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.

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: improves header and coding style consistency We've had complaints that our Cogl code/headers are a bit "special" so this is a first pass at tidying things up by giving them some consistency. These changes are all consistent with how new code in Cogl is being written, but the style isn't consistently applied across all code yet. There are two parts to this patch; but since each one required a large amount of effort to maintain tidy indenting it made sense to combine the changes to reduce the time spent re indenting the same lines. The first change is to use a consistent style for declaring function prototypes in headers. Cogl headers now consistently use this style for prototypes: return_type cogl_function_name (CoglType arg0, CoglType arg1); Not everyone likes this style, but it seems that most of the currently active Cogl developers agree on it. The second change is to constrain the use of redundant glib data types in Cogl. Uses of gint, guint, gfloat, glong, gulong and gchar have all been replaced with int, unsigned int, float, long, unsigned long and char respectively. When talking about pixel data; use of guchar has been replaced with guint8, otherwise unsigned char can be used. The glib types that we continue to use for portability are gboolean, gint{8,16,32,64}, guint{8,16,32,64} and gsize. The general intention is that Cogl should look palatable to the widest range of C programmers including those outside the Gnome community so - especially for the public API - we want to minimize the number of foreign looking typedefs.

Cogl headers now consistently use this style for prototypes: return_type cogl_function_name (CoglType arg0, CoglType arg1); Not everyone likes this style, but it seems that most of the currently active Cogl developers agree on it. The second change is to constrain the use of redundant glib data types in Cogl. Uses of gint, guint, gfloat, glong, gulong and gchar have all been replaced with int, unsigned int, float, long, unsigned long and char respectively. When talking about pixel data; use of guchar has been replaced with guint8, otherwise unsigned char can be used. The glib types that we continue to use for portability are gboolean, gint{8,16,32,64}, guint{8,16,32,64} and gsize. The general intention is that Cogl should look palatable to the widest range of C programmers including those outside the Gnome community so - especially for the public API - we want to minimize the number of foreign looking typedefs.

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.
