Vladimír Vondruš	1693c772ad	Moved OpenGL includes out from Magnum.h. OpenGL includes are ~35k lines together and it is a waste of compilation time to include them even if they are not needed at all (e.g. whole SceneGraph and Physics libraries). Saves ~10s of compilation time (6:46 before, now 6:35).	13 years ago
Vladimír Vondruš	2d2d1c07f4	Using new type aliases in whole root Magnum namespace.	13 years ago
Vladimír Vondruš	3379e6c794	Ability to send less than all attribute components to the shader. Remaining unspecified components are set to 0, 0, 1, according to spec. Also cleaned up and simplified the internals, added debug output operators for attribute component count and types and tested the whole thing.	13 years ago
Vladimír Vondruš	24bd924aa5	Consistent naming of attribute types in AbstractShaderProgram.	13 years ago
Vladimír Vondruš	6e61354fde	OpenGL ES compilation fixes.	13 years ago
Vladimír Vondruš	9ffb8081f3	Got rid of TypeTraits class altogether.	13 years ago
Vladimír Vondruš	a9d25c995f	Mesh: fixed attribute stride computation. The stride was computed always for resulting GLSL type (e.g. vec4) even if the data were of anoother type (e.g. std::uint8_t[4]). The code is exceptionally ugly now, time to wrap it with unit tests.	13 years ago
Vladimír Vondruš	0f889369f4	No `using namespace std` anywhere. Also added missing std:: prefix to remaining cases of std::size_t, std::[u]int[0-9]+_t, std::sin() etc., std::exit().	14 years ago
Vladimír Vondruš	a636792b19	AbstractShaderProgram: query for max supported attribute count.	14 years ago
Vladimír Vondruš	29893ebe82	Updated OpenGL ES support in shaders.	14 years ago
Vladimír Vondruš	eb0565b5d9	Minor code cleanup.	14 years ago
Vladimír Vondruš	beea8235b1	Using EXT_direct_state_access/ARB_separate_shader_objects for uniforms. Also explicitly calling use() on default (non-DSA) setUniform() implementation. Because of that, it is now possible to conveniently call use() at the end, instead of at the beginning of uniform setting chain, for example: // before shader->use(); shader->setTransformation(transformation) ->setProjection(projection) ->setColor(color); // now shader->setTransformation(transformation) ->setProjection(projection) ->setColor(color) ->use(); Note that you still have to explicitly call use(), because if DSA is available, no use() is called explicitly on any setUniform(). If DSA is not available, use() is called on first setUniform() and subsequent calls have no negative performance impacts.	14 years ago
Vladimír Vondruš	2dde4b9bf8	Tracking AbstractShaderProgram state. Reduces OpenGL call count when subsequently using the same shader for rendering.	14 years ago
Vladimír Vondruš	2595974fae	Refactoring of internal OpenGL object names.	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	ee55d8425c	Added AbstractShaderProgram::bindFragmentDataLocationIndexed().	14 years ago
Vladimír Vondruš	7f55f30ced	CORRADE_ASSERT() now needs semicolon after.	14 years ago
Vladimír Vondruš	c7bb153d0a	Port to OpenGL ES 2. Desktop OpenGL and OpenGL ES 2 support can be switched using CMake TARGET_GLES option. All functionality not supported in ES is marked in documentation. If targetting OpenGL ES, GLES2/gl2.h is included instead of GLEW. Mesh class now uses VAOs only in desktop OpenGL, in ES the buffers are bound on each draw call.	14 years ago
Vladimír Vondruš	e868d8e03c	Deprecating AbstractShaderProgram::bind*Location(). Preferred workflow is to specify attribute location explicitly in the shader. The functions remains here as some old Intel systems don't support the required extension ARB_explicit_attrib_location (and it's not in GL 3.0 either). Also updated and fixed the documentation. Function bindAttribute() was renamed to bindAttributeLocation() to be consistent with bindFragmentDataLocation(). PhongShader now uses explicit attribute location.	14 years ago
Vladimír Vondruš	39a313a357	Brought debug facilities from Corrade::Utility to Magnum namespace. These classes are used so frequently that it is counterproductive to not have them here.	14 years ago
Vladimír Vondruš	54a2c47408	Create and delete shaders and programs only on construction/destruction. Also inlined some simple functions, updated documentation.	14 years ago
Vladimír Vondruš	43c0016ed3	Move semantic for Shader class. The class is now created always on the stack, so the user doesn't have to delete it explicitly. It's now possible to write less verbose shader code, instead of three lines before: Shader* s = Shader::fromFile(Shader::Fragment, "Shader.frag"); attachShader(s); // ... delete s; It's now only one: attachShader(Shader::fromFile(Shader::Fragment, "Shader.frag"));	14 years ago
Vladimír Vondruš	2b7aa09520	Added some TODOs.	14 years ago
Vladimír Vondruš	64665872cc	Use CORRADE_ASSERT() instead of cassert and direct error output. Unlike previous solution this can be compiled without any impact on performance at all.	14 years ago
Vladimír Vondruš	49c809915f	Added function to bind fragment data locations.	14 years ago
Vladimír Vondruš	57ae567a36	Simplified attribute binding in AbstractShaderProgram. Removed another old overdone code, the attributes are now bound directly, without saving the data to some temporary location and then binding everything at once in link().	14 years ago
Vladimír Vondruš	45200899ed	Assertion fail when user is doing something wrong with shaders. Non-assertion-failing error switched to warning, as it is not fatal.	14 years ago
Vladimír Vondruš	d8943b898c	Use nullptr instead of 0 for pointers.	14 years ago
Vladimír Vondruš	8cc445d164	Using own Corrade::Debug class instead of cerr in Shaders. Also improved and unified the messages and added messages when uniformLocation() fails or attribute is bound after linking.	14 years ago
Vladimír Vondruš	b945f5f68b	Happy New Year.	15 years ago
Vladimír Vondruš	c7b331d100	(Ahem...) Happy New Year!	15 years ago
Vladimír Vondruš	1d5d4ddcb4	Renamed AbstractShaderProgram::{load -> attach}Shader().	16 years ago
Vladimír Vondruš	3444f62638	Classes for compiling and using shaders.	16 years ago
