* clutter/cogl/gl/cogl-texture.c (cogl_texture_polygon)
	(_cogl_texture_quad_sw, _cogl_texture_quad_hw):
	* clutter/cogl/gles/cogl-texture.c (cogl_texture_polygon)
	(_cogl_texture_quad_sw, _cogl_texture_quad_hw): Enable backface
	culling in GL if it is requested.

e43b7ddd3d Bug 1196 - Texture border drawing problems
* clutter/cogl/gl/cogl-texture.c (_cogl_texture_upload_subregion_to_gl)
	(_cogl_texture_upload_to_gl):

	* clutter/cogl/gles/cogl-texture.c (_cogl_texture_upload_to_gl)
	(_cogl_texture_upload_subregion_to_gl):
	
	When uploading data to a sliced texture, fill the waste pixels
	with copies of the edge of the real texture data. Otherwise the
	value of the waste pixels are undefined so it will show artifacts
	when the texture is scaled with GL_LINEAR and the pixels are
	blended in.

* clutter/cogl/gl/cogl-texture.c (cogl_texture_set_region):
	* clutter/cogl/gles/cogl-texture.c (cogl_texture_set_region):
	Don't attempt to upload any data if the width or height of the
	subregion is zero. Thanks to Gwenole Beauchesne.

76faa8c7a6 Bug 1044 - cogl_get_viewport error
* clutter/cogl/gles/cogl.c (cogl_get_viewport): Use glGetIntegerv
	instead of glGetFixedv to read the viewport because the latter
	converts incorrectly on some hardware.

	* clutter/cogl/gles/cogl.c: 
	* clutter/cogl/cogl.h.in: Add cogl_clip_stack_save,
	cogl_clip_stack_restore, cogl_viewport and cogl_frustum.

	* clutter/cogl/gl/cogl-fbo.h: 
	* clutter/cogl/gl/cogl-fbo.c: Try to attach a stencil buffer when
	creating an FBO.

	* clutter/cogl/common/cogl-clip-stack.c: Add functions to save and
	restore the whole state of the stack.

	* clutter/clutter-texture.c (clutter_texture_paint): When
	rendering the FBO source, setup a temporary asymmetric perspective
	projection matrix to render it as it would appear on screen.

d4da3a3e2a * clutter/cogl/gles/cogl-gles2-wrapper.h:
* clutter/cogl/gles/cogl-gles2-wrapper.c: All of the settings and
	uniforms are now proxied into COGL variables instead of setting
	the GL uniforms directly. Just before glDrawArrays is executed a
	shader is generated using the given settings to avoid using 'if'
	statements. The shaders are cached.

	* clutter/cogl/gles/cogl-fixed-vertex-shader.glsl: 
	* clutter/cogl/gles/cogl-fixed-fragment-shader.glsl: The shaders
	are now split into parts using comments instead of 'if' statements
	so that the simplest shader can be generated on the fly.

	* clutter/cogl/gles/stringify.sh: Now splits up the shader sources
	into separate C strings where deliminated by special comments.

	* clutter/cogl/gles/cogl-program.h: 
	* clutter/cogl/gles/cogl-program.c: A custom shader can no longer
	be directly linked with the fixed-functionality replacement
	because the replacement changes depending on the settings. Instead
	the bound shader is linked with the appropriate replacement shader
	just before glDrawArrays is executed. The custom uniform variables
	must also be proxied through COGL variables because their location
	can change when relinked.

dff84094ff Bug 918 - Group doesn't clip if it's children are clipped
* clutter/cogl/common/cogl-clip-stack.h: 
	* clutter/cogl/common/cogl-clip-stack.c: Added functions to
	maintain a stack of clipping rectangles.

	* clutter/cogl/gles/cogl.c: 
	* clutter/cogl/gl/cogl.c: The cogl_clip_set and unset functions
	have moved into cogl-clip-stack.c which calls back to cogl.c to
	set the actual rectangles. Multiple clip rectangles are combined
	by merging the stencil buffers.

	* clutter/cogl/gles/cogl-primitives.c (_cogl_path_fill_nodes): 
	* clutter/cogl/gl/cogl-primitives.c (_cogl_path_fill_nodes): Merge
	the stencil buffer with the contents of the clipping stack after
	drawing the path.

	* clutter/cogl/gles/cogl-context.h (CoglContext): 
	* clutter/cogl/gl/cogl-context.h (CoglContext): Store the number
	of available stencil bits.

	* clutter/eglnative/clutter-egl.h: 
	* clutter/eglnative/clutter-backend-egl.h: Include
	clutter-egl-headers.h instead of including the GL headers directly
	so it can include gl2.h when building for GLES 2.

	* clutter/eglnative/Makefile.am (libclutter_eglnative_la_SOURCES):
	Added clutter-egl-headers.h

	* clutter/cogl/gles/cogl-fixed-fragment-shader.glsl: GLES 2
	doesn't provide a default precision for floats in the fragment
	shader and it will reject the shader if there isn't one.

8bdb98736d Applied 'final patch' from bug #874
* clutter/cogl/gles/cogl.c:
	* clutter/cogl/gl/cogl.c: The clip planes are now set using the
	inverse projection matrix as the modelview matrix so that they can
	be specified in screen coordinates.

	* clutter/cogl/gles/cogl-context.h (CoglContext):
	* clutter/cogl/gl/cogl-context.h (CoglContext): Added a member to
	cache the inverse projection matrix

	* clutter/clutter-fixed.h: Added a constant for converting from
	radians to degrees.

	* clutter/clutter-fixed.c (clutter_atani, clutter_atan2i): Added

42ed195f01 * clutter/cogl/gles/cogl-gles2-wrapper.h: The uniform numbers are
now stored in a separate struct so they can be stored for
	application program objects as well.

	* clutter/cogl/gles/cogl.c: Moved stub shader functions into
	separate files.
	(_cogl_features_init): Report support for the shaders feature on
	GLES 2

	* clutter/cogl/gles/cogl-shader.c:
	* clutter/cogl/gles/cogl-program.h:
	* clutter/cogl/gles/cogl-program.c: Separate files to handle
	shaders on programs on GLES. If version 1.1 is being used then the
	stub functions which all fail are still used.

	* clutter/cogl/gles/cogl-gles2-wrapper.c
	(cogl_gles2_wrapper_init, cogl_gles2_wrapper_bind_attributes),
	(cogl_gles2_wrapper_get_uniforms): Move the uniforms and attribute
	bindings into a separate function so they can be used to bind on
	application shaders as well.
	(cogl_gles2_wrapper_update_matrix): Now takes a parameter and is
	no longer static so that it can be used to update all of the
	matrices when a new shader is bound.

	* clutter/cogl/gles/cogl-defines.h.in: Use GL_COMPILE_STATUS for
	CGL_OBJECT_COMPILE_STATUS if the latter isn't available (for
	example on GLES 2).

	* clutter/cogl/gles/cogl-context.h (CoglContext): Added handle
	arrays for programs and shaders.

	* clutter/cogl/gles/cogl-gles2-wrapper.c
	(cogl_wrap_glGetIntegerv): Added a wrapper for glGetIntegerv so
	that it can report zero clip planes.

	* clutter/cogl/gles/cogl.c:
	* clutter/cogl/gles/cogl-texture.c: Use the wrapped version of
	glGetIntegerv

	* clutter/cogl/gles/cogl-primitives.c (_cogl_path_fill_nodes): Use
	_cogl_features_available to check for the stencil buffer instead
	of an #ifdef. The stencil buffer is available in the default
	profile for the GLES 2 simulator.

(cogl_gles2_wrapper_init): Get uniforms for fog parameters and
    	initialise them.
    	(cogl_wrap_glDrawArrays): Store the modelview matrix in a uniform
    	as well so that it can be used for fogging calculations.
    	(cogl_wrap_glEnable, cogl_wrap_glDisable): Enable/disable fogging.
    	(cogl_wrap_glFogx, cogl_wrap_glFogxv): Fill in wrapper to set
    	fogging parameters.

    	* clutter/cogl/gles/cogl-fixed-vertex-shader.glsl: Calculate the

	texture image data.

	* clutter/cogl/gles/cogl-gles2-wrapper.h:
	* clutter/cogl/gles/cogl-gles2-wrapper.c: Added a wrapper for
	glTexParameteri so that it can ignore requests to set
	GL_GENERATE_MIPMAP. Added a wrapper for glGenerateMipmap that does
	nothing on GLES 1

70dbc03734 GLES 2 backend
* clutter/eglx/clutter-stage-egl.h:
	* clutter/eglx/clutter-egl-headers.h:
	* clutter/eglx/clutter-backend-egl.h:
	* clutter/eglx/Makefile.am: Include the GLES and EGL headers via
	clutter-egl-headers.h so that the right version can be used
	depending on whether the GLES 2 wrapper is being used.

	* configure.ac: Added an automake conditional for whether the GLES
	2 wrapper should be used.

	* clutter/eglx/clutter-stage-egl.c (clutter_stage_egl_realize):
	Remove the call to glGetIntegerv to get the max texture size. It
	was being called before the GL context was bound so it didn't work
	anyway and it was causing trouble for the GLES 2 simulator.

	* clutter/cogl/gles/stringify.sh: Shell script to convert the
	shaders into a C string.

	* clutter/cogl/gles/cogl-gles2-wrapper.h:
	* clutter/cogl/gles/cogl-gles2-wrapper.c: Wrappers for most of the
	missing GL functions in GLES 2.

	* clutter/cogl/gles/cogl-fixed-fragment-shader.glsl:
	* clutter/cogl/gles/cogl-fixed-vertex-shader.glsl: New shaders for
	GLES 2

	* clutter/cogl/gles/cogl-defines.h.in: Use the @CLUTTER_GL_HEADER@
	macro instead of always using the GLES 1 header.

	* clutter/cogl/gles/cogl-context.h (CoglContext): Include a field
	for the state of the GLES 2 wrapper.

	* clutter/cogl/gles/cogl-texture.c:
	* clutter/cogl/gles/cogl-primitives.c:
	* clutter/cogl/gles/cogl.c: Use wrapped versions of the GL
	functions where neccessary.

	* clutter/cogl/gles/Makefile.am: Add sources for the GLES 2
	wrapper and an extra build step to put the GLSL files into a C
	string whenever the files change.

f9e43c440b * clutter/cogl/gl/cogl.c (error_string):
* clutter/cogl/gles/cogl.c (error_string): Rename to
	_cogl_error_string and remove the static scoping so that it can be
	called in cogl-texture etc.

	* clutter/cogl/gl/cogl-texture.c (cogl_texture_new_from_foreign):
	* clutter/cogl/gles/cogl-texture.c (cogl_texture_new_from_foreign):
	GE(*) can't be used to wrap around calls that use the return
	value.

	* clutter/cogl/gl/cogl-texture.c (_cogl_texture_quad_sw)
	(_cogl_texture_quad_hw, cogl_texture_polygon): Remove GE(*)
	wrapper around calls in the middle of a glBegin/glEnd pair which
	otherwise always generate an error because glGetError can only be
	called outside of the pair.

	* clutter/cogl/gl/cogl-internal.h: Include stdio.h when definig
	COGL_DEBUG and declare a prototype for _cogl_error_string.

	* clutter/cogl/gles/cogl-internal.h: Match GE(*) macro to GL
	version.

9f5a8edc64 * clutter/cogl/gles/cogl-texture.c:
(_cogl_texture_download_from_gl:) Only comment out the broken
	check for framebuffer alpha bits, not the check for alpha in
	texture format.
2008-05-21 10:00:08 +00:00
Ivan Leben
2008a03a6b * clutter/cogl/gles/cogl-texture.c:
(cogl_texture_download_from_gl:) Implemented a workaround
	for missing alpha framebuffer channel. There are still
	some issues with detecting whether alpha is present in the
	framebuffer. See comments in code. Test-cogl-tex-getset now
	successfully retrieves a RGBA texture image data.
2008-05-20 10:37:36 +00:00
Ivan Leben
3d9f83019d * clutter/cogl/gles/cogl-texture.c:
(cogl_texture_download_from_gl:) Store old blending factors
	and restore them when done. The lack of ability to retrieve
	the alpha channel now more noticable in test-cogl-tex-getset
	since the edges of the hand are not antialiased.

	* clutter/cogl/gl(es)/cogl-internal.h: Declare
	cogl_blend_func to avoid "implicit implementation" compile
	warning.
2008-05-19 15:21:56 +00:00
Ivan Leben
f2d701c809 * clutter/cogl/gl(es)/cogl.c: New internal function
cogl_blend_func caches blending setup much like cogl_enable
	does with the enable flags. This separates blending factors
	setup from the enable/disable operation in preparation of
	the texture image retrieval fix for alpha channel on GLES.
	(cogl_enable:) Does not modify blending factors anymore.

	* clutter/cogl/gl(es)/cogl-context.h: CoglContext holds two
	new variables to cache blending src and dst factors.

	* clutter/cogl/gl(es)/cogl-context.c:
	(cogl_create_context:) Initialize blending factors.

	* clutter/cogl/gles/cogl-texture.c:
	(cogl_texture_download_from_gl:) Set blending factors to
	CGL_ONE, CGL_ZERO which fixes the slighlty improper behavior
	where source colour was actually multiplied with its alpha
	value in the result (not noticable on current tests).

ef084cfa95 * clutter/cogl/cogl.h.in:
* clutter/cogl/gl(es)/cogl-texture.h:
	* clutter/cogl/gl(es)/cogl-texture.c:
	cogl_texture_new_* functions take a gboolean auto_mipmap argument.
	If TRUE automatic mipmap generation is enabled during the process
	of slice texture object creation.
	(cogl_texture_new_from_foreign:) now allows mipmap min filter

	* tests/test-cogl-tex-getset.c:
	Pass FALSE for auto_mipmap to cogl_texture_new_*.

	* clutter/pango/pangoclutter-render.c:
	(tc_get:) Pass TRUE to cogl_texture_new_with_size and use mipmap
	min filter for nicer glyphs at small scales. As a result test-text
	has gone all beautiful now.

Øyvind Kolås
6562d30ab0 * clutter/cogl/gles/cogl-primitives.c: (_cogl_path_fill_nodes):

19058afe82 Removed COGLhandle and changed shader and program functions to be
wrapped in reference-counted CoglHandles instead.

	* clutter/cogl/gl/cogl-shader.c: 
	* clutter/cogl/gl/cogl-shader.h: 
	* clutter/cogl/gl/cogl-program.c: 
	* clutter/cogl/gl/cogl-program.h: 
	New files to hold the shader and program functions.

	* clutter/cogl/gl/cogl.c: Removed shader and program functions.

	* clutter/cogl/common/cogl-handle.h: New header to define
	COGL_HANDLE_DEFINE which helps build functions to create
	reference-counted handles. This reduces the amount of duplicated
	code.

	* clutter/cogl/gl/cogl-texture.c: 
	* clutter/cogl/gles/cogl-texture.c: 
	* clutter/cogl/gl/cogl-fbo.c: Converted to use COGL_HANDLE_DEFINE

        * clutter/cogl/gl/cogl.c:
        * clutter/cogl/gles/cogl.c:
       Disable the depth test and buffer as has some strange side
       effects, mainly on x/y axis rotation with multiple layers at
       same depth (eg rotating text on a bg has very strange
       effect). Seems no clean 100% effective way to fix without other
       odd issues.. So for now move to application to handle and add
       cogl_enable_depth_test() as for custom actors (i.e groups) to
       enable if need be.
