Types ¶
type View ¶
type View struct {
// width of lines for shape rendering, in normalized units
LineWidth float32
// projection matrix for converting 3D to 2D -- resulting X, Y coordinates are used from Vector3
Prjn math32.Matrix4
// the root Group node of the virtual world
World *eve.Group
// the SVG rendering canvas for visualizing in 2D
Scene *svg.SVG
// the root Group node in the Scene under which the world is rendered
Root *svg.Group
// library of shapes for bodies -- name matches Body.Vis
Library map[string]*svg.Group
}
View connects a Virtual World with a 2D SVG Scene to visualize the world
func (*View) AddFromLibrary ¶
AddFromLibrary adds shape from library to given group
func (*View) ConfigBodyShape ¶
ConfigBodyShape configures a shape for a body with current values
func (*View) ConfigView ¶
ConfigView configures the view node to properly display world node
func (*View) InitLibShape ¶
InitLibShape initializes Scene library with basic shape for given body
func (*View) InitLibrary ¶
func (vw *View) InitLibrary()
InitLibrary initializes Scene library with basic shapes based on bodies in the virtual world. More complex visualizations can be configured after this.
func (*View) InitLibraryBody ¶
InitLibraryBody initializes Scene library with basic shapes based on bodies in the virtual world. More complex visualizations can be configured after this.
func (*View) NewInLibrary ¶
NewInLibrary adds a new item of given name in library
func (*View) ProjectXY ¶
func (vw *View) ProjectXY()
ProjectXY sets 2D projection to reflect 3D X,Y coords
func (*View) ProjectXZ ¶
func (vw *View) ProjectXZ()
ProjectXZ sets 2D projection to reflect 3D X,Z coords
func (*View) SyncNode ¶
SyncNode updates the view tree to match the world tree, using ConfigChildren to maximally preserve existing tree elements returns true if view tree was modified (elements added / removed etc)
func (*View) Transform2D ¶
Transform2D returns the full 2D transform matrix for a given position and quat rotation in 3D
func (*View) UpdateBodyView ¶
UpdateBodyView updates the display properties of given body name recurses the tree until this body name is found.
func (*View) UpdateBodyViewNode ¶
UpdateBodyViewNode updates the body view info for given name(s) Essential that both trees are already synchronized.
func (*View) UpdatePose ¶
func (vw *View) UpdatePose()
UpdatePose updates the view pose values only from world tree. Essential that both trees are already synchronized.
