Inheritance diagram for SoSceneTexture2:
This node behaves exactly like SoTexture2 when it comes mapping the actual texture onto subsequent geometry. Please read the SoTexture2 documentation for more information about how textures are mapped onto shapes.

Texture mapping model, for deciding how to "merge" the texturemap with the object it is mapped unto.
|
|
Enumeration of wrapping strategies which can be used when the texturemap doesn't cover the full extent of the geometry. |
|
For deciding how the texture's alpha channel is handled. It's not possible to automatically detect this, since the texture is stored only on the graphics card's memory, and it'd be too slow to fetch the image to test the alpha channel like Coin does for regular textures. |
|
This static method returns the SoType object associated with objects of this class. Reimplemented from SoNode. |
|
Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and "downward" casting. Usage example:
For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on. For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups. Implements SoBase. |
|
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Reimplemented from SoNode. |
|
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns Reimplemented from SoFieldContainer. |
|
Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system. Reimplemented from SoNode. |
|
Notifies all auditors for this instance when changes are made. Reimplemented from SoNode. |
|
Action method for SoWriteAction. Writes out a node object, and any connected nodes, engines etc, if necessary. Reimplemented from SoNode. |
|
This function performs the typical operation of a node for any action. Reimplemented from SoNode. |
|
Action method for the SoGLRenderAction. This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method. Reimplemented from SoNode. |
|
Action method for SoCallbackAction. Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph. Reimplemented from SoNode. |
|
Action method for SoRayPickAction. Checks the ray specification of the action and tests for intersection with the data of the node. Nodes influencing relevant state variables for how picking is done also overrides this method. Reimplemented from SoNode. |
|
Wrapping strategy for the S coordinate when the texturemap is narrower than the object to map unto. Default value is SoSceneTexture2::REPEAT. |
|
Wrapping strategy for the T coordinate when the texturemap is shorter than the object to map unto. Default value is SoSceneTexture2::REPEAT. |
|
Texturemapping model for how the texturemap is "merged" with the polygon primitives it is applied to. Default value is SoSceneTexture2::MODULATE. |
|
Blend color. Used when SoSceneTexture2::model is SoSceneTexture2::BLEND. Default color value is [0, 0, 0], black, which means no contribution to the blending is made. |
|
The color the color buffer is cleared to before rendering the scene. Default value is (0.0f, 0.0f, 0.0f, 0.0f). |
|
The size of the texture. This node currently only supports power of two textures. If the size is not a power of two, the value will be rounded upwards to the next power of two. |
|
The scene graph that is rendered into the texture. |
|
The transparency function used. Default value is NONE. |
