Classes
class	CameraNavigationControl
	Implements base::CameraControl, rotates the camera around itself and allows completely free camera movement. More...
class	CameraShowcaseControl
	Implements base::CameraControl, rotates the camera around its parent node. The camera movement is bounded to the rail from its parent to its current location. More...
class	CompositionStage
	Defines rendering stage that combines two other renderings either by putting them next to each other or through row-wise interleaving. More...
class	CuttingPlanesStage
	Renders cutting planes of volume geometries in the scene. More...
class	DRRStage
	Renders digital radiograph reconstructs of volume geometries in the scene. More...
class	DVRStage
	Performs direct volume renderings of the volume geometries in the scene. More...
class	MaskRenderingStage
	Renders 3D masks. More...
class	MeshColorCodingStage
	Implements a simple interface for mapping frame coordinates to base::Mesh objects. More...
class	MIPStage
	Renders maximum intensity projections of volume geometries in the scene. More...
class	OccludedRenderingStage
	Renders geometry that is actually depth-occluded. The occluded geometry is rendered with reduced opacity on-top of the geometry that it is occluded by. More...
class	OrthogonalControl
	Controls orthogonal projection matrices, that induce box-shaped visible volume, and base::Camera objects that use such projections. More...
class	ParallaxStage
	Produces stereoscopic renderings. More...
class	PerspectiveControl
	Controls projection matrices that induce frustum-shaped visible volume. More...
class	TransparentRenderingStage
	Implements rendering stage that renders transparent meshes. More...
class	VolumeRenderingStage
	Defines abstract base class for rendering stages that render volume geometries in the scene. More...

Typedef Documentation

OpaqueRenderingStage

typedef base::MeshRenderingStage< base::Renderable::VideoResourcesOrder< base::MeshRenderingMixin::DEFAULT_ROLE_MATERIAL > > LibCarna::presets::OpaqueRenderingStage

Implements rendering stage that renders opaque meshes.

The OpaqueRenderingStage constructor takes a geometry type parameter:

    opaque = new presets::OpaqueRenderingStage( GEOMETRY_TYPE_OPAQUE );
    renderer->appendStage( opaque );

The concept of geometry types is explained here.

Note

In the rendering process this stage will usually be inserted before such stages that render transparent geometry, like TransparentRenderingStage and VolumeRenderingStage.

The following example code configures the scene s.t. it produces the rendering presented further below:

    base::ManagedMeshBase& boxMesh = base::MeshFactory< base::PVertex >::createBox( 40, 40, 40 );
    base::Material& redMaterial   = base::Material::create( "unshaded" );
    base::Material& greenMaterial = base::Material::create( "unshaded" );
    redMaterial  .setParameter( "color", base::math::Vector4f( 1, 0, 0, 1 ) );
    greenMaterial.setParameter( "color", base::math::Vector4f( 0, 1, 0, 1 ) );
 
    base::Geometry* const box1 = new base::Geometry( GEOMETRY_TYPE_OPAQUE );
    base::Geometry* const box2 = new base::Geometry( GEOMETRY_TYPE_OPAQUE );
 
    box1->putFeature( presets::OpaqueRenderingStage::DEFAULT_ROLE_MESH, boxMesh );
    box2->putFeature( presets::OpaqueRenderingStage::DEFAULT_ROLE_MESH, boxMesh );
 
    box1->putFeature( presets::OpaqueRenderingStage::DEFAULT_ROLE_MATERIAL,   redMaterial );
    box2->putFeature( presets::OpaqueRenderingStage::DEFAULT_ROLE_MATERIAL, greenMaterial );
 
    boxMesh.release();
    redMaterial.release();
    greenMaterial.release();
 
    scene->root->attachChild( box1 );
    scene->root->attachChild( box2 );
 
    box1->localTransform = base::math::translation4f( -10, -10, -40 );
    box2->localTransform = base::math::translation4f( +10, +10, +40 );

The concept of materials, meshes and other geometry feature is explained here.
