Detailed Description

Decoder of Yuv encoded texture into a new texture.

Member Function Documentation

◆ setKey()

void gramods::gmGraphics::ChromaKeyTexture::setKey ( gmCore::float3 key )

Set the RGB key to mask with.

Default is [0, 1, 0].

XML-attribute: key

◆ setTexture()

void gramods::gmGraphics::ChromaKeyTexture::setTexture ( std::shared_ptr< TextureInterface > texture )

Sets the texture to decode.

◆ setTolerance()

void gramods::gmGraphics::ChromaKeyTexture::setTolerance ( gmCore::float2 tol )

Set the minimum and maximum tolerances against the key when masking.

This will specify a ramp in decimal CrCb (2D) color space. Default is [0.48, 0.50].

XML-attribute: key

◆ traverse()

void gramods::gmGraphics::ChromaKeyTexture::traverse ( Visitor * visitor )

overridevirtual

Propagates the specified visitor.

See also: Object::Visitor

Reimplemented from gramods::gmCore::Object.

◆ updateTexture()

GLuint gramods::gmGraphics::ChromaKeyTexture::updateTexture	(	size_t	frame_number,
		Eye	eye
	)

overridevirtual

Updates the texture and returns the ID of the associated GL texture object.

Must be called with GL context. Observe also that this method may perform off-screen rendering.

Parameters

frame_number	The current frame being rendered. This number should increment by one for each frame, however it may wrap around and start over at zero.
eye	Eye for which the texture is requested. An implementation may use different textures for different eyes or may reuse the same texture for all eyes.

Returns: OpenGL texture ID of the updated texture

Implements gramods::gmGraphics::TextureInterface.
