Michael Fabian 'Xaymar' Dirks 3e97906b32 gs-vertex: Always align to 16-byte 2018-01-08 17:30:33 +01:00
Michael Fabian 'Xaymar' Dirks f721ad0f19 util-math: Fix standalone compilation issues 
All libobs files must be loaded with libobs/... instead of directly.

Michael Fabian 'Xaymar' Dirks a3d859fb4f util-math: Implement aligned vec3 and vec4 versions 
A bug in Visual C++ 2013 32-bit & 2015 32-bit causes the C++ compiler to incorrectly align the vec3 and vec4 structs to 8-byte instead of 16-byte, resulting in a crash if the target PC supports SSE. Visual Studio 2017 and 64-bit builds are not affected.

Michael Fabian 'Xaymar' Dirks add8012549 source-mirror: Add a Source Mirror source 
The source allows you to apply effects to the same source without requiring a new instance of the source. Any changes done to the original source also apply to the mirror, so there is less total work that needs to be done.

It can also rescale the source, allowing you to use the same source as a cheap instant backdrop with Blur for example. What you do in the end is completely unwritten and up to you to decide.

Michael Fabian 'Xaymar' Dirks e7bbb213a4 filter-blur: Fix Blur filter occasionally not rendering 
An earlier commit changed how Blur filter rendered and thus m_technique was no longer being initialized, resulting in the check randomly failing if the memory was just right.

This also adds some more extra logging to the instance creation in case things fail and fixed one MSVC warning.

Michael Fabian 'Xaymar' Dirks c7cfbff7dd gs-vertexbuffer: Workaround for a foreign deallocation bug in libobs 
The graphics subsystem in OBS is freeing memory it didn't allocate, resulting in stack/heap corruption and other kinds of messy situations. The official "fix" for this is to use bmalloc, but then you lose any kind of ability to re-use the same buffer for multiple vertex buffers or update on the fly without adjusting code that is possibly outside of your control (such as in libraries).

This works around the issues by "patching" the gs_vertexbuffer object to no longer hold a reference to the gs_vb_data object. Currently only D3D11 is supported for this kind of hack and it might break in a future obs-studio release.

Michael Fabian Dirks 88cc142afb gs, effects: Anisotropic Mipmapper Class 
End goal of this is to be an anisotropic filtering purely on the GPU without any actual mipmaps in the graphics subsystem. The basic idea behind it is that we can create all possible mipmaps in a twice as big texture as the original and then can efficiently render it no matter the GPU features as it will only consume one sampler.

The texture that it outputs will have both horizontal, vertical and full mipmaps in it. Horizontal mipmaps reduce Width, Vertical mipmaps reduce Height and full mipmaps reduce both. This means that LoD levels are both possible in the X and Y direction, allowing for much greater precision mipmapping on all GPUs.

This is a temporary solution until we can directly copy updated textures to a mipmap level.

Michael Fabian Dirks 9967a6ebf0 filter-blur: Add Color Format option 
This option allows applying the blur to other color formats such as YUV. Bilateral Blur benefits the most from this, resulting in smoother images at lower kernel sizes.
