NAME¶

glVertexBindingDivisor, glVertexArrayBindingDivisor - modify the rate at which generic vertex attributes advance

C SPECIFICATION¶

void glVertexBindingDivisor(GLuint bindingindex, GLuint divisor);

void glVertexArrayBindingDivisor(GLuint vaobj, GLuint bindingindex, GLuint divisor);

PARAMETERS¶

vaobj

bindingindex

divisor

DESCRIPTION¶

glVertexBindingDivisor and glVertexArrayBindingDivisor modify the rate at which generic vertex attributes advance when rendering multiple instances of primitives in a single draw command. If divisor is zero, the attributes using the buffer bound to bindingindex advance once per vertex. If divisor is non-zero, the attributes advance once per divisor instances of the set(s) of vertices being rendered. An attribute is referred to as instanced if the corresponding divisor value is non-zero.

glVertexBindingDivisor uses currently bound vertex array object , whereas glVertexArrayBindingDivisor updates state of the vertex array object with ID vaobj.

ERRORS¶

GL_INVALID_VALUE is generated if bindingindex is greater than or equal to the value of GL_MAX_VERTEX_ATTRIB_BINDINGS.

GL_INVALID_OPERATION by glVertexBindingDivisor is generated if no vertex array object is bound.

GL_INVALID_OPERATION is generated by glVertexArrayBindingDivisor if vaobj is not the name of an existing vertex array object.

ASSOCIATED GETS¶

glGet() with arguments GL_MAX_VERTEX_ATTRIB_BINDINGS, GL_VERTEX_BINDING_DIVISOR.
