Detailed Description

The SoGLVBOElement class is used to store VBO state.

FIXME: write doc.

Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Since:

Coin 2.5

Member Function Documentation

void SoGLVBOElement::initClass (void) [static]This static method initializes static data for the SoMultiTextureCoordinateElement class.

Reimplemented from SoElement.

SbBool SoGLVBOElement::shouldCreateVBO (SoState * state, const int numdata) [static]Returns TRUE if VBO is supported for the current context, and if numdata is between the limits set for VBO rendering.

void SoGLVBOElement::setVertexVBO (SoState * state, SoVBO * vbo) [static]Sets the vertex VBO.

void SoGLVBOElement::setNormalVBO (SoState * state, SoVBO * vbo) [static]Sets the normal VBO.

void SoGLVBOElement::setColorVBO (SoState * state, SoVBO * vbo) [static]Sets the color VBO.

void SoGLVBOElement::setTexCoordVBO (SoState * state, const int unit, SoVBO * vbo) [static]Sets the texture coordinate VBO.

const SoGLVBOElement * SoGLVBOElement::getInstance (SoState * state) [static]Returns a read-only element instance.

SoElement * SoGLVBOElement::copyMatchInfo (void) const [virtual]This function creates a copy of the element that contains enough information to enable the matches() function to work.

Used to help with scenegraph traversal caching operations.

Implements SoElement.

SoGLVBOElement * SoGLVBOElement::getElement (SoState * state) [static, protected]Returns a writable element instance.
