[cogl] Improve ability to break out into raw OpenGL via begin/end mechanism Although we wouldn't recommend developers try and interleve OpenGL drawing with Cogl drawing - we would prefer patches that improve Cogl to avoid this if possible - we are providing a simple mechanism that will at least give developers a fighting chance if they find it necissary. Note: we aren't helping developers change OpenGL state to modify the behaviour of Cogl drawing functions - it's unlikley that can ever be reliably supported - but if they are trying to do something like: - setup some OpenGL state. - draw using OpenGL (e.g. glDrawArrays() ) - reset modified OpenGL state. - continue using Cogl to draw They should surround their blocks of raw OpenGL with cogl_begin_gl() and cogl_end_gl(): cogl_begin_gl (); - setup some OpenGL state. - draw using OpenGL (e.g. glDrawArrays() ) - reset modified OpenGL state. cogl_end_gl (); - continue using Cogl to draw Again; we aren't supporting code like this: - setup some OpenGL state. - use Cogl to draw - reset modified OpenGL state. When the internals of Cogl evolves, this is very liable to break. cogl_begin_gl() will flush all internally batched Cogl primitives, and emit all internal Cogl state to OpenGL as if it were going to draw something itself. The result is that the OpenGL modelview matrix will be setup; the state corresponding to the current source material will be setup and other world state such as backface culling, depth and fogging enabledness will be also be sent to OpenGL. Note: no special material state is flushed, so if developers want Cogl to setup a simplified material state it is the their responsibility to set a simple source material before calling cogl_begin_gl. E.g. by calling cogl_set_source_color4ub(). Note: It is the developers responsibility to restore any OpenGL state that they modify to how it was after calling cogl_begin_gl() if they don't do this then the result of further Cogl calls is undefined.

Add a Cogl texture 3D backend This adds a publicly exposed experimental API for a 3D texture backend. There is a feature flag which can be checked for whether 3D textures are supported. Although we require OpenGL 1.2 which has 3D textures in core, GLES only provides them through an extension so the feature can be used to detect that. The textures can be created with one of two new API functions :- cogl_texture_3d_new_with_size and cogl_texture_3d_new_from_data There is also internally a new_from_bitmap function. new_from_data is implemented in terms of this function. The two constructors are effectively the only way to upload data to a 3D texture. It does not work to call glTexImage2D with the GL_TEXTURE_3D target so the virtual for cogl_texture_set_region does nothing. It would be possible to make cogl_texture_get_data do something sensible like returning all of the images as a single long image but this is not currently implemented and instead the virtual just always fails. We may want to add API specific to the 3D texture backend to get and set a sub region of the texture. All of those three functions can throw a GError. This will happen if the GPU does not support 3D textures or it does not support NPOTs and an NPOT size is requested. It will also fail if the FBO extension is not supported and the COGL_TEXTURE_NO_AUTO_MIPMAP flag is not given. This could be avoided by copying the code for the GL_GENERATE_MIPMAP TexParameter fallback, but in the interests of keeping the code simple this is not yet done. This adds a couple of functions to cogl-texture-driver for uploading 3D data and querying the 3D proxy texture. prep_gl_for_pixels_upload_full now also takes sets the GL_UNPACK_IMAGE_HEIGHT parameter so that 3D textures can have padding between the images. Whenever 3D texture is uploading, both the height of the images and the height of all of the data is specified (either explicitly or implicilty from the CoglBitmap) so that the image height can be deduced by dividing by the depth.

[cogl] Move the texture filters to be a property of the material layer The texture filters are now a property of the material layer rather than the texture object. Whenever a texture is painted with a material it sets the filters on all of the GL textures in the Cogl texture. The filter is cached so that it won't be changed unnecessarily. The automatic mipmap generation has changed so that the mipmaps are only generated when the texture is painted instead of every time the data changes. Changing the texture sets a flag to mark that the mipmaps are dirty. This works better if the FBO extension is available because we can use glGenerateMipmap. If the extension is not available it will temporarily enable automatic mipmap generation and reupload the first pixel of each slice. This requires tracking the data for the first pixel. The COGL_TEXTURE_AUTO_MIPMAP flag has been replaced with COGL_TEXTURE_NO_AUTO_MIPMAP so that it will default to auto-mipmapping. The mipmap generation is now effectively free if you are not using a mipmap filter mode so you would only want to disable it if you had some special reason to generate your own mipmaps. ClutterTexture no longer has to store its own copy of the filter mode. Instead it stores it in the material and the property is directly set and read from that. This fixes problems with the filters getting out of sync when a cogl handle is set on the texture directly. It also avoids the mess of having to rerealize the texture if the filter quality changes to HIGH because Cogl will take of generating the mipmaps if needed.

CoglMaterialWrapMode
cogl-material: Add support for setting the wrap mode for a layer Previously, Cogl's texture coordinate system was effectively always GL_REPEAT so that if an application specifies coordinates outside the range 0→1 it would get repeated copies of the texture. It would however change the mode to GL_CLAMP_TO_EDGE if all of the coordinates are in the range 0→1 so that in the common case that the whole texture is being drawn with linear filtering it will not blend in edge pixels from the opposite sides. This patch adds the option for applications to change the wrap mode per layer. There are now three wrap modes: 'repeat', 'clamp-to-edge' and 'automatic'. The automatic map mode is the default and it implements the previous behaviour. The wrap mode can be changed for the s and t coordinates independently. I've tried to make the internals support setting the r coordinate but as we don't support 3D textures yet I haven't exposed any public API for it. The texture backends still have a set_wrap_mode virtual but this value is intended to be transitory and it will be changed whenever the material is flushed (although the backends are expected to cache it so that it won't use too many GL calls). In my understanding this value was always meant to be transitory and all primitives were meant to set the value before drawing. However there were comments suggesting that this is not the expected behaviour. In particular the vertex buffer drawing code never set a wrap mode so it would end up with whatever the texture was previously used for. These issues are now fixed because the material will always set the wrap modes. There is code to manually implement clamp-to-edge for textures that can't be hardware repeated. However this doesn't fully work because it relies on being able to draw the stretched parts using quads with the same values for tx1 and tx2. The texture iteration code doesn't support this so it breaks. This is a separate bug and it isn't trivially solved. When flushing a material there are now extra options to set wrap mode overrides. The overrides are an array of values for each layer that specifies an override for the s, t or r coordinates. The primitives use this to implement the automatic wrap mode. cogl_polygon also uses it to set GL_CLAMP_TO_BORDER mode for its trick to render sliced textures. Although this code has been added it looks like the sliced trick has been broken for a while and I haven't attempted to fix it here. I've added a constant to represent the maximum number of layers that a material supports so that I can size the overrides array. I've set it to 32 because as far as I can tell we have that limit imposed anyway because the other flush options use a guint32 to store a flag about each layer. The overrides array ends up adding 32 bytes to each flush options struct which may be a concern. http://bugzilla.openedhand.com/show_bug.cgi?id=2063

cogl-material: Add support for setting the wrap mode for a layer Previously, Cogl's texture coordinate system was effectively always GL_REPEAT so that if an application specifies coordinates outside the range 0→1 it would get repeated copies of the texture. It would however change the mode to GL_CLAMP_TO_EDGE if all of the coordinates are in the range 0→1 so that in the common case that the whole texture is being drawn with linear filtering it will not blend in edge pixels from the opposite sides. This patch adds the option for applications to change the wrap mode per layer. There are now three wrap modes: 'repeat', 'clamp-to-edge' and 'automatic'. The automatic map mode is the default and it implements the previous behaviour. The wrap mode can be changed for the s and t coordinates independently. I've tried to make the internals support setting the r coordinate but as we don't support 3D textures yet I haven't exposed any public API for it.
