introduced a multitude of advanced mechanisms for supporting dynamics (animations) and 3D interactions with appropriate events and update mechanisms. Implementation strategies for X3DOM are explained in. described the X3DOM architecture in detail and compares it with various other approaches of integrating interactive 3D graphics with web browsers. Also developers benefit because synchronization problems between DOM content and plugin-based manipulations are avoided and of course also because developers do not need to focus on the peculiarities of just one plugin. Such a direct integration not only provides advantages for the users, namely that no plugin needs to be installed. The mapping of live DOM elements to a X3D scene model is very similar to the integration of interactive 2D vector graphics via SVG. X3DOM 2 was developed to integrate X3D in web applications directly. HTML5 references X3D for declarative 3D content but does not define the actual integration. Often, it is advantageous that also a memory-efficient binary encoding of X3D data is provided. In addition, X3D files may also be encoded in XML and thus easily mixed with other content that is available in XML. Thus, it provides a number of new nodes and capabilities. The development of X3D was triggered by progress in graphics hardware, in particular improved programming capabilities and multitexturing. Thus, VRML files need only minor adaptation to be used as X3D files. It is largely backwards-compatible with VRML.

X3D and WebGL X3D (extensible 3D), like VRML, is an open ISO standard defined by the W3 consortium and thus it is independent of any specific platform. Thus, trainees easily became lost in the 3D environments or were confronted with an overwhelming number of options. In addition, 3D interaction and navigation was often very difficult.

However, the low bandwidth in the 1990s and the requirement to install a VRML browser at the client side hampered widespread use. presented VRML-based prototypes for vascular surgery and neurosurgery. John provides an overview categorizing systems in general tools for medical education, educational tools for diagnosis and procedure training as well as collaboration support. VRML was also widely used for developing medical education systems.
With nodes that enable collision detection, e.g., to detect whether a surgical instrument touches an anatomical structure.Īn essential aspect for creating feature-rich medical education applications is the combination of Java and VRML. With manipulators that may control clipping planes or other widgets, and With sensors that observe certain properties and may trigger a reaction, In addition to the geometry, also the behavior is represented in nodes of the scene graph, e.g., Finally, stenciling is disabled, the OpenGL clipping plane is applied, and the clipped object is drawn with color and depth enabled. This draws the color and depth values of the cap into the framebuffer only where the stencil values equal 1.
The depth buffer is cleared, color buffer writes are enabled, and the polygon representing the clipping plane is now drawn using whatever material properties are desired, with the stencil function set to GL_EQUAL and the reference value set to 1. The stencil operation is then set to decrement the stencil value where the depth test passes, and the model is drawn with glCullFace(GL_FRONT).Īt this point, the stencil buffer is 1 wherever the clipping plane is enclosed by the front-facing and back-facing surfaces of the object. The stencil operation is set to increment the stencil value where the depth test passes, and the model is drawn with glCullFace(GL_BACK). The capping polygon is rendered into the depth buffer, and then depth buffer writes are disabled. The stencil buffer, color buffer, and depth buffer are cleared, and color buffer writes are disabled. Object surface polygons must have their vertices ordered so that they face away from the interior for face culling purposes. If some care is taken when modeling the object, solids that have a depth complexity greater than 2 (concave or shelled objects) and less than the maximum value of the stencil buffer can be rendered. A capping polygon is embedded in the clipping plane and the stencil buffer is used to trim the polygon to the interior of the solid. The stencil buffer provides an easy method for adding a “cap” to objects that are intersected by the clipping plane. OpenGL's application-defined clipping planes (sometimes called model clip planes) allow an application to clip the scene by a plane. When working with solid objects it is often useful to clip the object against a plane and observe the cross section.
