|
Copy constructor using CopyOp to manage deep vs shallow copy. |
|
|
|
Texture is a pure virtual base class, apply must be overriden. Implements osg::StateAttribute. Implemented in osg::Texture1D, osg::Texture2D, osg::Texture3D, osg::TextureCubeMap, and osg::TextureRectangle. |
|
Helper method. Creates the texture, but doesn't set or use a texture binding. Note: Don't call this method directly unless you're implementing a subload callback. |
|
Helper method. Subloads images into the texture, but doesn't set or use a texture binding. Note: Don't call this method directly unless you're implementing a subload callback. |
|
Helper method. Sets texture paramters. Reimplemented in osg::TextureRectangle. |
|
Returns true if the texture objects for all the required graphics contexts are loaded. |
|
Return the name of the attribute's class type. Reimplemented from osg::StateAttribute. Reimplemented in osgText::Font::GlyphTexture. |
|
Clone an attribute, with Object* return type. Must be defined by derived classes. Implements osg::StateAttribute. |
|
Clone the type of an attribute, with Object* return type. Must be defined by derived classes. Implements osg::StateAttribute. |
|
Returns -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs. |
|
Calls apply(state) to compile the texture. Reimplemented from osg::StateAttribute. |
|
Implemented in osg::Texture1D, osg::Texture2D, osg::Texture3D, osg::TextureCubeMap, and osg::TextureRectangle. |
|
|
|
|
|
Forces a recompile on next apply() of associated OpenGL texture objects. |
|
Force a reset on next apply() of associated OpenGL texture parameters. |
|
|
|
|
|
|
|
|
|
Gets the border color. |
|
|
|
Gets whether to use client storage for the texture. |
|
|
|
Gets the extension for the specified context. Creates the Extensions object for that context if it doesn't exist. Returns NULL if the Extensions object for the context doesn't exist and the createIfNotInitalized flag is false. Reimplemented in osg::Texture3D, and osg::TextureCubeMap. |
|
Gets the texture filter mode. |
|
Gets the const texture image for specified face. Implemented in osg::Texture1D, osg::Texture2D, osg::Texture3D, osg::TextureCubeMap, and osg::TextureRectangle. |
|
Gets the texture image for the specified face. Implemented in osg::Texture1D, osg::Texture2D, osg::Texture3D, osg::TextureCubeMap, and osg::TextureRectangle. |
|
Gets the internal texture format. |
|
Gets the internal texture format mode. |
|
Gets the maximum anisotropy value. |
|
Get the minimum number of display lists to retain in the deleted display list cache. |
|
Gets the number of images that can be assigned to this Texture. Implemented in osg::Texture1D, osg::Texture2D, osg::Texture3D, osg::TextureCubeMap, and osg::TextureRectangle. |
|
|
|
|
|
|
|
Returns a pointer to the texture object for the current context. |
|
Gets the dirty flag for the current contextID. |
|
Return the Type identifier of the attribute's class type. Implements osg::StateAttribute. |
|
Gets whether or not apply() unreferences image data. |
|
Gets the hardware mipmap generation hint. |
|
Gets the texture wrap mode. |
|
|
|
|
|
|
|
Return true if StateAttribute is a type which controls texturing and needs to be issued w.r.t to specific texture unit. Reimplemented from osg::StateAttribute. |
|
Return the name of the attribute's library. Reimplemented from osg::StateAttribute. |
|
If State is non-zero, this function releases OpenGL objects for the specified graphics context. Otherwise, releases OpenGL objexts for all graphics contexts. Reimplemented from osg::StateAttribute. |
|
Sets the border color. Only used when wrap mode is CLAMP_TO_BORDER. |
|
Sets the border width. |
|
Sets whether to use client storage for the texture, if supported by the graphics system. Note: If enabled, and the graphics system supports it, the osg::Image(s) associated with this texture cannot be deleted, so the UnRefImageDataAfterApply flag would be ignored. |
|
Overrides Extensions objects across graphics contexts. Typically used to ensure the same lowest common denominator of extensions on sustems with different graphics pipes. Reimplemented in osg::Texture3D, and osg::TextureCubeMap. |
|
Sets the texture filter mode. |
|
Sets the texture image for the specified face. Implemented in osg::Texture1D, osg::Texture2D, osg::Texture3D, osg::TextureCubeMap, and osg::TextureRectangle. |
|
Sets the internal texture format. Implicitly sets the internalFormatMode to USE_USER_DEFINED_FORMAT. |
|
Sets the internal texture format mode. Note: If the texture format is USE_IMAGE_DATA_FORMAT, USE_ARB_COMPRESSION, or USE_S3TC_COMPRESSION, the internal format mode is set automatically and will overwrite the previous _internalFormat. |
|
Sets the maximum anisotropy value, default value is 1.0 for no anisotropic filtering. If hardware does not support anisotropic filtering, use normal filtering (equivilant to a max anisotropy value of 1.0. Valid range is 1.0f upwards. The maximum value depends on the graphics system. |
|
Set the minimum number of texture objects to retain in the deleted display list cache. |
|
Sets the TEXTURE_COMPARE_FAIL_VALUE_ARB texture parameter. See http://oss.sgi.com/projects/ogl-sample/registry/ARB/shadow_ambient.txt. |
|
Sets shadow texture comparison function. |
|
Sets GL_TEXTURE_COMPARE_MODE_ARB to GL_COMPARE_R_TO_TEXTURE_ARB See http://oss.sgi.com/projects/ogl-sample/registry/ARB/shadow.txt. |
|
Sets shadow texture mode after comparison. |
|
Sets whether or not the apply() function will unreference the image data. If enabled, and the image data is only referened by this Texture, apply() will delete the image data. |
|
Sets the hardware mipmap generation hint. If enabled, it will only be used if supported in the graphics system. |
|
Sets the texture wrap mode. |
|
Takes the active texture objects from the Texture and places them in the specified TextureObjectListMap. |
