RenderTexture Class

Initializes a new instance of the RenderTexture class

Determines if the content can be edited.

Category for this content.

Returns the localized display name of the child slot name

Display name for this content.

Obsolete. Do not use. You should use DocumentOwner instead.

If this render content is associated with a document in any way, the document will be returned. This includes copies of render contents that were attached to a document when the copy was made. Otherwise returns null.

If this render content is owned by a document, the document will be returned. This is the same as getting the document the render content is attached to. Otherwise returns null.

Obsolete. Do not use. You should use DocumentOwner instead.

Rhino.Render.Fields FieldDictionary which provides access to setting and retrieving field values.

If the content is file based, this function can be overridden to deal with setting/getting the filename. Corresponds to IRhRdkFileBasedContent in the C++ SDK

A string array of full paths to files used by the content that may be embedded in .3dm files and library files (.rmtl, .renv, .rtex). The default implementation returns an empty string list. Override this to return the file name or file names used by your content. This is typically used by textures that reference files containing the texture imagery.

Return First child of this content or null if none.

Group ID of the content

Gets or sets the render content's 'hidden' state. This feature only works for top-level render contents because it hides the entire hierarchy. It is normally used for 'implementation detail' render contents. For expert use only. Hidden render contents are never shown in the UI, with the exception of the Object (or Layer) Material Properties UI which always shows whatever is assigned to the object (or layer). In the Object (or Layer) Material Properties UI, if the user drops down the list, hidden render contents are not listed. Hidden render contents, being part of the document content list, will be listed by any scripts or other code that iterates over the document render content list. It is recommended that you set IsHidden once when you create your render content and leave it on to prevent flicker or slow performance.

Instance identifier for this content.

Checks if render content is default instance.

Contents can be created as 'auto-delete' by certain commands such as 'Picture'. These contents are automatically hidden from the user when the associated Rhino object is deleted. They are later deleted when the document is saved.

Set this property to true prior to adding content to the document to lock the content browser editing UI methods. Setting this to true will keep the browser from allowing things like deleting, renaming or changing content. This is useful for custom child content that you want to be editable but persistent. Setting this after adding content to the document will cause an exception to be thrown.

Gets the transformation that can be applied to the UVW vector to convert it from normalized texture space into locally mapped space (ie - with repeat, offset and rotation applied.)

Instance 'raw' name for this content.

Return First sibling of this content or null if none.

Notes for this content.

Returns the top content in this parent/child chain.

Override to provide details on the actual pixel sizes of this texture in UVW directions return null if the texture should not be treated as a bitmap.

Gets the proxy type of the render content

Render hash for the content hierarchy. It iterates over children and includes a caching mechanism which means the hash value can be retrieved quickly if it hasn't changed. The cache is invalidated when Changed() is called. You can override the CalculateRenderHash(UInt64) method to provide a custom hash value.

Render hash for texture excluding local mapping.

Render hash for texture excluding local mapping and linear workflow.

Tags for this content.

Returns true if this content has no parent, false if it is the child of another content.

Returns the top content in this parent/child chain.

Description for your content type. i.e., "Procedural checker pattern"

Type identifier for this content

Name for your content type. i.e., "My .net Texture"

Add a new automatic user interface section, Field values which include prompts will be automatically added to this section.

Add a new .NET control to an content expandable tab section, the height of the createExpanded tabs client area will be the initial height of the specified control.

Begins a change or batch of changes. It may also make a copy of the content state allowing EndChange to send an event with the old and new contents. Calls to this method are counted; you must call EndChange() once for every call to BeginChange(). Note: If Changed() was called between the calls to BeginChange() and EndChange(), the last call to EndChange() may cause the ContentChanged event to be sent.

Automatic Dynamic Field support. Dynamic fields are typically created in the constructor of RenderContent and they are therefore created automatically whenever the content is created. However, some advanced users require the fields to be created in response to some user action which occurs much later. This creates the problem that the fields do not exist by default and therefore cannot be loaded when the document is loaded. These methods are provided to solve that problem by making it possible to automatically create the dynamic fields on loading if they don't already exist. Dynamic fields that have this auto-create-on-load behavior are referred to as automatic dynamic fields. Dynamic fields that do not require the advanced automatic feature can still be created by using these methods (recommended), or they can be created manually (legacy usage). You must call this before creating any dynamic fields. Calls to this method are counted; you must call EndCreateDynamicFields() once for every call to BeginCreateDynamicFields().

Use bindings to automatically wire parameters to fields

Use bindings to automatically wire parameters to fields

Override this method to calculate the render hash of the state that affects how the content is rendered. Does not include children or perform any caching. Render hash values are now automatically cached by the content framework and you do not have to worry about caching. You also do not have to worry about iterating into children. This method is now only called internally by the framework, use the RenderHash property to get the current hash value.

(Inherited from RenderContent.)

Gets the amount property for the texture in the specified child slot.

A "child slot" is the specific "slot" that a child (usually a texture) occupies. This is generally the "use" of the child - in other words, the thing the child operates on. Some examples are "color", "transparency".

Gets the on-ness property for the texture in the specified child slot.

Modify your content so that it is converted from meters into the units of the unit system. No need to call the base class when you override this, and no need to recurse into children.

Create a dynamic field with an initial value and min and max limits.

Constructs a texture evaluator. This is an independent lightweight object capable of evaluating texture color throughout uvw space. May be called from within a rendering shade pipeline.

Dispose

This method allows a render content hierarchy to be edited using a modal (AKA 'pop-up') editor. If the original render content is in a document, it will remain there, and the edited one will be 'free-floating'. Therefore it is the caller's responsibility to do any replacement in the document if required. The returned new content will be owned by the caller.

Ends a change or batch of changes. Calls to this method are counted; you must call this method once for every call to BeginChange(RenderContentChangeContexts). Note: If BeginChange(RenderContentChangeContexts) was called with ChangeContexts.UI, ChangeContexts.Program, ChangeContexts.Drop or ChangeContexts.UI.Tree and Changed() was called between the calls to BeginChange(RenderContentChangeContexts) and EndChange(), the last call to EndChange() will raise the ContentChanged event.

You must call this after creating dynamic fields. Calls to this method are counted; you must call BeginCreateDynamicFields() once for every call to EndCreateDynamicFields().

Determines whether the specified object is equal to the current object.

Finalizer

**** This method is for proxies and will be marked obsolete in the future **** The only place a single proxy can be displayed is in the New Content Control main thumbnail. All other attempts to use a single proxy in a UI require it to be replaced with the corresponding multi proxy. Single proxies override this to find the corresponding multi proxy.

Extra requirements are a way of specifying extra functionality on parameters in the automatic UI. Override this function to specify additional functionality for automatic UI sections or the texture summary. See IAutoUIExtraRequirements.h in the C++ RDK SDK for string definitions for the parameter names. Call the base class from your override if you do not support the extra requirement parameter. Please do not call this function. It is only retained for backward compatibility. You should instead call GetExtraRequirementParameter().

Serves as the default hash function.

Get offset value across UVW space. If the projection type is WCS or other type specified in model units, then this is the offset in meters.

Query the content instance for the value of a given named parameter. If you do not support this parameter, call the base class.

Get repeat value across UVW space. If the projection type is WCS or other type specified in model units, then this is the repeat across 1 meter of the model.

Gets the Type of the current instance.

This allows a content to have more than one UI for the same content type.

Override this method to restrict the type of acceptable child content. The default implementation of this method returns true if the factory kind is 'texture'.

Return true if the texture is HDR capable. When creating a custom RenderTexture implementation that is HDR capable set the appropriate property on the CustomRenderContentAttribute decorator on that clas.

Query if the texture is image based. When creating a custom RenderTexture implementation of an image-based texture set the appropriate property on the CustomRenderContentAttribute decorator on that class. Do not override this function

Return true if the texture color data is linear. NOTE: this function is marked as virtual, but the correct way to make a custom RenderTexture linear is by setting the correct property for the CustomRenderContentAttribute decorator on the class.

Return true if the texture is a normalmap. When creating a custom RenderTexture implementation of a normal map set the appropriate property on the CustomRenderContentAttribute decorator on that clas.

Query whether or not the content or any of its ancestors is a reference content.

This method is deprecated and no longer called. For more information see CalculateRenderHash(UInt64)

Create a copy of the render content. All content is the same, except for the instance Id.

Create an 'instance' of the content hierarchy and group the new hierarchy with this hierarchy. If the instance is subsequently attached to the same document, the state of all members of the group will be kept synchronized. With the exception of the instance ids, all state is exactly preserved in the new instance hierarchy. \note The grouping will have no effect until the new instance is attached to the same document.

Implement to transfer data from another content to this content during creation.

Creates a shallow copy of the current Object.

ModifyRenderContentStyles

Constructs a new basic texture from a SimulatedTexture.

Constructs a new basic texture from a Bitmap.

Constructs a new basic texture from a SimulatedTexture.

Gets the PreviewSceneServer of the content

Override to provide UI sections to display in the editor.

Override this method to prompt user for information necessary to create a new content object. For example, if you are created a textured material you may prompt the user for a bitmap file name prior to creating the textured material.

Override this function to supplement the standard copying behavour for your RenderContent.

Call this method to open the content in the relevant thumbnail editor and select it for editing by the user. The content must be in the document or the call will fail.

Call this method to open the content in the a modal version of the editor. The content must be in the document or the call will fail.

A "child slot" is the specific "slot" that a child (usually a texture) occupies. This is generally the "use" of the child - in other words, the thing the child operates on. Some examples are "color", "transparency".

Get the texture dimensions for the RenderTexture.

As RenderHash, but allows you to specify flags and exclude specific parameters.

This method is deprecated in favor of the one that takes CrcRenderHashFlags.

As RenderHash, but allows you to specify flags and exclude specific parameters. Use this version of the function to calculate a render hash when you have the linear workflow information and you are not running on the main thread. Access to LinearWorkflow data requires document access. CrcRenderHashFlags.ExcludeLinearWorkflow must be specified.

Save texture as image

Saves content to a file - RMTL, RENV or RTEX.

Set another content as a child of this content. This content may or may not be attached to a document. If this content already has a child with the specified child slot name, that child will be deleted. If this content is not attached to a document, the child will be added without sending any events. If this content is attached to a document, the necessary events will be sent to update the UI. Note: Do not call this method to add children in your constructor. If you want to add default children, you should override Initialize() and add them there.

By default, RenderHash recurses into children when computing the render hash. However, some applications may require children to be excluded from the render hash calculation. Call this method to enable or disable recursing into children. see RenderHash

Set instance name for this content

Set offset value across UVW space. If the projection type is WCS or other type specified in model units, then this is the offset in meters.

Set the named parameter value for this content instance. If you do not support this parameter, call the base class.

Set repeat value across UVW space. If the projection type is WCS or other type specified in model units, then this is the repeat across 1 meter of the model.

Remove this content and all its children from any instance groups they may be a member of. If any content in the same document is left alone in the group, that content is also ungrouped. Records undo and sends events OnContentChanged and OnContentGroupIdChanged. \note This method is designed to be called from a content UI and is intended for RDK internal use but may be used as an expert user override.

Returns a string that represents the current object.

Remove this content from any instance group it may be a member of. Does not record undo but does send the OnContentGroupIdChanged event.
