Detailed Description

SphereGeometry contains information for projection of graphics on a sphere.

This can be used for view correction of rendering in dome theatres.

Member Function Documentation

◆ getCameraFromPosition()

bool gramods::gmGraphics::SphereGeometry::getCameraFromPosition	(	Camera	vfrustum,
		Eigen::Vector3f	position,
		Camera &	rfrustum
	)

overridevirtual

Calculates and returns a frustum, with optical center at the specified position, that contains the intersection between the provided frustum and the geometrical shape.

Parameters

[in]	vfrustum	The view frustum, typically the frustum of a projector that projects onto a geometrical surface.
[in]	position	The rendering position, that will be the position of the returned render frustum.
[out]	rfrustum	The render frustum, a frustum that will provide a rendering of the scene, from the provided position, onto the geometry where this geometry is seen by the vfrustum frustum.

Returns: True if a camera could be specified and false if there is no valid camera that fulfills the requirements.

Reimplemented from gramods::gmGraphics::Geometry.

◆ getIntersectionCode()

std::string gramods::gmGraphics::SphereGeometry::getIntersectionCode ( )

overridevirtual

Returns shader code that implements the necessary functions for the specific Geometry.

The code implements

vec3 getIntersection(vec3 pos, vec3 dir) - returns the intersection between the line defined by the specified position and direction vector and the SphereGeometry. Return (0,0) if there is no intersection.

Reimplemented from gramods::gmGraphics::Geometry.

◆ setFrustumSizeRatio()

void gramods::gmGraphics::SphereGeometry::setFrustumSizeRatio ( float r )

Until the render frustum estimation has been implemented to correctly cover the full view frustum, this frustum size modulation parameter can be used to enlarge the render frustum.

Use this if you see D-shaped black regions at the edge of the view. Default is 1.0.

XML-attribute: frustumSizeRatio

◆ setMapperUniforms()

void gramods::gmGraphics::SphereGeometry::setMapperUniforms ( GLuint program )

overridevirtual

Called by the code that is using this geometry object, to let the it set the uniforms used by the mapper code.

Reimplemented from gramods::gmGraphics::Geometry.

◆ setPosition()

void gramods::gmGraphics::SphereGeometry::setPosition ( Eigen::Vector3f p )

Set the position of the sphere origin, its center.

XML-attribute: position

See also: gramods::operator>>(std::istream &, Eigen::Vector3f &)

◆ setRadius()

void gramods::gmGraphics::SphereGeometry::setRadius ( float r )

Set the radius of the sphere.

XML-attribute: radius
