Graphics APIs

The NDK currently supports the following graphics APIs. A graphics API type must be provided to tiltfive::Glasses::reserve() (C++) or t5Reserve() (C).

The below table shows the possible types as well as the meaning of the T5_ConnInfo::graphicsContext parameter that is also specified in the associated reserve call.

Graphics API	Meaning	Context	Texture Handle
kT5_GraphicsApi_None	No graphics API - frames will not be sent to the glasses	null (Not used)	null (Not used)
kT5_GraphicsApi_GL	OpenGL	T5_GraphicsContextGL*	The name of a texture object that can be bound to the GL_TEXTURE_2D or GL_TEXTURE_2D_ARRAY target.
kT5_GraphicsApi_D3D11	Direct3D 11 (Windows Only)	ID3D11Device*	A pointer to an ID3D11Texture2D object.
kT5_GraphicsApi_Vulkan	Vulkan	T5_GraphicsContextVulkan*	A pointer to an VkImage or VkImageView object handle.

Note

Note that for an OpenGL graphics API texture handle field values should be the name of the texture; they should NOT point to a value containing name of the texture even though the field type is void*.

This list is not final - additional graphics APIs may be added. Further documentation about graphics APIs will appear here.
