inviwo::MeshDrawerGL Class Reference

Inheritance diagram for inviwo::MeshDrawerGL:

Classes
class	DrawObject
	This class provides functionality for efficient, subsequent drawing of a mesh. The buffers of the mesh will be bound once this class is instantiated. More...

Public Types
enum class	DrawMode {   NotSpecified = 0 , Points , Lines , LineStrip ,   LineLoop , LinesAdjacency , LineStripAdjacency , Triangles ,   TriangleStrip , TriangleFan , TrianglesAdjacency , TriangleStripAdjacency ,   NumberOfDrawModes }

Public Member Functions
virtual void	draw () override
	draws the mesh using its mesh info. If index buffers are present, the mesh will be rendered with glDrawElements() using those index buffers and the associated draw modes. Otherwise, the entire mesh is rendered using glDrawArrays with the default draw mode returned by Mesh::getDefaultMeshInfo().
virtual void	draw (DrawMode drawMode)
	draws the mesh with the specified draw mode. If index buffers are present, the mesh will be rendered with glDrawElements() using those index buffers. Otherwise, the entire mesh is rendered using glDrawArrays.

Member Function Documentation

canDraw()

virtual bool inviwo::MeshDrawerGL::canDraw ( const Mesh * geom ) const

inlineoverrideprotectedvirtual

Determine if the renderer can render geometry.

Parameters

geom	The Geometry to draw

Returns

Return true if able to render the Geometry, otherwise false.

Implements inviwo::MeshDrawer.

create()

virtual MeshDrawer * inviwo::MeshDrawerGL::create ( const Mesh * geom ) const

inlineoverrideprotectedvirtual

Return a new object of the derived class.

Note

The MeshDrawer does not take ownership of the Geometry.

Parameters

geom	The geometry to render. This will always be of a type that canDraw return true for.

Returns

A new renderer.

Implements inviwo::MeshDrawer.

draw() [1/2]

virtual void inviwo::MeshDrawerGL::draw ( )

overridevirtual

draws the mesh using its mesh info. If index buffers are present, the mesh will be rendered with glDrawElements() using those index buffers and the associated draw modes. Otherwise, the entire mesh is rendered using glDrawArrays with the default draw mode returned by Mesh::getDefaultMeshInfo().

Mesh, Mesh::MeshInfo

Implements inviwo::MeshDrawer.

draw() [2/2]

virtual void inviwo::MeshDrawerGL::draw ( DrawMode drawMode )

virtual

draws the mesh with the specified draw mode. If index buffers are present, the mesh will be rendered with glDrawElements() using those index buffers. Otherwise, the entire mesh is rendered using glDrawArrays.

Mesh, DrawMode

Parameters

drawMode

draw mode used to render the mesh

getMesh()

virtual const Mesh * inviwo::MeshDrawerGL::getMesh ( ) const

inlineoverridevirtual

Get the geometry to render.

Returns

Implements inviwo::MeshDrawer.
