GLVERTEXATTRIBBINDIN(3G) OpenGL Manual GLVERTEXATTRIBBINDIN(3G) NAME
glVertexAttribBinding - associate a vertex attribute and a vertex buffer binding C SPECIFICATION
void glVertexAttribBinding(GLuint attribindex, GLuint bindingindex); PARAMETERS
attribindex The index of the attribute to associate with a vertex buffer binding. bindingindex The index of the vertex buffer binding with which to associate the generic vertex attribute. DESCRIPTION
glVertexAttribBinding, establishes an association between the generic vertex attribute whose index is given by attribindex and a vertex buffer binding whose index is given by bindingindex. attribindex must be less than the value of GL_MAX_VERTEX_ATTRIBS and bindingindex must be less than the value of GL_MAX_VERTEX_ATTRIB_BINDINGS. ERRORS
GL_INVALID_VALUE is generated if attribindex is greater than or equal to the value of GL_MAX_VERTEX_ATTRIBS. GL_INVAILD_VALUE is generated if bindingindex is greater than or equal to the value of GL_MAX_VERTEX_ATTRIB_BINDINGS. GL_INVALID_OPERATION is generated if no vertex array object is bound. ASSOCIATED GETS
glGet() with arguments GL_MAX_VERTEX_ATTRIB_BINDINGS, GL_VERTEX_BINDING_DIVISOR. SEE ALSO

GLVERTEXATTRIBFORMAT(3G) OpenGL Manual GLVERTEXATTRIBFORMAT(3G) NAME
glVertexAttribFormat - specify the organization of vertex arrays C SPECIFICATION
void glVertexAttribFormat(GLuint attribindex, GLint size, GLenum type, GLboolean normalized, GLuint relativeoffset); void glVertexAttribIFormat(GLuint attribindex, GLint size, GLenum type, GLuint relativeoffset); void glVertexAttribLFormat(GLuint attribindex, GLint size, GLenum type, GLuint relativeoffset); PARAMETERS
attribindex The generic vertex attribute array being described. size The number of values per vertex that are stored in the array. type The type of the data stored in the array. normalized The distance between elements within the buffer. relativeoffset The distance between elements within the buffer. DESCRIPTION
glVertexAttribFormat, glVertexAttribIFormat and glVertexAttribLFormat specify the organization of data in vertex arrays. attribindex specifies the index of the generic vertex attribute array whose data layout is being described, and must be less than the value of GL_MAX_VERTEX_ATTRIBS. size determines the number of components per vertex are allocated to the specifed attribute and must be 1, 2, 3 or 4. type indicates the type of the data. If type is one of GL_BYTE, GL_SHORT, GL_INT, GL_FIXED, GL_FLOAT, GL_HALF_FLOAT, and GL_DOUBLE indicate types GLbyte, GLshort, GLint, GLfixed, GLfloat, GLhalf, and GLdouble, respectively; the values GL_UNSIGNED_BYTE, GL_UNSIGNED_SHORT, and GL_UNSIGNED_INT indicate types GLubyte, GLushort, and GLuint, respectively; and the values GL_INT_2_10_10_10_REV and GL_UNSIGNED_INT_2_10_10_10_REV indicating respectively four signed or unsigned elements packed into a single GLuint. glVertexAttribLFormat is used to specify layout for data associated with a generic attribute variable declared as 64-bit double precision components. For glVertexAttribLFormat, type must be GL_DOUBLE. In contrast to glVertexAttribFormat, which will cause data declared as GL_DOUBLE to be converted to 32-bit representation, glVertexAttribLFormat causes such data to be left in its natural, 64-bit representation. For glVertexAttribFormat, if normalized is GL_TRUE, then integer data is normalized to the range [-1, 1] or [0, 1] if it is signed or unsigned, respectively. If noramlized is GL_FALSE then integer data is directly converted to floating point. relativeoffset is the offset, measured in basic machine units of the first element relative to the start of the vertex buffer binding this attribute fetches from. glVertexAttribFormat should be used to describe vertex attribute layout for floating-point vertex attributes, glVertexAttribIFormat should be used to describe vertex attribute layout for integer vertex attribute and glVertexAttribLFormat should be used to describe the layout for 64-bit vertex attributes. Data for an array specified by glVertexAttribIFormat will always be left as integer values; such data are referred to as pure integers. ERRORS
GL_INVAILD_VALUE is generated if attribindex is greater than or equal to the value of GL_MAX_VERTEX_ATTRIBS. GL_INVALID_VALUE is generated if size is not one of the accepted values. GL_INVALID_VALUE is generated if relativeoffset is greater than the value of GL_MAX_VERTEX_ATTRIB_RELATIVE_OFFSET. GL_INVALID_ENUM is generated if type is not one of the accepted tokens. GL_INVALID_OPERATION is generated if no vertex array object is bound. ASSOCIATED GETS
glGet() with arguments GL_MAX_VERTEX_ATTRIB_BINDINGS, or GL_MAX_VERTEX_ATTRIB_RELATIVE_OFFSET. glGetVertexAttrib() with argument GL_VERTEX_ATTRIB_RELATIVE_OFFSET. SEE ALSO
