Copies all the params from a the given source_param_object to this param object. Does not replace any currently existing params with the same name.

Parameters:

sourceParamObject

param object to copy params from.

Creates a DrawElement for this Element. Note that unlike Shape.createDrawElements and Transform.createDrawElements this one will create more than one element for the same material.

Parameters:

	pack	pack used to manage created DrawElement.
	material	material to use for DrawElement. If you pass null it will use the material on this Element. This allows you to easily setup the default (just draw as is) by passing null or setup a shadow pass by passing in a shadow material.

Returns:

!o3d.DrawElement.The created draw element.

Creates a Param with the given name and type on the ParamObject. Will fail if a param with the same name already exists.

Parameters:

	paramName	The name of the Param to be created.
	paramTypeName	The type of Param to create. Valid types are 'o3d.ParamBoolean' 'o3d.ParamBoundingBox' 'o3d.ParamDrawContext' 'o3d.ParamDrawList' 'o3d.ParamEffect' 'o3d.ParamFloat' 'o3d.ParamFloat2' 'o3d.ParamFloat3' 'o3d.ParamFloat4' 'o3d.ParamFunction' 'o3d.ParamInteger' 'o3d.ParamMaterial' 'o3d.ParamMatrix4' 'o3d.ParamParamArray' 'o3d.ParamRenderSurface' 'o3d.ParamRenderDepthStencilSurface' 'o3d.ParamSampler' 'o3d.ParamSkin' 'o3d.ParamSteamBank' 'o3d.ParamState' 'o3d.ParamString' 'o3d.ParamTexture' 'o3d.ParamTransform' 'o3d.ProjectionParamMatrix4' 'o3d.ProjectionInverseParamMatrix4' 'o3d.ProjectionTransposeParamMatrix4' 'o3d.ProjectionInverseTransposeParamMatrix4' 'o3d.ViewParamMatrix4' 'o3d.ViewInverseParamMatrix4' 'o3d.ViewTransposeParamMatrix4' 'o3d.ViewInverseTransposeParamMatrix4' 'o3d.ViewProjectionParamMatrix4' 'o3d.ViewProjectionInverseParamMatrix4' 'o3d.ViewProjectionTransposeParamMatrix4' 'o3d.ViewProjectionInverseTransposeParamMatrix4' 'o3d.WorldParamMatrix4' 'o3d.WorldInverseParamMatrix4' 'o3d.WorldTransposeParamMatrix4' 'o3d.WorldInverseTransposeParamMatrix4' 'o3d.WorldViewParamMatrix4' 'o3d.WorldViewInverseParamMatrix4' 'o3d.WorldViewTransposeParamMatrix4' 'o3d.WorldViewInverseTransposeParamMatrix4' 'o3d.WorldViewProjectionParamMatrix4' 'o3d.WorldViewProjectionInverseParamMatrix4' 'o3d.WorldViewProjectionTransposeParamMatrix4' 'o3d.WorldViewProjectionInverseTransposeParamMatrix4'

Returns:

o3d.Param.The newly created Param or null on failure.

Computes the bounding box in same coordinate system as the specified POSITION stream.

Parameters:

positionStreamIndex

Index of POSITION stream.

Returns:

!o3d.BoundingBox.The boundingbox for this element in local space.

Searches by name for a Param defined in the object.

Parameters:

paramName

Name to search for.

Returns:

o3d.Param.The Param with the given name, or null otherwise.

Computes the intersection of a ray in the same coordinate system as the specified POSITION stream.

Parameters:

	positionStreamIndex	Index of POSITION stream.
	cull	which side of the triangles to ignore.
	start	position of start of ray in local space.
	end	position of end of ray. in local space.

Returns:

!o3d.RayIntersectionInfo.RayIntersectionInfo class. If valid() is false then something was wrong, Check client::GetLastError(). If intersected() is true then the ray intersected a something. position() is the exact point of intersection.

Takes the name of a class as an argument, and returns true if this object is either an instance of that class or derives from that class.

var t = pack.createObject('o3d.Transform');
t.isAClassName('o3d.Transform');    // true
t.isAClassName('o3d.ParamObject');  // true
t.isAClassName('o3d.Shape');        // false

Parameters:

className

Name of class to check for.

Returns:

boolean.true if this object is a or is derived from the given class name.

Removes a Param from a ParamObject. This function will fail if the param does not exist on this ParamObject or if the param is unremovable.

Parameters:

param

param to remove.

Returns:

boolean.True if the param was removed.

The BoundingBox for this element. If culling is on this bounding box will be tested against the view frustum of any draw context used to render this Element. Default = [[0, 0, 0], [0, 0, 0]].

The concrete class name for an object derived from ObjectBase. If you want to know if an object is of a certain type you should use objectBase.isAClassName

var t = pack.createObject('o3d.Transform');
t.className == 'o3d.Transform';  // true

Unique id of the object. This id will be unique, even across multiple O3D clients in the same page. This property is read-only.

The cull settings for this element. If true this Element will be culled by the bounding box above compared to the view frustum it is being rendered with. Default = false.

Gets all the DrawElements under this Element. Each access to this field gets the entire list so it is best to get it just once. For example:

var drawElements = element.drawElements;
for (var i = 0; i < drawElements.length; i++) {
  var drawElement = drawElements[i];
}

The Material for this element.

The object's name. Setting this has no meaning to O3D, but is useful for debugging and for the functions Client.getObjects, Pack.getObject, RenderNode.getRenderNodesByNameInTree and RenderNode.getTransformsByNameInTree which search for objects by name.

The current owner of this Draw Element. Pass in null to stop being owned. Note: Elements are referenced by the Pack they are created in and their owner. If the Element is removed from its Pack then setting the owner to null will free the Element. Or, visa versa, if you set the Element's owner to null then removing it from its Pack will free the Element.

Gets all the param on this param object. Each access to this field gets the entire list, so it is best to get it just once. For example:

var params = paramObject.params;
for (var i = 0; i < params.length; i++) {
  var param = params[i];
}

The priority for this element. Used to sort if this Element is drawn by a DrawPass that is set to sort by priority. Default = 0.

The z sort point for this element. If this Element is drawn by a DrawPass that is set to sort by z order this value will be multiplied by the worldViewProjection matrix to compute a z value to sort by. Default = [0, 0, 0].

The Material used by this Element.

The BoundingBox used by this Element for culling.

The point to sort by when rendering this Element in a z ordered DrawPass.

Whether or not to attempt to cull this element based on whether or not its bounding box is in the view frustum.
