Function Documentation

addUniverseLevel()

void addUniverseLevel	(	SLAssetManager *	am,
		SLScene *	s,
		SLNode *	parent,
		SLint	parentID,
		SLuint	currentLevel,
		SLuint	levels,
		SLuint	childCount,
		SLVMaterial &	materials,
		SLVMesh &	meshes,
		SLuint &	numNodes
	)

Adds another level to Jan's Universe scene.

appDemoLoadScene()

void appDemoLoadScene	(	SLAssetManager *	am,
		SLScene *	s,
		SLSceneView *	sv,
		SLSceneID	sceneID
	)

appDemoLoadScene builds a scene from source code.

Forward declaration of the scene definition function from AppDemoLoad.cpp.

appDemoLoadScene builds a scene from source code. Such a function must be passed as a void*-pointer to slCreateScene. It will be called from within slCreateSceneView as soon as the view is initialized. You could separate different scene by a different sceneID.
The purpose is to assemble a scene by creating scenegraph objects with nodes (SLNode) and meshes (SLMesh). See the scene with SID_Minimal for a minimal example of the different steps.

BuildFigureGroup()

SLNode * BuildFigureGroup	(	SLAssetManager *	am,
		SLScene *	s,
		SLMaterial *	mat,
		SLbool	withAnimation
	)

Build a hierarchical figurine with arms and legs.

createComplexFire()

SLNode * createComplexFire	(	SLAssetManager *	am,
		SLScene *	s,
		SLbool	withLight,
		SLGLTexture *	texFireCld,
		SLGLTexture *	texFireFlm,
		SLint	flipbookCols,
		SLint	flipbookRows,
		SLGLTexture *	texCircle,
		SLGLTexture *	texSmokeB,
		SLGLTexture *	texSmokeW
	)

Creates a complex fire group node.

createTorchFire()

SLNode * createTorchFire	(	SLAssetManager *	am,
		SLScene *	s,
		SLbool	withLight,
		SLGLTexture *	texFireCld,
		SLGLTexture *	texFireFlm,
		SLint	flipbookCols,
		SLint	flipbookRows
	)

generateUniverse()

void generateUniverse	(	SLAssetManager *	am,
		SLScene *	s,
		SLNode *	parent,
		SLint	parentID,
		SLuint	levels,
		SLuint	childCount,
		SLVMaterial &	materials,
		SLVMesh &	meshes
	)

Generates the Jan's Universe scene.

RotatingSphereGroup()

SLNode * RotatingSphereGroup	(	SLAssetManager *	am,
		SLScene *	s,
		SLint	depth,
		SLfloat	x,
		SLfloat	y,
		SLfloat	z,
		SLfloat	scale,
		SLuint	resolution,
		SLVMaterial &	mat
	)

Creates a recursive rotating sphere group used for performance test.

This performance benchmark is expensive in terms of world matrix updates because all sphere groups rotate. Therefore all children need to update their wm every frame.

Parameters

am	Pointer to the asset manager
s	Pointer to project scene aka asset manager
depth	Max. allowed recursion depth
x	Position in x direction
y	Position in y direction
z	Position in z direction
scale	Scale factor > 0 and < 1 for the children spheres
resolution	NO. of stack and slices of the spheres
mat	Reference to an vector of materials

Returns

Group node of spheres

SphereGroupRT()

SLNode * SphereGroupRT	(	SLAssetManager *	am,
		SLint	depth,
		SLfloat	x,
		SLfloat	y,
		SLfloat	z,
		SLfloat	scale,
		SLuint	resolution,
		SLMaterial *	matGlass,
		SLMaterial *	matRed
	)

Creates a recursive sphere group used for the ray tracing scenes.
