Detailed Description

Scene graph. Contains functionality for selecting nodes, setting properties specific to adaptive cutaways.

Member Function Documentation

void Scene::clear

(

)

Destroys the subgraph of the root and all its attached renderables.

SceneNode * Scene::createSceneNode

(

)

Returns a new scene node of this scene

void Scene::deselect

(

Renderable *

renderable)

Marks an object as not selected

void Scene::deselectAll

(

)

Deselects all objects

void Scene::enableGizmo

(

bool

enabled)

Enables or disables gizmo editing in the scene.

Camera * Scene::getCamera

(

)

Returns the active camera in the scene.

bool Scene::getDirectionalConstraint

(

)

Renderable * Scene::getFirstSelected

(

)

Returns an arbitrary selected object

float Scene::getGhostDistance

(

)

Returns the value for the ghost lines effect.

Gizmo * Scene::getGizmo

(

)

Returns the active gizmo in the scene.

float Scene::getGlobalAngle

(

)

Returns the angle of the cutaway for objects that don't have a local angle set.

int Scene::getLineType

(

)

Returns the selected line type. See setLineType.

SceneNode * Scene::getRoot

(

)

Returns the root of the scene graph

void Scene::renderAll

(

Shader *

shader)

Draws all renderables in the graph with the selected shader.

void Scene::renderInterface

(

Shader *

shader)

Render the gizmo.

void Scene::renderSelected

(

Shader *

shader)

Draws all selected renderables in the graph with the selected shader.

void Scene::renderSelectedThatCanCut

(

Shader *

shader)

Draws all selected renderables in the graph that have the canCut property enabled with the selected shader.

void Scene::renderUnselected

(

Shader *

shader)

Draws all unselected renderables in the graph with the selected shader.

void Scene::renderUnselectedThatCanBeCut

(

Shader *

shader)

Draws all unselected renderables in the graph that have the canBeCut property enabled with the selected shader.

void Scene::renderUnselectedThatCannotBeCut

(

Shader *

shader)

Draws all unselected renderables in the graph that have the canBeCut property disabled with the selected shader.

void Scene::resetGlobalAngle

(

)

Resets the angle of the cutaway for objects that don't have a local angle set to 30°.

void Scene::select

(

Renderable *

renderable)

Marks an object as selected

rset_iter_t Scene::selectionBegin

(

)

Returns an iterator to the beginning of the list of selected objects

rset_iter_t Scene::selectionEnd

(

)

void Scene::setCamera

(

Camera *

camera)

Set the active camera in the scene.

void Scene::setDirectionalConstraint

(

bool

c)

Enables or disables the directional constraint effect.

void Scene::setEdgeCompression

(

bool

c)

Enables or disables the edge compression effect.

void Scene::setGhostDistance

(

float

dist)

Sets a value for the ghost lines effect. 0 = lines close to cutaway objects, 4 = maximal distance to cutaway objects

void Scene::setGlobalAngle

(

float

angle)

Sets the angle of the cutaway for objects that don't have a local angle set.

void Scene::setLineType

(

int

lineType)

Sets the line type. LINES_ON for fully visible outlines of occluding objects. LINES_GHOST for ghost lines that are only invisible in front of the cutaway objects. LINES_OFF for no lines on occluding objects.

void Scene::setSelectionCanBeCut

(

bool

c)

void Scene::update

(

double

frameLength)

Called by the application every frame to update logic of the scene graph

void Scene::updateTransforms

(

const glm::mat4 &

viewMatrix)

Propagtes transformation matrices through the scene graph
