5.5. DISPLAY LISTS 466 the effect of creating an empty display list for each of the indices n, . . . , n + s − 1, so that these indices all become used. GenLists returns 0 if there is no group of s contiguous previously unused display list indices, or if s = 0. boolean IsList( uint list ); returns TRUE if list is the index of some display list. A contiguous group of display lists may be deleted by calling void DeleteLists( uint list, sizei range ); where list is the index of the first display list to be deleted and range is the number of display lists to be deleted. All information about the display lists is lost, and the indices become unused. Indices to which no display list corresponds are ignored. If range = 0, nothing happens. 5.5.1 Commands Not Usable In Display Lists Certain commands, when called while compiling a display list, are not compiled into the display list but are executed immediately. These commands fall in several categories including Display lists: GenLists and DeleteLists. Render modes: FeedbackBuffer, SelectBuffer, and RenderMode. Vertex arrays: ClientActiveTexture, ColorPointer, EdgeFlagPointer, Fog- CoordPointer, IndexPointer, InterleavedArrays, NormalPointer, Secondary- ColorPointer, TexCoordPointer, VertexAttribPointer, VertexAttribIPointer, VertexAttribLPointer, VertexPointer, PrimitiveRestartIndex, GenVertexArrays, DeleteVertexArrays, and BindVertexArray. Client state: EnableClientState, DisableClientState, EnableVertexAttrib- Array, DisableVertexAttribArray, PushClientAttrib, and PopClientAttrib. Pixels and textures: PixelStore, ReadPixels, GenTextures, DeleteTextures, AreTexturesResident, TexBuffer, TexStorage1D, TexStorage2D, TexStorage3D, and GenerateMipmap. Occlusion queries: GenQueries and DeleteQueries. Buffer objects: GenBuffers, DeleteBuffers, BindBuffer, BindBufferRange, BindBufferBase, TransformFeedbackVaryings, MemoryBarrier, BufferData, BufferSubData, MapBuffer, MapBufferRange, FlushMappedBufferRange, and UnmapBuffer. Sampler objects: GenSamplers and DeleteSamplers. Transform feedback objects: GenTransformFeedbacks and DeleteTransformFeedbacks. OpenGL 4.2 (Compatibility Profile) - April 27, 2012
5.5. DISPLAY LISTS 467 Framebuffer and renderbuffer objects: GenFramebuffers, BindFramebuffer, DeleteFramebuffers, CheckFramebufferStatus, GenRenderbuffers, BindRenderbuffer, DeleteRenderbuffers, RenderbufferStorage, RenderbufferStorageMultisample, FramebufferTexture, FramebufferTexture1D, FramebufferTexture2D, FramebufferTexture3D, FramebufferTextureLayer, FramebufferRenderbuffer, and BlitFramebuffer. Program and shader objects: CreateProgram, CreateShader, Create- ShaderProgram, GenProgramPipelines, BindProgramPipelines DeleteProgramPipelines, DeleteProgram, DeleteShader, AttachShader, DetachShader, BindAttribLocation, BindFragDataLocation, CompileShader, ShaderSource, LinkProgram, and ValidateProgram. GL command stream management: ClientWaitSync, FenceSync, Finish, and Flush. Other queries: All query commands whose names begin with Get and Is (see chapter 6). An INVALID_OPERATION error is generated if the commands DrawArraysInstanced or DrawElementsInstanced (see section 2.8.2) are called during display list compilation. Commands that source data from buffer objects dereference the buffer object data in question at display list compile time, rather than encoding the buffer ID and buffer offset into the display list. Only GL commands that are executed immediately, rather than being compiled into a display list, are permitted to use a buffer object as a data sink. TexImage3D, TexImage2D, TexImage1D, Histogram, and ColorTable are executed immediately when called with the corresponding proxy arguments PROXY_TEXTURE_3D, PROXY_TEXTURE_2D_ARRAY, or PROXY_TEXTURE_- CUBE_MAP_ARRAY; PROXY_TEXTURE_2D, PROXY_TEXTURE_1D_ARRAY, or PROXY_TEXTURE_CUBE_MAP; PROXY_TEXTURE_1D; PROXY_HISTOGRAM; and PROXY_COLOR_TABLE, PROXY_POST_CONVOLUTION_COLOR_TABLE, or PROXY_POST_COLOR_MATRIX_COLOR_TABLE. When a program object is in use, a display list may be executed whose vertex attribute calls do not match up exactly with what is expected by the vertex shader contained in that program object. Handling of this mismatch is described in section 2.14.6. Display lists require one bit of state to indicate whether a GL command should be executed immediately or placed in a display list. In the initial state, commands are executed immediately. If the bit indicates display list creation, an index is required to indicate the current display list being defined. Another bit indicates, during display list creation, whether or not commands should be executed as they are compiled into the display list. One integer is required for the current ListBase OpenGL 4.2 (Compatibility Profile) - April 27, 2012
