRML >= 2.0.

NodesManager will use this.

Default implementation of this function returns always True. Generally, I don't try to set this too aggresively — in other words, for all cases when it's sensible, I allow nodes to be used in every VRML/X3D version, even when official specification doesn't. This means that when reading VRML 1.0 files actually a large part of VRML 2.0 is allowed too, and also while reading VRML 2.0 many constructs from VRML 1.0 (officially no longer present in VRML 2.0) are allowed too. I'm trying to support what I call a "sum of VRML 1.0 and 2.0".

In practice I only use this function when various VRML/X3D versions specify the same node name but

  • With different fields.

    For example Cone and Cylinder have slightly different fields, due to the fact that VRML 2.0 resigned from using TSFBitMask fields.

  • With different behavior.

    For example definitions of Sphere for VRML 1.0 and 2.0 are practically equal. However, the behavior from where to take texture and material info is different — in VRML 1.0 we take last Texture2, Material etc. nodes, while in VRML 2.0 we look in parent Shape's "appearance" field. So once again two different Sphere classes are needed.

Public function Opacity: Single; deprecated 'use MaterialInfo.Opacity';

Warning: this symbol is deprecated: use MaterialInfo.Opacity

Opacity of the material, just 1 - Transparency. Sometimes it is more intuitive to use this than Transparency. Use MaterialInfo.Opacity.

Source: scene/x3d/x3dnodes_standard_shape.inc (line 277).

Public function ShininessExp: Single;

ShininessExp is just 128 * FdShininess.Value, this is the "real" exponent indicated by shininess field value. Defined for your comfort — for any graphic library you will usually want to pass the "real" exponent given by this function, not just value of shininess field.

Source: scene/x3d/x3dnodes_standard_shape.inc (line 284).

Public function MaterialInfo: TMaterialInfo; override;

This item has no description. Showing description inherited from TAbstractMaterialNode.MaterialInfo.

Material information based on this node. It is automatically updated when properties of this material change. Do not free it yourself, it will be automatically freed when this node is freed.

Source: scene/x3d/x3dnodes_standard_shape.inc (line 286).

Public function PureEmissive: boolean; deprecated 'use TUnlitMaterialNode for unlit materials';

Warning: this symbol is deprecated: use TUnlitMaterialNode for unlit materials

Only the emissiveColor is not black (zero), which means that the material behaves like unlit.

This checks that ambient and diffuse and specular colors are all zero. It's an important information about the material sometimes.

It is similar to the NULL material situation (when "Appearance.material=NULL" case), but the color and transparency are still configurable (using FdEmissiveColor and FdTransparency fields).

This way of achieving "something like unlit material" has issues, see https://github.com/michaliskambi/x3d-tests/wiki/Why-is-UnlitMaterial-useful . For this reason, we recommend to use (and detect, for optimization) the TUnlitMaterialNode instead of this "special case of Phong material".

Source: scene/x3d/x3dnodes_standard_shape.inc (line 302).

Public procedure ForcePureEmissive; deprecated 'use TUnlitMaterialNode for unlit materials';

Warning: this symbol is deprecated: use TUnlitMaterialNode for unlit materials

Force the material pure emissive (see PureEmissive) by setting other colors to black.

Public procedure CreateNode; override;

Create node fields and events.

Public class function ClassX3DType: String; override;

This item has no description. Showing description inherited from TX3DNode.ClassX3DType.

Node type name in VRML/X3D, for this class. Normal VRML/X3D node classes should override this to return something non-empty, and then X3DType automatically will return the same value.

Empty for classes that don't have a hardcoded VRML/X3D node name, like a special TX3DUnknownNode. Such special classes should override then X3DType to return actual non-empty name there.

You usually should call X3DType. The only use of this method is that it works on classes (it's "class function"), without needing at actual instance.
