glVertexBindingDivisor: modify the rate at which generic vertex attributes advance
Function Definition
void glVertexBindingDivisor(GLuint bindingindex, GLuint divisor);
- bindingindex
- The index of the binding whose divisor to modify.
- divisor
- The new value for the instance step rate to apply.
Description
glVertexBindingDivisor, modifies 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.
Errors
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.
