Detailed Description

Camera (modelview projection matrix manipulation)

Member Enumeration Documentation

enum ome::qtwidgets::GLView2D::Camera::ProjectionType

Projection type.

Enumerator
ORTHOGRAPHIC	Orthographic projection.
PERSPECTIVE	Perspective projection.

Member Function Documentation

glm::mat4 ome::qtwidgets::GLView2D::Camera::mvp ( ) const

inline

Get modelview projection matrix.

The separate model, view and projection matrices are combined to form a single matrix.

Returns

the modelview projection matrix.

References model.

Here is the caller graph for this function:

float ome::qtwidgets::GLView2D::Camera::rotation ( ) const

inline

Get rotation factor.

Returns

the rotation factor (in radians).

Referenced by ome::qtwidgets::GLView2D::timerEvent().

Here is the caller graph for this function:

float ome::qtwidgets::GLView2D::Camera::zoomfactor ( ) const

inline

Get zoom factor.

Convert linear signed zoom value to a factor (to the 10th power of the zoom value).

Returns

the zoom factor.

Todo:

remove fixed size.
