Detailed Description

The TextureProjectedView uses a texture to define the 3D position of each render target buffer pixel, and then projects the specified renderers onto this "surface", from the viewpoint.

This is useful for rendering a dynamic view on a static projection surface.

Member Function Documentation

◆ renderFullPipeline()

void gramods::gmGraphics::TextureProjectedView::renderFullPipeline	(	ViewSettings	settings,
		Eye	eye
	)

overridevirtual

Appends local renderers to the view settings, renders the views and projects the result onto the texture's "surface", from the viewpoint.

Implements gramods::gmGraphics::MultiscopicView.

◆ setBufferResolution()

void gramods::gmGraphics::TextureProjectedView::setBufferResolution ( gmCore::size2 R )

Sets the resolution of the intermediate buffer, in pixels.

Default is 2048 x 2048.

XML-attribute: bufferResolution

◆ setEdgeToEdge()

void gramods::gmGraphics::TextureProjectedView::setEdgeToEdge ( bool on )

De/activates edge-to-edge mode.

If set to true, the middle of the border texel values of the texture correspond to the location of the edge of the pixel buffer to render to. Default is false, meaning that standard OpenGL texture coordinate behavior is used, which probably is what you want if your texture has the same resolution as the render target buffer.

XML-attribute: edgeToEdge

◆ setLinearInterpolation()

void gramods::gmGraphics::TextureProjectedView::setLinearInterpolation ( bool on )

Turn on or off linear interpolation in the projection from linear graphics to non-linear projection space.

Default is off.

XML-attribute: linearInterpolation

◆ setTexture()

void gramods::gmGraphics::TextureProjectedView::setTexture ( std::shared_ptr< TextureInterface > tex )

Sets the Texture to use for warping coordinates.

XML-attribute: texture

◆ setWarpOffset()

void gramods::gmGraphics::TextureProjectedView::setWarpOffset ( Eigen::Vector3f offset )

Sets an offset to add to the texture values, so that the 3D position is calculated by p' = p * scale + offset.

Default is [ 0, 0, 0 ].

XML-attribute: warpOffset

◆ setWarpScale()

void gramods::gmGraphics::TextureProjectedView::setWarpScale ( Eigen::Vector3f scale )

Sets a scaling to the texture values, so that the 3D position is calculated by p' = p * scale + offset.

Default is [ 1, 1, 1 ].

XML-attribute: warpScale

◆ traverse()

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

overridevirtual

Propagates the specified visitor.
