GLCLEARBUFFERDATA(3G) OpenGL Manual GLCLEARBUFFERDATA(3G)NAMEglClearBufferData - fill a buffer object's data store with a fixed valueC SPECIFICATIONvoid glClearBufferData(GLenum target, GLenum internalformat, GLenum format, GLenum type, const void * data);PARAMETERStarget Specify the target of the operation. target must be one of the global buffer binding targets. internalformat The internal format with which the data will be stored in the buffer object. size The size, in basic machine units of the range of the data store to fill. format The format of the data in memory addressed by data. type The type of the data in memory addressed by data. data The address of a memory location storing the data to be replicated into the buffer's data store.DESCRIPTIONglClearBufferData fills 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 internalforamt. 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.ERRORSGL_INVALID_ENUM is generated if target not one of the generic buffer binding targets. GL_INVALID_VALUE is generated if no buffer is bound to target. GL_INVALID_ENUM is generated if internalformat is not a sized internal format. GL_INVALID_OPERATION is generated if any part of the buffer's data store is mapped with glMapBufferRange() or glMapBuffer.()SEE ALSOglClearBufferSubData().COPYRIGHTCopyright (C) 2011-2012 Khronos Group.
