Methods Description
Ray Camera::castRay (float x, float y)
Returns ray with origin point in camera position and direction to projection plane with x and y coordinates.
Vector4 Camera::color () const
Returns the color with which the screen will be cleared.
See also setColor().
Camera * Camera::current ()
Returns current active camera.
See also setCurrent().
float Camera::farPlane () const
Returns a distance to far cut plane.
float Camera::focal () const
Returns a focal distance for the camera.
See also setFocal().
float Camera::fov () const
Returns field of view angle for the camera in degrees.
See also setFov().
std::array<Vector3, 8> Camera::frustumCorners (Camera & camera)
Returns frustum corners for the camera.
std::array<Vector3, 8> Camera::frustumCorners (bool ortho, float sigma, float ratio, Vector3 & position, Quaternion & rotation, float nearPlane, float farPlane)
Returns frustum corners with provided parameters. This function accepts a list of parameters: ortho is a flag that points ortho*graphic or perspective camera. *sigma is an angle of frustum or ortho size in the case of an ortho*graphic camera. *ratio is an aspect ratio. position of the frustum in world space. rotation of frustum in world space. nearPlane clipping plane. farPlane clipping plane.
float Camera::nearPlane () const
Returns a distance to near cut plane.
float Camera::orthoSize () const
Returns camera size for orthographic mode.
See also setOrthoSize().
bool Camera::orthographic () const
Returns true for the orthographic mode; for the perspective mode, returns false.
See also setOrthographic().
Transforms position from worldSpace into screen space. Returns result of transformation.
Matrix4 Camera::projectionMatrix () const
Returns projection matrix for the camera.
float Camera::ratio () const
Returns the aspect ratio (width divided by height).
See also setRatio().
void Camera::setColor (Vector4 color)
Sets the color with which the screen will be cleared.
See also *color*().
void Camera::setCurrent (Camera * current)
Sets current active camera.
See also *current*().
void Camera::setFar (float distance)
Sets a distance to far cut plane.
void Camera::setFocal (float focal)
Sets a focal distance for the camera.
See also *focal*().
void Camera::setFov (float angle)
Sets field of view angle for the camera in degrees.
Note: Applicable only for the perspective mode.
See also fov().
void Camera::setNear (float distance)
Sets a distance to near cut plane.
void Camera::setOrthoSize (float size)
Sets camera size for orthographic mode.
See also orthoSize().
void Camera::setOrthographic (bool mode)
Sets orthographic mode.
See also orthographic().
void Camera::setRatio (float ratio)
Sets the aspect ratio (width divided by height).
See also *ratio*().
Transforms position from screenSpace into world space. Returns result of transformation.
Matrix4 Camera::viewMatrix () const
Returns view matrix for the camera.
