glRenderbufferStorage 3G glRenderbufferStorage create and initialize a renderbuffer object's data store void glRenderbufferStorage GLenum target GLenum internalformat GLsizei width GLsizei height target Specifies the renderbuffer target. The symbolic constant must be GL_RENDERBUFFER. internalformat Specifies the color-renderable, depth-renderable, or stencil-renderable format of the renderbuffer. Must be one of the following symbolic constants: GL_RGBA4, GL_RGB565, GL_RGB5_A1, GL_DEPTH_COMPONENT16, or GL_STENCIL_INDEX8. width Specifies the width of the renderbuffer in pixels. height Specifies the height of the renderbuffer in pixels. glRenderbufferStorage establishes the data storage, format, and dimensions of a renderbuffer object's image. Any existing data store for the renderbuffer is deleted and the contents of the new data store are undefined. An implementation may vary its allocation of internal component resolution based on any glRenderbufferStorage parameter (except target), but the allocation and chosen internal format must not be a function of any other state and cannot be changed once they are established. The actual resolution in bits of each component of the allocated image can be queried with glGetRenderbufferParameteriv. GL_INVALID_ENUM is generated if target is not GL_RENDERBUFFER. GL_INVALID_ENUM is generated if internalformat is not an accepted format. GL_INVALID_VALUE is generated if width or height is less than zero or greater than GL_MAX_RENDERBUFFER_SIZE. GL_OUT_OF_MEMORY is generated if the implementation is unable to create a data store with the requested width and height. GL_INVALID_OPERATION is generated if the reserved renderbuffer object name 0 is bound. glGetRenderbufferParameteriv glBindRenderbuffer, glDeleteRenderbuffers, glFramebufferRenderbuffer, glGenRenderbuffers, glGetRenderbufferParameteriv, glIsRenderbuffer Copyright 2008 Khronos Group.
