Vladimír Vondruš	eb24db9b5f	Framebuffer-related limit queries. Also printing the values in magnum-info.	13 years ago
Vladimír Vondruš	23945c1d9f	Fix linker errors with Framebuffer::BufferAttachment::* on Windows.	13 years ago
Vladimír Vondruš	e19154be5e	Reducing pointer chasings, part 3a: less pointer passing in root namespace. Passing pointer as function parameter will now mean that it is possible to pass `nullptr`. Some code examples now look like the parameter is copied instead of referenced, which is misleading. Updated the documentation to reflect that more clearly.	13 years ago
Vladimír Vondruš	d04b308aa3	Reducing pointer chasings, part 1: method chaining via references. Makes some cases less consistent (and some convenience shortcuts impossible), but goes well with the attitude "don't use pointer when it can't be null".	13 years ago
Vladimír Vondruš	e923034dbf	Added functions for checking (default) framebuffer state.	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	f7aa2c05a6	Deinlined heavy functions and removed redundant `inline` everywhere else.	13 years ago
Vladimír Vondruš	cb06737640	glDrawBuffer() is not available in ES3. Using glDrawBuffers() also in this case.	13 years ago
Vladimír Vondruš	6a5d75d1e4	Relicensing to MIT/Expat license, part 2: headers.	13 years ago
Vladimír Vondruš	23ba74c8c3	Added missing method chaining to framebuffer configuration functions.	13 years ago
Vladimír Vondruš	2d2d1c07f4	Using new type aliases in whole root Magnum namespace.	13 years ago
Vladimír Vondruš	a7541e68d8	Doc++	14 years ago
Vladimír Vondruš	d59297aeeb	Implemented ARB_invalidate_subdata GL 4.3 extension. Framebuffer invalidation is also available in OpenGL ES 3.0 and ES 2.0 using EXT_discard_framebuffer extension.	14 years ago
Vladimír Vondruš	80cb4eb8e5	Reworked framebuffer attachment enums. Instead of having pair of functions for depth/stencil and color attachments this is now solved using specialized class. It is now more descriptive, as specifying color attachment is now done explicitly using Framebuffer::ColorAttachment(2) instead of just `2`. Specifying "no attachment" is now also done explicitly using Framebuffer::DrawAttachment::None instead of `-1`. Also updated related documentation.	14 years ago
Vladimír Vondruš	a45b4fba8b	Using Rectangle in framebuffer.	14 years ago
Vladimír Vondruš	e5db59aad5	Removed "wontfix" TODOs. * Calling Mesh::draw() with parameter to start on arbitrary vertex index might give users more freedom than they want to have (e.g. lines rendered where gaps should be, broken triangle strips...). Single-precision floats have meaningful precision of ~6 decimal places, everything after that would be random garbage anyway, so we don't need anything "more precise" for icosphere. * Texture1D can have only one target and it can be used as framebuffer target.	14 years ago
Vladimír Vondruš	7d6b7a4b6b	Using EXT_direct_state_access in framebuffers. Framebuffer::attach*() doesn't need the target at all (meaning the attachment will be used for both reading and drawing), another misunderstanding on my side. Now the extension is used on all places where it can be used (except for unimplemented features).	14 years ago
Vladimír Vondruš	7d04b7d511	Doc++ Basic framebuffer usage, mentioned framebuffer attachments in shader documentation.	14 years ago
Vladimír Vondruš	72d48ac3e7	More intuitive framebuffer attachment mapping.	14 years ago
Vladimír Vondruš	7e66a09461	Marking all constructors explicit, except for matrix and vector classes. It prevents unwanted implicit conversions from e.g. nullptr to Camera, Vector2 to Physics::Point etc. By making all the constructors explicit it is easier to routinely add the keyword to all new classes instead of thinking about cases when to add and when not to.	14 years ago
Vladimír Vondruš	19029d97c6	Tracking viewport state in Framebuffer. Viewport position and size is managed separately for each framebuffer and glViewport() is called in bind() (and also from setViewport(), if the framebuffer is currently bound) if the viewport differs from current state. If used only one framebuffer size through whole application lifetime, glViewport() doesn't need to be called at all.	14 years ago
Vladimír Vondruš	5267547373	Tracking framebuffer binding.	14 years ago
Vladimír Vondruš	5f84edf73d	Split Framebuffer into default and named framebuffers. Default framebuffer is now accessible throught defaultFramebuffer global variable, named framebuffers are handled the same way as before. All operations (clear, setViewport, blit, read) now are member functions so they cannot be mistakenly used when unwanted framebuffer is bound. Further rework (DSA, state tracking...) is on the way.	14 years ago
Vladimír Vondruš	9e24d0cb06	Cleaned up #includes.	14 years ago
Vladimír Vondruš	2acbd49e9c	Renamed Buffered{Image,Texture} to Buffer{Image,Texture}. Buffered* hinted that it has something to do with caching, streaming or whatever. "Buffer texture" is now also consistent with naming in specification.	14 years ago
Vladimír Vondruš	90ed04dc7a	Image formats rework. Renamed the enums and enum values to be consistent with OpenGL, added integer types, fixed OpenGL ES compatibility.	14 years ago
Vladimír Vondruš	5a9317085c	Moved functions not related to particular Framebuffer to Renderer class. Framebuffer::setViewport() and clear() should be non-static and operate on particular framebuffer in the future.	14 years ago
Vladimír Vondruš	43f6dbc72d	Using integer vector aliases all over the place.	14 years ago
Vladimír Vondruš	5b707d3524	Using GLfloat as default template parameter also in Color.	14 years ago
Vladimír Vondruš	8f83485653	Forward declarations for Magnum namespace in Magnum.h header.	14 years ago
Vladimír Vondruš	93a5e7230f	Use OpenGL ES 2.0 specific definitions for extension-only functionality. If targetting explicitly OpenGL ES 2.0, only gl2.h is included (not gl3.h).	14 years ago
Vladimír Vondruš	45a236fb07	Temporary workaround for extension-only functionality in ES 2.0. Will be re-enabled when some solution for extensions is done.	14 years ago
Vladimír Vondruš	9701c8dacb	If targetting exactly ES 2.0, hide everything not available there. Some target platforms supply their own OpenGL headers, thus we cannot use our own from ES 3.0 and compilation fails. On the other hand, this will be better for users as usage of unsupported features will be catched right during compilation and not at runtime.	14 years ago

Vladimír Vondruš	1077370937	Using fixed-size 8bit integer for dimension count. There can be only one, two or three dimensions, so why to use eight times larger type than needed?	14 years ago
Vladimír Vondruš	aceb93c313	Distinguish dimensions (1D, 2D, 3D) from image size.	14 years ago
Vladimír Vondruš	035bd4d376	Links to documentation of related gl*() function. Each function touching OpenGL now has list of all related functions touching OpenGL.	14 years ago
Vladimír Vondruš	0bf1b62080	Framebuffer: ability to specify which polygon facing to cull	14 years ago
Vladimír Vondruš	fe62f547de	Reduced #includes in headers. Magnum.h now doesn't include anything except OpenGL headers, thus changes in Math library don't trigger recompilation of everything, but only of things really depending on it. Math constants moved to separate file for similar reasons, de-inlined some functions to remove the need for some #includes.	14 years ago
Vladimír Vondruš	b9ed4159e0	Framebuffer: don't allow invalid bits to be present in *Mask enum sets. Now ~Framebuffer::Clear::Color is equal to Framebuffer::Clear::Depth\|Framebuffer::Clear::Stencil, which wasn't the case before, the same for BlitMask.	14 years ago
Vladimír Vondruš	685be07a8f	Removed parameter-less clear() from Framebuffer. Automatic behavior could cause harm, as the stencil/depth test could be temporarily disabled for some parts of the scene (but enabled for the rest), causing clear() to leave stencil/depth buffer untouched.	14 years ago
