CYIOrthographicCameraSceneNode Class Reference

Detailed Description

In 3D rendering, a camera is something that defines a view and a projection using a pair of matrices. This class provides the APIs and behaviours describing the projection component of a camera. See the base class CYIAbstractCameraSceneNode for the definition of the "view" component of a camera.

An orthographic transformation is a 2D projection in which parallel lines remain parallel and there is no vanishing point. The camera's viewing volume is a rectangular prism and objects are rendered the same size regardless of distance to the camera.

     |       |

[]o | | |_______|

A standard way of defining an orthographic projection is by specifying the top, left, bottom, and right of a viewing volume.

Member Function Documentation

◆ BuildDefaultCamera()

static std::unique_ptr<CYIOrthographicCameraSceneNode> CYIOrthographicCameraSceneNode::BuildDefaultCamera ( const CYIString name)

Create a named orthographic camera scene node.

Callers own the returned CYIOrthographicCameraSceneNode.

◆ CalculateProjectionMatrix()

virtual glm::mat4 CYIOrthographicCameraSceneNode::CalculateProjectionMatrix ( ) const

Subclasses must implement this function to return their calculated projection matrix. This function will be called if the result of IsProjectionDirty() is true on a given frame.

Implements CYIAbstractCameraSceneNode.

◆ ConfigureOrthographic()

static void CYIOrthographicCameraSceneNode::ConfigureOrthographic ( CYIOrthographicCameraSceneNode pCamera,
float  regionOfInterestDistance,
float  regionOfInterestWidth,
float  regionOfInterestHeight 

The provided camera will have its view modified to encompass the specified region.

◆ GetBounds()

const YI_FLOAT_RECT& CYIOrthographicCameraSceneNode::GetBounds ( ) const

Returns the bounds of the orthographic projection.

See also

◆ GetDumpTreeString()

virtual CYIString CYIOrthographicCameraSceneNode::GetDumpTreeString ( ) const

Returns a string containing useful information about this node, displayed by DumpTree

Subclasses can implement this method to specify different or additional information. Appending to the default string is recommended.

See also

Reimplemented from CYIAbstractCameraSceneNode.

◆ SetBounds()

void CYIOrthographicCameraSceneNode::SetBounds ( const YI_FLOAT_RECT bounds)

Set the bounds of the orthographic projection.

The environment viewed by the camera will be mapped to a rectangular region bounded by the left, top, right, and bottom of the camera.

An orthographic projection is a projection in which parallel sides remain parallel regardless of the position or orientation of the objects depicted.
