class WebSceneNode : public virtual Karana::Scene::GraphicalSceneNode#

GraphicalSceneNode implementation for WebScene.

See Scene layer for more discussion on the scene layer.

Subclassed by Karana::Scene::WebSceneCamera, Karana::Scene::WebScenePart

Public Functions

WebSceneNode(std::string_view name, const Karana::Core::ks_ptr<Karana::WebUI::Server> &server, const kc::ks_ptr<Scene> &scene)#

WebSceneNode constructor. The constructor is not meant to be called directly. Please use the create(…) method instead to create an instance.

Parameters:

  • name – - Name of the WebSceneNode

  • server – - Server to communicate with frontends

  • scene – - WebScene to add the node to.

virtual void setUnitQuaternion(const Karana::Math::UnitQuaternion &quaternion) override#

Set rotation of the node relative to its parent.

Parameters:

quaternion – - The relative rotation as a unit quaternion

virtual void setTranslation(const Karana::Math::Vec3 &translation) override#

Set position of the node relative to its parent.

Parameters:

translation – - The relative translation

virtual void setScale(double scale) override#

Set uniform of the node relative to its parent.

Parameters:

scale – - The relative uniform scale

virtual void setVisible(bool visible) override#

Set whether the object is visible.

Parameters:

visible – - The visibility flag

virtual void attachTo(const Karana::Core::ks_ptr<SceneNode> &parent, bool maintain_world_transform = false) override#

Attach to a parent node.

Parameters:

  • parent – - The parent node

  • maintain_world_transform – - If true, update the node’s relative transform so that its overall world transform doesn’t change after attaching it to the parent

virtual void detach(bool maintain_world_transform = false) override#

Detach the node from its parent.

Parameters:

maintain_world_transform – - If true, update the node’s relative transform so that its overall world transform doesn’t change after detaching

virtual void showAxes(float size = 1) override#

Show axes to visualize the node’s position and orientation.

Parameters:

size – - Lengths of the axes (zero to remove the axes)

virtual void trail(const Karana::Core::ks_ptr<GraphicalSceneNode> &relative_to = nullptr, const Color &color = Color::WHITE) override#

Display a trail tracking the node’s motion over time.

Parameters:

  • relative_to – - Another node to draw the trail relative to.

  • color – - The color of the Trail.

virtual void removeTrail() override#

Remove a trail previously created by calling trail.

Public Static Functions

static Karana::Core::ks_ptr<WebSceneNode> create(std::string_view name, const Karana::Core::ks_ptr<WebScene> &scene)#

Create a WebSceneNode.

Parameters:

  • name – - Name of the node.

  • scene – - The WebScene to add the node to.

Returns:

The created WebSceneNode.

Protected Functions

virtual void _ioHandleConn(Karana::WebUI::Connection &conn) const#

Handler for a new frontend connection.

Parameters:

conn – - Connection to the new frontend

Protected Attributes

Karana::Core::ks_ptr<Karana::WebUI::Server> _server#

Server to communicate with frontends.
