Vladimír Vondruš	7187ccb48b	Text: ported GlyphCache to older OpenGL and OpenGL ES. * Not requiring ARB_texture_storage, as Texture::setStorage() has already implemented fallback. * Not requiring EXT_texture_rg for single-channel texture on ES2, as this extension might not be available everywhere (unlike in ES3 desktop OpenGL, where Mesa 8/9 with OpenGL 2.1 supports it), fallback to Luminance in GlyphCache and RGB in DistanceFieldGlyphCache, because Luminance might not be renderable everywhere. * Re-enabled building of Text library in all ES PKGBUILDs.	13 years ago
Vladimír Vondruš	5c06009446	Reverted interval in distancefield-related things. 1.0 is taken as shape center (white), 0.0 as shape surroundings (black). It was unintuitive to have it reverted, updated documentation to make it right.	13 years ago
Vladimír Vondruš	b5743c9447	TextureTools: ported distanceField() to OpenGL 2.1 and OpenGL ES. * Older GLSL doesn't have texelFetch() and related things, working around it by using classical texture() and normalized floating-point coordinates. But that needs to have Texture::imageSize() passed, which is not available in OpenGL ES, thus the user must specify it explicitly there. On desktop OpenGL that parameter is ignored. * Older GLSL doesn't have gl_VertexID, thus vertex buffer must be created and vertex data passed expliticly. * GLSL ES 2.0 doesn't have one-component texture format and TextureFormat::Luminance probably isn't renderable anywhere, thus TextureFormat::RGB should be used, although it is inefficient. * Checking for framebuffer completeness, if not complete, nothing is done. * Re-eabled building of TextureTools library in all ES PKGBUILDs.	13 years ago

Vladimír Vondruš	6f63b046ec	Fixed typo copypasted all over the place.	13 years ago
Vladimír Vondruš	b5a6036d48	Use proper ARB_framebuffer_object extension. Separated EXT_framebuffer_object, EXT_framebuffer_blit, EXT_framebuffer_multisample and EXT_packed_depth_stencil don't have the same functionality as ARB_framebuffer_object (e.g. missing GL_FRAMEBUFFER_UNDEFINED in glCheckFramebufferStatus()) and separated read/draw binding is only in EXT_framebuffer_blit, which complicates the internals. Checked with Mesa 8/9 and OpenGL 2.1, current one has ARB_framebuffer_object and also all these four, Mesa 7.7 didn't have EXT_framebuffer_multisample, but that's a long time ago, so not supporting these separate extensions shouldn't be an issue. The problem with unavailable separate binding points remains on OpenGL ES 2.0, there are three different extensions bringing that functionality, thus the code managing the available binding points remains there.	13 years ago

Vladimír Vondruš	261250f074	Shaders: fix port of *Vector shaders to old GLSL. Texture layer binding was never set and there were various GLSL compilation errors.	13 years ago
Vladimír Vondruš	252f489eaa	Don't query shader info log if it contains only '\0' character.	13 years ago
Vladimír Vondruš	e7fd8740bb	Fallback for texture storage feature. It's now possible to call *Texture::setStorage() even if OpenGL 4.2, ARB_texture_storage, OpenGL ES 3.0 or EXT_texture_storage in ES 2.0 is not available, the function will internally use sequence of setImage() calls as fallback. It seems to me that this behavior is better than forcing the user to always check for extension presence and then implementing this functionality again and again. The huge switches for setting proper image format and type are ugly though, but according to specs they must be set even if we are sending no data (which is weird).	13 years ago
Vladimír Vondruš	6d6d6248ab	Reorganize TextureFormat enum a bit. Special RGB values together, RGBA values together, Depth values together, DepthStencil values together. Left sized internal formats in the same order, though.	13 years ago
Vladimír Vondruš	73db7f8d38	Proper reference in TextureFormat enum value documentation.	13 years ago
Vladimír Vondruš	6346e128e1	Always define TextureFormat::RGB565. Don't care if its defined or not, makes it very hard to use that value.	13 years ago
Vladimír Vondruš	adaf8442e7	Fixed typo in TextureFormat::Bptc enum values.	13 years ago
Vladimír Vondruš	6ff652cbbd	Minor cleanup in image and texture format enums. Removed hierarchic and confusing `#ifdef`s.	13 years ago
Vladimír Vondruš	153e5c784a	Sanity check for OpenGL version in Context. I though this check was present since forever, but isn't. Maybe it's hidden somewhere else.	13 years ago
Vladimír Vondruš	c38407c0bb	Abort instead of exit from MAGNUM_ASSERT_*_SUPPORTED() macros.	13 years ago
Vladimír Vondruš	fcc143b14e	Missing #include.	13 years ago
Vladimír Vondruš	f0e9871f10	Platform: #undef another mess from Xorg headers.	13 years ago
Vladimír Vondruš	f0db90c8ef	Added ES2-only support for GL_LUMINANCE{,_ALPHA}. It is deprecated, but many ES2 implementations don't support EXT_texture_rg, thus this is the only way to have single- and two-component textures without wasting precious memory. The enum value isn't exposed on desktop OpenGL and ES3. GL_ALPHA is not supported, as it doesn't bring any new functionality (it is also single-component and thus can be interchanged with GL_LUMINANCE).	13 years ago
Vladimír Vondruš	8453d01ffe	Added section for ES2-compatibility-only features into documentation.	13 years ago
Vladimír Vondruš	8d70e3e3a9	Shaders: allow default construction of MeshVisualizer. While it doesn't make any sense, it is more convenient than writing {} when testing it.	13 years ago
Vladimír Vondruš	20fd1f7afc	Shaders: really ported MeshVisualizer to ES.	13 years ago
Vladimír Vondruš	abc8bfcfc5	Fixed resource import headers.	13 years ago

Vladimír Vondruš	7f51765c36	Oh yeah, coding while drunk. F'ed up in `c2a5919b5a`.	13 years ago
Vladimír Vondruš	f78ac39ab6	Shapes: overlooked `typename`. Spotted by good ol' GCC 4.4. Newer compilers don't bother with that verbosity at all.	13 years ago
Vladimír Vondruš	79c0dc9550	Shaders: use Context::isVersionSupported() instead of ad-hoc solution. Also removed redundant branching for ES.	13 years ago

Vladimír Vondruš	b8b6b63919	SceneGraph: use `virtual` where it hurts less. Having `virtual` destructor in less templated base is better than having it repeated in five times more subclass specializations.	13 years ago
Vladimír Vondruš	392dc54635	Moved BufferTextureFormat enum before the class. Just to make merging into the compatibility branch easier.	13 years ago
Vladimír Vondruš	834d68945e	GCC 4.6 compatibility: weird name conflicts. WTF.	13 years ago
Vladimír Vondruš	d23942f1bc	Fixed comma at the end of enumeration list.	13 years ago
Vladimír Vondruš	b9a72bd3d1	Shaders: ported MeshVisualizer to not require geometry shader. Wireframe width and smoothness isn't ported yet, because I don't fully understand the behavior of standard derivatives in fragment shader.	13 years ago
Vladimír Vondruš	9d1d4b5ef1	Properly number shader sources. Previously the sources were numbered 1, 3, 5 etc., which is wrong.	13 years ago
Vladimír Vondruš	64b00278b8	No need to add `#line` directive also before `#version` line.	13 years ago
