WebGL 3D Space

iv.space

3d Space, list of nodes, materials, textures and 3d properties.

iv.space(wnd,gl)

Constructor creates new 3d space object. Usually space created from iv.window.

wnd	3d window
gl	WebGL context.

root	Root 3d node
gl	WebGL context
window	3d window
view	default view
root	Root 3d node
materials	Array of materials
cfgTextures	true if textures are allowed
cfgDbl	double sided rendering
cfgKeepMeshData	&1 - keep faces, &2 - keep points
cfgDefMtl	Default material. If null, per node materials will be used.
cfgSelZOffset	If true, selected objects will have z offset
cfgRMode	Default render mode. 0 is idefault value.
stdLights	Array of lights. If set, this lights will override lights in scene.

.select(node,sel,keep)

Method selects node in 3d space.

node	Node to select.
sel	true to select node, false - deselect.
keep	Keep old selection. In false previous selection will be removed.

.selectRange(a,b)

Method selects range of nodes in 3d space. Method is used with tree-view control, when user selects nodes with shift key.

a	First node
b	Second node

Node which was firstly created in its parent object is first in the list. Same as in tree-view control. This method does not send notifications.

.getSelection()

Method return list of selected nodes. If selection is empty null will be returned.

Select None:

space.select(null,false,true);

.newMaterial(data)

Method creates new material

data	If string - this will be name of material. You should create material channels after that. If object - data for material properties. This data may include name, colors, blending, textures, etc. For description of material please see WebGL material.

.getMaterial(name)

This method searches material by name and returns it.

name	Name of material.

If material was found it will be returned. If such material was not found, null will be returned.

.invalidate(flags)

Method marks viewport as invalid and scheduled update for the next frame. This method invokes iv.window.invalidate

flags

[optional] may be undefined or bit combinations of:

iv.INV_VERSION	Update camera, increment current camera version. Version may be used by billboards in order to update position only when required.
iv.INV_STRUCTURE	Structure was changed. Used to update shadow maps.
iv.INV_MTLS	Flush shaders in materials. Same as view.space.invalidateMaterials()

Default is 0.

.invalidateMaterials()

Method removes all shaders from materials. Method may be used after some changes in scenes, for instance after chaning lights.

.render()

Used internally for rendering scene.

Rest methods are used internally.
