Tulip OpenGL camera object.
This camera can be a 2D or 3D camera After setup you can do some basic operation :
tlp::Camera::Camera | ( | GlScene * | scene, |
Coord | center = Coord(0, 0, 0) , |
||
Coord | eyes = Coord(0, 0, 10) , |
||
Coord | up = Coord(0, -1, 0) , |
||
double | zoomFactor = 0.5 , |
||
double | sceneRadius = 10 |
||
) |
Constructor.
scene | A layer is attached to a scene so we have to specify it in the constructor |
center | 3D coordinates of point visualized by the camera |
eye | 3D position of the camera |
up | normalized up 3D coordinates of the camera |
zoomFactor | level of zoom of the camera |
sceneRadius | scene radius of the camera |
tlp::Camera::Camera | ( | GlScene * | scene, |
bool | d3 | ||
) |
Constructor : used to create a 2D camera.
|
override |
Destructor.
BoundingBox tlp::Camera::getBoundingBox | ( | ) | const |
Return the camera bounding box.
This bounding box is the part of the scene visualized by this camera.

const Vector<int, 4>& tlp::Camera::getViewport | ( | ) | const |
Return the viewport of the attached scene.
|
virtual |
Function to export data in outString (in XML format)

void tlp::Camera::move | ( | float | speed | ) |
This function moves the camera forward or backward depending on the speed.
void tlp::Camera::rotate | ( | float | angle, |
float | x, | ||
float | y, | ||
float | z | ||
) |
This function rotates the camera's eyes around the center depending on the values passed in.
|
inline |
void tlp::Camera::setCenter | ( | const Coord & | center | ) |
Set the center.
3D coordinates of point visualized by the camera
void tlp::Camera::setEyes | ( | const Coord & | eyes | ) |
Set the eye.
3D position of the camera
void tlp::Camera::setScene | ( | GlScene * | scene | ) |
Set the camera's scene The viewport is store in the scene, so we must attach camera to a scene.
void tlp::Camera::setUp | ( | const Coord & | up | ) |
Set the up vector.
normalized up 3D coordinates of the camera
|
virtual |
Function to set data with inString (in XML format)
void tlp::Camera::setZoomFactor | ( | double | zoomFactor | ) |
Set the zoom factor.
level of zoom of the camera
void tlp::Camera::strafeLeftRight | ( | float | speed | ) |
This function strafes the camera left and right depending on the speed (-/+)
void tlp::Camera::strafeUpDown | ( | float | speed | ) |
This function strafes the camera up and down depending on the speed (-/+)
Coord tlp::Camera::viewportTo3DWorld | ( | const Coord & | point | ) | const |
Return the 3D world coordinate for the given viewport point.
|
inline |
Coord tlp::Camera::worldTo2DViewport | ( | const Coord & | obj | ) | const |
Return the viewport position for the given 3D coordinate.
