Detailed Description

This abstract node type is the base type for all node types which specify texture coordinates.

It adds a new geometric property node type to those specified in 11 Rendering component.

Texture coordinate nodes comes in two flavours, types that generate texture coordinates and nodes that specify the texture coordinates explicitly. There are two groups of functions, one for each of the types. When a user wants to use a function he should first check if it is supported by calling the supportsExplicitTexCoords() and supportsTexGen() functions.

Member Function Documentation

◆ defaultXMLContainerField()

virtual string H3D::X3DTextureCoordinateNode::defaultXMLContainerField ( )

inlinevirtual

Returns the default xml containerField attribute value.

For this node it is "texCoord".

Reimplemented from H3D::Node.

◆ disableVBOForActiveTexture()

void X3DTextureCoordinateNode::disableVBOForActiveTexture ( )

static

Function that corresponds to the static version of the function renderVertexBufferObjectForActiveTexture.

Disables state for active texture.

References disableVBOForTexture(), and H3D::X3DTextureNode::getActiveTexture().

Referenced by H3D::Cylinder::render(), H3D::FullscreenRectangle::render(), and H3D::Sphere::render().

◆ disableVBOForTexture()

void X3DTextureCoordinateNode::disableVBOForTexture ( X3DTextureNode * t )

static

Function that corresponds to the static version of the function renderVertexBufferObjectForTexture.

Disables state for given texture.

References H3D::MultiTexture::texture.

◆ getTexCoord()

virtual Vec4f H3D::X3DTextureCoordinateNode::getTexCoord	(	int	,
		unsigned int
	)

inlinevirtual

Gets texture coordinate of the given index and texture unit.

This function is only valid if supporteGetTexCoord returns true. TextureCoordinateGenerator e.g. does not support this function.

Reimplemented in H3D::TextureCoordinate, H3D::TextureCoordinate4D, H3D::TextureCoordinate3D, and H3D::MultiTextureCoordinate.

References Vec4f().

Referenced by H3D::MultiTextureCoordinate::getTexCoord(), and H3D::IndexedFaceSet::AutoTangent::getTexCoord().

◆ nrAvailableTexCoords()

virtual unsigned int H3D::X3DTextureCoordinateNode::nrAvailableTexCoords ( )

inlinevirtual

Returns the number of texture coordinates this node can render.

-1 means that the node is a texture coordinate generator in which case nr available coords has no meaning.

Reimplemented in H3D::TextureCoordinate4D, H3D::TextureCoordinate3D, H3D::TextureCoordinate, and H3D::MultiTextureCoordinate.

Referenced by H3D::MultiTextureCoordinate::nrAvailableTexCoords(), H3D::IndexedTriangleFanSet::render(), H3D::IndexedTriangleSet::render(), H3D::IndexedTriangleStripSet::render(), H3D::TriangleFanSet::render(), H3D::TriangleSet::render(), and H3D::TriangleStripSet::render().

◆ renderVertexBufferObjectForActiveTexture()

void X3DTextureCoordinateNode::renderVertexBufferObjectForActiveTexture	(	GLint	size,
		GLenum	type,
		GLsizei	stride,
		const GLvoid *	pointer
	)

static

Render the vertex buffer object for all texture units used by the texture in X3DTextureNode::getActiveTexture.

The arguments to this function are the same arguments as to glTexCoordPointer when using vertex buffer objects since this function is basically a wrapper around that function to handle the case of the texture being a MultiTexture.

References H3D::X3DTextureNode::getActiveTexture(), and renderVertexBufferObjectForTexture().

Referenced by H3D::ElevationGrid::render(), and H3D::X3DComposedGeometryNode::renderTexCoordVertexBufferObject().

void X3DTextureCoordinateNode::renderVertexBufferObjectForTexture	(	GLint	size,
		GLenum	type,
		GLsizei	stride,
		const GLvoid *	pointer,
		X3DTextureNode *	t
	)

static

Render the vertex buffer object for all texture units used by the given texture.

The other arguments to this function are the same arguments as to glTexCoordPointer when using vertex buffer objects since this function is basically a wrapper around that function to handle the case of the texture being a MultiTexture.
