Set the X3DPrototypeInstance this node is the the root node if applicaple. | |
virtual void | render () |
the render() function is used for the depth-first rendering traversal of the scene-graph. More... | |
virtual void | traverseSG (TraverseInfo &ti) |
traverseSG is called once per scenegraph loop on the scene in order to traverse the scenegraph. More... | |
virtual bool | lineIntersect (const Vec3f &from, const Vec3f &to, LineIntersectResult &result) |
Detect intersection between a line segment and the Node. More... | |
virtual void | closestPoint (const Vec3f &p, NodeIntersectResult &result) |

FreeImageLoader uses the FreeImage library to load the images.
Most image file types are supported including PNG, JPEG, GIF, BMP, TIFF and PSD
Examples:
|
inlinevirtual |
Load the image using the FreeImage library.
A new FreeImageImage is returned. NULL if not successfully loaded.
url | URL to the file to load. |
Implements H3D::H3DImageLoaderNode.
References H3DUtil::loadFreeImage().
|
inlinevirtual |
Load an image from an istream.
Does not need to be implemented for all image loaders
Reimplemented from H3D::H3DImageLoaderNode.
References H3DUtil::loadFreeImage().
