Vladimír Vondruš	bef497c46a	SceneGraph rework, part 7: Drawable and Camera features. * Camera is now templated also on underlying floating-point type. * Drawable objects can be split into groups (e.g. for separated rendering of transparent objects) * Added (long time missing) test for draw() function.	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	cac85252ac	Using DimensionTraits in SceneGraph implementation. Removed equivalent typedefs from AbstractObject and replaced them with DimensionTraits.	14 years ago
Vladimír Vondruš	4aec678539	Have first letter of static constants uppercase, like previously. Lowecase didn't prove to be better, because Doxygen cannot implicitly link to it and it collides with non-type template parameters and private variables.	14 years ago
Vladimír Vondruš	dfe566886a	SceneGraph: disallow instantiation of Object and Camera base classes. Renamed them to AbstractObject and AbstractCamera to make this more evident to end user.	14 years ago
Vladimír Vondruš	cef2a19b07	Moved template list of SceneGraph objects into traits class. Beside better readability it is now more future proof, as objects with double types etc. and new templated types can be added more easily.	14 years ago
Vladimír Vondruš	7d3435f483	SceneGraph: method chaining also for Camera. Mention it also in documentation to hint users to use it.	14 years ago
Vladimír Vondruš	268f678221	SceneGraph: Camera aspect ratio was not fixed after changing policy. Also added test for projectionSize(), which couldn't be added before because of gl*() calls.	14 years ago
Vladimír Vondruš	e1c22b9ca2	Don't do anything OpenGL-related inside Camera itself. * The user might not want to call Framebuffer::clear(), because there could be something already rendered with another camera. * The user might not want to call Framebuffer::setViewport(), because there could be different framebuffer attached.	14 years ago
Vladimír Vondruš	90881e7337	New base for matrices and vectors: RectangularMatrix. Currently moved only non-square functionality from Matrix there. Also static constant members such as row/column count and size are now lowercase, as they are variables, not types.	14 years ago
Vladimír Vondruš	5c80fb0ad9	GCC 4.5 compatibility: cannot use initializer list here.	14 years ago
Vladimír Vondruš	236e0abc58	Camera: computing projection scale directly from projection matrix. Storing scale as independent (and inverted) value and updating it separately from projection matrix is just plain wrong.	14 years ago
Vladimír Vondruš	e1641fb5c1	Doc++	14 years ago
Vladimír Vondruš	4a207c6556	Simplified camera projection matrix creation. It doesn't need to be decomposed in many matrix multiplications which still fail to go properly together.	14 years ago
Vladimír Vondruš	58abfdeeee	SceneGraph: Using linked list from Corrade instead of std::set. Resulting (debug) executables are ~100 kB smaller, all operations which were previously logarithmic are now done in constant time and the whole implementation is a lot simpler.	14 years ago
Vladimír Vondruš	af8b01da88	SceneGraph: default Camera aspect ratio policy is to not preserve. I thought and believed it was like that since forever, but I was wrong.	14 years ago
Vladimír Vondruš	d43e18a741	Initial support for 2D scene graph.	14 years ago
Vladimír Vondruš	c6e14dd348	SceneGraph: Initial support for projections with aspect ratio != 1:1. Orthographic projection done, perspective projection needs total rework, leaving it for later.	14 years ago
Vladimír Vondruš	27bbf23dff	SceneGraph: Simplified Implementation::Camera<3>::fixAspectRatio().	14 years ago
Vladimír Vondruš	810c06509a	SceneGraph: modifications to allow 2D implementation in future.	14 years ago
Vladimír Vondruš	e3ee7b487b	Moved Object, Scene and Light to separate SceneGraph library.	14 years ago
Vladimír Vondruš	7f55f30ced	CORRADE_ASSERT() now needs semicolon after.	14 years ago
Vladimír Vondruš	51aa660f6c	Decoupled framebuffer operations from Camera class. Now it is possible to render without using any Object, Scene or Camera classes. Framebuffer class now manages features, clearing and setting viewport. Added position parameter to setViewport(), ability to clear specified features in clear().	14 years ago
Vladimír Vondruš	a32498361c	Camera::setClearColor() is now static. Removed getter.	14 years ago
Vladimír Vondruš	9d39808a84	Better Camera clearing. Now it is exposed as protected function, so it can be called from subclasses. It now clears() only set features, so when stencil or depth test is not enables, it doesn't clear their buffers.	14 years ago
Vladimír Vondruš	5381d9e423	Camera: stronly typed AspectRatioPolicy enum.	14 years ago
Vladimír Vondruš	f53e840ecd	Camera must be attached to scene when attempting to draw.	14 years ago
Vladimír Vondruš	d65d33912a	Improved Object transformation caching to reuse absolute transformation. Object::setClean() now computes absolute transformation while traversing through object parents and passes it as parameter to clean(), which is now virtual a meant to be reimplemented instead of setClean(). Updated and greatly improved unit test.	14 years ago
Vladimír Vondruš	ccf61c0f7f	Fixed typo in method name.	14 years ago
Vladimír Vondruš	c14715962d	Use T() instead of static_cast<T>() for numeric types.	14 years ago
Vladimír Vondruš	7b780b9f9b	Added missing const to camera matrix.	14 years ago
Vladimír Vondruš	e8c76b7d96	Forced exclusive use of bracket operators in Matrix and Vector. Removed functions at(), set() and add(), everything (and more) can be now done using operator[]. Accessing matrix elements is now done through column vectors, e.g.: Matrix4 a; a.at(row, col); // before a[col][row]; // now Note that because operator[] on Matrix returns column vector (there is nothing like row vector), the parameter "order" is now swapped.	14 years ago
Vladimír Vondruš	83150f003e	Using noun instead of verb for inverse matrix function. Mainly to be consistent with Matrix::transposed() function name, furthermore calling Matrix::inverse() could look like the original matrix is being inversed, while calling Matrix::inversed() implies that the function doesn't change the original matrix, but returns the result instead.	14 years ago
Vladimír Vondruš	b6ac0125dc	"Initializer-list" constructor also for Matrix.	14 years ago
Vladimír Vondruš	7911c22eff	Removed convenience functions with "unwrapped" Vector parameters. With C++11, objects can be passed nearly as easy as without these convenience functions, for example: Matrix4::scaling({0.5f, 1.0f, 0.5f}); which is nearly the same as the following, using convenience function: Matrix4::scaling(0.5f, 1.0f, 0.5f); Convenience functions can also be pretty confusing, for example: Matrix4::rotation(1.0f, -1.0f, 2.0f, 2.0f); // wtf? Matrix4::rotation(1.0f, {-1.0f, 2.0f, 2.0f}); // ah, okay! There are also a few neat tricks, which cannot be done using convenience functions, for example: Matrix4::translate(Vector3::xAxis(3.0f)); // {3.0f, 0.0f, 0.0f} Camera::setClearColor({0.1f, 0.1f, 0.1f}); // default 1.0f for alpha	14 years ago
Vladimír Vondruš	a64fbfbe63	Use OpenGL-compatible types in camera viewport size.	14 years ago
Vladimír Vondruš	e98ca5b03a	Moved drawing functions from Scene to Camera. Also removed non-trivial orthographic projection and clear color defaults, addded GL_STENCIL_BUFFER_BIT to glClear().	14 years ago
Vladimír Vondruš	0945c50aa6	Removed "active camera" from Scene. It was overengineered and unnecessarily complicated. Now the camera is specified only in Scene::draw(), which eliminates all the needs for recalculating absolute object transformations on each camera transformation change. Absolute object transformation is now computed relative to root object or relative to camera object passed as parameter. Because of that it is now also possible to draw the scene using multiple cameras at once.	14 years ago
Vladimír Vondruš	34a84dc677	Using nullptr instead of 0.	14 years ago
Vladimír Vondruš	b945f5f68b	Happy New Year.	15 years ago
Vladimír Vondruš	4a23efa307	Use Vector2<unsigned int> for viewport size in Camera instead of ints.	15 years ago
Vladimír Vondruš	e5e7d95af4	Using nullptr instead of 0 everywhere.	15 years ago
Vladimír Vondruš	8c004ef77d	Getters for near and far camera clipping plane.	15 years ago
Vladimír Vondruš	c7b331d100	(Ahem...) Happy New Year!	15 years ago
Vladimír Vondruš	38d4c8581c	Finally, camera matrix. As matrix inversion is costly operation, the matrix is cached, so it's regenerated only when the transformation / parent is changed.	16 years ago
Vladimír Vondruš	3f02de7ce1	Renamed AbstractObject -> Object, draw() is now dummy instead of pure virtual.	16 years ago
Vladimír Vondruš	9b6f3582e3	Orthographic and perspective camera projections.	16 years ago
Vladimír Vondruš	9fd97e2f96	Customizable camera aspect ratio handling policy.	16 years ago
Vladimír Vondruš	9cd1e7c12a	Scene class and dummy Camera class.	16 years ago
Vladimír Vondruš	c41d6ad582	New namespace Magnum::Math.	16 years ago
