Fill a buffer object's data store with a fixed value.
||-||Specifies the target to which the buffer object is bound for |
||-||Specifies the name of the buffer object for |
||-||The internal format with which the data will be stored in the buffer object.|
||-||The format of the data in memory addressed by |
||-||The type of the data in memory addressed by |
||-||The address of a memory location storing the data to be replicated into the buffer's data store.|
glClearNamedBufferData fill the entirety of a buffer object's data store with data from client memory.
Data, initially supplied in a format specified by
format in data type
type is read from the memory address given by
data and converted into the internal representation given by
internalformat , which must be one of the following sized internal formats:
This converted data is then replicated throughout the buffer object's data store. If
data is NULL, then the buffer's data store is filled with zeros.
GL_INVALID_ENUM is generated by
target is not one of the generic buffer binding targets.
GL_INVALID_VALUE is generated by
glClearBufferData if no buffer is bound
GL_INVALID_OPERATION is generated by
buffer is not the name of an existing buffer object.
GL_INVALID_ENUM is generated if
internalformat is not one of the valid sized internal formats listed in the table above.
GL_INVALID_OPERATION is generated if any part of the specified range of the buffer object is mapped with glMapBufferRange or glMapBuffer , unless it was mapped with the
GL_MAP_PERSISTENT_BIT bit set in the
GL_INVALID_VALUE is generated if
format is not a valid format, or
type is not a valid type.
