Detailed Description

SceneView class represents a dynamic real time 3D view onto the scene.

The SLSceneView class has a pointer to an active camera that is used to generate the 3D view into a window of the clients GUI system. OpenGL ES3.0 or newer is used the default renderer for framebuffer rendering. Alternatively the sceneview can be rendered with a software ray tracing or path tracing renderer. All mouse, touch, keyboard, resize and paint events of the GUI system are handled in this class by the appropriate event handler methods. If your app need special event handling you can subclass this class and override the virtual function. If the scene contains itself no camera node the sceneview provides its own camera object.

Constructor & Destructor Documentation

◆ SLSceneView()

SLSceneView::SLSceneView	(	SLScene *	s,
		int	dpi,
		SLInputManager &	inputManager
	)

SLSceneView default constructor.

The default constructor adds the this pointer to the sceneView vector in SLScene. If an in between element in the vector is zero (from previous sceneviews) it will be replaced. The sceneviews _index is the index in the sceneview vector. It never changes throughout the life of a sceneview.

◆ draw3DCT()

◆ draw3DGL()

SLbool SLSceneView::draw3DGL ( SLfloat elapsedTimeMS )

Draws the 3D scene with OpenGL.

This is the main routine for updating and drawing the 3D scene for one frame. The following steps are processed:

Render shadow maps: Renders all shadow maps for lights in SLLight::renderShadowMap
Updates the camera: If the active camera has an animation it gets updated first in SLCamera::camUpdate
Clear all buffers: The color and depth buffer are cleared in this step. If the projection is the Oculus stereo projection also the framebuffer target is bound.
Set viewport: Depending on the projection we set the camera projection and the view for the center or left eye.
Render background: If no skybox is used the background is rendered. This can be the camera image if the camera is turned on.
Set projection and view: Sets the camera projection matrix
Frustum culling: During the cull traversal all materials that are seen in the view frustum get collected in _visibleMaterials. All nodes with their meshes get collected in SLMaterial::_nodesVisible3D. These materials and nodes get drawn in draw3DGLAll.
Draw skybox: The skybox is draw as first object with frozen depth buffer. The skybox is always around the active camera.
Draw all visible nodes: By calling the SLSceneView::draw3DGL all visible nodes of all visible materials get drawn sorted by material and transparency. If a stereo projection is set, the scene gets drawn a second time for the right eye.
Draw right eye for stereo projections

◆ draw3DGLAll()

void SLSceneView::draw3DGLAll ( )

SLSceneView::draw3DGLAll renders by material sorted to avoid expensive material switches on the GPU. During the cull traversal all materials that are seen in the view frustum get collected in _visibleMaterials. All nodes with their meshes get collected in SLMaterial::_nodesVisible3D.
The 3D rendering has then the following steps: 1) Draw nodes with meshes with opaque materials and all helper lines sorted by material
2) Draw remaining opaque nodes (SLCameras, needs redesign)
3) Draw nodes with meshes with blended materials sorted by material and sorted back to front
4) Draw remaining blended nodes (SLText, needs redesign)
5) Draw helpers in overlay mode (not depth buffered)
6) Draw visualization lines of animation curves

◆ draw3DGLLines()

void SLSceneView::draw3DGLLines ( SLVNode & nodes )

SLSceneView::draw3DGLLines draws the AABB from the passed node vector directly with their world coordinates after the view transform. The lines must be drawn without blending. Colors: Red : AABB of nodes with meshes Pink : AABB of nodes without meshes (only child nodes) Yellow: AABB of selected node

◆ draw3DGLLinesOverlay()

void SLSceneView::draw3DGLLinesOverlay ( SLVNode & nodes )

SLSceneView::draw3DGLLinesOverlay draws the nodes axis and skeleton joints as overlay

◆ draw3DGLNodes()

void SLSceneView::draw3DGLNodes	(	SLVNode &	nodes,
		SLbool	alphaBlended,
		SLbool	depthSorted
	)

SLSceneView::draw3DGLNodes draws the nodes meshes from the passed node vector directly with their world transform after the view transform.

◆ draw3DPT()
