class | cMultiMesh |
This class is the root of basically every render-able object in CHAI3D. It defines a reference frame (position and rotation) and virtual methods for rendering, which are overloaded by useful subclasses.
This class also defines basic methods for maintaining a scene graph, and propagating rendering passes and reference frame changes through a hierarchy of cGenericObjects.
The most important methods to look at here are probably the virtual methods, which are listed last in CGenericObject.h. These methods will be called on each cGenericObject as operations propagate through the scene graph.
chai3d::cGenericObject::cGenericObject | ( | ) |
Constructor of cGenericObject.
|
virtual |
Destructor of cGenericObject.
Deletes all children starting from this point in the scene graph, so if you have objects that shouldn't be deleted, be sure to remove them from the scene graph before deleting their parents.
|
virtual |
This method enables or disables this object.
When an object is disabled, haptic and graphic rendering are no longer performed through the scenegraph and the object is simply ignored. Other operations however will still be active.
Enabling or disabling an object will not affect child objects, unless explicitly specified.
a_enabled | If true then object is enabled, false otherwise. |
a_affectChildren | If true, then children are updated too. |

This method render this object. Subclasses will generally override this method. This is called from renderSceneGraph, which subclasses generally do not need to override.
A word on OpenGL conventions:
CHAI3D does not re-initialize the OpenGL state at every rendering pass. The only OpenGL state variables that CHAI3D sets explicitly in a typical rendering pass are:
lighting is enabled (cWorld)
depth-testing is enabled (cWorld)
glColorMaterial is enabled and set to GL_AMBIENT_AND_DIFFUSE/GL_FRONT_AND_BACK (cWorld)
a perspective projection matrix is set up (cCamera)
This adherence to the defaults is nice because it lets an application change an important piece of state globally and not worry about it getting changed by CHAI3D objects.
It is expected that objects will "clean up after themselves" if they change any rendering state besides:
color (glColor)
material properties (glMaterial)
normals (glNormal)
For example, if my object changes the rendering color, I don't need to set it back before returning, but if my object turns on vertex buffering, I should turn it off before returning. Consequently if I care about the current color, I should set it up in my own render() function, because I shouldn't count on it being meaningful when my render() function is called.
Necessary exceptions to these conventions include:
cLight will change the lighting state for his assigned GL_LIGHT
cCamera sets up relevant transformation matrices

This method renders the scene graph starting at this object. This method is called for each object and optionally render the object itself, its reference frame and the collision and/or scenegraph trees.
The object itself is rendered by calling render(), which should be defined for each subclass that has a graphical representation. renderSceneGraph does not generally need to be over-ridden in subclasses.

If true, transparency is enabled... this turns alpha on when the mesh is rendered, and - if multipass transparency is enabled in the rendering camera - uses the camera's multiple rendering passes to approximate back-to-front sorting via culling.
|
protected |
Should culling be used when rendering triangles?
Note that this option only applies when multipass transparency is disabled or during the non-transparent rendering pass when multipass transparency is enabled...
Also note that currently only back-faces are culled during non-transparent rendering; you can't cull front-faces.
