Detailed Description

Wraps the OpenGL function glDrawArrays().

See also http://www.opengl.org/sdk/docs/man/xhtml/glDrawArrays.xml for more information.

DrawElements, MultiDrawElements, DrawRangeElements, DrawArrays are used by Geometry to define a set of primitives to be rendered, see Geometry::drawCalls().

Member Function Documentation

virtual const char* vl::DrawArrays::className ( ) [inline, virtual]

Returns the name of the class.

Reimplemented from vl::DrawCall.

DrawArrays& vl::DrawArrays::operator= ( const DrawArrays & other ) [inline]

virtual ref<DrawCall> vl::DrawArrays::clone ( ) const [inline, virtual]

Implements vl::DrawCall.

virtual void vl::DrawArrays::deleteVBOs ( ) [inline, virtual]

Implements vl::DrawCall.

virtual void vl::DrawArrays::updateVBOs	(	bool	,
		bool
	)		`[inline, virtual]`

Implements vl::DrawCall.

virtual unsigned int vl::DrawArrays::handle ( ) const [inline, virtual]

Implements vl::DrawCall.

virtual void vl::DrawArrays::render ( bool ) const [inline, virtual]

Implements vl::DrawCall.

void vl::DrawArrays::setStart ( int start ) [inline]

sets the starting vertex for the rendering.

int vl::DrawArrays::start ( ) const [inline]

returns the starting vertex for the rendering.

void vl::DrawArrays::setCount ( int count ) [inline]

sets the number of vertices to be rendered.

int vl::DrawArrays::count ( ) const [inline]

returns the number of vertices to be rendered.

void vl::DrawArrays::setInstances ( int instances ) [inline]

Sets the number of instances for this set of primitives.

int vl::DrawArrays::instances ( ) const [inline, virtual]

Returns the number of instances for this set of primitives.

Reimplemented from vl::DrawCall.

TriangleIterator vl::DrawArrays::triangleIterator ( ) const [inline, virtual]

Returns a TriangleIterator used to iterate through the triangles of a DrawCall.

Basically the iterator tesselates in triangles any DrawCall of type: PT_TRIANGLES, PT_TRIANGLE_STRIP PT_TRIANGLE_FAN, PT_POLYGON, PT_QUADS, PT_QUAD_STRIP.

Implements vl::DrawCall.

IndexIterator vl::DrawArrays::indexIterator ( ) const [inline, virtual]

Returns a IndexIterator used to iterate through the virtual indices of a DrawCall.
